What is app waterproofing membrane?

app waterproofing membrane -- Plastic modified asphalt waterproofing membrane (APP) is made of APP (Random Polypropylene) or APAO APO (Polyolefin Polymer) modified asphalt is used as the impregnation material, with high-quality polyester felt, fiberglass felt, as the base material, fine sand, mineral particles (flakes), and PE film as the covering material. It is a plastic modified asphalt waterproofing membrane refined by advanced technology.

What are the basic features of app waterproofing membrane?

▪ It has unique high-temperature resistance and good low-temperature flexibility, combining both.

▪ Good water resistance, strong wear and corrosion resistance, and wide applicability.

▪ Good elasticity, high elongation, and strong adaptability to grassroots deformation.

▪ Both hot melt method and cold adhesive method can be used for construction.

What is app waterproofing membrane used for?

▪ Generally used for waterproofing in industrial and civil buildings.

▪ Suitable for waterproofing of various underground engineering upstream surfaces.

▪ Waterproofing of municipal projects such as bridges, roads, parking lots, subways, and tunnels.

Technical Data Sheet

Plastic modified asphalt waterproofing membrane complies with GB18243-2008 standard, with main physical and mechanical properties

Construction technology

▪ Apply modified asphalt cold base oil on the base layer, and after drying, delineate the laying line of the waterproof membrane according to the established benchmark line of the waterproof membrane.

▪ Spread the waterproof membrane along the laying line on the base layer, cut according to the size, and then roll it up in the opposite direction of unfolding (naturally rolled up).

▪ During hot melt construction, align the flame spray gun (spray lamp or electric heating machine) with the adjusted temperature at a distance of about 150mm towards the interface of the waterproof roll base layer, and quickly bake the roll and base layer

When the adhesive on the edges of the roll material turns black and shiny, immediately roll it and use a rubber roller to randomly compact it to eliminate air.

▪ During cold adhesive construction, use a rubber scraper to scrape the adhesive full of half the width of the roll to be laid, then roll and stick the determined waterproof roll in parallel, and use a rubber roller to spread the roll while laying to eliminate the possibility of damage Air compaction.

Attention

▪ During hot melt construction, the treatment agent applied to the base layer must be dry for 4 hours (preferably non stick), and the roll laying operation can be carried out above it to avoid fire. The construction site should also be equipped with appropriate equipment Quantity of fire extinguishing equipment.

▪ During roof construction operations, construction personnel are not allowed to enter the site wearing spiked shoes and must wear safety belts with protective facilities around them.

▪ Pay attention to finished product protection. Non construction personnel are strictly prohibited from entering the construction site and must be concealed within the specified time.
