Description
Firmaweb Ground Stabilisation system is a three dimensional honeycombed network of perforated / textured cells to confine and redistribute loads and control erosion; quick and simple to install, it can be used for embankment stabilisation, road and rail construction, water courses, armouring, footpaths, and retaining walls. Firmaweb can increase material sheer strength, reducing fill requirements by up to 50%, and it’s cellular structure can improve soil bearing capacity by up to 17 times. The ground stabilization ranges also includes Alderway and Geotex geotextiles and Secugrid polyester grid for ground reinforcement.
FirmaWeb reinforcement structure acts as a cellular confinement system for all granular infills. Unlike other systems, FirmaWeb uses the confinement of infills to provide load support and erosion control for many situations. Once filled, it provides a stable surface for both pedestrian and trafficked areas such as driveways, paths, car parks, golf courses and artificial surface sports fields.
SUDS – Sustainable Urban Drainage System
FirmaWeb cellular confinement system, can be used as a porous ground layer in many situations. The porosity of the perforated cells, combined with the porosity of the loose infill material, allows water penetration both vertically and horizontally making FirmaWeb the ideal choice for sustainable urban drainage system (SUDS) applications. Unlike typically saturated ground, FirmaWeb retains the structure of the surface by reinforcing and containing the infill, stabilising the ground and preventing erosion/ subsidence.
Slope Protection
When used on slopes, FirmaWeb confines and reinforces vegetation by increasing the natural resistance to erosion. On non-vegetated slopes it prevents the down slope migration of the infill, resulting in an overall greater stability across the slope. When used on channels, riverbeds and swales, FirmaWeb increases the shear strength of the selected infill against the fl ow of water. The water is directed above the infilled cells, allowing the rootzone to remain undisturbed. FirmaWeb provides an attractive and economical alternative to concrete lined channels, or can be used within concrete to create a flexible concrete slab with inbuilt expansion joints.
Tree Root Protection
Taking its use as load support, FirmaWeb has become the way to protect tree roots from the pressures of traffi cking and loading from above. Whether it be to protect a new sapling, or to introduce protection for a fully established tree, FirmaWeb can provide the relief needed for the roots to thrive. By using the load redistribution features (load support information p6) to evenly spread loading,
FirmaWeb reduces point loading and the associated pressures on tree roots beneath. By confi ning the soils, lateral movement is prevented, and the ground is stabilised, keeping a fl at, fi rm ground in place and stopping compaction of sub-soils, which put greater pressure on tree roots. Beneath the FirmaWeb tree roots are free to grow, and the relieved pressure promotes the migration of both water and nutrients, which eventually ensures the long-term preservation of the tree itself. How does it work? • Protects tree roots from the pressures of loading. • Offers protection without the need to prevent access by foot or by vehicle. • Promotes the migration of water and nutrients. • Eventually ensures the preservation of the tree.
Earth Retention
When layered, FirmaWeb can retain earth by confining the soil face and preventing it from falling or being eroded. The exposed horizontal edges of the FirmaWeb structure provide space for vegetation to flourish, as well as platforms for rainwater capture.
Load Support
As a road base reinforcement system, the FirmaWeb honeycombs spread loading across the extent of the cellular confinement. The cells behave like a stiff, yet flexible horizontal laminar element beneath the supported load bearing surface. By isolating and supporting the load bearing surface from the softer subgrades below, FirmaWeb successfully solves load bearing problems and provides a subtle and invisible finish to all surfaces.
By providing additional reinforcement to infill materials, FirmaWeb reduces infill requirements by up to 50%, reducing excavation depths and saving both time and money
The size of Firmaweb supplied depends on the number of cells per sq/mt and the price depends on both the number of cells per sq/mt and the depth of the cells . There are approximately 40 different permutations , please call for price and any advice on specification.
