NSF Drinking Water Certified Water Stop Foam - P2002 Pro-Kit

Rush Delivery and On the Job Training

This newer water treatment plant has the capacity to meet the needs of the growing city’s population and industrial demands. It utilizes state-of-the-art technology to reduce seasonal taste and odor issues, treats for sulfates from Devils Lake discharges, and meets regulatory requirements related to pharmaceuticals, pesticides and herbicides. Located in a harsh climate, the Treatment Plant is an all indoor facility with multiple basins for the various processes of treatment.

A SealBoss Technical made a rush delivery of a P2002 Pro-Kit and NSF Drinking Water Contact Certified SealBoss Water Stop Foam to the North Dakota Water Treatment Plant where previous attempts to mitigate various leaks through concrete cracks had failed. SealBoss provided intensive on the job crack injection training for the in-house maintenance and repair team to provide them with product and application knowledge to be able to inject and leak-seal any cracks within the facility successfully.

The chlorine basin had developed cracks and water with minimal solids had been leaking from the bottom of the basin on to the pumps and other mechanical components. Previously, the leaking cracks had been unsuccessfully addressed by a contractor with a undisclosed product and were found to be covered with an epoxy paste.

Prior to injection with SealBoss hydro active hydrophobic polyurethane foam the face of the concrete needed to be cleaned and stripped back to bare concrete. Some leaking areas had previously been injected by drilling directly into the crack (which is not a recommended procedure for this type of application) and were left unfinished with some ports or parts thereof still in place. The old remaining ports needed to be removed and the old drill holes were quickly and temporarily plugged with SealBoss 3/8” Hammer-in ports.

Once this was accomplished, new injection holes were drilled following the SealBoss 1, 2, 3, 45-Degree Injection Guidelines and starting roughly 6” from the center of the crack and placing packers in a staggered fashion. Under the job site conditions the SealBoss 45-Degree packer installation technique provided for much better product penetration and travel within the cracks and hairline fissures. Once all the holes were drilled the SealBoss Evolution 13-100AL aluminum packers were placed and the overhead injection began.

SealBoss NSF/ANSI 61 certified 1510 Water Stop Foam chemical grout is approved by the supervising engineering firm for the crack and leak-seal repair on this project. The product was injected with the SealBoss P2002 high pressure single component injection pump system.

Within a short time the low viscosity SealBoss 1510 Foam was traveling through the cracks and began reacting. Refusal of the resin from the face of the crack was visible at distances far exceeding the next packer hole indicating very good penetration.

Utilizing the SealBoss 1, 2, 3, 45-Degree Injection Method with staggered packer placement, rather than drilling directly into the cracks, the low viscosity SealBoss 1510 chemical grout was able to travel much farther inside the cracks, hairline fissures and non-visible shrinkage cracks thus creating an immediate and permanent seal.

SealBoss provided intensive on-the-job crack injection training for the in-house maintenance and repair team and taught them all the product and application knowledge to be able to inject and leak-seal any cracks within the facility successfully.

fter several hours of on-site guidance, the facility’s repair team felt confident in devising a strategy to address the remaining cracks. They were also well-acquainted with the systems for anticipated future leak repairs.

Efflorescence and Leaks

Efflorescence – Indicator of Water Problems in Structures

Efflorescence, at first glance, may seem like a simple aesthetic issue. It presents itself as a white or occasionally vibrant and colorful, chalky residue on walls, especially around cracks and joints. This substance can evolve, often resembling delicate, hair-like filaments. Yet, beyond its surface appearance, efflorescence strongly signals the presence of a water leak.

A crack with efflorescence built-up has to be considered a leaking crack.

What exactly is efflorescence?

Efflorescence is the result of a variety compounds that have been dissolved and transported by water. When this water reaches the surface of materials like concrete or masonry, it evaporates, leaving behind minerals, metals and inorganic compounds, such as calcium hydroxide which interacts with atmospheric carbon dioxide to form fine calcium carbonate crystals.

The result is the characteristic residue which is mostly greyish or white. However, it can sometimes appear colorful if the water causing the efflorescence contains minerals or compounds that produce colors when they crystallize. Copper salts often yield blue or green efflorescence. Similarly, iron salts can lead to yellow, brown, or reddish hues, while manganese can give rise to pink or purple shades.

The presence of these or other metal ions in the water can lead to colorful efflorescence. These ions may come from the soil, water supply, or even from the building materials themselves. Therefore, colorful efflorescence not only indicates a moisture issue but could also point to the presence of specific minerals or contaminants in the environment.-

While efflorescence itself might not be harmful, it is a beacon signaling a potential moisture problem. As water continues to seep into building materials, it does not just evaporate from the surface. The moisture can be absorbed deeper into the material, leading to a process known as wicking. Over time, this persistent moisture can compromise the structural integrity of the building materials.

For inspectors and concrete repair contractors alike, recognizing efflorescence is crucial. It is not just about identifying a water leak; it is about understanding the capillary forces at play and the distribution of water within the structure that will cause the damage. By educating their clients about efflorescence, inspectors can provide valuable insights into potential problems that already may exist, even when the structure appears to be dry on the outside.

In summary, efflorescence is an indicator for moisture problems in a structure, even when it appears to be dry at the time of inspection. It forms when water with dissolved salts evaporates from concrete or masonry surfaces, leaving a white, greyish or even colorful residue. It is a a clear signal of deeper moisture problems, past and present, that can have long-term implications for the structural health of a building.

When it comes to polymer crack injection and structural repairs, understanding and addressing the root causes of efflorescence is essential.

Efflorescence and Crack Injection Repair
A Case Study at International Airport's Reservoir

Introduction
We know that efflorescence is a clear indicator of moisture issues within a structure. Its presence can signify past leakage, even when the surface appears dry. Addressing efflorescence build-up and active leaks can be crucial for the longevity of concrete structures.

This short case study highlights a repair project at an International Airport, highlighting the solutions in association with efflorescence and crack injection repair.

Project Overview
The Reservoir spillway structure at the International Airport required significant restoration and rehabilitation. The contractor was tasked with chemical grouting as part of this extensive project. The objective was to clean up all compromised concrete, crack inject all areas of present and past water leakage, patch it, and re-caulk all cold joints.

Identifying the Problem

Visible water infiltration and signs of efflorescence on cracks and joints were the primary concerns. Efflorescence around cracks and joints indicates past leakage, even in the absence of active water seepage at the time of inspection, and needs to be addressed.

The source of water intrusion was identified as rain runoff, which led to the oversaturation of the built-up and back-filled sections adjacent to the spillway walls.

Proposed Solution
The engineer recommended injecting the affected cracks and joints with a moisture-activated hydrophobic foam. This foam was specifically designed to address areas showing signs of efflorescence and visible water infiltration.

Execution
Custom scaffolding was erected to facilitate the repair process. The contractor’s certified crew utilized the SealBoss P2002, a portable high-pressure injection system capable of overcoming the hydrostatic and physical resistance forces within the wall, displacing moisture, and injecting the SealBoss 1510 Water Stop and Leak Seal Foam at the appropriate pressure and volume. Given that the concrete wall was approximately 12 inches thick, the SealBoss 13-100AL Evolution Packers were strategically installed by drilling directly into the cracks.

This approach was chosen based on the concrete’s quality to minimize the risk of spalling due to injection pressures. Each packer was reinjected as deemed necessary to ensure a comprehensive and durable seal. In many instances, the injected material traveled through honeycombed concrete, reaching areas several feet away from the injection point.

Whenever this happened, the injection was paused until the material reached a state of cure to ensured that subsequent injections would follow a new path of lesser resistance within the crack structure’s capillaries.

Results
The injection crew successfully halted the water intrusion well within the specified time frame. This efficiency meant that the reservoir could return to its regular levels much quicker than initially anticipated.

Note
As water may find its way to areas beyond the initial injection repair, there might be a future necessity for spot treatments in previously dry regions.

Conclusion
Efflorescence around cracks and joints, is a clear indicator of leakage, even if dry durning inspection. It often is a telltale sign of deeper structural problems.

The Reservoir project at the International Airport serves as a testament to the importance of timely intervention and the use of advanced techniques like crack injection repair. By understanding and addressing the root causes of efflorescence and water intrusion, structures can be preserved and protected for the long term.

Water Ingress in Corrugated Tunnel Sealed

The University of Leicester enlisted the services of a U.K.-based specialty repair contractor to evaluate and rectify a steel corrugated tunnel/pipe approximately 1.8 meters in diameter.

The tunnel was exhibiting signs of persistent and significant water intrusion due to damage caused by corrosion, which led to the formation of cracks and perforations at the base of the duct.

The contractor devised and implemented a solution that could be applied from the confined interior space of the tunnel. The aim was to extend the lifespan of the structure by an estimated 25 years.

Given the substantial degree of water ingress from the elevated water table, a solution was needed that would not only stop the current water flow but also provide a robust barrier against future water infiltration and leakage.

The contractor identified a proven hydrophobic, hydro-active polyurethane water stop foam resin as the most suitable solution to tackle the fractures showing severe pressing water conditions.

Sealboss 1510 Water Stop Foam, NSF certified and activated by the 15x Accelerator, was the selected chemical grout to mitigate the severe and pressing water conditions.

The advantage of using this specific waterproofing injection grout in sealing the corrugated tunnel stems from its ability to seal not only wide, gushing water leaks but also the smallest of pores and capillaries in building elements that might otherwise allow water to seep to the surface.

The low viscosity of SealBoss 1510 chemical foam grout, coupled with the specially formulated SealBoss 15X Accelerator – which can be mixed at ratios ranging from 2% to over 20% by volume with the resin – enables a range of reaction profiles. These range from slow absorption into the concrete building components, sealing all capillaries and pores, to rapid water stop high-foamer expansion for sealing larger gaps and voids.

Carefully regulated addition of the accelerator allows for controlled expansion from nearly no expansion to forty times expansion. Due to its controlled expansion, the resin will either cure to form a tough semi-flexible seal or a compression seal gasket when expanding at pressure.

Following the injection as per specification, the corrugated tunnel repair now provides a watertight seal to the concrete, effectively preventing further deterioration of the building components due to water infiltration and seasonal frost.

Dam Repair – Active Leaks Sealed

Dam Repair
Active Leaks Sealed

Addressing Dam Leakage

Several factors can play a role in the development of cracks in concrete dams. The natural shrinking of concrete, geological stresses, and inadequate soil compaction during construction all play their part. The persistent positive water pressure means that even the smallest of these cracks and fissures can become avenues for water leaks. As water continues to seep through, the cracks inevitably widen over time, potentially leading to significant water loss and a progressive deterioration of the dam structure.

Earthen dams also face the risk of significant water loss through leakage. The potential culprits are often inadequate compaction of fill dirt, faulty seams, and leaks forming underneath the dam’s breastwork. Seepage can undermine the stability of earthen dams, leading to safety concerns and operational inefficiencies.

As with most structural defects, water leaks will continue to increase until corrective action is taken.

Dam Repair – Sealing Active Leaks

Innovative injection solutions like SealBoss Water Stop Foams and Polyurethane Injection Resins have been utilized for dam repair for over three decades. Successfully used to seal leaks in both concrete and earthen dams, these materials have proven invaluable in enhancing the resilience of dams, preventing water loss, and extending the lifespan of these significant structures.

Sealing Active Leaks – Efficient Dam Repair with Water Stop Foam Injection

SealBoss 1510 Dam Leak Sealing Injection Grout has proven its efficacy at the Blue Heron Paper Mill Dam in Oregon City, Oregon. The procedure involved the use of the SealBoss SLP1C pump and Mechanical Injection Packers to deliver the grout effectively.

Addressing the considerable water infiltration from the Willamette River, the Water Stop Foam was accelerated using the highest recommended dosage of SealBoss 15X Accelerator. This resulted in the fastest setting Water Stop/High Foamer Injection System, tailored to deal swiftly and effectively with the leakage.

The procedure was meticulously executed, with injections performed at strategically chosen entry points. This approach allowed the injection team to cut off the water flow at the primary leak sources, as well as at other sites where seepage was less severe.

Prior to the initiation of the injection process, a technical sales representative from SealBoss, alongside the West Coast SealBoss sales manager, visited the site.

Pump Station Infiltration Repair

How to Stop Water Inflow & Infiltration
I & I - Repair

Texas – A Municipal Water District was experiencing heavy groundwater infiltration at the pre-cast cold joints in multiple Lift Stations in a new housing development

After previous attempts to stop an inflow and infiltration water leak using low pressure and mastic waterstop had failed, the Municipal Wastewater District reached out to SealBoss looking for a turn-key system that could withstand the hydrostatic pressures, causing active leaks in a lift pump station and seal them permanently with minimal effort, expense and resources.

Time of repair was a key factor due to the need for special permits, including a confined space permit, and lane closure requirements with traffic control for use of truck mounted equipment.

Municipal Wastewater Pump Station Infiltration Repair

With the recommendation of Chemical Grouting, following previous failures and repair attempts, the Wastewater Conveyance Team was interested in a demo of the system including an on-the-jobsite training. A SealBoss technical representative made the drive down from Kansas City to in order to demonstrate the chemical grouting system and assist the Water & Sewer Utility Provider in the installation and repair.

After arriving at the location, the leak was evaluated and a strategy for injection was formulated.

To initiate the injection plan, the first step was to drill holes in the pit. These holes were spaced approximately 12 to 18 inches apart and positioned 4 inches above the cold joint. They were drilled at a 45-degree angle, extending back into the joint. Subsequently, the holes were flushed using a squirt bottle until clean water was refused, and high-quality mechanical packers were then installed.

Following an in-depth training on the use and cleaning of the very quiet and compact SealBoss P2002-1C Injection Pump and the use of SealBoss 1510 NSF Certified Water Stop Foam, the trainee applicator climbed back in the manhole to run the pump system by himself.

To expedite the foam production process for the active leak repair, SealBoss 15X Catalyst was utilized at a slightly higher percentage than the standard recommendation of 10% volume.

The procedure involved injecting from one end of the main line pipe until resin or foam was visible at the cold joint, and subsequently spraying some water to initiate the reaction.

How to seal unexpected leaks during the injection repair

Sometimes concrete cracks and spalls form during the packer installation or injection process. Drilling holes can occasionally become to wide for the intended packer to fit. For these kinds of situations it is recommended to have Seal Oakum and various sized Injection Packers on hand.

In this specific application, as injection continued around the joint, one of the holes was apparently drilled too close to the joint and subsequently spalled out, causing it to leak significantly.

With a quick dredge of the oakum in catalyzed SealBoss 1510 Water Stop Foam, a bag of Soaked Oakum was sent down into the manhole and held in place by the applicator over the leaking spall. After about two minutes of holding the oakum in place, the leak had stopped.

The area was then injected on either side of the installed oakum to fill any remaining voids and to seal the joint permanently.

All leaks were completely stopped within 90 minutes time. The total time on site amounted to two hours.

Wet Basement Leak Sealing with Injection System

Do You have Water Leaks in Your Basement?

Prevent mold development and other problems from occurring by using the SealBoss polyurethane foam injection system to seal cracks and joints in your basement walls and foundation.

A damp and leaky basement not only emits an unpleasant odor but also threatens to reduce the value and livability of your home. Moisture in the basement creates an ideal environment for mold growth and can contribute to the deterioration of foundations, walls, and floors.

Neglecting to seal cracks and joints can have severe consequences as it enables water to penetrate the structure, propelled by both hydrostatic pressure and capillary action. Capillary action is the phenomenon of water being pulled up through a substrate by cohesive and adhesive forces. Water that rises through capillary action also transports minerals and salts, which can contribute to greater degradation of the structure. It’s crucial to address and seal any cracks and joints in order to prevent these harmful effects from taking hold.

The SealBoss polyurethane foam injection system is an effective and reliable solution to repair water leaks in basements.

One of the main advantages of using the SealBoss system is its ability to penetrate and fill even the smallest cracks and voids in the concrete, effectively sealing off any potential water intrusion points.

The SealBoss system is a non-invasive solution, meaning that it does not require any major excavation or demolition work. This makes it a cost-effective and time-efficient solution, with minimal disruption to the homeowner’s daily routine.

Furthermore, the SealBoss wet basement solutions system provides a permanent solution to the problem, unlike temporary solutions such as surface sealants and waterproofing paints. The foam is resistant to water, mold, and mildew, providing long-lasting protection against future water leaks and moisture-related problems.

Overall, the SealBoss polyurethane foam injection system is an effective, non-invasive, and long-lasting solution to repair water leaks in basements, providing homeowners with peace of mind and protection against potential water damage.

Residential Wet Basement Solutions – Polyurethane Injection

Sealing Basement Leaks with Polyurethane Foam Injection System

Scope

A SealBoss-certified contractor based in St. Louis was requested to repair actively leaking basement cracks in a residential property during heavy rainfall.

Wet Basement Solution – Detail

Based on a comprehensive inspection and assessment of the jobsite and considering the width of the crack, it was concluded that drilling a hole directly over the crack at a 90 degree angle and all the way through the wall would be necessary.

This method was considered the most effective way to permanently seal the crack. It involved a combination of crack injection and curtain injection procedures. The injection process allowed for the product to flow from the dirt side of the structure, which is known as the positive side, back through the crack to the inside of the structure, while sealing the crack completely.

The injection on the blind side resulted in a buildup of the hydrophobic resin, creating a curtain on the positive side of the wall. The injection process created a barrier, which subsequently caused the pressure buildup to push the resin back into the crack itself. This sealing process effectively sealed the crack and any fissures present in the process.

Materials and Tools Used

The preferred products for the job were SealBoss 1510 and SealBoss 15X Accelerator. To speed up the reaction, the SealBoss 15X accelerator/catalyst was incorporated into the resin at a volume ratio of 10%.

Injection packers were set along the crack, roughly twelve inches apart.

The injection process utilized the P2002 compact high pressure injection pump along with Evolution 13-100AL ½” packers to inject the polyurethane foam resin.

A quantity of approximately one gallon of material was utilized for each six lineal feet of the crack.
