Self-adhesive membrane waterproofing

Self-adhesive membrane is a cold applied self-adhesive sheet membrane corrprising of a polymer modified bitumen layer internally reinforced with polyester, bonded on to an outer surface of cross laminated polyethylene film The polymer bitumen adhesive layer is protected on the underside by a silicone release paper which is removed just prior to the application of self-adhesive membrane to the tack coat primed substrate. The applied membrane is then immediately protected from UV light and from mechanical damage during subsequent back filling by the application of Protection Board, or a sand/ cement screed.

Areas of use:

Self adhesive is an ideal membrane for darrp-proofing, foundations, below grade walls, bridges, viaducts, tunnels, concrete and polystyrene substrates, decks and balconies, beneath shower pans and in split slab Constructions.

Liquid membrane waterproofing

Liquid membrane is one or two corrponent biturrinous rubber emulsion with special hydraulically hardening fillers.

Areas of use:

Liquid waterproofing is an ideal membrane for Internal wet areas, below tile waterproofing, decks and balconies, podiums, trafficable decks, pipe entries.

Cementitious waterproofing

Flexible cementitious waterproofing membranes corrprise a mix of dry cement and sand, and liquid latex. The materials are mixed on construction sites resulting in a relatively thin, cementitious liquid that can be applied by brush or roller onto different substrates.

Areas of use:

Cementitious waterproofing system is designed for waterproofing concrete against water pressure in wide variety of structures such as; sewage treatment and water treatment plants, water tanks, concrete pipes, manholes, potable water retaining structures, internal basement waterproofing and drainage culverts.

Torch applied bituminous waterproofing

Bitumen technology has proven by far to be the most reliable technology in the waterproofing industry. Bitumen membranes are rubberized asphalt, modified plastomer or elastomer bitumen. Most waterproofing membranes are made with $85 modified bitumen and include a re-enforcement of non-woven polyester or glass mat.

Areas of use:

Torch applied membranes are mostly used for underground waterproofing, retaining walls, foundations and basements, roofs, tunnels and underground structures.
