Retaining walls
Sheet pile wall in Quebec, New Brunswick, the N.W.T. and Nunavut
JPC Consultants inc. designs sheet pile walls in Quebec City and across Quebec, to support an excavation in loose soils, in an urban area or near a body of water.
Our approach
A steel screen for safe excavation
A sheet pile wall is made of steel sections driven into the ground and interlocked with one another. They form a continuous screen that holds back soil and, often, water.
We design temporary and permanent sheet pile walls. They are used for excavations in loose soils, in urban areas or near bodies of water.
We carry out the calculations to current standards. We take into account the soils, water levels, surcharges and nearby structures.
Before the design, we compare sheet piles with other possible systems, such as the soldier pile and lagging wall (Berlin wall). You can then choose knowing how each option affects cost and construction.
- Temporary or permanent
- Loose soils and water
- Urban job sites
- Calculations to current standards
Choosing well
When should you use a sheet pile wall?
Sheet piles are suited to excavations in loose soils, especially where water is present. Their continuous screen limits water inflow into the excavation.
They are also used to build a cofferdam. The sheet pile enclosure then allows work in the dry in a waterway or body of water.
Depending on the height to retain, the wall can be cantilevered or supported by anchors or struts. The choice comes from the calculations and the space available around the excavation.
Installing sheet piles requires access for machinery. From the design stage, we take into account this access, nearby structures and the construction sequence.
