Municipal Wastewater Pump Station Infiltration Repair

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

Municipal Wastewater Lift Pump Station Inflow & Infiltration (I&I) Repair- SealBoss 3

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.

Historical Building Repair – PUR Injection

This well over a century old historical apartment building had persistent water intrusion through the masonry rock foundation into the below grade parking garage.

A SealBoss Technician was asked to come out and consult with a local installer in St. Louis, Missouri, to find solutions for the water ingress problem. The majority of the exterior walls where the sill plate sits at or just below grade had shows signs equivalent to years of water intrusion.

The century old stone wall, and the grout holding the natural rocks in place, had become compromised. Water would seep from the soil through the wall causing further decay, unsightly stains and in some areas growth of unsightly algae.

Previous non-permanent and haphazard repairs included cleaning the wall and opening up the face with a grinder then applying a cementitious grout over the whole face of the wall. This attempt of a repair would fail within a year of application.

The approach to a permanent historical building repair was to inject any visible cracks first. One of the areas with heavy water intrusion was a doorway that lead from the parking garage to the stairs leading to the domicile. Here there was a water bearing crack with an active leak overhead as well as a cold joint between the floor and stub wall.

The overhead crack was addressed using  5/8” Plastic Injection Ports as the grout lines would crack and flake when a mechanical packer was tried initially. A zerk tip was added to the injection port and the crack was primed by injecting water through the packer till positive refusal was seen from the crack.

SealBoss 1510 Chemical Injection Grout was then injected under pressure to displace any water in the crack and began to cure and seal the area.

To address the cold joint on the floor in the stairwell, ½” packers were installed on the floor roughly one foot apart and six inches from the wall. It was confirmed that behind the stub wall in the stairwell was substrate and upon install of the Packers, it was found that the floor had only been about a two inch pour.

With the thin floor slab, it was advised to inject through the slab creating a “blanket” of 1510 below the slab since the slab thickness would not allow for the standard 1, 2, 3, 45 Degree Injection Packer Placement Method.

A weep hole was also drilled in the slab to allow for a controlled point where the water and off gas could be directed. Positive refusal of the foam was visible from the cold joint, and once the joint had been sealed, packers were removed and a hydraulic cement patch was installed.

Once all cracks have been addressed, wet areas can be addressed by curtain / bladder injection, where chemical grout is injected behind the wall to create a waterproofing barrier between the soil and the wall on the positive side of the structure.

Private Road Repair Using SealBoss 6060 QuickFix

On The Job

Private Road Repair | SealBoss 6060 QuickFix Fast Setting Polyurethane

SealBoss Technical Rep On the Road

Roads can crack and settle over time from a multitude of environmental factors.

If your street is a private road, the city is not responsible for the repair or maintenance and that responsibility falls on the residents of that private development.

Having a quick and efficient way to do these repairs when they come up is key, while still being able to respect the resident’s privacy with minimal disruptions.

SealBoss 6060 Spall & Crack Repair QuickFix is a self-leveling repair material to which sand can be added for strength, anti skid properties and aesthetics.

SeaBoss 6060 takes only about five minutes to fully cure at ambient room temperature. The product cures in temperatures down to -20 degrees Fahrenheit. Lower temperatures will increase cure times.

To prep surface cracks for the repair a V-notch blade should be used to chase the cracks and then thoroughly cleaned out of small rocks and any other debris and organic matter. For best results the cracks must be dry — if moisture is present a propane torch may be used to dry the area.

Once crack is prepped and the material is conditioned, you can begin applying SealBoss 6060 QuickFix to the crack. After about a minute you can then broadcast sand into the curing material.

Doing this allows for a non-slip surface as well as a salt and pepper finish to help blend the repair.

SealBoss 6060 QuickFix is available in 22oz cartridges (see pictures below) as well as in bulk in pails, drums and totes.  The SealBoss Road Repair System is shown here to repair concrete road cracks. 

The SealBoss JointMaster 2 G3i Joint Fill Pump (see picture below in the background) is the recommended equipment for larger applications and potholes and repairs of blacktop / asphalt / bitumen finished roads.

Concrete Raising / Foam Jacking

Poly Jacking and Foam Jacking – Lifting Concrete Slabs with Plural Component Foam by SealBoss

Introduction

The innovative technique of Poly Jacking, also known as Foam Jacking, is rapidly gaining recognition.

This method, utilizing plural component structural polyurethane foams, offers a clean and quick solution for stabilizing and lifting sunken concrete slabs. This overview explains some nuances of this process, exploring its phases, methodologies, and the expertise SealBoss brings to the table.

What is Poly Jacking / Foam Jacking?

Poly Jacking, or Foam Jacking, is a specialized process designed to repair sunken and unstable concrete slabs. The technique involves injecting SealBoss 1640 Structural Strength Slab Lifting, Polyjacking, and Void Filling Foam beneath the concrete. This is achieved by drilling small holes and pumping the expansive foam under the slab, providing support and elevation.

The Inspection Phase

Evaluating the Site

Before commencing the Poly Jacking process, a thorough inspection of the slab lifting area is essential. This includes:

  • Soil Condition Assessment: 
    Understanding soil conditions is vital, as discussed in our article,  What Is Dynamic Cone Penetration Testing | SealBoss Deep-Soil-Lift

  • Structural Damage Analysis:
    Identifying any structural damages to the concrete and the extent of support loss due to voids or cavities beneath is crucial

  • Measurement of Sunken Slabs:
    Structural damages to the concrete slab and loss in support (voids/cavities) under the structure need to be determined. The actual loss in height of the sunken slabs of concrete have to be measured.

These factors collectively aid in predicting the success of the repair and determining the necessary materials and time.

The Repair Phase

Strategy and Execution

Prior to lifting a sunken piece of concrete slab the method of approach has to be determined to achieve the desired result.

The points of initial and subsequent injection and sequence of injection is crucial to lift a slab evenly and with the least stress to the concrete as possible, as concrete sections may crack. Even distribution of pressure during the process is key to lift a slab successfully.

When SealBoss polyjacking grout is first injected through drill hole in the slab it will initially fill any voids and cavities under the structure.

Once the voids are filled and the foam grout has gained strength, it will start to build pressure and compact the soil under the slab to the point where the soil is dense enough to support the foam pressure necessary for the slab to lift. Soil of lower density will compact more under pressure and may require more foam grout during the process.

As the pressure builds and the lifting process begins, the vertical movement of the slab has to be monitored closely. The points of injection may need to be alternated to keep forces and stresses to the slab as low as possible and to prevent cracks in the concrete. Even and steady lifting is the key to success.

During the lifting process the soil will continue to compact until reaching sufficient density to raise the slab to the desired elevation and level with the surrounding substrate.

Execution Steps Overview

  • Determining the Approach:
    Before lifting the sunken slab, an appropriate method must be planned to ensure the desired outcome

  • Injection Point and Sequence:
    The choice of initial and subsequent injection points and their sequence is critical to evenly lift the slab and minimize stress and potential cracking

  • Void Filling and Strength Building:
    Initially, SealBoss polyjacking grout fills voids and cavities, gaining strength to build pressure for lifting

  • Soil Compaction and Slab Elevation:
    The foam grout compacts the underlying soil, enhancing its density to support the lifting process

  • Monitoring and Adjusting:
    Continuous monitoring and adjusting injection points are essential to ensure even lifting and prevent concrete cracking

  • Achieving Desired Elevation:
    The process continues until the slab is raised to the desired level, aligning with the surrounding surface

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.

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.
