A world expert in construction chemistry & challenging jobsites

CHRYSO^®TBM - Type A+B backfill grout

The combined use of CHRYSO^®TBM SGS 150 retarder and CHRYSO^®TBM SGS 400 stabilizer ensure exceptional grout stability over several days.
The grout stability and low viscosity allow for pumping over long distance and reduce the need for pipes flushing during machine stoppages, delivering unparalleled performance to meet the most demanding jobsites.

Sustainability

New CHRYSO®TBM SGS solution provides high-performing environmentally-friendly backfill grout for tunnels and underground city projects, that significantly reduce tunneling construction site’s environmental footprint, thanks to bentonite substitution.

CHRYSO is focusing on providing sustainable solutions to our customers and lowering CO₂ emissions

The stabilizer’s unique formulation allows to completely substitute bentonite: no more bentonite storing neither transport will contribute to a better environmental management of the site.
CHRYSO offers a sustainable supply with our CHRYSO^®TBM SGS 400 stabilizer which is based on renewable raw materials (bio-sourcing) and the possibility to use alternate cementitious materials

We are bringing a high-performing environmentally-friendly backfill grout for tunnels and underground city projects.
