How to fit a basement dig through a 660mm alleyway
To dig out a basement underneath a flat near Bristol city centre, a local building contractors had to remove tonnes of spoil through a narrow alley – one of the smallest spaces they had ever had to work in.
The project in numbers
Site only accessible via a 20m long alley that narrows to 660mm
2 x Easikit™ 300 modular conveyors: 12.1m and 10.9m
220m3 of spoil to be excavated
When a local building contractor was called in to add a floor underneath a flat near Bristol city centre, they faced an unusual challenge. The contractor needed to remove tons of spoil but the site was only accessible through a 20m long alleyway that narrowed to 660mm. The team needed a solution that would get the job done quickly, effectively, and safely.
On a job like this, with tons of spoil to move, the team would normally use cranes, diggers, dumpers, and other excavation equipment. Yet, with such a small space to work in, another solution needed to be found.
Initially, moving the material by hand was considered and priced up but the passageway was too narrow even for a wheelbarrow. Not to mention that the digging teams would almost certainly be exhausted.
From a health and safety point of view, this project was a minefield. Shifting all the soil, working in enclosed spaces, foot traffic impediment, repetitive motion, and lifting the barrows of bricks and soil into a skip would all increase the risk of injury to the labourers.
