- Methane
gas can and has resulted in explosions and fire,
and steps must be taken to construct new
buildings on methane emitting
- ground
in a manner that controls this hazard and permits
- safe
discharge of the dangerous gas.
*******************************
Injecting
smoke underneath the membrane
Methane barrier systems prevent
the passage of gas, and it provides a
waterproofing system that prevents the
- passage
of liquid [water] under hydrostatic pressure.
*******************************
Membrane
starting to lift off the ground by injected
"smoke"
Methane barriers are
created across the property floors and walls, and
methane gas is prevented from accumulating within
the
- structure.
Any methane gas that rises is forced to
discharge
- via
pipes, which promote emission into the open air
- and
away from the building.

City Engineer
and Builder looking for possible leaks
-
Being
lighter than air, methane gas will rise to the
top of any enclosed space. However, when mixed
with other gases
- the
combination can in fact be heavier than air.
