Why do walls crack and push?
The main reasons for foundations walls to push are: (a) faulty grading of ground around the structure, (b) freeze and thaw, (c) clay soil swelling, (d) back filled to early, (e) sinking concrete porches, and (f) water rotting the hollow block foundation where the block touches the footer. Fortunately, there are various ways to fix the foundation walls. To name a few, D- Bug Waterproofing can install wall anchors, replace pushed foundations, install concrete retaining walls, and support pushed foundations with I Beams. We can replace the foundation wall(s) if it has collapsed or pushed too far. This is done by jacking up and supporting the house. Most of the time, we replace the wall with concrete block or poured concrete walls. Then, an outside French drain system is installed.
Concrete Retaining Wall System
We install concrete retaining walls for foundations that are pushed beyond the point of using wall anchors, the bottom row of block is pushed off the footer, or if the block is deteriorating. A concrete retaining wall consists of digging down beside the footer on the foundation wall, installing re-bar every square foot and pour a cement wall 8 to 12 inches thick against the foundation wall.
I-Beam Retaining Wall System
Installation of I-beam retaining wall systems: Supporting pushed foundations with I beams involves jackhammering a hole in the basement floor, placing the I beam under the basement floor and extending it up the wall and into the floor joists. Next, D-bug Waterproofing cements the bottom into place. Then, we brace the top to the floor joists with wood, using the weight of the house or dwelling and weight of the cement floor to stabilize the foundation wall. (I beams are used in applications where you can’t install wall anchors.)
