These foundations have always been popular because they can be built quickly and more economically than basement foundations. When properly constructed, a crawl space foundation provides a solid, secure, long-lasting base for a building. The walls and posts elevate the wood framing above ground level, allowing the first floor to be insulated easily while also helping to protect wood from being damaged by moisture in the soil.encapsulations offers excellent info on this.
Types of crawl space foundations
Most of these foundations have poured concrete or concrete block perimeter walls. A typical foundation will have at least one vent (usually a screened opening) per side and a single access door. The foundation floor can be dirt, poured concrete, or dirt that is covered with a moisture barrier; the last two options are more desirable. Mid-span support is often required for floor joists that span between walls, and this is usually provided by posts that rest on concrete piers or footings.
Fixing the problems
Bad conditions can easily effect the rest of the house and the people in it. If the walls have cracked, bowed or crumbled, these structural issues should be corrected by a foundation repair specialist. Foundation posts sometimes shift off their supports. If this is the case, or if the floor above the crawl space has sagged or become too springy, professional repair will also be necessary. An experienced foundation repair contractor will be able to determine if waterproofing and/or encapsulation are called for to solve moisture problems. Radon mitigation is often included when a foundation repair contractor performs encapsulation work. If the first floor of the house is uncomfortably cold during winter months, the floor and walls might require air sealing and extra insulation.
