TPS have extensive experience in undertaking flood / coastal protection schemes.
Over the last 10 years we have undertaken major coastal defence projects along beachfronts in the Northwest. These involved the excavation and placement of rock armour, concrete blinding and mass in-situ concrete pours, all of which were completed under full tidal working conditions.
Due to the shape of new revetments and often the quantity of mass concrete pours required, we manufacture bespoke shuttering systems to optimise efficiency, ensuring maximum pours are achieved within restricted tidal shifts.
We have experience in the placement of PCC block and wall units, which are often required as part of new promenade / revetment construction.
TPS also undertake flood management schemes, excavating into existing river banks and installing protection measures through the installation of rock armour, filter stone, filter membrane and structural backfills under tidal conditions.

Rossall Coastal Defence Scheme
Employer: Wyre Borough Council
Main Contractor: Balfour Beatty
Form of Subcontract: NEC3 Option B
Value: £2.5M
Description:
The Rossall coast protection scheme replaced two kilometres of sea defences from Rossall hospital to Rossall Point, in a £63m coastal defence scheme that protects 7,500 properties from the risk of flooding. The scheme was completed in 2018, £6 million under budget.
327,000 tonnes of rock armour was used to create the base of the defences, to weather the harsh conditions on this exposed part of the coastline and allow the beach to build up in the area. Between the rock revetment and the promenade, specially manufactured precast concrete was used to form a stepped revetment to break the waves. The promenade has also been significantly widened.
An ecology park on the landward side of the defences was created and is known as Larkholme Grasslands. This strip of grassland, from West Way to Fleetwood Golf Club, is already classed as a biological heritage site because of the rarer species of flora and fauna that grow there. The area was enhanced to allow residents to enjoy the rich and diverse wildlife.

Anchorsholme Coastal Protection Scheme
Employer: Wyre Borough Council
Main Contractor: Balfour Beatty
Form of Subcontract: NEC3 Option B
Value: £1.5M
Description:
Anchorsholme Coastal Protection Scheme aims to reduce flood risk to 4,800 properties in Blackpool.
A kilometre of concrete sea wall has been replaced, maintaining access to the beach, and a new promenade attracts residents and visitors with views over the Irish Sea. The promenade also links the seafront to the nearby Anchorsholme Park, which has been redeveloped.
The scheme forms part of the Fylde Peninsula Coastal Programme, a partnership between Wyre, Blackpool and Fylde councils and the Environment Agency to reduce flood risk to people and develop historic and natural environments. Anchorsholme together with the Rossall project, forms one of the largest coast defence projects in the country.
