Timber Basin Glasgow
Client: WA Fairhurst Consulting Engineers, I and H Brown Contractors
Project Brief: The housing developer required a continuous "soft margin " to the the new
edge of the canal as a result of creating a new level building platform. British Waterways wanted a stable reed margin frontage. A grassy slope bank was also to be created to cover the knotweed control fabric used at the top end of the site.
The Solution: Pre-Established Coir Rolls were installed as a line to define the outside edge of the slope. Where the water was more than 300mm deep the Coir Rolls were placed on top of a faggot so that the plants did not start submerged. Where there were gaps behind the Coir Rolls the infill soil was covered with a Pre-Established Plant Pallet of reeds.
At the far end the exposed knotweed fabric was covered with a layer of soil secured by placing the soil in Salix Cell, a 3 dimensional synthetic honey comb cell system. This system guarantees a consistent soil depth and prevents slumping. The soil was seeded and covered with NAG C125, a soil blanket that provided improved germination and erosion control.
The Result: The
canal edge of the site had a soft but secure edge with habitat and landscape value.
Materials used: Pre-Established Coir Rolls, Pre-Established Coir Pallets, Faggots, Salix Cell 35/10, NAG C125
