M-Mineral grains/slates
The products are made by soaking the base in bitumen. or thermoplasticity elastomer (such an styrene butadiene styrene--SBS),or thermoplastics(such as atactic Polypropylene---APP,APAO,APL)modified bitumen, then covering double faces with elastomer(SBS)or thermoplastics(APP,APAO,APL)modified bitumen, and last finishing the upward face with fine sands, mineral slates(or grains)or polythene membrane while downward face with fine sands or polythene membrane.
Feature: Good waterproofing dampproofing, ageing-resistance, leakproofing, no flowing at highest temperature and no crack lowest temperature, good self heating, easy application, and long service, etc.
