The goal on all MEI jobsites is to get that pesky radon is LOW AS POSSIBLE.

Our thought process for the design and construction of your system are normally based on the variables below:

  • Extraction Pits – The number of extraction (suction) pits. The location, size, depth, and number of suction pits plays an important role in further reducing the radon.

  • Fan – The fan design is crucial as some fans are designed for different scenarios. For example, we may find clayey soil underneath the slab, where a soil communication test shows inadequate air flow for your typical in-store purchased radon fan. Therefore, a fan designed for high suction / low flow, or high suction / high flow would be able to most effectively reduce the radon.

  • Soil Type – The soil type plays a large role on the design / installation of a radon system. Stiffer soils such as clay prohibit air flow in comparison to sandy soils or gravelly soil, where soil voids are large and air flow is adequate.

  • Pipe – Both the pipe diameter and length of pipe affect the air flow. The more pipe and pipe features, such as elbows – the more energy loss due to friction, which will affect system performance.
