A tie-bolt sealing system, both around and inside the sleeves.


The ULTIMATE seal for formwork

The Manorteq FormRing is the simplest solution to seal externally around a sleeve of a tie-bolt.

This revolutionary solution seals the external surface of a formwork spacer / sleeve.

The FormRing prevents water leaking around the formwork spacer / sleeves which occurs as a result of the shrinkage of concrete. It will stop water pressure up to 6 bar.

The FormRing is made from the same material as the HydroBar Evo.

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

Works as a system in combination with Manorteq FormPlug.

Size: 24 mm internal diameter to seal sleeves with an external diameter of 24 mm – 30 mm.

The FormRing should be installed over the outside of the formwork spacer, centred in the middle. There should be a minimum of 100 mm from any exposed surface of the concrete.

Due to its soft and elastic composition, each FormRing can be easily installed on spacers.

Dipping the spacer in clean water will make the installation easier.

Installation of the product under continuous rain should be avoided as premature swelling might occur.

If premature swelling occurs, the product will return to its original dimensions after drying.
