TPE Expansion Joints – Tapes & Profiles

GreenShield™ Expansion Joint Tapes and Profiles are based on thermoplastic elastomer chemistry, designed for primary seal of high movement expansion gaps, suitable across various surfaces/substrates, providing water tightness, continuity of seal throughout changes in plane and direction including curves and corners, high degree of puncture resistance and elongation compared to traditional membrane based joints. Redundant adhering system provides double protection from water leakages. We manufacture a wide range of tapes and profiles, suited for applications worldwide. GS 2K adhesives are designed for applying expansion joints.

GS TPE EJ Tapes

GS EJ Tapes are flexible waterproofing tapes with advanced adhesion properties. The tapes have very high crack resistance and joint bridging capabilities, excellent resistance to chemical, UV and weathering, root penetration. It performs in a wide temperature range from -50°C to +95°C and is heat weldable. These flat tapes are manufactured and supplied in standard widths of 100 mm, 200 mm and 500 mm. Custom sizes can be manufactured. The tapes are pre-holed for anchoring adhesives above and below the joint flaps to the substrate.

GS TPE EJ 75 Eagle

This preformed profile is designed for covering gaps of 75 mm, with specific redundant flaps for heat welding to TPO membrane as well as anchoring to mother slabs. Best suited for podium and roof application. Designed using flexible elastomer material, the preformed profile has excellent resistance to chemicals, acids, bases, corrosion, UV, weathering, and root penetration. Besides this, it works well in a wide temperature range from -60°C to +125°C.

GS TPE EJ 250 Ohm

The preformed profile is designed for covering gaps of 250 mm. Manufactured using flexible elastomer material, the preformed profile has excellent resistance to chemicals, acids, bases, corrosion, UV, weathering, and root penetration. Besides this, it works well in a wide temperature range from -60°C to +125°C.

Application Areas

Depending on the size of the building or project; architects and builders provide expansion joints across areas like split slabs, roofs, exterior walls, below grade / basements, podiums, interiors and so on. These joints are required to safely absorb temperature induced expansion and contraction or construction materials, absorb vibration and hold parts together or to allow movement in case of ground movement. However, it is important to seal these gaps from moisture, heat and environmental forces, without affecting the purpose of the gap. GS EJ is suitable in waterproofing expansion joints across flat roofs, exterior walls, split slab decks, podiums, parking areas, basements; applied as exposed or covered below PCC.
