Geopolymer Spray Rehabilitation with GEOKRETE

Giving underground infrastructure a second life of more than 50 years

Obsolete infrastructure: rehabilitate or replace

Aging infrastructure such as culverts, catch basins, manholes and pipes bring serious problems of parasitic water infiltration, structural loss, corrosion, abrasion and much more.

Contrary to what one might think, the solution is not always to come and replace the product. In fact, for several reasons, it may be advantageous to rehabilitate the existing infrastructure.

Rehabilitation makes it possible to restore the structural capacity of infrastructures at a fraction of the replacement cost, while reducing traffic management. Rehabilitation extends the useful life of these infrastructures by 75 years and does not usually require excavation.

Geopolymer Spray Rehabilitation with GEOKRETE

A proven solution for pipes, culverts, and large diameters.

The engineered designs allow the system to withstand all live, dead, and hydrostatic loads, enabling the pipe to fully regain its structural integrity.

GEOKRETE is specifically designed for large-diameter rehabilitation. It combines the advantages of cementitious materials and polymer-based products—offering the appearance, texture, and application properties of a cementitious mortar, while providing corrosion resistance comparable to a polymer. Unlike polymers, GEOKRETE can be applied in a single layer up to 5 cm thick, creating a complete structural lining inside pipes, manholes, and other underground infrastructure. Over the long term, its specialized additives minimize degradation and extend the service life of the rehabilitated structure for up to 75 years.

When required—particularly when the pipe invert is severely deteriorated—an additional step can be included to rehabilitate the invert using a restoration mortar specifically designed for this purpose.

Marked advantages over conventional solutions

Rehabilitating large-diameter pipes with GEOKRETE spray-applied geopolymer provides many benefits over conventional replacement:

Ideal for large diameter pipes (900 mm and more)
Available at a fraction of the replacement cost
Restore the structural capacity of the infrastructure
Fast execution, no excavation required;
Reduces the impact on citizens and related to traffic management
Eliminates the negative impact of differential soil settlement following excavation
Reduce repairs following work
