Stabilisation Project South Yorkshire

The benefits of this method are as follows:

• Reduced quantity of imported aggregates.
• Saving natural resources through reduction in quarry stone.
• Minimising use of recycled products.
• Reduction in potential waste material to dispose of at the end of a contract.
• More durable surface than aggregates.
• Increased strength over aggregates can be achieved.
• Reduced earthworks profile.
• More cost effective to construct than using aggregates.

A recent example of this was on a project in South Yorkshire where cement stabilisation was used to construct both the site compound areas and permanent site access roads and car parking.

For the site compound an area of 6000m2 was constructed by adding cement to the site won sand material. The cement was rotavated and compacted using in-house plant to a depth of 200mm to stabilise 1200m3 of material. This replaced the requirement to import 2600 tonnes of aggregate and removed the need to dispose of this material once the contract was completed.

Permanent works included 15,500 m2 of car parking and access roads. Given a working depth of 200mm this operation saved a minimum of 3100 tonnes of quarried product. Overall this project saved 5700 tonnes of import and approx. 285 HGV wagon movements.

VHE in-house resources undertake site investigation works, geotechnical soil analysis and through bench scale trials to ensure appropriate methods and additives are scientifically calculated to deliver the required end product based on the geotechnical properties of the existing subsoils in relation to the proposed end use.
