Suction Point: We will core a neat 3 1/3" 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 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 is a sub-slab ventilation system with the primary suction point neatly located in an unfinished corner of the basement and an additional suction point going through the foundation wall undearneath the concrete crawl space floor. |
This photo shows a suction point installed in the concrete crawl space and 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. |
A gravel crawl space will be sealed with a 6 ml plastic membrane. The plastic will be secured to the walls of the crawl space with wood furring strips and sealant. This photo shows a secondary suction point installed under the plastic in the crawl space. |
This is an additional suction point that goes under a slab-on-grade portion of the home. Additional areas of the home that should be covered by a radon system include: crawl spaces, garage slab, front porch slab, slab additions, upper slabs, etc. |
