Excavation depth and groundwater elevation should be confirmed by your geotechnical report, so please share that data so we can help confirm an appropriate panel length.
Application
This wall is used wherever keeping groundwater out of an excavation or below-grade structure is the main construction concern, whether the wall is temporary or intended to remain in place.
- Basement and foundation excavation support: keeps groundwater out of the working area during construction.
- Underground utility vault walls: forms a sealed enclosure around vaults and below-grade chambers.
- Temporary construction dewatering: lowers groundwater interference within an excavation footprint.
- Permanent below-grade cut-off walls: stays in place as a long-term groundwater barrier once construction is complete.
Because excavation support design is safety-critical, we recommend having your geotechnical engineer confirm wall depth and bracing requirements before ordering.
Advantages
- Effective groundwater exclusion: sealed joints limit water infiltration into the excavation.
- Usable temporary or permanent: can be extracted after construction or left in place as a lasting barrier.
- No corrosion during extended use: holds up through longer construction schedules without section loss.
- Lighter than comparable steel sections: can simplify handling and installation logistics on constrained urban sites.
- Consistent seal quality: tightly controlled joint dimensions support reliable water exclusion across the full wall run.
For deep excavations requiring significant lateral bracing, this product is typically used together with an engineered shoring or bracing system rather than as a stand-alone structural wall.
