DISPLACEMENT

Manufactured from tough, virgin P.V.C. for maximum strength and durability, Eyeleted Hydrofoil Waterstop is anchored firmly in its correct position throughout the pouring process. The unique outer flanges with metal eyelets at regular intervals, wired to surrounding reinforcement or other convenient fixing points, maintain absolute rigidity. As the concrete contracts on curing, the waterstop is held in slight tension and the inner faces of the specially shaped edge bulbs are held firmly against the concrete, providing a reliable seal. Subsequent expansion, contraction and differential movement is safely accommodated by the centre bulb and webs of the waterstop.

The wealth of knowledge gained by us through technical develop- ments and practical experience over many years is available to you through the Expandite Waterstop Service. This covers every aspect of design, fabrication and installation of both P.V.C. and rubber waterstop networks. Where required, complicated networks can be prefabricated free of charge and special tools and equipment are provided for all on-site jointing. Write for the comprehensive technical literature which fully describes all Expandite Waterstops and consult us in the earliest design stages of any project to derive maximum benefit from our Waterstop Service.
