We are a registered mitigation contractor. We must comply with more than 125 regulations to install a system that will meet the requirements set forth by the EPA. Our company is a Maine Registered Air and Water Contractor; this means we are certified to test and mitigate for radon gas in both the air and water.
Maine Radon Solutions can fix your radon gas problem. We offer several different air systems to remove and reduce radon levels in your home or business.
Radon gas originates in the earth underneath your home or business and comes up through the ground through micro pores and cracks in the basement slab, then makes its way into the home.
Sub-slab depressurization is the most common and efficient system for mitigating radon. These systems work by removing the air from underneath the stab to create a pressure barrier. This pressurized barrier prevents any radon gas from entering your home or business.
This system first needs vapor barrier layer covering the soil.
Sub-slab depressurization systems will create negative pressure under the slab that prevents the gas beneath the soil from being brought into the building.
To install this type of system, pipes are inserted through the slab and routed to the outside of the building. A fan is placed on the pipes and then the exhaust is routed harmlessly above the building.
The fans will pull air from underneath the slab. Removing this air creates a suction under the slab that is greater than the suction from the building. This suction will prevent the radon from entering the building.
Treating a dirt floor basement or a crawlspace is very similar to this process – except Maine Radon Solutions utilizes a fire retardant plastic membrane to provide the barrier that is normally created by the slab.
Also called heat recovery ventilator (HRV) or air to air heat exchanger, this radon mitigation system uses air to air heat exchanges to ensure that the home has low radon levels and a low natural ventilation rate. Typically, air to air heat exchanges are used in limited situations or as a last resort. Applicable situations could include a finished basement with the slab poured directly on clay or a ledge, or a dirt floor basement.
This process requires installing an air to air heat exchanger. This device brings fresh air in from outside and exchanges it with the stale air inside. Typically these devices are box shaped with duct work leading to and from the outside of the building and from the space that is being treated. As the air streams pass each other, the heat from the outgoing air is transferred to the incoming air.
There are several factors that can affect the resulting radon air concentration. These factors can help us determine whether or not an air to air heat exchanger would be a good solution.
