POLIBRID 706 may be applied onto almost any surface, offering a wider range of options in terminations and transitions from the geomembrane onto walls, tank bases, pads, pedestals and pipe racks. Fabric panels are overlapped at least 12", producing double-decked seams that greatly exceed the strength of the geomembrane itself. Reduces the need for mechanical anchoring and eliminates heat welding required for seams in thermoplastic sheet liners.
POLIBRID 706 is a premium-quality, thermosetting elastomer that meets all known VOC regulations and is virtually odorless during and after application. It is airless spray applied with specially designed plural component pumps at virtually any film thickness in one application. Its solventless formulation eliminates pinholes caused by solvent evaporation, producing a dense monolithic membrane that can be placed in immersion service moments after application.

- Recommended Uses
POLIBRID 706 is recommended for application over non-woven polypropylene geotextile fabrics to produce flexible geomembrane systems, typically installed over compacted soil. Also suitable for direct application to urethane foam, concrete or steel to protect against impact and abrasion.

- Mixing
Thoroughly mix Resin (Part A) with air-driven agitator for 30 minutes just prior to use. Black tint must be added to Catalyst (Part B), then thoroughly mixed with air-driven agitator for 30 minutes just prior to use.
- Geomembrane Installation
Soil Base: Prepare per Engineer's instructions to provide suitable foundation for geomembrane. Base must be dry with no weak or unstable areas, or abrupt grade changes. Base must be free of sticks, roots, debris and/or organic or decomposing matter. When applicable, excavate 24" wide x 36" deep trench (backfilled, compacted after geomembrane installation) to anchor geomembrane perimeter. Provide adequate drainage.
Fabric: Use heat-set, non-woven needlepunched polypropylene geotextile fabric (8 to 10 oz./yd.). Unroll and place flat upon soil base, allowing 12" overlap between adjacent panels. Cut panels as needed to accommodate penetrations, transitions, trenches, etc. Keep clean and dry, avoiding foot traffic on uncoated fabric.
Coating Application: Spray coating directly onto fabric, producing a monolithic membrane. At fabric overlaps, lift top lap and apply coating to bottom lap, then lay top lap back down and press it into the fresh coating using non-stick roller. Spray coating over top lap to produce an even, pinhole-free transition along entire overlap. To reduce field installation time, fabric panels may be pre-coated in-shop, moving them to job site as needed so that only seams and transitions are coated on-site.
NOTE: Transitions of the geomembrane to foundations, walls, piping, anchoring devices, etc. may require the use of specific primers, surface preparation methods and other procedures for the treatment of steel, concrete and other substrates.
