CASE STUDY 2-
FOUNDATION WATER SEEPAGE INJECTION REPAIR
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 appearance.
