Case Study Brief

The residential project required gravel surfaces that were comfortable to use and consistent with the landscape setting. Geosynthetics Africa supplied and installed BERA Gravel Fix® Pro for the driveway and garden paths. The cellular panels confine gravel and reduce its movement during use. The integrated geotextile separates the infill from the layer below, while edging defines and retains the finished surface. The work covered base preparation, panel placement and trimming, gravel filling and compaction across approximately 800 m². Detailing at boundaries and changes in direction helped achieve a consistent finish. Drainage and load capacity depend on the supporting pavement design and ground conditions. The system reduces gravel displacement but still requires inspection, weed management and occasional replenishment of infill.

The Installation Challenge

The residential driveway and garden paths needed a stable gravel finish through changes in alignment and at landscape boundaries. Base levels, edge restraint and infill distribution needed to work together over the approximately 800 m² area.

BERA Gravel Fix® Pro was placed on the prepared base, trimmed to the surface geometry and filled with the specified gravel. Perimeter edging defined the installation and helped retain the infill.

Installation Sequence

1

Prepare the supporting base

Establish the required formation, compacted base and finished levels for the expected traffic and site drainage conditions.

2

Place and trim cellular panels

Lay BERA Gravel Fix® Pro panels on the prepared surface, maintain the integrated geotextile continuity and trim around boundaries and interfaces.

3

Install edging and gravel infill

Secure the perimeter edging and fill the cells with the specified gravel, distributing the infill evenly across the panels.

4

Compact, finish and inspect

Complete compaction and surface finishing; review edge restraint, gravel cover, levels and the drainage arrangement before handover.

Field Quality Assurance (QA/QC) Checklist

Quality checks recorded on this installation.

Subgrade clearance and compaction verified before panel lay
MOT sub-base depth and compaction checked against 15–25 cm spec
Sharp sand levelling layer checked for surface flatness
Panel overlap and geotextile lip continuity confirmed at every joint
Gravel infill depth checked (15–20 mm above cell wall, full coverage)
Edge restraint alignment and fixing checked along all boundaries
Final surface level and drainage fall checked against surrounding paving

“I can finally park the bike without it sinking into loose stone, and it stays upright on the side-stand without digging in. The whole driveway drains within minutes after rain, and I haven't had to touch the gravel since it was laid.
