Concrete Caulking
It is important to remember that your concrete sunk for a reason and we can help diagnose and repair that issue as well. Many times improper run off or drainage can allow water to settle and seep into your concrete at the joints. This can allow for soil erosion and water penetration below the slab which when freeze thaw cycle occur the concrete can sink or heave.
Other times the slabs of concrete were installed in a way that diverts water incorrectly and lifting the concrete on one side can divert the water in the desired direction.
Once we have lifted the concrete we provide a service to caulk the joints of the lifted slab to keep the moisture out. For your warranty to be valid the joints surrounding the slab we raised must be caulked. This will cut down significantly on settling and erosion issues and help prevent further soil loss.
