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.

Excellent service from beginning to end. We would highly recommend this company. Dean assessed the problem (water leaking into our furnace room as a result of a window well that another company had incorrectly installed previously) and provided a thorough estimate detailing every aspect of the project. He then scheduled the job to be done before the big winter storm that had been forecast. The crew arrived exactly on time and completed the job, to the very best professional standard, in less than a day. We are so glad we chose G.J. MacRae. Thank you very much.

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.
