Cold Joint Injection

Leaking Cold Joints Sealed

Cold Joints in Concrete and the Polyurethane Polymer Solution

Introduction

Concrete is a versatile and durable construction material, but like all materials, it has its weaknesses. One such weaknesses is the formation of cold joints. Understanding what cold joints are and how to address them is crucial for anyone involved in the construction or repair of concrete structures.

What are Cold Joints?

A cold joint forms when newly mixed concrete is laid adjacent to or over concrete that’s already started to harden. This situation can manifest due to several factors, including disruptions during pouring or delays in the mixing and transportation of the concrete. This leads to the formation of a distinct boundary, a zone lacking cohesion, where the previously set and fresh concrete converge. Such a boundary weakens the overall structural strength of the concrete, rendering it susceptible to water infiltration and potential leakage. Over time, the presence of cold joints can reduce the overall lifespan of the concrete structure.

The Polyurethane Polymer Foam Injection Solution – Injecting cold joints with polyurethane polymers has emerged as an effective solution to address the issues of water migration and leakage.

Injection Process

Using specialized equipment, the polyurethane polymer is injected into the cold joint. The polymer fills the voids and gaps, creating a permanent seal. The polymer acts as a barrier, preventing water from seeping through the cold joint. The injected polymer reinforces the cold joint, reducing the risk of corrosion, cracks or breaks. With the cold joint addressed, the overall lifespan of the concrete structure can be significantly extended.

Addressing Cold Joints with the SealBoss Injection System – Comprehensive Solution to Moisture and Active Leaks

Cold Joints are common locations where moisture and active leaks are frequently observed. Whether stemming from a flawed waterproofing system or its total absence, we offer a comprehensive solution to address the leak and stop any water intrusion.

Our SealBoss Regional Sales Manager was on-site in Kansas City to train and assist with the injection of below grade cold joints that had begun to actively leak due to failures in the pre-existing waterproofing system.

Both vertical and horizontal cold joints were injected with various levels of leak activity. The contractor drilled the injection holes and installed 1/2″ SealBoss mechanical packers for a tight fit. Based on the conditions the 45 angle drill degree method was used as well a direct into the joint placement was chosen.

The applicator then injected SealBoss 1510 using the P2002 high-pressure single component injection pump. Due to the relatively low temperatures of the substrate the product was catalyzed with approximately 15% of SealBoss 15X highfoamer accelerator. All active leaks were successfully stopped and the Cold Joints sealed.

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.

Why Do Seawalls Fail? Causes and Repair

Why do Seawalls Fail?
Causes and Repair

Commercial and Residential Seawalls

An Overview

Why do Seawalls Fail? – Causes and Repair:

Inadequate maintenance and inspections
Soil erosion and overloading the soil behind the seawall
Building too close to the wall
Altering water flow or trapping water behind the seawall
Using materials unsuitable for marine conditions.
Corrosion from marine or otherwise damp environments, especially on concrete and steel rebar
Property changes, like adding pools or buildings, that add unexpected weight
Severe weather events that strain the seawall

Keep the Integrity of the Seawall Intact, and Avoid Erosion Inside, Under, and Behind the Seawall

Erosion is the main cause for seawall failure. Leaks within the wall, caused by cracks and failing joints, insufficient drainage of water runoff from the land-side, and other construction related problems, such as improper soil compaction, will contribute to premature and accelerating erosion, undermining the integrity and viability of the seawall.

Seawall Inspections

Frequent seawall inspections, especially after a heavy rainstorm or major storm, can help owners to early on recognize problems with their seawall, and perform seawall repairs in a timely, affordable and effective fashion. The key is to reduce or eliminate erosion in it’s early stages.

Seawall replacement is a costly construction project and most likely highly disruptive to the owner and the environment. Seawall construction could mean expensive and lengthy permitting processes, lasting weeks or months.

Maintaining Your Seawall

Every wave and tidal cycle provides a stress situation for a seawall structure, no matter how well constructed. As soil washes away, voids and gaps may form, in or under the wall. As a result, the footer may no longer supported by a solid foundation, leading to cracking of the wall and failing wall joints.

If the obvious need for seawall repair is ignored, the process of decay will continue and accelerate, potentially creating major hazards to people and the environment. Sinkholes are forming and the ground is caving in behind the wall, affecting nearby structures, including walkways and sidewalks, patios and pool deck slabs.

Seawalls, Seawall Footers and Bulkheads can be Repaired with Polyurethane Chemical Grouts and Epoxies

We provide the products and systems to stop water, fill voids, seal leaks, repair cracks, and stabilize loose soil for your seawall repair. Extend the service life of your seawall for years to come and at a fraction of the cost of replacement.

Seawall Repair Methods

Commercial and Residential Seawalls

Seawalls serve as guardians of our coastlines, protecting from the ocean’s force, while also shielding properties by bays, rivers, and lakes. Yet, their resilience is tested by the ceaseless tides and natural elements, resulting in wear over time.

Introduction:
Seawall Failures and Effective Seawall Repair Strategies

Over the passage of time, even the sturdiest seawalls can exhibit cracks, becoming susceptible to water penetration. In certain scenarios, the very foundation of the seawall might shift due to the erosion of its supporting substrate. Proactively identifying and rectifying these concerns can stave off escalated damage, ensuring the seawall remains a steadfast defense against water and erosion.

Whether for private residences or commercial establishments, many seawalls are crafted with similar design principles. Their upkeep and restoration can be effectively managed using hydro-active, hydrophobic polyurethane foams for leak-sealing and water-stopping, as well as two-component or dual-component polyurethane foams for void-filling and elevation.

When it comes to repairing structural concrete damages and concrete spalls in seawalls and marine piles, epoxy injection resins can be a reliable option. These resins can provide long-lasting reinforcement to the affected area, helping to ensure that the seawall or pile can continue to withstand the stress and impact of waves and tides.

Understanding why seawall failure occurs and taking timely steps to prevent further damages is important to protect your land and any structures that may be impacted by ingress of water and shifting soils.

Why Do Seawalls Fail?
Causes & Warning Signs of Seawall Failure

Poor Maintenance | Lack of Inspection to Detect Problems Early
Erosion, Washout, Sinkholes
Footing, Bulkhead Shift Due to Erosion
Cracks and Expanding Cracks in Seawall
Rust & Corroded Rebar Expansion
Drain Failure
Environmental Factors – Natural Disasters

Regular and Proactive Inspections and Maintenance: A Key Strategy to Prevent Seawall Damage

Executing frequent inspections and prompt maintenance are integral to extending the lifespan of your seawall. These preventative measures can save you from costly repairs in the long run by addressing potential issues before they escalate.

A significant issue you may encounter is the clogging of drain and weep holes. These are crucial components in the seawall’s design as they allow water accumulated behind the wall to drain. If clogged, water will build up, leading to added stress on the seawall and potential damage. This accumulation of water can soften and loosen the soil behind the wall, which could increase pressure and raise the water table. Such conditions might result in the formation of cracks in the seawall structure, thus creating new, unintended pathways for water flow and consequently causing soil erosion.

Understanding the Implications of Soil Erosion due to Accumulated Damages

Water migration through these new pathways, cracks, voids, and defects can lead to a gradual weakening of the seawall. As the wall undergoes consistent damage and erosion, its foundation may lose support and shift. This can be particularly problematic because soil erosion has the potential to create sinkholes. These sinkholes can further collect water, accelerating the decay process and potentially leading to the seawall’s failure.

Hence, regular inspection and maintenance can help identify early signs of soil erosion and structural damages, thereby preventing severe consequences and ensuring the longevity of your seawall.

Location: Granite Boat Chute, Arkansas River, Colorado

Objective: To Seal Leaks and Repair Cracks in Seawall Grout Cold Joints

Cold joint and crack injection of grout joints in Natural Boulder, Rock, Stone, River Seawall

SealBoss 1510 Water Stop Foam – NSF Listed and Drinking Water System Component Approved injection System

Along the beautiful and pristine Arkansas river is the Granite Boat Chute. For the first time in more than half a century, rafters and boaters can float the Arkansas River from Leadville to Cañon City without disruption.

During a repair last season on the divider seawall and re-installation of a section of the boulder wall a cementitious grout was used to bond boulders together and to bond to existing boulders and existing grout. Over time some of the cold joints between the old grout and new grout started leaking. Leaks also developed at bond failures between the natural boulders and rocks, and the cementitious grout. Hairline cracks also developed to contribute to water seepage.

SealBoss 1510 NSF hydro active foam, an environmentally friendly product with NSF drinking water contact certification, was injected into the areas of bond failure to seal the boulder seawall from water intrusion and to prevent future water induced issues with freeze / thaw cycles that contribute to further damages and eventually could lead to blowing out the seawall.

Spacing of the packers was at an interval of 12” and the catalyst was initially at a 5% by volume to allow for travel down in to the areas between the stone to ensure a proper seal throughout the conglomeration. Later the accelerator was increased to a 10% by volume to 1510 to foster a more rapid reaction and cure to fill in some of the remaining voids.

In conclusion, this project outlines innovative solutions that can be employed to address natural wear and erosion challenges.

The use of SealBoss 1510 NSF hydro active foam showcases the potential of polyurethane foam technology in ensuring the longevity and safety of such structures. By addressing the cold joints, bond failures, and hairline cracks, the SealBoss system not only rectified the immediate issues but also fortified the seawall against future damages.

NSF Drinking Water Contact Foam

SealBoss 1570 Water Stop Foam, combined with SealBoss 15x Accelerator, constitutes a hydrophobic water-activated and hydroactive grout solution. This innovative blend serves as a water cut-off and foam seal grout, grounded in MDI polyurethane technology. Notably, this resin boasts a solvent-free formulation and is entirely composed of 100% solids.

Today I like to talk our “Flexible Injection Foam Grout For Moving Structures” – SealBoss 1570

Let us discuss how SealBoss 1570 Flexible Foam is different from our flagship versatile chemical grout SealBoss 1510.

The highlight of SealBoss 1570 are the outstanding elongation and compression properties which make it a very flexible product with a bounce back performance similar to a memory foam.

SealBoss 1570 is the product of choice for environments where you expect oscillation, vibration, movement and compression.

1570 flexible water stop foam uses the standard accelerator SealBoss 15X and the liquid properties and reactive features are similar to SealBoss 1510 which make switching between products very easy and convenient.

SealBoss 15x Accelerator is a powerful additive for the SealBoss Hydrophobic Injection Foam Line.

By adding accelerator at varying ratios you can change reaction time and behavior of each foam to precisely suit your needs. With a little accelerator ‘magic’ you can shut down gushing leaks, seal hairline cracks and perform soil stabilization with the same product.

15x accelerator spans all three of our base resins the 1510 Water Stop Foam, the 1570 Flexible Leak-Seal Foam and a 1570 LV Low Viscosity Crack Injection Foam. 15X Accelerator can be used in a wide range by volume in a percentage anywhere between 2% and 20%.

15x Accelerator - the little star that does a lot.
