Effective Grout Curtain Barriers for Water Control
Groundworks delivers grout curtain barriers using polyurethane injection, creating robust water control and soil stabilization solutions. Ideal for commercial, industrial, and government projects, our barriers protect against water intrusion and soil movement.
Reliable Barriers for Water Control and Stability
Groundworks’ grout curtain barrier solution uses advanced polyurethane injection to form effective water control barriers. Designed for diverse infrastructure needs, our grout curtains stabilize soils and protect structures against water intrusion in commercial, industrial, and government projects.
Creating Grout Curtain Barriers with Polyurethane Injection

Groundworks installs grout curtain barriers by injecting polyurethane into the soil, using proprietary injection techniques, where it expands to form a continuous underground barrier. This method effectively blocks water flow, stabilizes surrounding soils, and enhances the integrity of infrastructure projects. Ideal for protecting subgrade infrastructure, tunnels, and retaining structures, our grout curtains provide essential support for projects facing water management challenges.
When to Consider Grout Curtain Barriers
Grout curtain barriers are essential for projects facing water infiltration risks, soil movement, or stability concerns in water-prone areas.

- Water Seepage in subgrade structures: Persistent water near structures may indicate a need for a grout curtain.
- Shifting Soil Conditions: Projects with soil erosion or instability benefit from the added support of a barrier.
- High Water Table Levels: Elevated groundwater can destabilize infrastructure without water control measures.
- Protecting Critical Infrastructure: Structures near water sources or flood-prone areas require water barriers.
- Soil Washout Concerns: Soil loss due to water flow can be managed with a grout curtain barrier.
Benefits to Grout Curtain Barriers
Groundworks’ grout curtain barriers provide an efficient, non-invasive solution for controlling water and stabilizing soil across diverse applications.

- Water Flow Control: Polyurethane barriers block unwanted water infiltration.
- Stabilized Soil Conditions: Reduces soil movement and erosion around structures.
- Non-Invasive Installation: No excavation needed, minimizing disruption.
- Long-Lasting Protection: Durable barriers for critical infrastructure projects.
- Tailored for Site Needs: Customized solutions to match each project’s water and soil requirements.

Products We Use
Polyurethane Grout Curtain

What We Do
Polyurethane is injected into the ground to form a continuous, impermeable barrier, blocking water flow and stabilizing soil around critical structures. This process ensures robust water control without the need for excavation.
How It Works
Polyurethane is injected at targeted depths to create a solid underground barrier that prevents water infiltration and stabilizes the surrounding soil.

FAQs
A grout curtain barrier is an underground barrier created by a unique polyurethane injection approach to create a highly dense matrix of soil and polyurethane. This matrix restricts groundwater migration and intrusion.
Polyurethane is injected into the soil to form a continuous barrier that blocks water and reinforces ground stability.
Grout curtains are ideal for projects near water sources, tunnels, and any subgrade infrastructure needing water control and soil support.
No, polyurethane injection is a non-invasive technique that achieves barrier creation without surface disruption.
With decades of experience, Groundworks designs tailored grout curtain solutions to meet the unique demands of each project.
