Crawl Space Repair Photo Album: Insulation of a crawl space in Saint-Jean Sur Richelieu

High relative humidity cause many bad things in your crawl space, and there are few things that cause high relative humidity: Leaking groundwater through the crawl space walls, exposed earth on the floor or open vents to the outside. This is why our clients from Saint-Jean Sur Richelieu contacted us asking for our help. We have strongly advised to insulate his basement as quickly as possible with our CleanSpace membrane that is used to encapsulate crawl spaces and line basement walls for protection against moisture and mold, and waterproof it with our interior drainage system and our SuperSump pump system.

Fiberglass isolation is a bad idea

If the insulation is not properly sealed off it can get into air vents and circulate through the building. Fiberglass insulation is not generally considered to be dangerous, but it can irritate the skin and respiratory system.

Effloresence on the walls

Efflorescence is a sign that there is water infiltration in the area.

Putting a fan in the crawl space is not useful at all

Any kind of fans, whether big or small will not be able to remove the moisture from the crawl space.

Old sump pump in our client's crawl space in Saint-Jean Sur Richelieu

Pedestal sump pumps often lack the power needed to pump out large quantities of water during a storm. Therefore, if a rain storm drops a large volume of water in your area, a pedestal sump pump may not be able to pump out the water fast enough to keep your basement from flooding.

Replacing the old sump pump with the new sump pump system

We installed the SuperSump pump that is way more efficient then the pedestal pump. It also has a strong, airtight sump cover lid, making it child-safe, and will also keep out insects, odors and radon gas.

FlexiSpan crack repair inserted on the crawl space walls

The FlexiSpan can’t leak or reopen like mortar-based repairs and it permanently stops water leakage through basement wall cracks.

CleanSpace membrane installation

The CleanSpace is created from high density polyethylene. Polyester cord reinforcement allows it to be mechanically fastened to the walls so it will never fall off. There are several different options when it comes to CleanSpace: it ranges from 8mm to 20mm thick, and environmentally-conscious homeowners can even choose a recycled option.

Installation of the SaniDry Dehumidifier

Mold and mildew thrive in moist conditions, like the basement and crawl space. Dust mite droppings are the number 1 indoor allergen. A SaniDry dehumidifier will keep your home below 55% relative humidity, so mold and dust mites won't survive.
