Triton Bentofix BFG 5000

A waterproofing membrane for use over horizontal or vertical surfaces, to waterproof and protect reinforced concrete slabs and retaining structures.

The membrane sheet is a composite of sodium bentonite powder, a woven polypropylene geotextile on the underside and a non-woven polypropylene fibre layer on the topside (facing the concrete to be waterproofed).

The upper, non-woven layer has been impregnated with an additional loading of bentonite powder. The two geotextiles are mechanically joined by a needle punching process, pushing the fibres of the upper non-woven geotextile through the bentonite and securing them in the retaining lower layer.

The non-woven geotextile side is generally placed against the concrete structure, either in a pre or post applied application.

Features and benefits:

• Impermeable lap joints are achieved from the additional bentonite powder.

• Full surface contact between the bentonite impregnated cover layer and the concrete ensures that small cracks and surface imperfections are sealed.

• The membrane is heat sealed to securely link the two layers and to contain the bentonite.

• Self-healing properties.

• Quick and easy installation in most weather conditions.

• Forms a mechanical bond to poured concrete when cast in-situ (pre-applied application), remaining in place if settlement of the substrate occurs.

• No requirement for priming systems, joint taping or protection systems.

• Non-flammable.

• Tested in accordance with the appropriate parts of the following standards: ASTM D5887, CSN 73 0601 and ISO 10913.

Applications:

• Waterproofing protection to grades 1, 2 and 3 of BS 8102: 2009.

• Provides protection in either post-applied or pre-applied situations.

• Horizontal or vertical application.

• RC and masonry walls.

• Service reservoirs.

For situations where ground gases are also of concern, Bentofix BFG 5300 is available. Consult manufacturer for details.
