TEGOLA Super Seal (P)-25
Premium roofing solution engineered for exceptional durability and performance.
Product Overview
TEGOLA APP MEMBRANE – TEGOLA Super Seal (P)-25
High-Performance APP Modified Torch-On Waterproofing Membrane
TEGOLA Super Seal (P)-25 is a premium APP (Atactic Polypropylene) modified torch-on bitumen waterproofing membrane engineered for long-lasting protection in demanding Indian climatic and structural conditions. Manufactured with a robust nonwoven polyester reinforcement and finished with a thermos-fusible polyethylene film on both sides, this membrane offers superior mechanical strength, flexibility, and dimensional stability.
The reinforced core enhances puncture resistance, tear resistance, and structural durability, ensuring reliable waterproofing for residential, commercial, and infrastructural applications. TEGOLA Super Seal (P)-25 can be installed as a base layer or a top layer (under protective screed), making it highly versatile for single-layer or multi-layer waterproofing systems.
TEGOLA Super Seal (P)-25 is suitable for:
• Underlay for pitched roofs with shingles
• Basement raft and unconfined retaining walls
• Sunken slabs and wet areas
• Concrete foundations and isolated footings
• Inverted roofs and exposed or covered terraces
• Podiums and parking decks
• Bridges, viaducts, and subways
• Metro tunnels and underground transit structures
• External waterproofing of water-retaining structures
Application Method:
- Prepared surfaces shall be primed using TEGOLA Primer (S)-25 @ 0.2-0.3 Ltr/sqm, depending on substrate.
- Allow the applied primer to dry. After the bituminous primer has dried, membrane rolls are spread over the entire area for alignment with the recommended overlaps. Allow the membrane to remain for 15-20 minutes to relieve stress. Reroll the membrane sheet from both sides towards the center without disturbing the alignment.
- Maintain side overlaps of 100 mm. Maintain end overlaps of 150 mm. The membrane shall be installed from the lowest point of the slope and progress to the highest point. Maintaining the membrane's previous alignment, start unrolling the membrane and simultaneously torch the primed substrate and the underside of the membrane.
- When the underside heating of the membrane exposes a shiny bitumen surface, roll forward the membrane and press firmly from above against the substrate to obtain superior bonding.
- Maintaining the side and end overlaps, a thin bead of bitumen produced during torching at the seams should be smoothed out with a round tip hot trowel, ensuring a tight and impermeable seal.
- Once torching of the membrane is commenced, care should be taken to avoid shifting / lifting of the membrane, and take care to prevent damage to the membrane.
- On a vertical surface, the end edge of the membrane should be suitably terminated by tucking it into the groove made on the vertical surface, and the groove filled with cement sand mortar (or) by fixing mechanically with metal flashing, the edges of the metal flashing flush finished with caulk sealant.
- As TEGOLA Super Seal (P)-25 is not resistant to UV rays nor resistant to puncture damage due to regular foot traffic, the installed membrane should not be left exposed to the Sun nor subjected to direct foot traffic.

SHELF LIFE
The membrane has a shelf life of 5 years when stored as above. Failure to comply with recommended storage conditions may result in premature deterioration of the product.
Storage:
- TEGOLA Super Seal (P)-25 membrane rolls must be stored between 5°C to 40°C in a dry place under a covered shed and protected from extremes of temperature, rain, heat, and sun and UV rays.
- Rolls must be stored in an upright vertical position on a flat, even surface.
- Avoid stacking of rolls horizontally on their sides or in a double-stack position.
- Protect the rolls if stored outdoors with opaque protective covers to minimize sunlight and UV exposure.
Safety:
As with all bitumen products, caution should always be exercised. Protective clothing, such as gloves and goggles, should be worn. Treat any splashes on the skin or eyes with fresh water immediately. Should any of the products be accidentally swallowed, do not induce vomiting, but call for medical assistance immediately.
