A double polyethylene hose
injected in the hollow space with cement; this
is the system, well-known all over the world,
for the structural relining of big pipelines
or underground canalizations.
It is a simple intuitive system, between building
structure and relining, using technological
materials easy to be worked.
The two polyethylene hoses are towed inside
the piping through a winch. Between the two
coupled hoses there is a thick riveting forming
a perfectly gauged hollow space where a special
cement mortar is injected. Hardening takes
place in a few hours without heating.
This system is studied for any manifold geometry
and can also use any stiffening metallic reinforcement.
