According to statistics released by the Environmental Agency, one in six properties across England and Wales are at the risk of being swept under water by floods. And, given the recent projections on climate change, the Thames Barrier definitely has some tough work ahead to keep London’s head above water.
But it is no small feat to keep the massive, 3,300 ton gates prepped and patched up to spring into action in case of a sudden flood prediction. Constant maintenance and repair works are crucial for the barrier system to guarantee the expected performance levels.
Engineering contractors VolkerStevin has been doing a great job since 2005 providing maintenance and improvement works to the Thames Barrier. And, we are privileged to have been involved in the screeding part of the maintenance works for 8 piers of the Barrier.
CSC carried out the screeding using Sika waterproofing screed system – reinforcing Sika1 screed with PP fibres and bonding to concrete using Sikadur 32 bonding agent that was cured with Sika Hardcure 24.
Nearly 49 tonnes of sand (1960 bags), 393 bags of cement and the required screed additive, binding agents and equipment were transported in a barge to be lifted on to the pier by our client VolkerStevin. And, we are proud to have delivered the work on time and to high quality standards as expected.
The Thames Barrier was built in 1982, and is one of the largest movable flood barriers in the world. The barrier stretches across 520m of the Thames River near Woolwich, protecting an area of nearly 125 km2 of Central London from flooding due to tidal surges. The Barrier is run and maintained by the Environment Agency along with London’s other flood defence systems.
