Truckpave® Case Study: Malvern Wells, Worcester : P. Forker Ltd / Severn Trent Water
Truckpave Surface Grass Reinforcement
Access for water company vehicles through agricultural land
The Challenge
The construction of a CSO (combined sewer overflow) on agricultural land, in Malvern Wells (Worcs), presented Severn Trent Water's engineers with challenges:
- Provision of future access for maintenance vehicles, with minimum visual impact on the landscape.
- Design of an access road and turning area that was both permeable and able to handle overrun and manouevering by heavy commercial vehicles.
For many years, Severn Trent have been successfully using Hoofmark's 38mm deep Golpla grass pavers to provide access to their installations and were happy for Golpla to be installed along the main access road on this project.
Their engineers were concerned about the possible effects of heavy vehicles manouevering on the turning area at the end of the access road – it was thought that this might cause rotation of individual pavers, potentially leading to displacement of units.
Truckpave Solution
Hoofmark's Truckpave grass paver system, 100mm deep and also manufactured from recycled plastic, was selected to provide a permeable surface capable of withstanding the stresses imposed by the turning movements of heavy commercial vehicles.
self draining access road for commercial
vehicles - minimum visual impact
In March 2008, working for Severn Trent Water, P. Forker Ltd formed the access road by the installation of some 690m² of Golpa 38mm deep grass pavers. The vehicle turning area was constructed using 360m² of 100mm deep Truckpave grass pavers.
Truckpave Construction Detail
Base: 300mm DfT clause 805 type 3 free draining crushed stone
Blinding layer: 30mm layer of sharp sand
Surface Material: Truckpave recycled plastic pavers. Unit size 600 x 400 x 100mm.
Cell fill: Top soil and grass seed
Client Benefits
- Truckpave units weigh only 12kgs each and are well within Health and Safety manual handling limits.
- Truckpave units can be laid by hand, thus avoiding the complications involved in mechanical placement and eliminating the possibility of disturbing the bedding.
- Permeable surface achieved, so no drainage issues.
- Unlike concrete units, Truckpave will not dry out cell contents or transfer heat during hot weather. This benefits grass quality and durability.
- Truckpave, being manufactured from recycled and recyclable plastic, is environmentally friendly.
- The supply cost of Truckpave compares favourably with equivalent concrete units.
- Amongst plastic grass paving systems, only Truckpave is capable of withstanding regular HGV traffic.
