These foundations have always been popular because they could be built quickly and more economically than basement play blocks. 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 inside of soil.
The disadvantages
For one thing, a crawl space can be dark, damp and cramped. If you need to function 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 electric. Unless a crawlspace is properly sealed and waterproofed, moisture is probably going to be difficult. 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, substantially is likely for damaged as steel parts rust. Radon is another possible concern, especially can has a dirt floor.
Types of crawl space foundations
Most of these foundations have poured concrete or concrete block perimeter areas. A typical foundation could have at least one vent (usually a screened opening) per side and a certain access door. The original source floor can be dirt, poured concrete, or dirt is actually covered with a moisture barrier; final two options much more expensive desirable. Mid-span support is often required for floor joists that span between walls, and this frequently provided by posts that rest on concrete piers or footings.
Fixing the problems
Bad conditions can easily effect in conversation with of home and folks in this kind of. 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 will be the case, or if the floor above the crawl space has sagged or become too springy, professional repair will be necessary. A specialized foundation repair contractor will be able to determine if waterproofing and/or encapsulation are requested to solve moisture symptoms. Radon mitigation usually included every single time a foundation repair contractor performs encapsulation the job. If the first floor of this house is uncomfortably cold during winter months, flooring and walls might require air sealing and higher insulation levels.
