SealBoss 1510 Leak Sealing Application

What is the Purpose of a Spillway in Dams?

A spillway serves a critical function in dam systems. Either incorporated into the dam’s structure or built adjacent to it, a spillway facilitates the controlled and secure discharge of surplus water downstream.

SB 1510 Polyurethane Foam in Dam and Spillway Leak Sealing: An Overview

Polyurethane foam, known for its superior adhesive properties and low viscosity, plays a pivotal role in sealing leaks in dams and spillways.

Its unique characteristics, superior adhesive properties and low viscosity, make polyurethane foam an optimal choice for addressing expansive cracks, joints, and gaps in concrete structures. Hydro-active foam penetrates deeply into these openings and crevices, efficiently arresting active and high-velocity water flow, while also filling the cavities to form a waterproof seal that impedes future water seepage.

The remediation process initiates by drilling holes around the leak-prone area within the concrete perimeter. Following this, specialized injection equipment introduces polyurethane foam through the installed injection packers in the drilled holes. Upon injection, the foam expands and fills the concrete voids, establishing a sturdy bond with the surrounding substrate. After curing, the foam evolves into a solid and durable repair, effectively sealing the water leak in the spillway. Polyurethane water stop foam injection offers an effective and economical solution for many dam spillway leak repairs.

Sealing Dam Spillway Leaks with 1510 Water Stop Foam: A Case Study

How to Seal a Dam Spillway Leaks with Hydro-Active Polymer Injection

SealBoss was enlisted to tackle the problem of leaking Cold Joints, a situation that had resisted repair through four prior methods. The caulking previously deployed to seal the joint had been compromised, leading to water erosion and diminished adhesion between the caulking and the concrete. As a result, water was infiltrating through the “V” notched joint at an increasingly concerning rate.

Preparation and Injection Procedure

The repair endeavors focused on sections with active water leaks – characterized by high velocity and volume – visible efflorescence, and loose caulking. Caulking removal was required to expose the cold joint.

In preparation for placing the mechanical packers, the contractor drilled holes. When water began flowing from these holes, it was clear the drill bit had successfully intercepted the joint.

At times, it may be beneficial to keep a drill hole unsealed initially, delaying the installation of the injection packer. This approach can serve as a pressure relief point, helping to alleviate hydrostatic pressure and regulate water flow.

In preparation for the injection procedure and to curb water flow, the Oakum Soakum Technique was employed to address the gushing leaks first. SealBoss 1500 Seal Oakum, soaked in SealBoss 1510 Water Stop Foam catalyzed with a significant amount of SealBoss 15x Accelerator for quick setting and curing, was inserted into the actively leaking crevices and held in place until cured.

After completing the oakum patching process, the next phase involved installing the injection packers. The 13-100 AL packers were set in place following the 1, 2, 3, 45 Degree Injection Guidelines, with a 14″ staggered vertical spacing and about 7″ on either side of the joint to avoid interfering with the rebar.

The injection procedure commenced from the lowest packer, using SealBoss P2002 pumping equipment to inject the catalyzed SealBoss 1510 Water Stop Foam. We suggest occasional injection pauses to let the resin expand and to reduce product wastage.

Success – Dam Spillway Leak Sealed

Through these measures, all the joints were successfully sealed, and active leaks were effectively addressed.

Conclusion

In summary, the usage of polyurethane foam, particularly SealBoss 1510 Water Stop Foam, has proven to be an effective and economical solution for dam and spillway leak sealing.

The method’s success lies in the foam’s ability to penetrate deep into the crevices and gaps, providing a robust, waterproof seal.

The above case study underscores how a strategic, methodical approach can result in successful sealing of active leaks, reaffirming the significance of this solution in the field of dam and spillway maintenance and repair. As we look forward, we can anticipate that such techniques will continue to evolve, further enhancing the efficiency and effectiveness of leak repair in dam spillways.

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.

Curtain Injection In Pictures

Curtain / Bladder Injection - Curtain Wall Grouting Method

The Reliable Way to Waterproof Your Below Grade Concrete Structure Permanently – Why Patches and Liquid Sealers Often Don’t Stand the Test of Time

Experiencing the frustration of failing patches and paint applications on damp, actively leaking, below-grade structures is something many of us can relate to.

These are typically failed attempts to block hydrostatic water intrusion using surface-applied remedies that serve as temporary solutions at best.

Interior patches and membrane applications, while seemingly addressing the problem, often don’t tackle the root cause and rarely provide a lasting waterproofing resolution.

A Professional Approach to Curtain Injection:

Sealing Cracks Permanently and Establishing a Waterproof Membrane and Water Barrier behind the Structure

Water leakage via cold joints, cracks, and other irregularities in concrete can frequently only be effectively and permanently sealed using advanced injection techniques, such as curtain, bladder, and stage grouting injection methods.

The SealBoss Injection Product offers a professional solution to these issues, filling and sealing the cracks from the inside out. This product is injected through the structure, forming a membrane on the structure’s positive side, thus providing a more effective and lasting waterproofing solution.

The Art of Stage Grouting Technique

In complex grouting scenarios, the stage grouting technique is often the favored approach. This process entails a strategic series of injections carried out in a staged manner, utilizing lower volumes of product in each application.

Each stage of this meticulous process is allowed sufficient time to react, allowing the grout to solidify and establish a natural barrier before proceeding with the subsequent stage of grouting. This carefully phased and controlled deployment not only elevates the overall efficacy of the grouting operation but also ensures thorough and consistent coverage along the exterior of the wall.

Comparative Cost Analysis of Injection Grouting Sealing Methods

Understanding the financial impact of various sealing techniques is essential for making cost-effective decisions. Below is a comparison.

Crack Injection

Direct Costs: Moderate for materials and labor, product is injected directly into the cracks, joints, and voids. Low for equipment.
Indirect Costs: Minimal, as the method is fastest and causes little service interruption.

Curtain Grouting

Direct Costs: Higher for materials and labor, product is injected through the structure into the substrate behind, which results in higher material consumption. Packers are set in distinctive patterns. Moderate for equipment.
Indirect Costs: Higher, due to the lengthier process of preparation and product pumping, which can lead to more significant service disruptions.

Hollow Core Concrete Slab Water Leak Repair

Hollow Core Concrete Slab Injection

What is a Hollow Core Slab ?

A hollow core concrete slab, also known as a hollow core slab, is a precast slab of prestressed concrete, typically used in the construction of floors in multi-story buildings and parking structures

Parking Garage Repair with SealBoss 1510 Foam Injection

The Problem

The client was experiencing water intrusion through hollow core concrete slabs and along exterior wall and sill plate cold joints in below parking garage causing water to drip onto cars and creating unsightly watermarks on the walls.

A waterproofing contractor was asked to seal the cold joints and cracks in the affected hollow core concrete slabs, and to determine and stop the source of leakage.

The Solution

To address the issue of the leaking hollow core slab, the contractor reached out to the SealBoss Regional Sales Manager to advise on the injection of the hollow core slab.

With a quick walk around the exterior, it was made clear that there were drainage issues where the downspouts fed the run-off onto a grassy area with no sloping to direct the water away from the building.

Once the source of the leak had been determined, a two-step injection strategy was adopted as the best solution. The initial injection was to inject cracks in the hollow core slab where water was leaking out and dripping onto vehicles. The subsequent injection would be to seal off the end caps of the hollow core cells where the leak originated.

Once the contractor began to drill holes for the injection packers, water poured out and it was obvious that the hollow core was completely filled with water. After the water was drained the crack was injected and sealed.

To verify that water had not traveled between cells, weep holes were drilled into the adjacent cells. Water was found to have also filled another cell of the hollow core and had to be drained.

Using a borescope, it was confirmed that there was water intrusion where the hollow core had been capped off with a plastic cap (see video below).

The weep holes were left open to prove that the leak had subsided.

The client was advised to add drainage boxes to help direct flow away from the building in areas where water pooled and to notify contractor of any new leaks this upcoming spring when the ground will thaw.

SealBoss 1510 NSF/ANSI 61 Water Stop Foam was injected into the exterior cold joint along the areas where water intrusion was visible from efflorescence or rust stains. All visible leaks were addressed using the 1, 2, 3, 45 Degree method via injection packers that were placed roughly 12” from the joint where ½” holes were drilled at a 45-degree angle back into the joint. 1510 was injected until positive refusal of the hydro-active resin was visible along the cold joint.

All affected cells of the hollow core concrete slabs were injected approximately 6” from the end cap and sealed off using SealBoss 1510 NSF/ANSI 61 Water Stop Injection Foam System.

How to Permanently Waterproof Tilt-Up Panel Joints with Polyurethane Grout

Failing and leaking tilt-up construction joints can be sealed to full depth with single component SealBoss 1570 NSF Certified Water Stop Foam and the Oakum-Soakum Method

Tilt-up Construction Joints are Typically Caulked

Over time, caulks often fail, break open, and allow water to flow into the structure. Caulk failure can be evident as shrinkage of the bead of sealant, delamination (caulk no longer sticks to surface), cracking of the bead, powdering or dusting of the surface of the caulking.

How to Create a New Full-Depth Joint Seal

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.

What is SealBoss ® Can Seal Foam?

Can Seal Foam is a versatile, closed cell, self curing foam for universal uses. The product is a single component MDI based polyurethane of highest quality. It expands, bonds and seals while stopping the passage of air, gases, water and dust. Besides its obvious uses to stop water infiltration it can increase energy efficiency by stopping air exchange around windows, doors, wall intrusions and at sill plates. Its lightweight, closed cell structure makes it useful for deadening sound, flotation and thermal insulation. It is also useful for scaling work areas prior to stripping to prevent the transport of fibers. SealBoss  Can Seal Foam is very efficient, you get up to eight gallons foam just from one can!

The Important SealBoss Difference

SealBoss ® Can Seal Foam is specially formulated to fully expand inside the applicator ‘gun barrel’. When the foam exits the tip of the gun it is almost fully expanded – you apply exactly as much foam as you need without the messy and undesired “mushrooming” experience you may have with most of the other ‘over the counter’ foam products. This feature makes our foam predictable and suitable for many applications that cannot be performed with standard foam products. And with the  professional applicator gun you can fill voids with the exact amount of foam desired.

Contractors use our foam for many applications such as water-stop purposes in voids and cable runs, as an insulation and seal-foam in general construction and as an instant ‘Backer Rod Bead’ in applications where joints need a back fill prior to applying the final sealant.
