Grouts and resins we make, and apply

Injection grouts, resins, gels, microfine cement, sealants and coatings for ground, tunnel and water-control work, formulated by our research and development team and made at our plant in Alwar. We apply them with our own crews, adjusted to the ground and the water on each site.

The full product range, with grades, is on our product website, aqueonglobal.com. Each product below links to it, in a new tab.

Choosing a grout

The ground and the water decide

No single resin suits every condition, and the wrong choice is the commonest reason a grouting campaign under-performs. This is how we match them.

Which grout can enter which groundIndicative chart. Acrylate gels reach the finest soils, from silty sands; PU resins and microfine cement work in sands, gravels and fissured rock; cement grout needs coarse ground or open fissures; polyurea silicate is used to consolidate fissured rock. ClaySiltSilty sandSandGravelFissured rockCement groutMicrofine cement · GeoFinePolyurethane · PuTeRA, DrucHydSilicate resin · DrucPietraAcrylate gel · TeracrylFINER · COARSER
Indicative only. We choose the grout after testing the ground and the water, and confirm it with a site trial.

Contractor first

Need it applied, or need the material?

Need it applied? We are a ground engineering contractor first. We design the treatment, make the grout for your ground and inject it with our own crews and plant. Request a site inspection →

Buying material for your own crews? Raw materials, white labelling and contract manufacturing are handled by Aqueon Global.
