HDPE honeycomb geocell

HDPE Honeycomb Geocell Full Product Introduction

1. Basic Definition & Aliases

Official Name

HDPE honeycomb geocell, also called Cellular Confinement System (CCS) — a 3D honeycomb geosynthetic material made of modified high-density polyethylene sheets.

Common Trade Names

HDPE geocell, honeycomb soil stabilization grid, gravel stabilizer cell, 3D HDPE cellular mat, slope protection honeycomb cell

2. Manufacturing Process

· Raw material: Virgin HDPE mixed with anti-UV, anti-oxidant additives for long outdoor service life.

· Extrude into HDPE sheets, available in smooth or textured surface; optional perforated holes for drainage & plant root growth.

· Connect sheets by high-precision ultrasonic hot welding to form interlocked honeycomb cells.

· Finished panels are fully foldable for compact transportation; expand on-site to form a continuous rigid honeycomb network.

3. Core Standard Specifications

Dimension Parameters

· Cell depth (height): 50 / 100 / 150 / 200 / 250 / 300 / 400 mm

· Welding pitch (cell span): 330 / 400 / 500 / 660 / 800 / 1000 mm

· Sheet thickness: 1.0–2.0 mm (1.5–1.8 mm for heavy-load projects)

· Colors: Black (main anti-UV grade), green, tan, customized colors

· Surface types: Smooth, textured (increase friction), perforated (water permeable)

Key Mechanical Performance

· Sheet tensile strength ≥ 20 kN/m

· Weld node peel strength ≥ 8 kN/m (core safety index)

· Working temperature range: -45℃ ~ +70℃

· Resist acid, alkali, salt, sewage corrosion; anti-freeze-thaw cycling

· Design service life: 50–75 years under outdoor exposure

4. Working Principle — Lateral Confinement Mechanism

Loose sand, gravel and soft soil easily slide, deform and sink under vertical loads.

After unfolding and filling HDPE honeycomb geocell:

· Each independent honeycomb cell locks infill tightly, restricts lateral displacement and expansion of soil/gravel;

· Scattered vertical pressure is evenly distributed across the subgrade, lifting ground bearing capacity by 2–3 times;

· Forms an integrated lightweight rigid mattress, cutting foundation settlement by 40%–65% compared with unreinforced soil.

5. Main Advantages

① Low Logistics & Fast Construction

· Foldable compression reduces transport volume by over 80%, greatly cut freight cost;

· Lightweight, unfold manually without large heavy machinery; construction period shortened by 30%+.

② Outstanding Geotechnical Performance

· Perfect for soft soil, muddy ground, collapsible loess and desert sand stabilization;

· Perforated version achieves natural infiltration, matching sponge city and ecological greening demands;

· Anti-rutting for heavy-duty roads, anti-scour & anti-landslide for steep slopes, river embankments.

③ Cost & Eco-Friendly

· Reduce gravel base thickness by 50%–80%, save quarry aggregate consumption;

· Allow local on-site soil/sand as filling material, lower excavation and aggregate transportation cost;

· Vegetation can grow inside cells for ecological restoration; HDPE raw material is recyclable.

④ Extreme Durability

· Anti-UV aging, resistant to seawater, industrial chemical wastewater, no cracking or embrittlement after long-term exposure.

6. Full Application Scenarios

1) Road & Traffic Engineering

· Highway, railway soft subgrade reinforcement, road widening reconstruction;

· Mine haul roads, temporary construction roads, parking lots, logistics yards, airport storage areas;

· Driveway gravel stabilization for residential and commercial zones.

2) Slope & Water Conservancy Erosion Control

· Highway/railway cut/fill slope greening;

· Riverbank, reservoir, channel anti-wash protection;

· Mine wasteland restoration, desert sand fixation, mountain slope landslide prevention.

3) Retaining Wall & Landscape Projects

· Lightweight geocell soil retaining walls (eco-friendly, no concrete gravity wall);

· Park trails, golf courses, rain gardens, permeable pavement for sponge city.

4) Municipal & Landfill Works

· Underground drainage layer; landfill covering anti-slip layer; tree root protection grids.
