• Suction Point
    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.
  • Suction Point
    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.
  • Radon-System-Suction-Point-Good-Gravel
    Suction Point
    Underneath the basement slab we found excellent 5/8″ pea gravel which helps to have a very successful radon system. We get excited when we see the good stuff, this rarely happens.
  • Suction-Point-Depth
    Suction Point
    The depth of the hole that we have dug to improve the PFE and provide the safest radon levels.
  • Suction Point
    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.
  • Suction Point
    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 underneath the concrete crawl space floor.
  • Suction Point
    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.

    This is a picture of how your system will look with a suction point in the garage with the fan located in the attic of the garage. The “T” is positioned to direct the suction to additional areas, such as the basement.
  • Suction Point
    This suction point goes into the home’s drain tile system, allowing the radon system and water management system to work perfectly together.
  • Suction Point in Finished Basement
    Suction Point
    We prefer to locate the suction point in the unfinished part of the basement. This home had a 100% finished basement so the decision was made to choose the least affected area: a closet or small storage area.
  • Radon-System-Suction-Point-Finished-Basement
    Suction Point
    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.
  • Radon-mitigation-gate-valve
    Suction Point
    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.

  • Radon System Interior Pipe
    Suction Point
    The suction pipe is incorporated into the shelf to save space inside the basement.
  • Radon-System-Finished-Basement
    Suction Point
    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.
  • Suction Point
    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.
  • Suction Point
    This is the IEMA sticker that must be placed on all radon mitigation systems. The number is like a license plate for a car but is a license plate for your radon mitigation system.
  • Radon System Suction Point Poor Soil Conditions

    This photo shows poor soil conditions (sand and compacted soil) that could potentially affect the success of the system as well as increase the number of suction points that this home will require.
  • Suction-Point-Poor-Soil
    Suction Point
    The material that was found under the basement slab did not meet the minimum requirements. The material that is the best is dry pea gravel 4” to 6” depth. Too much gravel of more than 4” can also increase the risk of bigger size pipe and larger fan.
  • radiant heat,radon mitigation,Suction Point,thermal imaging,thermal imaging camera
    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.
  • Radon Mitigation Using Ground Penetrating Radar GPR to Locate Buried Utilities
    gpr,ground penetrating radar,radon mitigation,Suction Point
    Ground Penetrating Radar (GPR) is used to protect the sale and keep money in the pocket of the seller or building owner. GPR identifies buried electrical, plumbing, footings, and foundation. This is one of the most important steps prior to conducting Pressure Field Extension (PFE) tests because it identifies safe areas to drill. Many “Poke and Hope” mitigation companies are risk-takers and do not discuss this process. Their luck will eventually run out and you better hope it is not at your house or building.
  • Radon-suction-point-concrete-scanning
    Suction Point
    When concrete scanning is worth the price five times over. In this situation, the mechanical, wastewater, water supply, and HVAC ducts are all in the slab. Scanning the floor identified a safe area for us to drill.
  • Concrete-scanning
    Suction Point
    We utilize concrete scanning and thermal imaging to identify the structural cable and radiant heat lines. Why is this important? If a structural cable is damaged it can damage the structure. Protecting the radiant heat lines will prevent thousands of dollars of repair costs.
