Core Drilling

Core drilling is used to create precise holes in concrete slabs or walls for the installation of radon mitigation system piping. This process ensures a clean, professional appearance and minimizes damage to the surrounding structure. Proper core drilling is essential for effective system performance and long-term durability.

Whenever possible, we core drill the penetration point for a neat finish between the concrete floor and the schedule 40 PVC piping. In most cases these holes are cut between 4 and 5 inches in diameter.

There are homes where core drilling is not the most appropriate answer to entering the sub slab area, in these cases consideration is given to assure a professional finish around the suction point.

We create a bell shaped suction pit beneath the slab to expand the pressure field and increase the direction and range of air movement under the slab area. Approximately 5 to 10 gallons of material is excavated from under the slab.
