Core Drilling

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.

The first step to help ensure the safety of you and your family’s health and safety is to have your home tested for radon. At St. Louis Radon, our professional testers deploy the latest in computerized electronic real-time radon monitoring technology to provide you with a comprehensive report, including a complete visual graph of radon level data points as recorded over a 48-hour sampling period.

If testing indicates levels of radon that require action, our team of engineers and technicians will design and install a custom radon mitigation system to safely and effectively redirect radon and other soil gasses out of your home. We also take additional measures to seal and close other possible breaches in the foundation that could let soil gasses into the through cracks or drain tiles systems.

New Construction

With new home construction projects, it is crucial to determine the level of radon that may be present in the soil before the home is built. It’s also critical to have the new home retested for potential radon concentrations immediately following occupancy. We also highly recommend installing an Active Dampness Control System (ADC) with every new build.
