Pressed pilings with the help of concrete:

Fixing sinkholes is a significant problem nowadays. Concrete pressed pilings are used for fixing sinkholes.

In this process, large concrete cylinders are set in the ground, acting as the concrete piers. Concrete pressed pilling is good in providing support to the foundation. Adding more into its feature is that it is cost-effective and easy to proceed with.

However, concrete pressed piling is not so good in providing central point support. To recover this drawback, many construction companies use steel pressed pilings and concrete pressed piling to not move beside its point in harsh conditions.

As already stated earlier, it is a cost-effective foundation repair method, but it comes with another processing cost. Only a few types of soil allow the pressing of the concrete pillars. These concrete pillars are considered the sinkhole solution because they can be repaired by supporting the heights and sinkholes.

In some conditions, it is less favored because, due to the faulty pressing, these concrete cylinders may be cracked and bring no support.
