A tie-bolt sealing system, both around and inside the sleeves.
FormRing
The ULTIMATE seal for formwork
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.
Installation of FormRing
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.

FAQ’s
Dip in clean water momentarily, this will allow the rubber to slide on to the sleeve as though it has been lubricated.
As standard, it will fit an external diameter of 24 mm to 30 mm. The ring stretches.
No. All Manorteq ancillary products are developed and selected to integrate seamlessly with the Xypex waterproofing system, as well as others.
No. This product can be used without removing the sleeve.
FormRing is an external watertight sealing ring used to prevent water ingress along the outside of formwork spacers or tie bolt sleeves in concrete structures.
Manorteq FormRing seals water on the outside of the spacer or sleeve, while FormPlug seals the inside of hollow spacers. For full protection, FormRing and FormPlug are recommended together as a complete waterproofing solution.
Our FormRing is manufactured from hydrophilic, water-swellable synthetic rubber, the same material as the Manorteq HydroBar Evo, which expands when in contact with water to create a permanent seal.
When water comes into contact with the FormRing, the synthetic rubber swells and closes any gaps around the spacer or sleeve created be concrete shrinkage, preventing water from passing through the concrete.
FormRing should be installed:
- In the middle and over the outside of the formwork spacer, and
- With a minimum concrete cover of 100 mm.
Correct positioning is essential for effective waterproofing.
Manorteq FormRing is compatible with spacers with an external diameter of 24–30 mm.
Due to its soft and elastic composition, one FormRing size can accommodate multiple spacer diameters.
- Slide the FormRing onto the spacer/sleeve before concreting
- Position it centrally on the outside of the spacer (wetting the spacer can make installation easier)
- No special tools are required.
Swelling capacity depends on the type of water:
- Rainwater: up to 500%
- Concrete water: up to 400%
- Salt water: up to 200%
FormRing has a service temperature range of –50 °C to +70 °C, making it suitable for a wide range of climatic conditions.
