Prelasti EPDM Single-Ply is ideal for flat or pitched roofs, or as a complete building envelope membrane. Lightweight, and with no hot works required, it is perfect for light load-bearing timber buildings. It can be cut and shaped to waterproof any complex structure.
Offsite prefabrication and the application of vulcanising technology in a controlled environment, ensures 100% joint integrity. The Prelasti membrane has proven durability for over 50 years and is the membrane of choice for a cost effective fast track option.
Made from EPDM and prefabricated by AAC Waterproofing in a controlled factory environment, Prelasti provides 100% joint integrity. Flexible, durable and environmentally friendly, Prelasti is backed by a 20-year guarantee and has a life expectancy of 50 years. AAC Waterproofing is the UK’s sole supplier of Prelasti.
Prelasti EPDM is engineered for offsite prefabrication. Assembled in a controlled environment, Prelasti provides 100% joint integrity and instant waterproofing cover for projects.
There are a number of benefits for building offsite and complements the Building Information Modelling (BIM) techniques.
Prelasti EPDM employs a specific bonding technology, called vulcanisation. Vulcanisation is a chemical process for converting rubber or related polymers into more durable materials via the addition of "curatives". These additives modify the polymer by forming crosslinks (bridges) between polymer chains.
This molecular bonding process gives Prelasti 100% joint integrity – in effect, almost as if there are no joins at all. Thanks to this cutting-edge technology, Prelasti is backed by a 20-year guarantee and has a life expectancy of 50 years – far longer than many comparable waterproofing solutions.
Offsite build for waterproof roofing has many advantages and benefits over creating the structure at the project site. Off-site build such as that used by AAC Waterproofing for Prelasti leads to:
