A structural wall solution for deep excavation and containment

Slurry and diaphragm walls are constructed under slurry support to form reinforced concrete walls. This technique provides both structural support and groundwater cutoff, making it suitable for deep excavations and complex underground works.

Key advantages of Slurry and Diaphragm Walls

Structural Capacity & Stiffness

Slurry and diaphragm walls provide high structural strength and rigidity, making them suitable for deep excavations and projects with significant lateral loads or adjacent sensitive structures.

Effective Groundwater Control

The continuous concrete wall acts as a low-permeability barrier, limiting groundwater inflows and supporting excavation stability in high water table conditions.

Precision in Complex Environments

Constructed under slurry support, diaphragm walls allow for accurate wall alignment and depth control, even in dense urban settings or variable ground conditions.

Applications

Slurry and diaphragm walls are used across infrastructure, commercial, and institutional projects where deep excavation support and groundwater management are critical.

Deep Excavations & Basements

Used to support deep excavations for basements, underground structures, and cut-and-cover works, while controlling ground movements and water ingress.

Urban & Sensitive Sites

Well suited to dense urban environments or sites adjacent to existing buildings and infrastructure, where wall stiffness and controlled construction are essential.

Infrastructure & Containment Works

Applied to infrastructure projects such as stations, shafts, and underground facilities, as well as containment structures requiring long-term groundwater control.

Quality Assurance and Execution

Soletanche Bachy Canada delivers slurry and diaphragm wall solutions using specialized excavation equipment, slurry management systems, and experienced construction teams. Construction methods are selected based on ground conditions, excavation depth, and project constraints to ensure safe and compliant execution.

Quality assurance measures include monitoring slurry properties, trench geometry, reinforcement placement, and concrete quality to ensure the wall meets structural and hydraulic performance requirements.
