Polypropylene is a very flexible geomembrane can come in either PP (polypropylene) or RPP (reinforced polypropylene). The main difference being that RPP has a reinforced polyester scrim encapsulated by polypropylene. The polyester scrim makes RPP very strong and is the perfect material for floating covers, where the material will rise and fall with the level of fluid under the cover. Another notable difference that separates RPP from HDPE is the thermal properties in the RPP don’t expand and contract as they do in HDPE.
As polypropylene is very flexible it makes for the perfect material to pre-fabricate small liners out of. These liners can be made to order in the factory and freighted out to customers.
Geoline has pre-fabricated liners for popular obstacle course races such as Tough Mudder where the liners were required to be sent out to courses in Australia and New Zealand with a low on-site installation presence. Welding of thin Polypropylene is best kept to factory conditions away from the weather elements.
Geoline has worked on numerous polypropylene geomembrane installations including liners and floating covers.
