Product Overview

PeelSeal is a premium self-adhesive polymer modified bitumen membrane engineered for cold application without torches or adhesives. Simply peel and stick – the specially formulated SBS/APP modified bitumen layer bonds instantly to prepared surfaces, creating a permanent waterproof seal. Ideal for sites where open flames are prohibited (basements, tunnels, renovation) and for fast, clean installation [citation:2][citation:5].

Torch‑Free Safety

Perfect for gas stations, wooden structures, and confined spaces – no flame, no hot kettles, no fumes [citation:2].

Self‑Healing Technology

Micro cracks and minor punctures are automatically sealed by the flowable bitumen compound – extends service life [citation:1][citation:4].

High Bond Strength

PeelSeal achieves ≥1.5 N/mm adhesion to concrete and metal, preventing water migration and edge lifting [citation:1][citation:4].

Wide Temperature Range

Remains flexible down to -20°C and stable up to 70°C – suitable for all climate zones [citation:4][citation:5].

Key Applications

Below‑Grade / Foundations
Basement walls, slabs, and retaining structures – withstands hydrostatic pressure [citation:2][citation:3].
Cut‑and‑Cover Tunnels & Subways
Approved for underground rail and pedestrian passages where no flame is allowed [citation:2][citation:4].
Pools & Water Tanks
Potable water contact grades available – fish‑safe and non‑toxic after curing [citation:5].
Low‑Slope Roofing (Non‑Exposed)
Ideal under ballast, insulation, or green roof systems [citation:1].
No‑Flame Renovation
Schools, hospitals, and high‑rise buildings – retrofit without disrupting occupants.

Why Choose PeelSeal?

Fast Installation

Up to 40% faster than torch-applied – no cooling time, no waiting for adhesive to set.

Safe & Clean

Zero VOC, zero flame, zero hot asphalt fumes – environmentally friendly [citation:5].

Self‑Sealing Around Fasteners

When mechanically fastened, the bitumen flows around nails/screws – no extra sealants needed.

Frequently Asked Questions

What is the minimum application temperature?
PeelSeal can be applied down to +5°C. Below that, we recommend storing rolls at room temperature for 24h and using a warm‑air hand tool to activate the adhesive if needed [citation:3][citation:5].
Can it be used on vertical surfaces?
Yes, the high initial tack and bond strength allow vertical installation up to 3m without slipping. For higher walls, temporary mechanical fixing is advised until the adhesive cures.
How long does the adhesive last before installation?
When stored properly (cool, dry, <45°C), the self‑adhesive layer remains active for 12 months. Do not expose opened rolls to direct sunlight for more than a few hours.
Is a primer required?
For most concrete and masonry surfaces, a primer (water‑based or solvent‑based) is recommended to improve bond and block dust. Metal and wood may need specific primers [citation:3][citation:10].
