BITUPLUS E 4000 G

Description

SBS modified double reinforced waterproofing membrane

 

BITUPLUS EG is a range of high performance double reinforced SBS modified bituminous membrane for the waterproofing of concrete bridge decks and slabs and is designed to withstand high thermal shock while remaining dimensionally stable. BITUPLUS EG membranes are made from non-woven polyester and fiberglass mat, which are saturated and coated with a homogenous thermoplastic blend of Styrene Butadiene Styrene Polymer, distilled bitumen and stabilizers. The mixture is carefully produced under controlled conditions to ensure its stability at high temperatures.

Properties

  • Suitable for heavy-duty application. 
  • Excellent resistance to puncture. 
  • Exceptional dimensional stability under pressure. 
  • Extreme tolerance to thermal shock. 
  • Impermeable to water and vapor.

Step by step

The application procedure may vary slightly depending upon site conditions. However, given below are the general guidelines:

SURFACE PREPARATION

Clean the surface thoroughly of all loosely adhering particles. Sharp protrusions if any are to be removed. Dampness or dew settled on the concrete surface is to be removed and brought to a dry condition.

PRIMING

Apply a coat of POLYPRIME SB (Solvent based bitumen primer) on to a clean, dry and smooth surface. Refer primer data sheet for further details.

ALIGNMENT

Unroll and align BITUPLUS EG and re roll correctly before torching. Overlap should be a minimum of 100 mm.

TORCHING

Use gas burner to heat substrate and the underside of BITUPLUS EG. Embossing on the lower face of the membrane allows a fast and safe laying. When embossing disappears, after torching the membrane is ready to stick. Roll forward and press firmly against the substrate to bond.

SEALING

Heat both the overlaps and use round tipped trowel to seal the overlap. Excess compound should be smoothened and press into seam using hot trowel.

UP STAND

All angles and abutments should be sealed with extra care to ensure full bondage. Seal the edges well into the grooves and protect with POLYSEAL PS or equivalent polysulphide sealant.
