Aarsleff Ground Engineering have completed on site in Clay Cross, Chesterfield installing retaining walls for a new housing development.
The Egstow Park development will have over 160 houses on the site, ranging from two-bedroomed homes all the way up to four-bedroom. The development is also located with good transport links into Chesterfield, along with great outdoor space and only a short distance from the Peak District.
Aarsleff were awarded the contract by St. Modwen Homes for the construction of the retaining walls on the site. Aarsleff proposed a King Post Wall solution as an alternative to the sheet piled wall St. Modwen Homes were originally looking for as it provided a faster construction and more aesthetic finish.
In total, Aarsleff installed 106 Lin/m of King Post Wall around part of the site with maximum retained heights of up to 2.6m. The construction of the wall involved driving H-section posts spaced 1.5m apart using a crane suspended vibratory hammer. Once installed, the pre-stressed concrete panels were placed between the posts to create the wall. The wall was then back filled to retain the bank and allow maximum usage of the site.
