Performance

hDR WATERSTOP is suitable for use in potable water situations. hDR WATERSTOP provides superior expansion (300% unrestrained) to seal and fill voids and cracks in the concrete. The performance of hDR WATERSTOP is not effected by continuous wet dry cycles and easily out performs blended hydrophilic materials. (see fig.1)

Features

hDR WATERSTOP is designed to replace passive PVC/Rubber waterbars, thereby eliminating the requirement of special pieces, split forming and seam welding. Independent testing has confirmed that hDR WATERSTOP will perform successfully at over 50m of hydrostatic water pressure, under both continuous immersion and wet/dry cycling.

hDR WATERSTOP is manufactured in lightweight, flexible coils that are easily installed by a single worker. The product is applied to concrete, steel and PVC (Pipes) using INSTAFLEX Waterproof Mastic. INSTAFLEX can be used to stick the waterstop to damp (not wet) concrete. Coil ends are overlapped 100mm to form a continuous waterstop.

Benefits

• Independent testing has confirmed that hDR WATERSTOP will perform successfully at over 50m of hydrostatic water pressure, under both continuous immersion and wet/dry cycling.
• suitable for use in potable water situations
• Easily Applied

Summary

hDR WATERSTOP is manufactured in lightweight, flexible coils that is easily installed. It provides superior expansion and is not affected by wet.dry cycles ensuring that the hDR waterstop provides a positive seal every time.
