Reliable and cost-effective solutions for joint waterproofing.


The ULTIMATE seal for formwork

The FormPlug is the simplest solution to seal the tie-bolt sleeve internally.

This revolutionary solution seals the void inside a formwork spacer.

The FormPlug comprises of a cap made from the same material as the HydroBar Evo over a solid plastic bung. The cap prevents water leaking out of the formwork spacer and the bung provides the mechanical anchor. In combination the cap and bung will stop water pressures up to 6 bar.

This water-activated, self-expanding sealing solution is simple. It ensures a perfect seal, stopping moisture / water infiltration with a single strike of a hammer. 100% watertight, quick and easy to install.

Works as a system in combination with Manorteq FormRing.

Size: 22 mm diameter to seal sleeves with an internal diameter of 22 mm.
