Waterproofing tapes
Butyl sealing tape for membrane seams and building details. Compare five size and reinforcement combinations, including aluminium, fabric and fabric with EPDM.
A flexible butyl rubber adhesive layer bonds and seals membrane seams and building details. Select the tape, primer and joint arrangement for the intended application.
A peel-off release film protects the self-adhesive layer before placement. Apply to compatible, primed contact surfaces and press firmly with a hand roller.
Choose from no reinforcement, aluminium foil, aluminium sheet, fabric, or fabric with EPDM. Custom dimensions and reinforcement options are available, with specification and supply terms confirmed for the order.

Order by the full SKU. The dimensions are nominal; each SKU identifies one size and reinforcement combination.
| SKU | Reinforcement | Width | Roll length | Nominal thickness |
|---|---|---|---|---|
| WP-TAP-000002-001 | None | 40 mm | 20 m | 1.5 mm |
| WP-TAP-000002-002 | Aluminium foil | 150 mm | 10 m | 1.2 mm |
| WP-TAP-000002-003 | Aluminium sheet | 150 mm | 10 m | 1.2 mm |
| WP-TAP-000002-004 | Fabric | 250 mm | 10 m | 0.7 mm |
| WP-TAP-000002-005 | Fabric + EPDM | 150 mm | 10 m | 1.2 mm |
For custom dimensions or reinforcement, send your required construction and tolerances. We will review the available combination and performance requirements.
Confirm the selected variant and primer for your substrate and surface coating. Include joint movement, outdoor exposure or water contact in the review.
Agree primer coverage and drying time, tape coverage, overlaps and terminations for the joint. Check the component combination before using the tape with the related EPDM membranes.
TDS Rev.01 reports these JC/T 942-2004 results for a nominal 40 mm × 20 m × 1.5 mm specimen. Its connection to SKU 001 is based on size alone: matching backing, reinforcement and formulation remain unconfirmed. These results do not establish performance for a supplied SKU, other variants or custom sizes, and are not guaranteed production limits.

Butyl self-adhesive sealing tape: technical data sheet
WP-TAP-000002: five SKU options and JC/T 942-2004 specimen results. The specimen matches SKU 001 by nominal size only; the results do not establish performance for a supplied SKU or define service temperature limits.
The product range includes uses on EPDM, metal, concrete, stone, wood, plastics and glass. Ask us to check your exact surface, coating and tape variant, especially for exposed or water-contact joints.
Yes. Use a compatible primer and a hand roller. Confirm surface preparation, drying time and tape coverage for the selected joint.
No. The tested specimen matches SKU 001 by nominal size only. Its backing, reinforcement and formulation have not been matched to that SKU. Request performance confirmation for the SKU you intend to order.
Yes. Include your required storage period, installation temperatures and expected exposure with the inquiry. Ask for applicable shelf-life and warranty terms; laboratory temperatures do not define a service range.
Waterproofing membranes
Non-self-adhesive EPDM membrane for roofs, basements and pond lining. Choose from five thicknesses in 1.2 m × 20 m rolls, or request custom dimensions.
Waterproofing membranes
EPDM membrane with a reactive butyl adhesive backing and removable release film. Four nominal thicknesses in 1.2 m × 20 m rolls for use on compatible concrete, mortar and metal surfaces.
