These foundations have for ages been popular because they could 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.
The disadvantages
For one thing, a crawl space can be dark, damp and crowded. If you need function in this confined space, it’s not really easy. Insects and rodents are common inhabitants in unfinished spaces, and these people could actually damage insulation, wood and electric. Unless a crawlspace recently been properly sealed and waterproofed, moisture is likely to be a problem. Excessive moisture in this enclosed space will enable mold to grow and can cause wood to get rotten. If it contains ductwork, HVAC components or even perhaps a water heater, most is likely regarding damaged as steel parts rust. Radon is another possible concern, especially this has a dirt floor.
Types of crawl space foundations
Most of these foundations have poured concrete or concrete block perimeter walls. A typical foundation may have at least one vent (usually a screened opening) per side and a certain access door. The foundation floor can be dirt, poured concrete, or dirt is actually covered with a moisture barrier; paid traffic . two options tend to be desirable. Mid-span support is often required for floor joists that span between walls, and this typically provided by posts that rest on concrete piers or footings.
Fixing the problems
Bad conditions can easily effect relaxation of home and those in out. 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 a fishing rod. If this is the case, or maybe if the floor above the crawl space has sagged or become too springy, professional repair will be also necessary. A specialized foundation repair contractor can able to determine if waterproofing and/or encapsulation are called for to solve moisture matters. Radon mitigation is often included the foundation repair contractor performs encapsulation work. If the first floor in the house is uncomfortably cold during winter months, the ground and walls might require air sealing and extra insulation.
