DELTA®-DRAIN 9000 is a high-performance, high-strength drainboard ideally suited for demanding horizontal drainage applications in plaza deck and pavement construction, and split slabs where high compressive strength and high flow rates are required.
High water flow rate and ultimate compressive strength characterize this commercial grade drainboard. Its high-strength Polypropylene core provides a continuous path for water discharge. The woven monofilament fabric allows water to pass freely into the drainage core while withstanding abrasion during substrate application (i.e. gravel). The high-strength monofilaments in this type fabric prevent intrusion of overburden material into the drainage core to maintain its high transmissivity.
DELTA®-DRAIN 9000 is the ideal solution for horizontal applications like plaza deck and pavement construction, split slabs, etc. where a combination of high compressive strength and high-drainage capacity is required. Whether in commercial or civil engineering applications, this drainboard has proven superior long term performance in regards to water flow rate, compressive strength, and chemical and environmental stress crack resistance.
