A process that will modify and stabilise in-situ material categorised as unsuitable by external influences (high moisture content, low bearing capacity) into suitable engineered material, so eliminating the need for disposal off site and the import of general and engineered fill. The engineered material is tested for improved bearing capacity and compaction, in accordance with the end-product specification.

Enviro-fill Site won material 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 time, providing the contractor with greater flexibility in the earthworks programme. Treated material can generate bearing capacities of 5% CBR or 100KN/m2.

Enviro-cap Site won material can be modified 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. Treated material can generate bearing capacities in excess of 15% CBR or 200KN/m2.

Enviro-base Site won material can be stabilised using a variety of binder agents to provide an even further enhanced engineered material to a Subbase specification (800 Series S.H.W.), this material can be non-frost susceptible so allowing the pavement construction to be overlain directly onto the stabilised layer. Treated material can generate bearing capacities in excess of 30% CBR or 300KN/m2 E

Enviro-lock A process that eliminates the need for ‘dig and dump’ of contaminated material. Contaminated in-situ materials (typical containments: heavy metals, hydrocarbons) can be locked via stabilisation/solidification into the host material using various binding additions. The locked material is tested to confirm permeability and eluate levels have been reduced, to comply with the end-product specification, in accordance with the site remediation strategy
