Foundation Inspection

Yesterday I learned about foundation inspection. Lot of areas in USA have expansive soils problems, so houses constructed on these shrink-swell soils will get structural cracks due to settlement. Houses which are constructed in mid 70's they have slab on grade foundation and that too just 5-8 inches thick slab. The soil is the main problem for these kind of problems. Now they are using lifting technique to hold the house at certain level without settlement. They insert concrete cylinders surround the house until they reach hard surface, now they will put concrete blocks above it. Now they will lift the house using heavy hydraulic machines and insert steel bracing's between cylinder and block. This is called uplift technique which is cheap, economical, fast which is using by most foundation repair firms in Dallas area.
