Undersealing and Voidfill
One of the biggest causes of foundation issues or soil degradation is moving water.
High water tables or poor drainage of water runoff can cause soil to move away from areas where weight is compressing on the soil. High water tables can buoy the structure and cause the structure to leak water into the building.
Ground Works Solutions utilizes the patented URETEK polymers, which are hydro-insensitive, meaning the product will displace water from an area and will not degrade due to moving water. If you are experiencing a problem with soil movement caused by water or have a leaking structure that requires sealing, this process is the right solution for you.
