Diaphragm walls — installation and ground treatment overview

HOW IT WORKS

Installation sequence

01

Guide & excavate

Construct guides and excavate panels under specified support fluid.

02

Reinforce & concrete

Clean the base, lower reinforcement and place concrete by the approved method.

03

Stage & monitor

Coordinate panel joints, staged supports, excavation and monitoring.

APPLICATION & ENGINEERING

Deep excavation retention with reinforced concrete panels

Panels are constructed in slurry-supported trenches. Panel joints, verticality and controlled concrete placement govern wall continuity and performance.

When to choose this method

Diaphragm walls use reinforced concrete panels constructed in supported trenches. They can suit deep excavations where wall stiffness and groundwater control are important, subject to the ground profile, panel layout and joint design.

Planning the installation

The ground investigation, groundwater conditions and structural requirements inform method selection. Working access, installation sequence and effects on neighbouring structures are reviewed before execution.

Construction control points

  • Construct guides and excavate panels under specified support fluid.
  • Clean the base, lower reinforcement and place concrete by the approved method.
  • Coordinate panel joints, staged supports, excavation and monitoring.

Check slurry properties, trench stability, verticality, reinforcement and tremie concreting records. Inspect panel joints and monitor wall response during staged excavation.

FROM SITE DATA TO A TECHNICAL PROPOSAL

Define the ground. Plan the solution.

Share the site location, geotechnical report, structural loads or excavation requirements, drawings and target programme. These inputs allow the engineering team to assess method suitability, equipment access, installation sequence and the required verification plan.
