Crawl space or wet spaces are different from basements in such a way that these areas are underutilized and most of the time, it doesn’t have frequent guests and often uninhabited. Its main use is for wiring and plumbing system access. The main problem is it can easily get wet due to weather conditions so it’s also called wet space.
Unattended wet spaces can reveal the most hideous structural and health concerns for any occupants of any building or home. Since these small spaces are not readily available, it’s also highly advisable that you get a home inspection done before you do any required clean up and solutions. The biggest advantage of having house inspections in Toronto is that we’ll make sure none of the problems we’ll see will become a major problem again.
Types of Crawl Space
Wet space designs greatly depend on basement structure. Slab on grades, quad split level, two story house on full basement and shallow basement or cellar crawl space can be easily set up for cleanup, inspection and remediation. However, logic, building codes and even the US EPA dictates that moisture control would be impossible for crawl space built on homes that are in flood zones, those with dry and marine climates and raised pier foundation types of home with no walls.
Let’s talk about moist
Keeping water out of your basement is of utmost concern. What’s tricky is finding out where it usually comes from. Two likely suspects include the gutter and downspouts running off too close to the walls. We can recommend damp proofing if your home has not yet undergone such a procedure.
Other less invasive procedures include simple landscaping or light carpentry if at all applicable. We generally do not want homeowners in Toronto to do any heavy excavations as these procedures are costly unless necessary. Waterproofing on the other hand is less common such as asphalt seals, double weeping systems and wall joints. All these must be approved by local building code authorities first though.
Some moisture problems aren’t caused by water vapor at all caused by airflow bringing in water vapor. This problem can cause long term structural damage that goes unnoticed because it happens slowly over time. We can recommend adding vapor barriers, plastic over walls, or attaching any barrier material with caulk or adhesive whichever is more suitable for the situation at hand.
Insulation solutions for Crawl Space
Crawl space insulation is highly recommended for homes located in dryer regions. It helps keep airflow out to keep the place dry and warm. You can use closed cell-spray foam insulation even on irregular walls while rigid board insulation for poured foundations. Fiberglass insulation, though more affordable, is less recommended because without air barriers, it is still highly ineffective.
Crawl Space Ventilation may also be key
Sometimes, simple ventilation is key to keep the wet space warm and moist free. Humidity problems can occur for basements located in mixed climates so venting is not a possible solution. However, for more moderate climatic regions, a simple exhaust fan or conditioned air is already enough.
You should be notified though that any of these remediation procedure we discussed are aftermarket waterproofing so if you’re building a new home, better ask authorities and professionals what best processes can be practiced to keep your crawl space warm and dry.
