Our unique equipment and understanding of vital but endangered environments means we have become wetland experts.
Our amphibious equipment ensures that we can work in terrain where nothing else will do.
We provide a cradle-to-grave service including growing and providing aquatic plants, training volunteers to carry on planting and further enhancement works. Visit the Terraqua website for more information.
A recent example of our work in wetlands is a project for Natural England that we started at the end of 2016. We removed approximately 55,048m3 of sediment from Hoveton Great Broad, Hudson’s Bay (imagine taking a metre of material from seven Twickenham-sized rugby pitches), to deepen the lakes.
Hoveton Great Broad is one of the largest yet most secret lakes in the Norfolk Broads. It’s a key part of an internationally important wetland landscape and is entirely man-made.
The sediment removed was used to create new areas of fen within Hoveton Great Broad (making this a waste-free project).
This was achieved by using geotextile tubes to create bunded areas.
Reed areas were created and the waterline along the banks of shallow waters were restored. The restoration involved the construction of new banks (retaining structures) and in-lake disposal areas (fen or backfill areas).

Breaching the seawall flooded the wetland we'd created when we built new tidal inlet channels with footbridges for the coastal path. Around 35,000m3 of material was moved and 3,000 tonnes of rock-armour scour protection was installed.

We transformed a brownfield site into a diverse and complex habitat that included lakes, ponds, wetlands, boardwalks and bridges, pond dipping and educational facilities, carparks and ancillary infrastructure including a reed-bed effluent-treatment system.
Working with the society from the outset, we tailored the works to a fixed budget.
