Polyurethane Water Tank Sealants for Water Treatment Plants

Polyurethane injection chemical grouts serve as versatile and adaptable sealants, capable of effectively sealing cracks even in less than ideal conditions. These grouts can be employed to seal both narrow and wide cracks, as well as dry and actively leaking ones, and those containing contaminants such as mud or mineral deposits.

SealBoss low-viscosity, hydro-active, expanding polyurethane injection resins and chemical grouts provide exceptional penetration and adhesion properties when applied to wet or dry cracks, ensuring a robust and lasting seal.

In large concrete structures, cracks can emerge anytime after the pore and cure process, particularly in structures with extensive surface areas. As such, it is not unusual for cracks to require sealing during the construction phase. Furthermore, water leaks often manifest within the first five years of a structure’s life.

Water Treatment Plants are designed with strict specifications that necessitate minimal water migration, leakage, inflow, and infiltration. Failure to address water tank leakage properly and promptly can result in an increased risk of subsequent damage, including reinforcement and concrete corrosion.

For over three decades, Water Treatment Plants have effectively utilized SealBoss polyurethane water tank sealants to address and resolve water leak issues in their concrete structures, ensuring the integrity and longevity of these vital facilities.

Injecting Cracks Exhibiting Water Intrusion Prior to Seal Test

Jobsite Overview

A newly constructed tank at a Water Treatment Plant in the mid-west necessitated the sealing of its cracks using a specialized polyurethane water tank sealant system.

A SealBoss technical expert was called upon to provide on-site guidance for the injection procedure and to assist SealBoss Certified Installers in formulating a plan for a cold weather injection.

Inspection Process

After going over safety procedures, and following safety protocol, a three-person crew entered the tank to examine the leaks. They identified two overhead cracks with active, slow-moving leaks, manifesting as drips.

Water Tank Sealant System Implementation

The objective of this injection process was to inject NSF/ANSI 61 certified SealBoss 1510 Water Stop Foam into the leaking cracks within a non-permit confined space. The SealBoss Injection System, featuring Evolution 13-100 AL injection packers and the P2002 ultra-portable injection pump, was utilized for this purpose.

During the injection packers’ installation, some drill holes began to leak, indicating successful intersection with the crack for packer placement. Once the injection ports were secured, warm water was injected through each packer to facilitate catalyzation and accelerate the reaction. Next, the 1510 Water Stop Foam and 15x Accelerator were mixed in the P2002’s hopper, and the injection of the 1510 sealant into the water tank began.

Shortly after initiating the injection, the resin started displacing the water within the structure’s voids, causing water and gas to escape from the crack’s face. Injection continued until resin was observed emerging from the crack.

Each port was injected in a similar manner, adhering to the 1, 2, 3, 45 Degree Injection Guidelines. After the crack was completely injected and cured foam visibly flowed from the crack’s face, each packer was re-injected.

If immediate pressure buildup occurs, it indicates that the crack has been effectively sealed. If pressure does not build up instantly, the crack requires low-pressure reinjection to enable the resin to further penetrate the crack and displace any remaining water, ensuring a comprehensive and efficient seal.

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.

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.

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.

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.
