Ground Stabilization for Construction

Very often weak soils require foundation soil improvement so that heavy construction machinery or drilling rigs can operate. Conventional soil replacement is feasible only for shallow depths if with low water tables and increases the carbon footprint of a project.

PRS-Neoweb geocells (the Tough Cell®) are a more economic and sustainable solution for working platforms. One of more layers of PRS-Neoweb filled with granular material create a semi-rigid, ground foundation mattress that:

A PRS-Neoweb working platform simplifies the construction of embankments, as it they are laid and progressively filled in-situ with granular material. In addition, the stiff PRS-Neoweb working platform increases the reinforcement factor of PRS-Neoweb geocells used in the upper structural layers.


  • Distributed lateral stress increases shear strength of confined soil, creating stiff mattress
  • Low lateral deformation due to high hoop strength of PRS-Neoweb geocell
  • Friction resistance lowers stress reaching subgrade
  • Improves bearing capacity
  • Excellent drainage – can be used in saturated environment
  • Improves performance of PRS-Neoweb in upper layers
  • Eliminates expensive and time consuming soil replacement
  • Lowers project carbon footprint
  • Reduces embankment layer thickness to save aggregate
  • Fast and progressive construction
  • Reduce aggregate expenditures and earthmoving
  • Efficient for use with concrete infill
  • Cost-effective


Site conditions may require prior improvement of the bearing capacity for the heavy construction equipment. The PRS-Neoweb solution is to construct a raft foundation/ mattresses from one or more PRS-Neoweb geocell layers infilled with granular material. The rigid layer creates a working platform enabling construction equipment to move on solid ground by effectively increasing the modulus of the soft soil. This greatly simplifies the embankment construction process as it is erected and progressively filed in-situ with granular material that forms a rigid platform for working.
