Tees Barrage - Gate 1 Refurbishment, Stockton-On-Tees
The Tees Barrage, was constructed in the mid 1990’s, and was formerly opened in 1995 to control the flow of the River Tees in Teeside. Its purpose is to prevent flooding to Stockton-on-Tees and accommodate tidal changes.
Tees Barrage comprises of 4 barrage gates, each 13.5m span by 8.0m deep and weighing approximately 50 tonnes. Each gate is mechanically operated on a bottom pivot pin arrangement and is opened and closed by a single hydraulic cylinder connected to one side of the gate.The gates are not only utilised to impound the upstream water but can be fully raised to give a sea defence during high tides.
May Gurney were awarded the Canal & River Trust PFI contract to maintain a number of inland Waterways. After approximately 17 years of operation and following May Gurney’s inspection, findings revealed that Gate 1 was not correctly functioning as originally designed. Subsequently Ekspan were commissioned by May Gurney to undertake the refurbishment of Gate 1.

Refurbishment of mechanical components to Gate 1
Ekspan were commissioned to undertake the removal of Gate 1 mechanical components to enable a thorough inspection. Following the inspection, Ekspan’s findings revealed there was excessive wear to the gate pivot pins, bearings and clevis bores. The submission of inspection reports and recommendations, by Ekspan, resulted in additional instructions to carry out further refurbishment work for the Gate. The works involved very complex jacking both in the vertical and horizontal planes and working in confined spaces within a marine environment.
Whilst successfully carrying out these works within budget and on time, Ekspan also ensured that all planned operations were in compliance with the Environment Agency and KGAL, who acted as Canal & River Trust’s design engineers.
