Being a Home Inspector In McKinney for many years I have seen that if home owners would just put a small effort in their maintenance around their home it could save them thousands in repair in the long run.
This is the first of a four part seriesd on foundation maintenance
Foundation Maintenance Program
Highly plastic clay soils, as are typically found in the DFW area, exhibit a great amount of expansion and contraction caused by seasonal moisture changes and varying weather conditions. Clay soils that become too dry will shrink and not be able to maintain the physical elevation of a structure's foundation. High ambient temperatures and long periods of inadequate rainfall can cause moisture loss several feet below the surface and take a devastating toll on foundations in the DFW metroplex. Conversely, clay soils that become overly saturated can lose their load-bearing capacity. Guidelines regarding residential foundations and soil moisture changes:
Tip # 1 - The key to maintaining foundation elevations is proper drainage. Water should always run away from the house with no pooling of water near the foundation. Soil should be about 2 inches below the top of the perimeter grade beams, and slope about 1-2 inches per foot for a minimum of 18 inches away from the perimeter. It is recommended to place fill dirt at perimeter grade beams, gutters, and splash blocks under downspouts. Only clay-like soils should be added around the perimeter, NOT porous or sandy soils.
Most major foundation movements can be prevented if the active supporting soil is well maintained. The extent of distress will be lessened and the service life of the residence will be considerably increased.
If you have any questions at all, please reply or as always, call me!
