Polymeric Waterproofing Membrane

Bengal Aquaflex is heavy duty APP (Atactic Polypropylene) modified polymeric waterproofing membrane manufactured to high standards. It is a five- layered membrane with a centre core of 100 micron. HMHDPE.

The centre core reinforcement protects against water and moisture and makes it totally impermeable. The centre core is coated on both sides with high quality polymeric bitumen with properties of high softening point, high heat resistance and cold resistivity. This makes it ideal for even heavy duty 'Waterproofing treatments'. The polymeric bitumen on both sides of the centre core is protected on both sides with thermofusible HMHDPE film. The finished membrane has an elongation of over 300 percent to absorb all structural movements.

Main Features

Good dimensional stability
Enhanced resistance to chemicals
Elongation exceeding 300 percent to absorb all structural movements
High tensile strength and cold flexibility

BENGAL AQUAFLEX WITH Aluminium Top (ALT)

Bengal Aquaflex is also available with 75 micron thick Aluminium foil on top. The Aluminium Top provides protection from UV rays, delays ageing and prevents disintegration of bitumen.

USES

Aquaflex is ideal for rooftops, basements and terrace gardens. It meets CPWD Specifications.

Method of Application

Clean the surface to make it smooth.
Apply a coat of Bengal Primer @ 0.3 liters per sqm on the clean surface.
This should be followed by a coat of hot applied Bengal Bitumen 85/25 @ 1.2 kg per sqm
Lay and press Bengal Aquaflex on the hot bitumen.
A minimum overlap of 100 mm is recommended between the two rolls of membrane to be sealed with blown bitumen.
Bengal Aquaflex is to be topped with screed or tiles as the case may be.

Outstanding Features

High softening point and high penetration.
High elongation.
Flexibility at very low temperature.
