Understanding PU Chemical Grouting Waterproofing

PU chemical grouting is a specialized waterproofing technique where polyurethane resins are injected into cracks, joints and voids in concrete and masonry structures. These resins expand when injected, filling gaps and cracks and then cure to form a durable, water-tight seal that prevents further water ingress. The expansion of the resin ensures that the grout fills even the smallest voids, offering a robust and flexible solution that adapts to the movement of the structure.

One of the primary benefits of PU chemical grouting is its ability to maintain flexibility even after curing, which allows it to accommodate structural movements such as temperature changes, ground settling and other dynamic forces that can affect the structure over time. This makes PU grouting an ideal solution for a wide range of applications in Chennai, including waterproofing basements, water tanks, lift pits, tunnels and other critical structures.

Specifications of PU Chemical Grouting Products

PU Chemical Grouting Products are known for their exceptional performance in sealing cracks and preventing water ingress. The key specifications include:

Rapid Expansion Rate: The PU resin expands quickly, filling micro and macro voids thoroughly and completely.

Low Viscosity: The resin has a low viscosity, allowing it to penetrate fine cracks as narrow as <0.1mm, ensuring effective sealing.

Excellent Adhesion: The resin bonds strongly to concrete and masonry surfaces, creating a durable seal that withstands water pressure and environmental stress.

Flexible Cured Resin: After curing, the resin remains flexible, allowing it to accommodate structural movement without losing its waterproofing properties.

Resistance to Water, Chemicals and Microbial Attack: The PU resin is resistant to water pressure, chemicals and microbial growth, making it ideal for challenging environments like water tanks and underground structures.

Compliance with Industry Standards: The products comply with ASTM C881 and EN 1504-5 standards, ensuring high-quality results.

Applications of PU Chemical Grouting

PU chemical grouting is a versatile solution that can be applied across a variety of construction environments. Below are the key applications where EMERGE INFRA excels in delivering top-quality waterproofing services:

Sealing Active and Dormant Leaks in Basements and Underground Structures
Basements and underground structures are vulnerable to water seepage, which can lead to mold, damage to the foundation and other long-term issues. PU grouting effectively seals both active leaks (where water is currently entering) and dormant leaks (previously sealed cracks that have re-opened).

Waterproofing Lift Pits and Elevator Shafts
Elevator shafts and lift pits are prone to water damage due to their location and constant exposure to moisture. Our PU chemical grouting services are ideal for sealing cracks and joints in these areas, providing long-lasting waterproofing that protects both the structure and the equipment.

Crack Repair in Tunnels, Dams and Water Tanks
Tunnels, dams and water tanks are vital infrastructure components that often suffer from cracks and water leakage. PU grouting is highly effective for repairing cracks and sealing leaks in these structures, ensuring the prevention of further damage and loss of water integrity.

Ground Stabilization and Void Filling Under Slabs and Foundations
In some cases, ground instability or voids under slabs and foundations can lead to structural settling or movement. PU grouting fills these voids, stabilizing the ground beneath the slab or foundation and providing enhanced structural support for the entire building.

Sealing Joints in Concrete Structures Prone to Movement
Concrete structures that experience movement (due to temperature fluctuations, settling or other factors) require flexible solutions to prevent cracking and water ingress. PU chemical grouting seals these joints and provides the necessary flexibility to withstand the natural expansion and contraction of concrete structures.

EMERGE INFRA’s PU Chemical Grouting Process

Our team follows a detailed and methodical approach to applying PU chemical grouting, ensuring precision, durability and effective waterproofing:

Detailed Site Survey and Crack Mapping
We begin by conducting a thorough site inspection, identifying all cracks, joints and voids that need treatment. Using non-destructive testing methods, we assess the extent of the damage and plan the grouting process accordingly.

Installation of Injection Ports and Sealing of Injection Surface
After identifying the cracks or voids, we install injection ports along these areas and seal the surrounding surface to contain the PU resin during the injection process. This step ensures controlled and efficient resin flow.

Controlled Pressure Injection of PU Resin Using Specialized Pumps
We use specialized pumps to inject the PU resin under controlled pressure. This allows the resin to deeply penetrate the cracks and voids, ensuring a complete and even fill, creating a durable and flexible seal.

Monitoring of Resin Flow to Ensure Complete Filling of Cracks and Voids
Throughout the injection process, we carefully monitor the flow of PU resin to ensure complete filling of the cracks and voids. This ensures that there are no gaps left in the waterproofing barrier.

Post-Grouting Inspection and Water-Tightness Testing
After the grouting process, we perform a post-grouting inspection and water-tightness testing to verify that the seal is fully effective and that there are no leaks remaining.
