Water Treatment Plant Tanks Sealed

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.

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 Solutions

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.

While caulking creates a small 1/4″ to 1/2″ bond surface with the concrete panel, 1570 Polyurethane Leak Sealing Resin soaked SealBoss Seal-Oakum fibre provides a full-depth bond and seal against leaks permanently. The ‘Oakum Soakum Technique’ is a proven methodology for polyurethane chemical grout installation — creating a permanent seal that remains unaffected by wet, dry, and even in constant water submerged environments.

How to Prepare the Joint

Prior to any remedial repair, the existing, failed caulk has to be removed, and the joint needs to be free of any debris. The joint then needs to be wetted for the water activated grout to react, expand, and cure.

How to Install the Flexible Permanent Seal

To create a permanent seal with the Oakum-Soakum Technique, oakum fibres are first soaked in hydro-active 1570 polyurethane resin (catalyzed with SealBoss 15X Accelerator), and then pushed deep into the clean and pre-wetted joints to form a flexible and uniform seal during expansion.

How to Protect and Finish the Seal for Cosmetic Appearance

After the foam has cured, any surplus of the foam/oakum seal is cut back and finished with an even bead of caulk to provide UV resistance and achieve a matching surface appearance to the other caulked joints.
