Residential Retrofit Basement Sub-Slab

A typical radon venting pipe from a sub-slab environment. The riser piping is labeled with the company logo sticker and a warning sticker indicating that the pipe is a critical component of the radon system.

The riser is supported by a metal strap as it rises vertically and again, against the ceiling as the pipe runs along that part of the structure.

   Crawlspace

Crawlspaces require a layer of plastic, laid over the top of the crawlspace dirt or gravel flooring. The plastic is thoroughly sealed and the radon containing air is drawn from under the plastic and piped to the exterior of the structure.

   Radon Pipe Installed in the Closet

Radon systems piping may be routed through the garage, if necessary.

   Fire Collars in the Garage

Protection from fire is critical. When the radon system piping must penetrate a fire rated wall or a fire rated ceiling, a fire collar is used to maintain the fire rating.

This photo is an example of a vacuum pump installed within an attic cavity. A vacuum pump is a common piece of equipment for all radon mitigation systems. The actual placement location of the pump may vary but it is always placed to be as inconspicuous as possible.

Exterior Systems

An exterior installation of the vacuum pump is our preferred installation method. If there should be a vacuum pump failure, we can make repairs from the exterior, without the client needing to be at the property. An exterior mounted system also requires less labor and material to install than an attic mounted vacuum pump, allowing us to keep the job cost at a minimum. We attempt to conceal the radon system behind shrubs or place it in the same area as other mechanicals such as the air conditioner compressor or electrical components.
