Product Overview
Description
Root penetration resistance roofing sheet price competitive
ARC-701 is a modified bitumen base sheet consisting of Styrene-Butadiene-Styrene (SBS)modifiedasphalt added with imported chemical root inhibitor, reinforced with polyester fiber, covering different upper separated materials. According to different upper surface, it includes three types: PE film surfacing (ARC-701PE), Sand surfacing (ARC-701S) and Mineral surfacing ARC-701M). There have two kinds of thickness: 4 mm and 5 mm.
Green roofs;
Top plate of afforested areas;
Have a double functions of waterproofness and penetration;
Not affect 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 for substrate shrinkage, deformation and cracks;
Both high and low temperature resistance.
Q/SY YHF 016-2009 and JC/T 1075-2008.

Above quantities are indicative only.
ARC-701 material 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. It only can be put vertically in single-level.
In order to prevent inclination or lateral drift, ARC-701 material can not be put vertically in double-level.
Application System
Yuhong 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
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.
Priming
Before membrane laying, substrate treating agent need to be brushed evenly and completely cover all laying places.
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 adhered method, strip adhered method and border adhered method.
Sealing, fixing and constraining on vertical surfaces
On vertical surfaces, fix with metal battens and seal with sealants for membranes.
Application on protection and isolation layer
After membrane laying, apply on protection and isolation layer according to waterproof layer design.
