These foundations have for ages 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. Wall surfaces can remain and posts elevate the wood framing above ground level, allowing the first floor to be insulated easily while also helping protect wood from being damaged by moisture in the soil.
The disadvantages
For one thing, a crawl space can be dark, damp and pain in. If you need to work in this confined space, it’s not easy. Insects and rodents are common inhabitants in unfinished spaces, and they can actually damage insulation, wood and wiring. Unless a crawlspace is properly sealed and waterproofed, moisture is probably going to be any trouble. Excessive moisture in this enclosed space will allow mold to grow and can cause wood to go rotten. If it contains ductwork, HVAC components or even perhaps a water heater, substantially is likely with regard to damaged as steel parts rust. Radon is another possible concern, especially if it has a dirt floor.
Types of crawl space foundations
Most of these foundations have poured concrete or concrete block perimeter membranes. A typical foundation will have at least one vent (usually a screened opening) per side and a single access door. The original source floor can be dirt, poured concrete, or dirt is actually covered with a moisture barrier; the last two options costly desirable. Mid-span support is often want for floor joists that span between walls, and this is provided by posts that rest on concrete piers or footings.
Fixing the problems
Bad conditions can easily effect relaxation of the home and folks 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 a fishing rod. If this may be the case, or maybe the floor above the crawl space has sagged or become too springy, professional repair will even be necessary. A talented foundation repair contractor always be able establish if waterproofing and/or encapsulation are recommended to solve moisture drawbacks. Radon mitigation is included every single time a foundation repair contractor performs encapsulation labor. If the first floor in the house is uncomfortably cold during winter months, flooring and walls might require air sealing and extra insulation.
