RAMMED CAR TYRE FOUNDATIONS
Introduction:
As an example of a low-impact, environmentally
friendly building technique, it is hard to better the use
of recycled car tyres as foundation material. If not exposed
to ultra violet light via sunlight, their estimated life expectancy
is 30,000 years! Significantly longer than environmentally
high-impact concrete. They have been widely used, particularly
in the USA, to build whole houses, known as “earthships”.
The first earthships are now being built in England (near
Brighton) and Scotland (near Fife) with full Planning and
Building Regulation approval.
Most buildings need to have some sort of foundation on which
to build. This fulfils several functions:
- To provide a solid, stable base
that distributes the weight of whatever is built upon it
over the ground beneath.
- To raise the walls above ground
level, to protect them from groundwater and rain.
- By using a damp proof course within
the foundation, the walls can be protected from damp below
them
