Abweb is a three dimensional cellular matrix designed to strengthen weak soils in horizontal applications such as access roads, car parking areas and site compounds
Abweb strengthens and reinforces granular stone layers such as sub-base by confining the aggregate and providing a three dimensional tensile matrix.
Using this inexpensive system it is possible to reduce the thickness of aggregate under loaded areas by up to 50%. This reduces the volume of aggregate required and also reduces the volume of excavation.
Abweb provides reinforcement of granular stone layers in all civil engineering applications, particularly beneath permanent or temporary roads and tracks. It is especially useful where site access is restricted or availability of good quality crushed stone is limited.
The use of geocells in providing a flexible and permeable surface above tree roots is advocated in Aboricultural Practice Note 12 (APN12).
Within the root protection zone of existing trees the preference is for a no dig solution to any pavement required. Using Abweb allows pavement construction without the requirement for excavation whilst still creating a stable surface allowing vehicular traffic over the root zone.
Abweb reduces the vertical load on sub soils around tree roots and prevents damage whilst still allowing the free flow of water and nutrients into the roots.
