Lakes and Ponds

W.J.Hatt has been undertaking pond and lake construction and renovation since 1937. Over the years we have accumulated three generations’ worth of experience, creating long lasting water features and wildlife habitats. We carefully build these to suit their surroundings and look very natural.

We offer a complete design and build service for our lakes and ponds. As part of this, we obtain the necessary consent from the environment agency and ensure that local planning requirements are met when needed.

We carry out much work on large estates for conservation and wildlife needs. We also construct and renovate a huge variety of projects for local authorities and private clients alike. This work includes building ponds and lakes into clay or the water table, as well as using impermeable butyl liners or puddled clay.

Wildlife Ponds
We construct our ponds and lakes in such a way that the butyl liner is 'shelfed' into the banks. With this method of construction no liner is ever seen above the waterline.
Further information on lake construction

Jack Hatt, who founded the company, was a passionate angler; this is where his love of waterways originated. That passion has carried on down the generation of Hatts, leaving Oxfordshire and Berkshire with a huge range of ponds, lakes, streams, rivulets, cascades and waterfalls. These range from more modern angular constructions to rustic nature reserves. The company operates a unique way of constructing ponds and lakes using butyl liners. While the liner itself is not visible it also provides a planting shelf that goes right down into the water


When any waterway stops holding, the problem becomes exponentially worse as the leaking water enlarges and washes away the hole further and a vicious circle begins. To stop this quickly, W.J.Hatt installs piles of the correct length and size. These piles can also be hidden under the soil so that the repair appears completely natural. Piling provides a relatively straight forward method of introducing almost any size of traditional oak board sluice gates back into a water system.
