Description

SBS/APP modified bitumen waterproof membrane is made of bitumen modified with Styrene-Butadiene- Styrene (SBS) or Atactic-polypropylene as dipping and painting. Its upper surface covers PE membrane and color sand or schist, and lower surface is made of PE membrane or sand. Product types include normal SBS/APP, root resistance series, and mineral series.


Feature & Benefit

1. It has good waterproofing and aging-resistance function.

2. Not flowing in high temperature and no crack in low temperature.

3. It has long service life,etc. It is specially suitable to the high temperature area and strong sun-shining area.

4. All seasons can be constructed.

Main Application

It is widely used for the waterproof, damp-proof and seepage-proofing of roof, basement, tunnel, underground building, etc..


Application Guidance

Widespread paving membrane: On the treated substrate, leave the lap seam (100mm for both long and short sides) according to the width of the membrane. Make the snap line and pave the membrane according to the datum line. The paving should be even and straight. The size of the overlapping should be correct metered and no distorting

Using torch-applied full boding method. In the course of paving, firstly bond the initial edge strongly then execute the reciprocating heating by flame heater whose nozzle is kept 0.3-0.5m from the membrane and the substrate heated position. Do not keep the flame at the same place for long time, or else it will cause the felt exposed or peeling. The heating should be even. Avoid overheating and burning the membrane. Roll the membrane to pave till the membrane surface is black glossy and within tiny bubble (not big amounts of bubble). Arrange one personnel to implement the venting and firming procedures

Lap seam treatment: Use blowtorch to heat the top membrane's bottom and the bottom membrane's surface fully. Make sure the tight bonding of the asphalt between membranes. The melting asphalt will be extruded from the edge, forming 2-5mm width uniform asphalt stripe
