Mapei cements a tough bond with Mapeproof FBT
Mapeproof FBT by Mapei is a pre-applied synthetic waterproofing membrane with a nonwoven fabric backing applied in full adhesion to protect structures below ground level . It is able to withstand up to 7 bars of pressure , and provides Radon and Methane protection .
Mapeproof FBT is applied underneath foundation slabs and against diaphragm , pile walls , sheet piling and other permanent retaining structures .
The waterproofing system is suitable for a range of applications including basements , garages , car parks , swimming pools , basins , storage tanks , underpasses and underground areas in general .
The fully-bonded waterproof sheet membrane system incorporates two Mapei adhesive tapes : Mapeproof FBT Tape , used to bond joints between the upper-facing side of adjacent membranes in the system , and Mapeproof SA Tape , for bonding joints between the lowerfacing sides of adjacent membranes .
With extreme flexibility , Mapeproof FBT is easy to install . The waterproofing membrane is cold-applied ( between + 5 ° C and + 35 ° C ), thus no heat or naked flames are required on site . Positioned before placing the steel reinforcement and pouring of the concrete , joints can be bonded on horizontal or vertical surfaces and shaped to follow the geometry of the substrate , ensuring a longstanding tough bond ; due to its bond , Mapeproof FBT prevents water from migrating laterally between the
foundation structure and the membrane , once concrete has been poured . It does not require a protective layer .
The certified Mapeproof FBT waterproofing system also consists of two double-sided adhesive tapes . Mapeproof Fix Tape is used to hold the waterproofing membrane in place during installation . Meanwhile , Mapeproof BA Tape , a waterproof synthetic tape , is used for treating fillet joints between horizontal and vertical surfaces , as well as those between adjacent vertical surfaces .
