FOUNDATION PIERING, BY MIKE FOURNIER, TULSA
Cracks around your house may be indications of foundation problems. Cracking, sinking, or shifting of the foundation can put the entire house at risk of collapse. It is a good idea to regularly check for brick walls or chimney cracks, and drywall fractures. And remember to check in the basement too. When you find problems, it is smart to address them immediately. Remedies are available and the most common is the installation of wall anchors.
Geographical Moisture Problems. Foundation problems can occur in the areas due to a high water table and the ground being saturated with rain and snow. Underground water can seep next to a foundation, and then form pressure, and, in time, will find a way to leak through any porous, concrete material. The resulting water absorption will crack or bow the foundation. This can happen especially in older homes that are constructed of concrete block. Also, this can happen when downspouts are not properly placed, gutters are not cleaned, or walls are not regularly examined. There are affordable solutions to the problems.
Anchored Walls. Previously, foundation cracks called for significant repair methods, such as digging around the foundation and building new basement walls. All that is costly, requires lots of man power, and time. A simpler, easier method to save the home’s support system is anchored walls.
How They Work. Contractors will dig outside the house. They will dig several holes, by hand, a safe distance away from the house. Next, inside the basement, they will drill several small holes – a few yards apart – into the foundation. Then, they will drill a long pipe - called an anchor rod – through each one. These anchor rods slide almost all the way through the wall, going several feet into the earth. Following that, they will install two metal plates onto the pipe – one plate rests against the interior wall and the other plate rests against the exterior – creating a brace. Inside, a lug not is placed onto the exposed piping and tightened against the interior plate. This literally squeezes the wall back into place. Last of all, the outside holes are backfilled and the sod replaced. This entire process will take less than one day.
