Sinking or settling foundations are usually due to bad drainage, ground movement, subsidence or poor construction, which causes your foundation to shift or settle. Your foundation repair problem will usually be noticed by sticking doors or windows, or drywall cracks. Incomplete or failed waterproofing around and under basement walls and floors is a significant cause of sinking or settling foundation problems.
Keep on the lookout for things like windows and doors becoming stuck or misaligned. Watch for cracks in basements, slabs, and on walls in the living areas of the house. Water puddles that form around the base of your home may also indicate a sinking or settling foundation, as can upheaval of floors or floors that gradually become sloped or badly cracked.
Upper level soils, typically 6 to 8 feet below ground level, go through wet and dry cycles due to seasonal moisture and temperature changes. When there are drastic changes like a heavy rain fall right after a drought, water moves through the soil at greater rates than normal. This water looks for the path of least resistance, if this path is through or under your foundation, settlement and crack will start to appear.
Soils with heavy concentrations of water can double in weight causing hydrostatic pressure to press against your foundation, or consolidate soils. This consolidation can cause your foundation to sink due to the lack of support.
If you’re experiencing a sinking or settling foundation, call in a foundation expert to analyze the problem. Foundation repair contractors work directly with foundation engineers to carry out the plan the engineer developed to keep the foundation from sinking or settling.
