Crawl Space Repair Before & After Photos

Mrs. Cuff wanted like to use her crawl space for storage, but it was very humid. Since she wanted to keep her belongings in good condition and avoid mold, she wanted to find a solution. So, she decided to contact Systèmes Sous-sol Québec in order to resolve the humidity problem quickly.

The solution for our client was to first install a SmartSump sump pump system. It is connected with a discharge line which will expel the water away from the foundation of the house. Then, a drainage mat was placed on the ground so that the water that ends up on the surface goes directly to the SmartSump. Finally, our CleanSpace coating is installed over the drainage mat. Material with a thickness of 20 mm composed of polyethylene and antimicrobial, it blocks moisture from the soil and prevents the proliferation of mold. It also gives a clear and bright appearance to the crawl space.

With this solution, Mrs. Cuff will be able to use her crawl space as storage space and above all have a dry crawl space!

Mr. Woods has an earthen crawl space with several problems:

- Water infiltration

- Humidity

- Mold

When it rains or during spring, water infiltrates in his crawl space creating a lot of humidity and mold over time. Another source of moisture is the earthen ground. The water in the soil evaporates creating moisture.

All of This has affected the comfort of his home, as his floors were cold and there was a smell of dampness in the house.So he contacted Systèmes Sous-sol in order to isolate his crawl space and resolve his problems definitively.

The solution

First, the mold on the wooden walls was removed with our Mold-X product. Then, our experts installed our SilverGlo insulation panels on the walls of the crawl space. 2 '' thick panels with radiant barrier to isolate the cold and reflect heat inside the crawl space. They then laid our TerraBlock insulation sheets on the earthen floor. They made it possible to insulate the crawl space and protect it against humidity. Finally, our experts installed our CleanSpace coating on top of the TerraBlock. Moisture is therefore blocked, it protects the TerraBlock insulation sheets and crawl space into a clear and clean appearance.

The crawl space was damp and very poorly insulated. The floor were sagging and needed support.

Solution:

•Installation of the SilverGlo to enclose the air outside the house

• Application of an urethane foam to insulate the crawl space

• Installation of a drainage membrane and a CleanSpace to isolate the house from the earth and make the crawl space cleaner.

• Installation of a SmartJack to support the house.

This client contacted us initially to fix his humidity problem in his crawlspace, but while we were there, we noticed that there was a very large crack in the foundation wall of the crawl space.

We fixed this issue by installing the PowerBrace system. It consists of zinc coated beams and components. PowerBraces utilize a joist reinforcement that distributes the load evenly. The crawl space is now stable and sealed.
