Combatting Basement Water Woes in Guelph
When the rainy season hits Guelph each year, a significant number of residents encounter the frustration of damp and leaky basements. This issue often stems from inadequate or non-existent basement waterproofing systems. Rainwater that saturates the soil around your basement can seep through cracks and openings, infiltrating your basement walls. This unwelcome water intrusion leads to foundation wall damage, fostering the growth of mold and mildew, which can pose serious health risks. The absence of a robust defense mechanism subjects your walls to hydrostatic pressure, exacerbating existing cracks and vulnerabilities. This pressure arises from stagnant water persistently pushing against your walls.
This cascade of events transforms your basement into a perpetually damp, musty-smelling space plagued by mold. The structural integrity of your foundation walls is also compromised, leaving them prone to further deterioration. Consequently, your basement becomes underutilized and ineffective. Yet, your basement holds the potential for so much more. Enter GJ MacRae, your trusted ally for basement waterproofing in Guelph, committed to delivering you a dry, impervious basement.

The GJ MacRae Solution: Basement Waterproofing in Guelph
Our comprehensive basement waterproofing process begins by meticulously identifying all wall cracks.
After preparing the area, we apply hydraulic cement to seal the cracks, followed by a quick-drying primer for enhanced adhesion. A layer of specialized Hydroshield is then meticulously applied, fortified by a layer of flexible fiberglass mesh.
This is followed by a second Hydroshield layer for double protection. A thick plastic layer is added, and a Platon drainage board safeguards the membrane during backfilling.
We ensure your weeping tile drainage is functioning optimally, and backfilling is performed with precision. The result is a quadruple-layered waterproofing solution that guarantees the longevity of your dry basement.
