Dr. Fixit Seal Tape 150MM — Heavy-Duty TPE Joint Sealing Strip for Waterproofing

Joints, corners, and wall-to-floor junctions are where roof leakage and wall seepage almost always start. Not the middle of the slab. Not the flat open surface. The joint. It's the one spot in any waterproofing system where two surfaces meet, movement happens, and the gap widens over time — and if it isn't treated specifically and correctly, no amount of coating over the top will hold the water out for long. Dr. Fixit Seal Tape 150MM is the proven waterproofing solution that experienced waterproofing contractors use to close that vulnerability permanently — before the rest of the system goes on.

It's a 150mm wide heavy-duty sealing strip built around a highly elastic thermoplastic elastomer (TPE) core bonded to an outer polyester non-woven fleece. That combination matters. The TPE core stretches up to 600% — meaning it moves with the structure through thermal expansion, settlement, and ongoing structural shifts without ever tearing or losing its seal. Most joint treatments crack under that kind of movement. This one doesn't even notice it.

The outer fleece layer is what makes it genuinely compatible with the rest of your waterproofing chemicals system. Liquid waterproofing membranes, epoxy adhesives, and tile mortars all grip directly into the fleece fabric — creating a permanent mechanical bond that keeps the tape locked in place under continuous water pressure and high hydrostatic stress. No additional anchors, no complex mechanical fixing. You embed it directly into a wet coat of liquid waterproofing and it becomes part of the system.

Resistant to UV light, ozone, aggressive chemicals, salts, mild acids, and extreme temperature swings — Dr. Fixit Seal Tape 150MM is the construction chemical accessory that makes the difference between a waterproofing solution that performs completely and one that fails at its weakest point.
