Eliminates Radon Gas Problems
The Environmentally Friendly LEGALETT Heated Slab Foundation
Construction Technique is a Proven Effective Tool Against
Radon Gas! The LEGALETT System is Already Recognized
as the Radon-Proof Foundation of Choice in Europe .
The LEGALETT System, is a continuous radon barrier under
the dwelling for a number of reasons:
- There is no separation of footing / foundation and floor
- the slab is continuous throughout, and thus there is no
continuous crack around the perimeter for radon to leak
through.
- Elimination of cracks in the floor - since the slab is
7-8" thick, and has heavy mesh top and bottom, the
only cracks in the floor (ever) are simply very minor hairline
shrinkage cracks which don't extend through the slab - they
are only visible at the very surface. Thus the slab is a
uniform, complete air (and thus radon) barrier. This is
in stark contract with thinner slabs, which typically have
wide cracks in them, which are not airtight.
- Ease of sealing penetrations - since the concrete is
7-8" thick, there is lots of depth to properly seal
any penetrations to the air-tight slab, instead of hoping
that you are sealing to a thin, cracked slab.
- Elimination of dependence on an air barrier to provide
radon-proofing - since the slab itself is the air barrier,
you are not relying on an easily punctured plastic air barrier
to be the radon proofing - instead, you have a durable,
thick, permanent air barrier.
