Made of polyethylene?
Lawn Belt is made from a combination of both polyethylene and plastic resins. It's an extremely durable yet flexible conduit.
If the sprinkler system is accidentally punctured it can be repaired easily. Simply locate the leak and install a coupler kit within a few minutes.
A big advantage having our in-ground sprinkler system is ... that it sits just inches below the grade. A surface level system like Lawn Belt allows you to find and repair leaks very easily.
