Foundation Problem Signs in Charleston

Your Charleston home depends on the stability of your foundation. As your foundation becomes damaged, certain problem signs can help you identify exactly what is going on. You may notice wall cracks forming both inside and outside the home. Additionally, you might notice the floors of your home becoming uneven and separating from the floorboards. Doors and windows may also become harder to open as the walls of your home shift. All of these can be exasperated by the humid environment of Charleston, as wall cracks may allow humidity levels to rise within your home, costing you even more money! 

Bowing Foundation Wall

Bowing Walls

Foundation walls move inward primarily due to expansive soils and hydrostatic pressure on the walls from outside.

Drywall Nail Pops

If your foundation becomes damaged, the walls in your home may begin to shift. This can cause nails to pop out of wall studs and put holes in your drywall.

Collapsing Retaining Walls

Retaining walls serve to retain the lateral pressure of soil. More simply, retaining walls are used to hold back soil and substrate from moving due to the effects of gravity and erosion

Floor and Wall Gaps

Almost every structure in your home depends on the health of your foundation. When your foundation gets damaged, so do important structures such as walls and floors.

Causes of Foundation Damage in Charleston

Homeowners in Charleston know that the area is wet year-round. Humidity is a common occurrence in the area, rain falls most often during the late summer, and the city itself is located along the Charleston Harbor. Since moisture is so prevalent in the area, the sandy and sandy loam soil can become abnormally wet as a result. When water builds in the soil, it can cause erosion and muddiness. Soil washout is a term used to describe this process. As rain falls and permeates the soil, it becomes soft and weak to the point that it can no longer support your foundation. Additionally, water below the soil causes hydrostatic pressure to press against the walls of your foundation and cause additional damage.

Causes Of Settlement

There are many factors that can contribute to a shifting foundation. The most common of these factors are unstable soils, poor drainage and plumbing leaks, poor grading or compaction and tree roots.

Foundation Soils

Soils are composed of different ingredients like sand, silt, loam and clay. These ingredients determine how soils behave under wet and dry conditions and when they need to support weight.

Fill soil

Improper Grading

When the filled in land has been improperly compacted, foundation issues can arise. Back-filled soils are not necessarily unstable.

Foundation Repair Solutions in Charleston

Foundation repair works to remove wet soil from the equation. When it comes to concrete slab foundations, our team implements pier systems to stabilize them. With three different pier designs available, you can be sure that Mount Valley solves your foundation problem with the most efficient solution. We also repair crawl space foundations with our steel crawl space supports which work to defend against collapsing floors brought on by Charleston’s constant storms and humidity. Furthermore, we have a wall repair system for basement foundations which stops the walls from bowing outward and cracking.
