If you own your home and know that you have a foundation problem which requires repair but you are not sure where to begin searching for solutions, you can begin by identifying what type of foundation you have. There are many types of foundation construction which have been used over the last 100 years in this area of the country. Some of the most common foundation types include Cast in Place Concrete, Concrete Block, Fieldstone and Limestone, Red Brick and Telephone Tile.
One of the most common problems we see with concrete foundation walls is that they are not properly secured or connected to the floor framing. This is usually caused by a lack of toe nails connecting the floor joists to the sill plate, an inadequate number of anchor bolts connecting the sill plate to the foundation wall, or improperly placed anchor bolts which cause the sill plate to split.
Horizontal cracks in concrete block, or cast in place concrete foundation walls, are rarely an indication of foundation settlement. In concrete block foundation walls horizontal cracks are typically caused by the foundation wall being forced and bowed inward under the lateral or inward pressure of the soil.
When encountering poor soil conditions on a building site it may be necessary to transfer the building loads to deeper more stable soils. Determining the most effective and economical solution to this problem will generally involve an investigation of the soil conditions which is typically done with a soil boring.
Interior walls which support floor or roof loads (a bearing wall) must line up over or very near a supporting beam line, a foundation wall, or another bearing wall. Improperly located bearing walls may cause excessive deflection in your floor system, over stressed floor framing, and cracked floor joists.
