Options for repairing of foundation varies greatly based upon the geographical conditions of the area. Till 1970, people usually repaired the foundation by using only concrete, however nowadays many other types of foundation repairs are available.

 Following are few different approaches for repairing the foundation.

  • Steel piers

When this method was introduced it really revolutionized the repair process for foundation. It is possible to do the repair work much faster as compared to traditional concrete pier method of repairing. Nowadays a lot of innovations have been done on this method and it has become a data driven process.

  • Helical piers

Whether it is internal slab repair or external foundation repair, helical pier can work well for both the areas. Also, if it is any new construction or for any foundation repair, it is possible to employ this method. Porch column areas or structures which are having vinyl siding that are light-loaded areas are the right place for undertaking this method. This method is quite versatile however much underused in the market.

  • Concrete pier

Most of the foundation companies use this pour-in-place technique by using concrete piers during pre-construction phase of any building structures. The same methods are also used during repair of foundations too. Before the hydraulic driven steel pier method was in the market, people used to adopt this method only.

This is a permanent way of repairing the foundation however there are few disadvantages. The difficulties in drilling in any residential area and also the cost involved for this process limits this method. There are lots of digging need to be done and lots of dirt also has to be removed and after that the clean-up process also needs quite a lot of time and effort.

  • High-density polyurethane foam

This is another new method which has been recently developed and has become quite popular in the market because of its speed of repair and the price that need to be spend. Slab repair has become quite simple by using such high-density polyurethane foam.

Here the repair technician will inject the polyurethane foam inside the checkerboard grid which can be about six feet on the center of the area which is affected. However, while implementing this process one has to be careful about the HVAC ducts that may be running under the floor and foam may often clog them. Also, before undertaking the job, plumbing testing is necessary to check for any leakages in the drain or supply lines.
