COURTYARD DEVELOPMENT, WARRINGTON

This project in Warrington was originally proposing to install crushed concrete (MOT/6f2) aggregate to fill a courtyard in a housing development in the North West of England. It was discovered that with access limitations to the courtyard, crushed rock aggregate being barrowed through the property would have posed a serious risk to the new building development.

Scott Raftry, Operations Manager at DWM Plant Ltd “We needed to install backfill material within an internal courtyard after the completion of a nursing home. Looking at the alternatives such as MOT/6f2 would have required serious lifting capabilities and a large crane to place then excavator to move the material around within the courtyard.”

Over 120m3 of Leca Lightweight Aggregate (10-20mm) was delivered through using 3 x deliveries onto a delicate and difficult to access residential area. This particular project would have required an additional eleven deliveries to carry the crushed concrete. Thus cutting back on Co2 emissions, cost and protecting the surrounding environment as a result.

FACTS

Amount of material: 120m3 of LECA LWA (10-20mm)

Interesting Fact: It was discovered that with access limitations to the courtyard, crushed rock aggregate being barrowed through the property would have posed a serious risk to the new building development.

Delivery Method: Pneumatic Delivery

Main Contractor: DWM Plant Ltd

Overview of Project

Through using our pneumatic blowing delivery for this project, capable of carrying on average 55m3 per load. The vehicle was able to blow distance of up to 40 metres – this allowed the Leca Lightweight Aggregate material to reach the central courtyard with ease and allowing greater flexibility and aiding environmental consideration to a variety of access and constructional challenges.

Scott Raftry, Operations Manager at DWM Plant Ltd “Leca lightweight expanded clay aggregate was very easy to install with minimal man power. Saving on time and labour. The success of this project has meant that we will always consider Leca Lightweight Aggregate for this type of project.”
