Basement Waterproofing in Charleston

Many homeowners in Charleston, SC, opt to have their basement waterproofed by a reputable company like Mount Valley Foundation Services. Basement waterproofing is an excellent way of keeping water out of your basement, protecting the structural integrity of your home, as well as any personal belongings stored in the basement. Due to the sandy loam soil found in the area, it is more common for homes to have a slab foundation; however, some homeowners in Charleston opt for a basement in their homes. When a homeowner chooses basement waterproofing, they can expect the installation of a drainage system, basement sump pump, dehumidifier, and vapor barrier. Protect your home against excess humidity, mold, and more by having your basement waterproofed.

Causes of seepage in your basement

Basement Water Seepage

Combating seepage is about more than preserving your quality of life. If your home plays host to too much dampness, you can start to see the consequences not only in your home’s value but in your own health.

Causes of Basement Damage in Charleston

In Charleston, most of the causes of basement damage are due to environmental factors, as well as faulty construction. Hydrostatic pressure happens when water is absorbed by the soil, the soil becomes heavy as the water is absorbed. Once it is heavy enough, it begins to push against your basement walls, where the water will find its way in through cracks or the porous concrete. Sandy loam soil is very permeable, so water can easily seep inside to create this pressure.

Knowing what causes basement water damage in your home is important. When you know what causes the damage, you can get a better idea of how to prevent this damage from happening to your basement. Below, we’ll name several of the causes of basement water damage, including hydrostatic pressure and leaking pipes.
