Geofabrics offers a range of engineered slope, embankment and retaining wall solutions of use in transport infrastructure projects.
To respond to the different problems associated with instability of rock faces, Geofabrics also has a broad range of independently verified rockfall mitigation systems.
For slopes over 70°, Maccaferri Gabions can accommodate significant differential settlement. The mesh baskets form a monolithic structure that acts as one homogeneous unit, which is permeable and suitable for use in high stress hydraulic applications.
To minimise road closure timeframes a number of projects have been completed utilising Maccaferri gabions which have been prefilled nearby and then lifted into place.
For reinforced slope systems and mechanically stabilised earth walls Maccaferri Terramesh and is a versatile, modular system that can be a more cost effective solution than the mass gravity Gabion wall because of the speed of installation and reduced rock fill requirements.
For mechanically stabilised earth slopes and embankments that require a vegetated front face, Maccaferri Green Terramesh can be filled with soil and planted, creating a green slope.
For high walls with high loads our Keystone TW3 system maxmises the use of available landspace in commercial developments.
For slope and wall reinforcement Geofabrics offers a suite of solutions including:
To respond to the different problems associated with instability of rock faces, Geofabrics has a broad range of independently verified rockfall mitigation systems designed and manufactured by Maccaferri. The range includes:
Double Twist Mesh and Steelgrid HR drapery systems offer significant flexibility in anchor positioning, saving time and cost on site.
For applications where low deflection and high strength are required, High Energy Absorption (HEA) Cable Mesh Panels offer containment of unstable rocks with minimal deformation.
When a drapery systems cannot be installed due to access, topographical or economic considerations Dynamic Rockfall Barriers/Catch Fences offer a rockfall protection solution for intercepting and stopping falling rocks and boulders.
In situations where there is available “run-out” space beneath a rockfall barrier in which the rocks can ultimately stop or be collected, Hybrid and Attenuator Systems combine the energy absorption capabilities of a dynamic rockfall barrier with the reduced maintenance advantages of drapery mesh on slopes.
Rockfall embankments provide protection to infrastructure and property over of a wider area than barrier fence systems. They are also able to contain or divert larger volumes of rock falls than stand alone barrier fences. Rockfall protection embankments are ideal solutions where it is not possible to intercept or prevent falling rock.
Concrete Canvas is increasingly being used as an alternative to non-structural shotcrete to protect slopes from surface erosion caused by weathering, surface run-off and environmental degradation.
In certain applications Concrete Canvas can be used as structural slope stabilisation by combining it with steel mesh and soils nails.
