The Specialist Buyers Guide for Professionals in The Landscape Industry
Russetts Developments Ltd, have thirty years of experience in providing solutions for most forms of water containment.
Russetts Developments Ltd fabricate, supply and if required install various single-ply waterproof lining membranes such as EPDM and Butyl rubber, PVC, Polypropylene and TPO. This can be in the form of the humble garden pond, box-welded pond liners for formal ponds right up to lakes and agricultural slurry lagoons.
Russetts Developments Ltd also supply waterproof membrane linings to steel fire protection and potable water storage tanks of all capacities along with the waterproof membrane lining of above and below ground concrete tanks.

Russetts were recently involved in job at a private house to line a large pond that had a bridge over the middle. The lining had to be made in two pieces which were then fabricated together under the bridge using a small hot bond machine. The hole was firstly lined with underlay, then the two liners were pulled into place either side of the bridge. A small piece of liner was used under the bridge to connect the two larger pieces together using a fabrication machine. Russetts can manufacture multiple panels and fabricate them on site to line very large ponds and lakes.
Russetts Developments were contracted to repair a leaking pond which formed part of a lake that flowed into two water features located in the Botanic Gardens at the University of Bristol.
Part of the lake included a pond for aquatic and bog plants. The pond was an awkward shape being narrow and shallow with sloping sides. The existing concrete structure had cracked and the pond was leaking and was therefore in need of re-lining. Russetts achieved this by first lining the pond with a 400g/m2 geotextile protective underlay to protect the liner during and after installation.
A chase was cut into the concrete 200mm from the edge and below the water line. Metal flashing strips were riveted on and the membrane was attached to them.
Flagon GeoP 1.2mm TPO membrane was cut and shaped on site to custom-fit the shape of the pond.
Russetts was approached in 2011 regarding the refurbishment of Buscot Park’s famous Grade II listed Peto water garden feature, which consists of a series of formal ornamental ponds, weirs, cascades and canals.
The brief was to install a suitable pond liner ensuring it terminated at water level to avoid covering the original stone features. Due to the shape and 135m length of the water feature, it meant that the liner would have to be completely fabricated onsite to ensure a perfect fit. It was decided the most suitable material to line the water garden feature was 1.2mm Flagon GeoP TPO membrane with 400g/m2 protective geotextile underlay.
Once the water feature had been drained and cleared a 3mm chase was cut into the existing stone work at water level around the entire circumference of the feature. This chase would allow an L shaped laminated metal strip to be inserted inside the chase and hang vertically down the wall allowing the Flagon TPO membrane to be welded to it. The chase was then sealed with a waterproof and fish friendly mastic sealant.
Each section of the water feature was completely finished by welding in the base sheets and sealing the liner at water height before moving onto the next section. The base was mechanically secured to the original structure to ensure there was no uplift of the liner as there was no guarantee that water would not seep in under the liner through the original construction in adverse weather conditions. The Grade II listed status would not allow any modern sealing solutions to be applied to the original construction of the feature which would now be preserved under the new lining system.
The interlinking weirs were lined in preparation for new concrete flag stones to be place on top allowing the water to cascade into the section below. Each section had a 25mm dia pipe protruding through each weir with a removable plug to allow draining of each section if required. RDL’s experienced installers were able to fabricate the pipe sleeves using off cuts of the Flagon TPO lining membrane thereby reducing the overall costs of the project by not having to purchase expensive pre-formed sleeves.
The installation of the 1.2mm Flagon GeoP TPO lining membrane took a total of thirteen days from start to completion. There was no disruption to the surrounding park features as all the preparation of the lining materials and fabrication was carried out within the boundaries of the water feature. Approximately 1100m2 of Flagon TPO membrane was used.
On completion of the installation there was some remedial work to be carried out by Buscot Park grounds staff before was the water could be turned on and the famous Peto water garden feature including the Dolphin bronze fountain was put back into service which was just in time for the seasonal opening for the visiting public.
Russetts Developments Ltd supplied EPDM 1mm pond liner and Geotextile underlay for the lining of an established natural garden pond which was no longer able to retain water. The pond was cleared of vegetation and stones, a trench dug around the edge of the pond to secure the liners in place followed by the installation of Geotextile and EPDM liners. The project also required onsite fabrication of the pond liners to join a narrow section under the bridge with the two large ponds on either side.
