Macro-Industry Geotechnical Solutions

Three-dimensional confinement transforms cohesionless soils into load-bearing, erosion-resistant civil engineering assets.

Slope & Embankment Stabilization

Cellular confinement prevents sheet runoff erosion and deep-seated slip failures on steep cut-slopes up to 1:1. Perforated cell walls facilitate hydrostatic dissipation and root penetration for durable bio-engineering.

  • Revegetation Support
  • Riprap Replacement
  • Hydraulic Dissipation

Subgrade Load Distribution

By locking aggregate into an interconnected honeycombed mattress, geocells increase shear strength and stiffness (modulus improvement factor > 2.5), reducing base course thickness requirements by up to 50% over soft foundations.

Technical Inquiries

Frequently Asked Questions for Geotechnical Buyers

Engineering parameters, shipping capabilities, and customization options explained.

What parameters determine geocell cell depth and weld spacing?

The selection is governed by the structural load profile, slope angle, and aggregate characteristics. Typically, slope stabilization requires depths of 75 mm to 100 mm with weld spacing between 330 mm and 356 mm. Heavy vehicular load platforms and soft ground stabilization specify deeper sections (150 mm to 200 mm) with smaller cell diameters to optimize confinement stress.

How are geocells connected and anchored on steep embankments?

Adjoining modules are joined longitudinally and transversally using high-strength pneumatic plastic fasteners, corrosion-resistant steel staples, or polymeric keys. Anchorage requires engineered J-hook rebar stakes or polymeric anchors driven into stable subsoil at specified spacing, frequently paired with high-tenacity polyester tendons on impermeable membranes.

Why are textured and perforated strips preferred over smooth, non-perforated options?

Surface texturing (rhomboidal or dot embossment) increases the interfacial friction angle between the polymeric strip and infill aggregates. Perforations allow lateral drainage across adjacent cells to relieve pore water pressure, while enabling root interlock across sections for natural vegetated slope bio-protection.

Can Changhong customize roll and cell dimensions for specific project tenders?

Yes. We accommodate non-standard strip depths (50 mm up to 300 mm), varied weld distances (260 mm to 1000 mm), and custom expanded module lengths. Color formulations (black, green, yellow-sand) and custom UV antioxidant loading levels can be integrated to match client specifications.
