Description of hdpe water stop:
HDPE water stop, also a kind of plastic water stop similar to PVC waterstop, are made of quality high density polyethylene materials with highchemical resistance when exposed to hydrocarbons, acids, hot petroleum oils, solvents and diesel fuels, etc. However, the HDPE waterstop is harder, more abrasion and heat resistant than PVC waterstops.
Features of hdpe water stop:
1.Strong and durable.
2.High resistance to elevate and low temperature.
3.Excellent anti-abrasion.
4.Superior resistance to chemical liquids, hydrocarbons, acids, solvents, oils, fuels, and other non-polar fluids, etc.
5.Resistant to oxidants and reducing agents.
6.Not prone to swell and be flexible.
7.Easy to butt-weld to form a continuous diaphragm.

Note:
1.Not recommended for applications in oxidizing acid circumstances, for example, nitric, chloro sulfonic and fuming sulfuric, etc.
2.Polyethylene will dissolve at high temperature in hydrocarbons and halogenated hydrocarbons such as toluene, xylene, or chlorinated solvents.
Applications of hdpe water stop:
1.Perfect for primary and secondary containment structure.
2.Sewage treatment facilities.
3.Fueling areas.
4.Mining and refineries facilities.
5.Chemical plants
6.Liner application
Installation of hdpe water stop:
In conjunction with brass eyelets, punched flanges or hog rings, tie wires to surrounding reinforcing bars to prevent the water stop from displacing during the concrete pour. For changing directions, pre-fabricated waterstops are recommended.
Package of hdpe waterstop:
Generally speaking, 20 or 25 meter per roll, plastic bag pack, then pallet delivery. Or according to your request.
