Description

 

Root-resistant bitumen sheet for roofing is a modified bitumen membrane consisting of Styrene-Butadiene-Styrene (SBS)modified asphalt mixed with imported chemical root inhibitor, reinforced with polyester fiber, and covered with different upper isolation materials. Waterproof membranes, surfaced with four different upper materials, are therefore divided into three types: PE film surfacing, Sand surfacing , Mineral surfacing.

 

Where to use

 

Ø  Green roofs

Ø  Top plate of afforested areas

 

 

Advantages

Have double functions: waterproofness and anti-penetration

Causing no damage to the normal growth of plants

It will be a high-strength membrane to resist water

Penetration-resisting, wear-resisting, tear-resisting, corrosion-resisting, mould-resisting and weather-resisting

Good tensile strength and elongation

Strong adaptability to shrinkage, deformation and cracks of substrate

Resistant to both high temperature and low temperature

Attention

Root-resistant bitumen sheet for roofing should be stored in well-ventilated place and avoid being exposed to the sun or rain. The temperature in stored places can not be higher than 50° C. The bitumen sheet cannot be piled up.

 

Application System

Dongsheng plant waterproof system includes vegetable layer, soil, filter and aquifer, drainage layer, protection layer, ARC membrane waterproof layer, normal SBS membrane waterproof layer, leveling course, slope making layer, isolation layer and structural slab.

 

Application Method

u  Surface preparation-----Surfaces should be dry, clean, smooth and free from any dusts, oil or loose particles. Cracks and surface irregularities need to be filled by polymer mortar.

 

u  Priming-----Before membrane laying, substrate treating agent need to be brushed evenly and completely cover all laying places.

u  Membrane laying-----For adhesion between membrane and substrate or membranes, it can use hot melt method or cold adhesion method. According to application designs and specific applied parts, it can be applied by fully adhesion method, strip adhesion method and border adhesion method.

 

u  Sealing, fixing and constraining on vertical surfaces-----On vertical surfaces, fix with metal battens and seal with sealants for membranes.

 

u  Application on protection and isolation layer-----After membrane laying, construct protection and isolation layer according to waterproof layer design.
