Granmat is a process that will modify or stabilise in-situ material categorised as unsuitable by external influences (high moisture content, low bearing capacity) into ‘suitable engineered material’. This eliminates the need for disposal off site and the import of general and engineered fill.
Benefits include:
Granmat provides three main areas of soil stabilisation:
In-situ soils which are deemed unsuitable in conventional construction processes can be modified via the addition of binder agents to produce an engineered material suitable for building on. The nature of some of the binder agents allows for the modified material to be stockpiled and then used over a period of time, providing the contractor with greater flexibility in the earthworks programme.
In-situ soils, as above, can be stabilised using a variety of binder agents to provide an enhanced engineered material to a ‘6F’ capping specification (600 Series S. H. W.), which will adequately replace the need to export site won material and source and import, crushed concrete or equivalent granular material in its place.
In-situ soils, as above, can be stabilised using a variety of binder agents to provide an even further enhanced engineered material to a ‘Clause 803’ Sub base specification (800 Series S. H. W.), this material can be non frost susceptible so allowing the pavement construction to be overlain directly.
