Green-Stay Ground Reinforcement Blocks

The revolutionary development in ground reinforcement

Introduction

GRB is a new and revolutionary development in ground reinforcement. It is tough, flexible and easy to install making it the professional choice for a wide range of construction projects.

Manufactured from 100% recycled material GRB is the environmental and sustainable solution of choice to prevent ground erosion.  The honeycomb tiles provide an interlocking system that can be laid at ground surface level and then either filled with stone, gravel or earth or it can be seeded.

Use GRB to create the ultimate, hassle-free driveway - it prevents gravel migration and will keep your drive rut free resulting in a maintenance-free area with high aesthetic appeal - qualities that also make it perfect for green car parks and construction projects

 Installation Instructions

The following instructions are intended as a guide only, in general, the same preparation procedures used for traditional paving solutions as used in the construction of footpaths, driveways and access routes should be adopted. These guidelines assume that a sub-base is to be used beneath the paving system.

  1. The area to be protected should be marked out and excavated to the following depths depending upon the final use. Remember to add the depth of the GRB to the figures quoted if the GRB is to finish flush to the surface.

Project

Typical Depth

Patios, Garden Paths

75 - 100mm

Driveways, Public Footpaths

100 - 150mm

Heavy Uses

150 - 225mm

Highways

150mm+

  1. Once the full area is excavated the sub-base can be installed. Compact the full area to be as level as possible using either a vibrating plate or for larger areas a vibrating roller

  1. A thin 40mm layer of sharp sand/soil mix should be laid over the sub-base to level out any imperfections or hollows in the surface of the sub-base. If the area is to be grassed this mix will provide a suitable substrate for grass root survival and growth.

  1. Once the area is level the GRB can be interlocked and laid. The GRB is delivered in Any GRB's that need to be cut should be measured and cut before installation where possible leaving full, complete cells along the outer edge.

  1. The area can then be backfilled with the medium to be used. If using gravel we recommend the use of 10mm or less as this will ensure better filling of the cells. If the area is to be grassed, we recommend using a 70/30 root zone mixture; this will prevent the hard compaction of the cells which could be associated with just using topsoil which would limit grass growth. Initially fill to about 10mm below the top surface of each grid as this will protect the grass in its initial growing phase. The whole area can then be seeded and watered.

  1. An optional weed suppressant membrane can be used on top of the sub-base before applying the sharp sand as this will prevent weed growth but will allow for natural drainage of rain water to the ground below.

  1. Please note that as with all forms or paving products it is essential that the edges of the GRB are laid flush to avoid creating any tripping points.  This is the responsibility of the installer and Green-stay accepts no responsibility for injuries caused as a result of in-proper laying.
