THE PROBLEM
A young couple recently purchased a starter home in Regina, SK, and were concerned about a large crack in its foundation wall, causing persistent water seepage and subsequent interior water damage. Exterior repairs were deemed too expensive. The homeowner required a long-lasting, non-invasive method to eliminate water infiltration and safeguard the basement before completing their basement renovation.
THE SOLUTION
Eco Seal suggested using a one-part polyurethane sealant to effectively seal cracks in underground structures. The sealant’s thin consistency enabled thorough penetration into the cracks, creating a waterproof barrier. The application involved a detailed six-step injection procedure.:
- Drilling: Small-diameter holes were strategically drilled along the crack to intercept it and allow injection points.
- Injection Port Installation & Water Testing: Ports were installed at drilled points and tested with water to confirm crack interception and flow paths.
- Injector Ports & Sealing: The surface of the crack was sealed with hydraulic cement to contain the injection.
- Mixing & Testing: The polyurethane sealant components were mixed, and small test batches were used to confirm reaction times and ensure optimal formation.
- Injection & Solidification: Using a pump, the polyurethane sealant was injected, filling the entire crack from bottom to top, penetrating tight spaces, and forming a flexible, watertight seal.
- Port Removal & Patching: Once the sealant was fully cured, the ports were removed, and the drilled holes were patched for a clean, finished
THE SUMMARY
The Eco polyurethane sealant injection successfully sealed the foundation crack, eliminating water seepage and restoring the lower level to a dry condition. The low-viscosity polyurethane sealant effectively permeated the crack, forming a long-lasting waterproof barrier. Unlike rigid repair materials, the flexible nature of the polyurethane sealant allows for minor foundation movement without compromising the seal. The use of a pump made the injection process efficient and precise.
The project provided a non-invasive, cost-effective, permanent solution, preventing further water damage, giving the homeowners peace of mind. This project delivered a lasting, affordable, and non-disruptive solution, halting additional water damage and ensuring homeowner confidence. .
