LiquiTEC Roof and Terrace System

The Bauder LiquiTEC roof system is a fast-curing poly methyl methacrylate (PMMA) resin system reinforced with polyester fleece.

LiquiDEK Roof System achieves a CCPI mark which recognises that any claims made about it have been independently assessed across 11 clauses, providing greater clarity by offering improved product information. This gives specifiers confidence in the knowledge that they will have unambiguous information when deciding which of our systems is best for their new build or refurbishment project.

When to specify...

LiquiTEC is a fast-curing, two-coat, wet-on-wet system particularly suited to areas where there is a high degree of detailing, or when access to install waterproofing is restricted. The system is appropriate for both new build or refurbishment applications for cold, warm, and inverted roof constructions. 

The system can be used as exposed roof waterproofing or as a roof terrace when protected by hard landscaping as well as extensive and intensive green roof systems. The system can be used in zero falls applications in protected roof situations.
