During the building process, holes are cored in foundation walls for the installation of sewer, electric, gas and oil lines. Often times, the gap between the wall and pipe itself is either improperly filled by the builder or not filled at all.
Pipe penetrations in the foundation walls are often sealed the contractor with hydraulic cement. When attempts fail the homeowner or contractor usually then reapply more hydraulic cement, caulking or just about anything else they can find. Including the magic of an As
Seen on TV product called Flex Seal. These attempts fail because concrete expands and contract due to temperature changes and the difficulty of bonding to two materials, namely a pipe and concrete. Cracks and/or voids are created in the patch, compromising the seal and allowing water to penetrate causing a basement leak. Water will fill behind the patch and you will notice a white powdery buildup (efflorescence) that pushes minerals through the concrete and assists in breaking down the seal. That is the first telltale sign that the seal is compromised.
A-1 Foundation Crack Repair uses the preferred method by using an electric pump to inject high viscosity closed-cell polymer resins that seals and encapulates the pipe penetrations for a proper seal. The big advantage to this method is that the seal has elasticity, allowing for the natural expansion and contraction of the foundation walls. Furthermore, the closed-cell polymer resin can expand up to 50 times its original volume, filling the small voids and crevices that cannot be seen with the naked eye.
