Installation Guide - Load Support _v2021.3a

Overview
This guide describes the procedures for installing PRS Neoloy® Tough-Cells (formerly known as PRS-Neoweb) in load
support - pavement applications. The following are the basic stages:

     •   Tools and handling
     •   Site preparation
     •   Layout sections
     •   Fasten sections
     •   Anchor stakes
     •   Expand sections
     •   Infill
     •   Special situations
                                                                             FIGURE 1. TYPICAL INSTALLATION


Key Points before Starting
1.   Materials – ensure that all specified materials and the correct Neoloy Tough-Cell type/width are delivered to the
     site, undamaged, and ready for use.
2.   Tools – verify that you have the appropriate materials and required tools – such as, anchors, pneumatic stapler
     (and staples), air compressor and electricity source; geogrids and geotextiles as specified.
3.   Plans – make sure that you have approved project construction plans and specifications.
4.   Layout – when laying out the Neoloy strips, make sure the sections and cell openings are in the direction,
     alignment and elevation as shown on the construction drawings.
5.   Empty cells – do not walk on exposed cells. Although the cell walls are stiff, Neoloy Tough-Cells are a composite
     system that works only when infilled with soil. Walking on empty cells may bend the cell walls and damage the
     performance of the system. Use boards and planks to walk over empty cells if necessary.
6.   Vehicles – vehicles may not be operated directly on exposed Neoloy Tough-Cells at any time; during the infill
     process make sure that the Neoloy Tough-Cells are not damaged by mechanical equipment.
7.   Safety – ensure that employees are familiar with and adhere to safety standards and procedures.
8.   Environment – if natural stream environments are involved, minimize environmental impacts of construction
     activities on fish habitat, sediment, pollutants and bank vegetation, in accordance with relevant guidelines.
