Description
The Geoworks Butyl Jointing Tape is a high-performance double-sided sealing tape designed for joining impermeable geomembranes, gas membranes, vapour barriers and damp proof membranes.
Manufactured from a professional-grade butyl mastic compound, the tape provides excellent adhesion to a wide range of construction materials whilst remaining flexible throughout its service life. The conformable nature of the tape allows it to create a reliable seal across membrane overlaps, helping maintain the integrity of waterproofing and containment systems.
Supplied in a convenient 50mm x 10m roll, it is easy to install with minimal waste, making it ideal for both civil engineering and construction applications.

What is butyl jointing tape used for?
Butyl jointing tape is used to seal overlaps between geomembranes, gas membranes, damp proof membranes and vapour barriers.
Can this tape be used with HDPE geomembranes?
Yes. It is commonly used for sealing overlaps in HDPE geomembrane installations.
Is the tape waterproof?
Yes. The butyl mastic construction creates a highly effective waterproof seal between membrane joints.
Does the tape remain flexible over time?
Yes. The tape remains flexible throughout its service life, helping maintain a reliable seal even with minor movement.
How much overlap can one roll seal?
A 10m roll will typically seal approximately 10 linear metres of membrane overlap.
