Earthworks & Drainage
Raymond Brown has over 50 years experience of operating plant and undertaking earthworks. It has considerable expertise in this area operating across a wide range of market sectors.
Highly qualified and experienced technical and site management teams address the key aspects of the work and activities, including environmental and ecological constraints. We maintain a significant fleet of modern plant, specialist earth-moving equipment and latest GPS technology. It operates excavators up to 35t, LGP GPS dozers, 30t dump trucks, compactors and crushing and screening equipment.
Allington Lane Embankment
The works comprised the stabilization of the embankment at Allington Lane, Eastleigh, where we are the main earthworks supplier for Osborne. The contract was delivered under Osborne’s MFF with Network Rail. The works included installation of sheet piles on both sides of the embankment over a length of approximately 160m, re-grading of the embankment and installation of drainage and fencing. The works were carried out on both sides of the rail track simultaneously.
During the contract, 9.5m long sheet piles were installed whilst the rail tracks remained operational with trains running at 70mph. An open line working procedure was developed working in partnership with Osborne and approved by Network Rail.
The sheet piles were installed using a Movax attachment that made the open line working possible and safe and also reduced installation time for the sheet piling element.
Over 14,000T of material was imported to site. The site team value engineered the project and the construction methodology and achieved a zero waste percentage of materials off site by incorporating all the temporary materials into the permanent works, subsequently reducing CO² emissions on site.
The project received the divisional Right Works Award for high standards in site and works management.

These works are to stabilise a cutting and comprise the installation of soil anchors and rock netting, regrading the slopes and the removal of vegetation.
There are a number of challenges associated with the project including working adjacent to the live railway, rope access works, dealing with asbestos, overhead power lines and the presence of badger setts in a protected woodland setting.
The cutting slope exceeds 35 degrees with exposed sandstone beds and boulders likely to have come from earlier rock falls of undermined bedrock.
This £1m earthworks project to reinstate a railway cutting near Sandown on the Isle of Wight. This cutting slipped early in 2014.
The works are being undertaken during a blockade of the line and include removal of the temporary works installed in January 2014, the installation of sheet piling, benching and re-grading of the cutting and installation of a drainage system to the failed section of the cutting.
