How to Use HDPE Geocell ?

Are you looking for the geosynthetics for slope or road?Geocell Driveway lane stabilization system has significant advantages, including enhancing foundation bearing capacity, preventing soil erosion, improving road stability, convenient construction, and environmental protection and energy saving effects. This versatile geosynthetics can not only effectively improve project quality, but also significantly reduce costs. It is an indispensable solution in modern road construction and maintenance.

But,there are lots of people do not know how to use HDPE geocell.

Usually,HDPE geocell should be layed under nonwoven geotextile and then use geocell caps and trials to connect with each panels and make them stable.

The details about using geocell is as below：

1. Prepare the Site

Clear the area: Remove all debris, vegetative cover, and unnecessary soil from the area where the geocell will be placed.
Create a suitable base: If needed, replace the removed soil with materials that meet project requirements and complete any necessary earthwork.

2. Deploy and Anchor the Geocell

Unfold and orient: Unfold the collapsed geocell panels and lay them on the prepared surface, aligning them in the direction of the slope or load.
Secure the top edge: Anchor the top edge of the geocell to the crest of the slope using methods like stakes, pins, or anchor trenches.
Stretch and align: Stretch the geocell panels down the slope to achieve the desired shape and size, ensuring they are aligned and form a continuous surface.
Connect panels (if necessary): If multiple panels are needed, join them together by stapling or using other fastening methods.
Install anchors (for slopes): For slope protection, install tendons or other anchoring systems at the toe of the slope, attaching them to the geocell every few cells.

3. Infill the Cells

Choose the right material: Select infill material based on the project’s soil properties and needs.
Fill carefully: Using a dump truck or front-end loader, carefully fill the cells to avoid damaging them with a high drop height.
Overfill slightly: Fill the cells a little higher than the geocell walls to allow for settling and compaction.

4. Compact and Finish

Compact the fill: Use an appropriate method to compact the infill material within the cells, ensuring it is done without damaging the geocell.
Cover the geocell: Make sure the geocell is completely covered after infilling to protect it from prolonged exposure to sunlight and the elements.

How Does Geocell Work？

Geocells are three-dimensional, honeycomb-like structures typically made from high-density polyethylene (HDPE).

By confining and reinforcing infill materials like soil/vegetation, sand, gravel or concrete, geocells create a stable, load-bearing surface

What is the Best Method for Attaching Geocell to a Slope?

Prepare precut or pre-connect panels at the top of the slope. Anchor the upper edge of the Geocell to the top of the slope. Stretch the panels down the slope and stake every other cell at the bottom. Sometimes, the project may need an anchor trench, which shall be excavated according to the project designs.

How Long Does Geocell Last?

The polymer used in geocells is the primary determinant of durability: HDPE: Highly resistant to chemical degradation and oxidation, HDPE geocells last 50–100 years in buried applications and 20–40 years when exposed to UV radiation without stabilizers
