Using Polymer Injection As a Foundation Repair Method


Foundation repair needs are dominant and need attention immediately all over the U.S. Some homes lie in an earthquake zone which means that the smallest of hairline cracks can turn into a malady of monstrous proportions, if attention and expertise is not diverted to it as soon as it is noticed.

The Need For Foundation Repair

Most people assume that concrete has a tendency to develop cracks and it is alright to leave the problem unattended. This couldn’t be farther away from the truth. While foundations of homes crack due to old age or damage during earthquakes, they need to be dealt with immediately. Ask yourself questions such as these:

  • Do you have any cracked walls in your home?
  • Are these cracks large enough for a dime to fit through them?
  • Are you suffering with doors that just refuse to close?
  • Are your floors bulging and fattened?

If the answer to any of these questions is a yes, then it is best to contact a foundation repair contractor at the earliest time possible. Other signs that foundation repair is needed are uneven floors, separation of walls from doors, leaning chimneys, and cracks in the tiling or vinyl flooring.

Many times foundation problems may not be easy to detect and it is a good idea to consult an experienced contractor to obtain a foundation inspection conducted. A qualified contractor will know exactly where to look for damage and will be able to spot problems easily and quickly.

Repair Methods

Depending on the problem that you are facing, there are a variety of repair methods that can be put to use. Treating the symptom with patching and filling repairs is not a permanent solution to soil settlement problems. Eventually, people learn that it’s necessary to correct the cause of the structural problem. The most common of all these methods is Polymer Injection.

Polymer Injection is a soil stabilization and jacking process that resembles mudjacking. The main difference is that instead of pumping a cement-based slurry into the soil, a polymer-based expanding foam is injected. The two-part polymer starts turning from a liquid into a foam as soon as the two components are mixed at the application nozzle. Polymer injection can be performed directly beneath a settled structural element, or at depths of 30 ft.. Based on penetrometer tests that assess soil density, technicians establish an injection grid to target specific locations where the polymer must be placed. Holes are drilled in the slab or other structural element according to the injection grid; then a length of tubing is inserted in each hole. Tubing lengths vary based on the different injection depths that have been established.

Someone You can Trust

The right method can be prescribed to you by your local foundation repair contractor. You will also receive reliable and usable information on how to prevent foundational problems in the future. Remember, foundation problems will not magically fix themselves over night, they will only get worse. This is why you need to act immediately to fix your foundation problem once and for all.
