Deployed the Casagrande B125 XP to execute an 800 mm thick D-wall down to 28 meters in a constrained city zone with minimal downtime.
Access high-torque, precision slurry trench hydraulic cutters and D-wall rigs operated by certified field crews to execute watertight retaining walls across complex urban and marine geologies without capital expenditure.
Rent a D-Wall Rig / Request QuoteSlurry trench Diaphragm Walls (D-Walls) require heavy, high-precision hydraulic rigs capable of maintaining strict verticality while excavating deep, narrow trenches through tough soil profiles and rock strata under bentonite slurry support. Capital investment in specialized D-wall machinery can create significant financial friction for project-specific execution.
GRIMTECH’s specialized equipment rental division provides top-tier, high-capacity D-wall hydraulic rigs backed by complete mobilization support, certified field operators, and strict preventative maintenance protocols to minimise site downtime on critical infrastructure projects.
