Specially formulated, solvent resistant overbanding tape for Bituthene applications in chemically contaminated ground

Product Description

BITUTHENE® EDGEGUARD® Tape is a specially formulated tape designed for applications where resistance to hydrocarbon contaminated soil is required. BITUTHENE® EDGEGUARD® Tape is constructed of a 2 mil (0.05 mm) polyester film with a pressure sensitive, solvent resistant acrylic adhesive. The adhesive bond increases with age.

Product Advantages

  • Solvent resistant—protects BITUTHENE® compound from prolonged exposure to organic or fuel oils and solvents in the ground
  • System compatibility—engineered specifically for use with BITUTHENE® membranes
  • Self-adhered—easy to use; adhesive bond increases with age


BITUTHENE® EDGEGUARD® Tape is recommended for use over BITUTHENE® Membrane edges to protect the adhesive from prolonged exposure to hydrocarbon contaminated soil.

For guidelines on the use of BITUTHENE® Membranes in contaminated ground, please refer to Technical Letter 4, available at or contact GCP Technical Service.


On vertical and horizontal applications, place a continuous strip of tape centered on all membrane sides and end lap edges. Membrane surface must be clean and dry. In cooler temperatures, gently heat tape to enhance adhesion characteristics. Roll tape application with hand roller to maximize adhesion. Inspect application thoroughly, patch fishmouths with additional strips of tape as necessary to provide a tight seal.

Solvent Resistance Performance Test

BITUTHENE® EDGEGUARD® Tape is applied to an aluminum substrate 72 hours prior to a 72 hour immersion in the following environments: distilled water, lubricating oil, hydraulic oil, motor oil, diesel fuel, kerosene and mineral spirits. In all of the above environments the adhesion is 3 lbs/in. (53 N/100 mm).
