Radon Mitigation Core Drilling

Radon mitigation systems require one or more holes drilled through the basement floor slab to allow a depressurization pipe to draw radon gas from beneath the concrete and vent it safely above the roofline. REDCORE provides core drilling services for radon mitigation installers and homeowners throughout Massachusetts, creating clean, precisely sized penetrations through basement floor slabs for sub-slab depressurization systems. The standard penetration for a radon system is a 4-inch or 5-inch diameter core hole, drilled through the slab and into the aggregate or soil below.

Proper radon system core drilling requires more than just punching a hole through the slab. The hole must be positioned in the location specified by the radon mitigation design, typically in an area with good sub-slab air communication. The core must be drilled cleanly without cracking the surrounding slab, and the sub-slab material must be excavated to create a small suction pit beneath the pipe. REDCORE drills clean, round holes that provide airtight pipe sealing and optimal system performance.

We also drill penetrations through rim joists and foundation walls for routing the radon exhaust pipe to the exterior of the building. Our core drilling equipment handles any material encountered in residential construction, from standard 4-inch basement slabs to thick foundation walls. Many radon mitigation companies throughout Massachusetts rely on REDCORE for their concrete penetration needs.
