Before & After Photos

In Saint-Cyprien, our client was dealing with a damp crawl space, with soggy soil, persistent odors, heavy air in the house, and a real risk of mold, wood deterioration, and problems related to excessive moisture. The space contributed to increased indoor humidity, affecting comfort and air quality.

To remedy the situation, we first installed a drainage membrane on the floor to capture water from the ground and efficiently direct it to the drainage point. Next, we completely encapsulated the crawl space with CleanSpace membrane, creating a waterproof barrier against moisture, water vapor, and infiltration from the ground. To stabilize humidity levels and improve indoor air quality, we added a SaniDry Sedona dehumidifier, designed to continuously control humidity and reduce the risk of condensation and odors. Finally, a SmartDrain pump was installed to automatically drain water from under the membrane, preventing future accumulation.

Today, the crawl space is clean, dry, and protected, contributing to better energy performance, protection of the home's structure, and a healthier environment year-round. This project demonstrates the importance of a comprehensive approach combining drainage, encapsulation, dehumidification, and active water management for a sustainably sanitized crawl space in Quebec.

We repaired the basement slab that was sagging at this house in Verdun. Symptoms can be clearly seen in the cracks existing throughout the wooden support columns in the crawl space. By installing our slab piers, we stabilized the slab and the sagging floors in the upper house.

Our client from Hochelage, Montreal started noticing Drywall cracks throughout the house in addition to sagging floors which made him contact Systèmes Sous-sol Québec’to  have his crawl space encapsulated.

In this picture you can see the big difference between an encapsulated and an uninsulated crawl space.

The insulation helped solve many issues the client had, and had improved the home comfort, healthfulness, energy efficiency and value of the house by insulating the upper floors from the cold, making the Crawl Space clean and letting her use the crawlspace as an additional storage room.

We have fixed our client’s foundation wall cracks in Pincourt, that had water seeping through those cracks, through injecting our Flexispan, polyutherane and SentrySeal injection.
