We perform diagnostic testing as part of your system design, We drill a few small holes in your basement floor. Into one hole we puff smoke (shown), into another hole across the basement we insert a vacuum. If the suction draws the smoke down into the hole, we know the system location will be successful and efficient.

We will core a neat 3 1/2″ to 5″ diameter hole into the basement floor (lowest slab) in an unfinished area. We will create a void space of at least 216 cubic inches to make the system efficient. While drilling we utilize the best HEPA filter technology to minimize concrete dust being released into the air.

We will caulk the suction pipe so that it remains airtight. We also properly secure and support the suction point by installing a coupling at the base of the suction point. This will allow the system to properly collect the radon from the suction point for the life of the system. All of our piping is Schedule 40 PVC. We use professional-grade caulk.

This photo shows a suction point installed in the concrete crawl space and an additional suction point going under the garage slab. Installing a garage slab suction point will collect the radon gas that is remaining through the foundation wall into your basement. A garage slab suction point will get the radon levels as low as possible, which is Elliott and Associates’ specialty.

The location of this suction in the finished basement allows the owner to enclose the pipe with drywall and not disrupt the capability of storage in the crawl space. Creative solutions to installing the system to minimize impact on finished basement are our specialty. This procedure also took into account the limited budget of the owner. Another option would be to cut the wall open and trench the basement floor so that the entire suction point would be hidden.

Gate valves are manipulated to increase the control of radon at other suction points, and to decrease the need for unnecessary suction points. Other benefits are a decrease in noise, airflow, more energy efficient, and longer-lasting fans. This process does require an experienced diagnostician, but safety is our ultimate goal.

This suction point was installed inside the walls before the basement was finished in order to keep the radon system hidden. Here’s another example of why there is no substitute for experience. This client gets the system that is totally incorporated into the wall and has NO obstruction into the finished area.

This is a picture of a test that confirms that the radon system is covering a specific area. Before and after the radon system is installed, a pressure field extension test is performed. The data helps to design the most efficient system and eliminates the “poke and hope method”. Yes, it does take extra time, but the safety of the family and the sale of the building depends on us installing the right system.

We protect your radiant heat system. Radiant heat consists of embedded coils in the cement floor that heat the floor. When we drill our suction point into your cement floor, we do not want to damage your buried systems! We have the ability to identify the location of your radiant heat system prior to drilling into the cement. This photo shows what we see when we use our thermal imaging camera to identify a radiant heat system. Call us for details.
