Underground Construction & Foundation HDPE Geomembrane: Effective Waterproofing for Tunnels, Basements, and Sub-Grade Stabilization

Product Description:
Protect critical infrastructure from moisture ingress and soil-related instability with our HDPE Smooth Geomembrane. In underground construction, it acts as a highly effective waterproofing and vapor barrier membrane for subway systems, tunnels, and deep basements, preventing water infiltration that can lead to structural damage, corrosion, and interior mold growth. In transportation and building projects, it serves as a crucial capillary break layer beneath foundations and within road or railway sub-grades. This application effectively controls moisture movement from expansive soils and collapsible loess, significantly enhancing soil stability, reducing differential settlement, and extending the service life of the entire structure. It is a cost-effective engineering solution for ensuring long-term durability and reducing maintenance costs.

Ideal Applications:

• Primary Waterproofing Membranes for Tunnels, Subways, and Cut-and-Cover Structures

• Vapor Barriers in Below-Grade Parking Garages and Building Foundations

• Separation and Stabilization Layer in Highway and Railway Embankments

• Moisture Control Layer in Expansive Clay and Collapsible Loess Soils

Technical Specifications:

• Thickness: 0.3mm - 3.0mm

• Width: 1m - 9m

• Roll Length: 30m - 100m (Custom lengths available)
