Boa-Tape™ is a pressure sensitive taping system designed to seal joints against ground water
infiltration, encapsulate manholes or vaults and protect pipelines. The 50 mil. elasticomeric mastic
in combination with 15 mils. of a woven polypropylene makes this tape extra-extra sticky.
Apply PSI Pressure Sensitive Primerless Boa-Tape on exterior concrete manholes or other structures at locations indicated by the Engineer to protect manhole and mitigate infiltration/exfiltration of water and other contaminates. Boa-Tape™ shall be applied over a dust-free, dry concrete surface. The Boa-Tape™ system shall be as manufactured by Pipeline Seal and Insulator, Inc, Houston, Texas to ISO 9001:2008 standards.
2.0 Tape - Woven Polypropylene Membrane with Elastomeric Adhesive
The pressure applied Boa-Tape™ shall consist of a 4 inch, 6 inch or 12 inch wide wrap-around tape system 65 mils. thick with a 15 mil. membrane and 50 mils. of integrated primer and elastomeric adhesive. Peel strength shall be a minimum of 12.5 lb./in., per ASTM D 1000. Tensile strength shall be 75 lbs/inch width. Mastic softening point shall meet or exceed 240 degrees F +/- 10 % in accordance with ASTM E-28. Water Absorption shall be less than .5% per ASTM D 570.

1. Clean all exterior surfaces of the manhole with a brush or broom
to remove any loose cement, dust or small rock particles.
2. Remove 8" (20cm) of release backing and position exposed tape surface on cleaned seam area.
Expose 8" (20cm) of tape at a time by pulling release backing away from mastic as tape is wrapped
around the entire circumference of the manhole, vault or pipe.
3. Carefully cut the Boa-Tape™ when applying over cast iron manhole gussets. Gently mold the tape around gussets with roller/gloved hand.
