High performance sealing tape for cracks, expansion and construction joints  weather-resistant and permanent flexible  high movement capacity  thermal welding ensures secure, watertight joints  excellent adhesion to the support PRODUCT DESCRIPTION VANDEX FLEXTAPE E is a sealing tape made of FPO (flexible polyolefine). Extremely durable, it has excel­ lent resistance to weathering and is UV stable. The bond to the substrate is achieved using a suitable adhesive.

AREAS OF APPLICATION The VANDEX FLEXTAPE E system bridges and seals expansion and construction joints as well as cracks in concrete constructions. The maximum permissible expansion under continuous load depends on the thickness of the tape and the width of the unbonded flex zone. The VANDEX FLEXTAPE E system is resistant to hydrostatic pressure on the active side. On the passive side, only in combination with a counterpressure structure. In presence of a negative water pressure up to 0.3 bar, there is no need for a counterpressure structure. Expansion joints LAP JOINT WELDING Hot air...

FLEXTAPE E APPLICATION 1. The concrete surface to be covered must be sound, normal movement is anticipated, it is advisable to leave clean and free of dust, oil and grease. The laitance has some slack in the tape in the flex zone. 4. Float the final coating by trowel. In case of movement 2. Apply the adhesive as an initial coating to both sides joints, a flex zone must be kept free of adhesive. In case of the joint or crack with a trowel or toothed comb. With of any necessary overcoating, the adhesive must be sprin­ expansion joints, an expansion zone of sufficient width is kled immediately...
