Overview
As part of the early-stage infrastructure for a 24-unit residential development, a temporary car park and compound was constructed on site. Given the requirement for a reliable, regulation-compliant sub-base with fast turnaround and consistent supply, the choice of material was critical in enabling the site to proceed without delay.
Project Scope
The project required a high-quality, SHW 803-specification sub-base to construct a car park and compound that would facilitate access and operations during the full development cycle. As the area would be deconstructed at the end of the project, efficiency, cost control, and product reliability were non-negotiable.
Material Requirements
We supplied 1,334 tonnes of Type 1 Ecoblend® CA from our Greenwich depot, laid to a depth of 100mm. Ecoblend® CA was chosen due to its:
- Superior product quality
- Material cost savings
- Ready availability

Environmental & Economic Impact

Circularity
Equivalent to over 5,929 tonnes
of municipal waste diverted
from landfill

Sustainability
1,337 tonnes of critical
natural resources preserved

Material Efficiency
270 tonnes of material saved

Transport Efficiency
Material savings eliminated
the need for 28 additional
lorry movements
Outcome
The use of Ecoblend® CA delivered a high-performance sub-base that allowed works to be completed ahead of schedule. Lightweight deflectometer (LWD) testing confirmed surface stiffness met highway specification standards. The client praised both the material quality, and the hands-on technical support provided during site operations.
“The site foreman was impressed with the visual quality of the product. Deliveries were swift and on time.” – Client
