Stabilization of Floor Joists and Installation of Drainage System in Crawl Space in Longueuil, QC
Challenge
Our client, Ms. Isabelle, noticed issues of humidity and infiltration in her crawl space, as well as a weakening of the floor joists in her house. She aims to solve the mold problem, improve energy efficiency, and stabilize the floor joists in her crawl space.
Resolution
Our experts at Sous-Sol Confort conducted a free evaluation and recommended a comprehensive solution to meet our client's needs. We propose the installation of a FlowDrain drainage system and a SumPlus sump pump system to eliminate infiltrated water and direct it away from the house, ensuring a dry and comfortable crawl space.
The first step involves creating a trench along the internal perimeter of the crawl space, at the joint between the wall and the floor, to install FlowDrain drains on a gravel bed. Next, we recommend the installation of 9 SuperJack support posts to stabilize the floor joists in the long term. Before pouring a new 4-inch thick concrete slab with a 25MPA resistance, we install the Delta MS drainage mat. To evacuate infiltrated water, we will install a SumPlus sump pump system. This system includes a perforated receptacle installed two feet deep in the ground, along with a powerful pump and a hermetic cover with a floor drain. An integrated alarm sounds when the water level exceeds the pump's trigger threshold. The water is then expelled from the house via an independent SafeGard discharge line.
With this comprehensive solution, Ms. Isabelle will benefit from a dry and well-insulated crawl space, solving the humidity problem and improving the energy efficiency of her home. Additionally, the SuperJack support system will guarantee the long-term stability of the floor joists and main beams.
