There are situations around the country where certain locations of homes have a problem with foundations that shift, sink or otherwise become compromised by shifting soil. If the soil is too sandy or perhaps consists of too much clay, it can move and shift causing the foundations to crack and otherwise move.
The thing to do is to contact a foundation repair contractor Austin TX to look into the situation and to make recommendations as to what can be done to rectify the situation.
In most cases the best remedy is to dig underneath the foundation area where the problem is most apparent and shore up the foundation with jacks, jacking it up to its original level. Then by installing permanent piers of concrete or steel, the foundation can be supported and reinforced.
The earlier foundation repair can be done, the better, because less damage to the home will result if this erosion can be stopped early on.
