Paraseal STD

Paraseal STD is a robust sheet waterproofing membrane that combines 15 mils of HDPE with expandable, granular bentonite, forming a dual-layer waterproofing system. Each square foot of this composite material weighs up to 1.0 lb, ensuring substantial protection.

Paraseal STD is primarily designed for use on backfilled walls and can be applied to damp or green concrete. It’s also available in variants tailored for specific conditions like lagging, split slab, under slab, and methane barriers, making it adaptable to a broad range of construction needs.

– Rapid Installation: Suitable for green or damp surfaces, facilitating faster construction schedules.

– Dual Waterproofing Action: Features a bentonite layer that can expand up to eight times its thickness, providing an exceptional secondary barrier against water intrusion.

– Versatile Application: Effective in diverse installation environments, including challenging soil conditions.

– Confinement Requirements: Needs a minimum of 24 psf of compaction or confinement.

– Environmental Restrictions: Should not be installed over standing water, snow, or in continuously submerged conditions.

– Material Compatibility: If backfill is abrasive or contains materials like lava rock, additional protection may be required.

– Water Quality Consideration: In cases of brackish groundwater, specific bentonite formulations may be necessary, and consultation with Tremco’s technical services is advised.

Paraseal STD is an ideal solution for projects requiring reliable waterproofing under various environmental and soil conditions, ensuring long-lasting protection with its innovative HDPE and bentonite composition.
