Causes of foundation failure and removal measures

 Causes of foundation failure and removal measures



1,Poor Ground Preparation

Cut and fill situations should be properly prepared before the structure is started or it may result in improperly compacted soil beneath the foundation.

2,Transpiration

Vegitation, such as trees, shrubs, or other plants, near a foundation can affect moisture levels. Tree roots can dehydrate the soil beneath a home causing soil shrinkage and settlement of the home.

3,Drainage

Improper drainage will lead to excess moisture build-up, which could erode or consolidate soils. Excessive moisture may cause heaving of expansive clay soils. Remedial measure is proper drainage and compaction

4,Poor Building Site Preparation

Cut and fill situations, where the soil is removed from part of the building site and stacked on another, needs proper soil stabilization before a structure is built; otherwise unexpected movements of the soil beneath the foundation may occur.

5,Poor Ground Preparation

Cut and fill situations should be properly prepared before the structure is started or it may result in improperly compacted soil beneath the foundation.

6,Poor Soil Conditions

Poor soil, organics.....etc., may cause expansion or consolidation, which contribute to foundation failures. Using the correct foundation repair system can counteract the above conditions. Steel piers and helical piers are often the solutions for your basement or foundation.
