Permeable Paving & Surface Stabilisation Systems for Africa
BERA® Gravel Fix – Gravel Stabilisation Systems in Africa
Engineered Permeable Gravel Stabilisation Systems for Roads, Parking & Infrastructure
Geosynthetics Africa is the leading supplier of BERA® Gravel Fix systems across Africa, delivering engineered permeable paving solutions for gravel stabilisation, load distribution, and long-term surface performance.
BERA® Gravel Fix is a high-performance cellular stabilisation system designed to create stable, trafficable, and fully permeable gravel surfaces for infrastructure, commercial, and environmental applications. With integrated geotextile backing and engineered honeycomb cell structure, it delivers superior load transfer, erosion control, and drainage performance in demanding operating conditions.
Why BERA® Gravel Fix
- Stable and trafficable gravel surfaces for vehicles and pedestrians
- High permeability – rapid stormwater infiltration up to ~180 L/m²/s
- Prevents rutting, displacement, and gravel migration
- Integrated geotextile layer (Typar®) for filtration, separation, and weed control
- Suitable for cars, service vehicles, and trucks
- UV stabilised, frost resistant, and long-life design (>100 years)
- Fully recyclable and Cradle-to-Cradle Certified™ Silver
What is BERA® Gravel Fix?
BERA® Gravel Fix is a polypropylene cellular confinement system with a hexagonal honeycomb structure designed to stabilise granular materials while maintaining full permeability.
The system combines:
- Structural confinement (cellular grid)
- Integrated geotextile filtration layer
- Optimised cell geometry for load distribution
This creates a stable, porous, and load-bearing surface suitable for a wide range of applications – from residential driveways to heavy-duty infrastructure.
The engineered trapezoidal wall structure (approx. 32 mm depth) maximises strength while minimising material use, delivering high performance with efficient design.
Applications Across Africa
BERA® Gravel Fix is specified across multiple sectors:
Infrastructure & Civil
- Access roads
- Service roads
- Road shoulders
- Temporary and permanent haul routes
Commercial & Industrial
- Parking areas (light to heavy traffic)
- Industrial yards
- Logistics and storage areas
Urban & Environmental
- Pathways and walkways
- Parks and public spaces
- Landscaping and architectural projects
Specialist Applications
- Sloped access routes
- Golf courses and estates
- Roof terraces and green roofs
System Performance
Load Distribution
Cellular confinement distributes loads laterally, reducing stress on the subgrade and preventing deformation.
Surface Stability
Prevents rutting, wheel tracking, and material displacement even under repeated traffic loading.
Permeability
Allows full infiltration of rainwater directly into the subgrade, supporting sustainable drainage systems (SUDS).
Erosion Control
Locks aggregate in place, preventing washout and surface degradation.
