Seco Ground

A below-ground Radon gas and mold prevention system for new homes.

Modern Solutions For Homes

Seco Ground is a Radon gas and mold prevention solution for new homes. It is installed during the construction of your home, in the gravel beneath your basement.

The system removes the air within the gravel and exhausts it to the outdoors. That evacuated air contains the moisture and Radon gas which can seep into your home.

Seco Ground consists of a series of perforated pipes that are connected throughout the gravel. These pipes are controlled by a Seco Air Handler which regularly removes air from the gravel and exhausts it to the outside.

All homes are susceptible to Radon gas and mold produced by excess moisture. Seco Ground is the best solution for providing long-term protection for you and your family.

The Basics

  • Prevents dangerous radon gas from entering your home.
  • Prevents mold growth through moisture control.
  • Removes excess moisture from within the gravel, eliminating the musty smell common to basements.
  • Installed below the concrete basement floor or in the gravel of a crawl space.
  • Can be installed in homes with or without basements.
  • Creates a more stable soil environment, reducing the risk of floor-heaving caused by fluctuations in soil conditions.

Seco Air Handler

The Seco Air Handler is the heart of the Seco Ground system. It controls the air being pulled through the pipes and sent to the outdoors.


Mold and Moisture

Mold in your home grows as a result of excess moisture commonly found in basements. The best solution is to control the humidity and prevent the mold from growing.

Exposure to mold can have negative health effects including coughing, sneezing, and congestion, while also impacting other respiratory problems such as asthma.

Seco Ground actively controls the moisture level beneath your home, drawing away excess moisture, preventing mold from growing.

Radon Gas

Radon gas is a colourless, odourless radioactive gas produced in the environment through the breakdown of the uranium in the soil and rocks. It enters the home through basement walls and floors.

Long-term exposure to high levels of radon in the home may increase the risk of developing lung cancer.

Seco Ground removes the radon gas beneath your basement and safely vents it to the outdoors, preventing it from entering your home.



Floor heaving is the result of the expansion and contraction of the soil beneath your home, which pushes up on the concrete and causes it to crack.

Floor heaving can be caused by many factors, but one of the primary contributors is excess moisture in the soil.

The process of building a home dramatically disturbs the soil beneath it. Regardless of the quality of the home being built, floor heaving is a realistic problem that can occur.

Seco Ground reduces the moisture levels beneath your home, which helps to prevent floor heaving.


Seco Ground must be installed in the gravel beneath the home. This can happen below the concrete slab or in the gravel of a crawl space.
A series of flexible perforated pipes are strategically embedded in the gravel that exists beneath your basement. These pipes spread out to cover the entire base of your home, creating a network of air channels.

  • An exhaust shaft is attached to the pipes to provide a central access point above ground.
  • The basement floor is installed by the home builder.
  • The Seco Air Handler is connected to the exhaust shaft, controlling the air within the gravel.

The installation is now complete.
