Installing intertidal reed beds at Fresh Wharf, Barking
Fresh Wharf is a mixed-use, waterfront development on the River Roding in Barking, East London. A former Victorian fishing wharf, the suburb now supports modern residences, retail, large green spaces and direct transport links into the City.

We were contracted by Erith to install two inter-tidal reed beds within a former mooring area. Comprising 890 linear metres of A.G.A. Pre-vegetated Coir Rolls, together with 1100 linear metres of A.G.A. Rock Rolls, the awkward site on a tidal river presented the team with a series of obvious logistical challenges. With limited and difficult site access, our team had to optimise the delivery of material and machinery to ensure a safe unloading and working environment carefully in tune with the tidal timetable.
Intertidal reed bed cross-section
Designed to do much more than simply enhance the wharf visually and increase biodiversity, the reed beds help to control the level of silt suspended in the water, reducing build-up both in the main channel and downstream at the already shallow, Barking Creek.
On top of the existing compacted aggregate, we introduced 600mm of topsoil. The rolls were then installed in an alternate arrangement contained within an upper and lower terrace divided by oak sleepers. A line of two rock rolls were installed at the toe to tie in the capping beam and absorb wave impact. A combination of pointed wooden stakes and 3mm galvanised wire was used to secure the rolls.
