We specialize in the research of waterproofing, leak-mending, reinforced and insulating technology in building industry, and supply a full range of products, like the most advanced waterproof polymer materials.
Our products have been systematized, diversified and professionalized. Accredited by exports, the waterproof thermal insulation compound materials of on-site polyurethane spray foams has reached the advanced international standard of the 1990s.
We adhere to the tenet of Quality first, Credit uppermost, Service best to serve our clients. Water controlling of Dayu spirit is our success belief, water holding is our sincere commitment.

We mainly produce two kinds of membranes by torching or self-adhesive.
For torching -on APP/SBS modified bitumen waterproofing membrane, it has good ability of anti-aging, anti-alkali, resistant to low temperature. High tensile strength and enlongation, which adapts to the contraction or crack of the base .,and can be used
1, Basement and roofing of key waterproof engineering, general and civil engineering .
2, Bridge , road, granary, tunnel, park ,swimming pool, sewage purifying pool and others.
3, Especially adapting to the waterproof of structure changeable and cold or hot area.

The other is by self-adhesive roofing membrane, the structure are as follow:
PET isolation film
2.self-adhesive bitumen rubber
3.SBS/APP modified bitumen.
4.polyestor or fibreglass reinforcement
5.SBS/APP modified bitumen.
6.self-adhesive bitumen rubber
7..PET or PE film or aluminium film It an be widely used in waterproof works on industry or civil 's roofing, basement, tunnel ,the metal roofing , roofing greening and other waterproof projects.
Advantages are as follow.
1.High tensile strength and elongation which adapts to contraction or crack of the base.
2.Excellent adhesive property and able to be applied in dampening surface, and good ability to resist the water break though.
3.Good acid, alkali and other chemical substances resistance.
4.High self-cure ability and extensibility
5.Easy operation and increasing working-efficiency to save expenses.
6.Nontoxic, flavourless , meeting the environmental requirements.
