Case study - Flood repair
Retaining Wall (Grasmere)
- Following flooding in 2015, repairs were needed to a retaining wall which supported a vehicle bridge and outbuilding.
- Initially we needed to underpin the stone outbuilding and bridge to allow us to work underneath the structure without the risk of it collapsing into the excavation.
- Construction was then undertaken of a cofferdam to allow us to build the reinforced concrete foundation below the riverbed. Following this we erected shutters to enable us to cast an insitu reinforced concrete wall tied into the reinforcing of the foundation We backfilled the area with appropriate drainage and built a stone face to match the existing bridge parapet. The work was carried out under supervision on behalf of the land owner's insurance company.
- A major factor in the success of this project was due to how we overcame the logistical limitations of the access arrangements to the site. Situated at the end of a narrow lane on the fells above Grasmere with no access for wagons or large machinery. We overcame this by double handling material, using suitable small machinery and a large amount of physical effort.
Case study - Flood repair
Retaining Wall Repair (River East Allen)
- Floods had washed away the old retaining wall and large part of the garden.
- We needed to excavate the damaged area, store on site, reinstate a stronger more as a permanent solution
- A new reinforced concrete foundation was constructed beneath the river bed. A more durable retaining wall was constructed using blocks with a stone face and reinforcing continuing from the foundation to the top of the wall. We backfilled the garden area with excavated material, then walls and railings were installed before turf was laid. The work was carried out under the supervision on behalf of the land owner's insurance company
- Produced not only a strong, robust retaining wall that will not be washed away by any further flooding but it also has aesthetic appeal which exceed the customers expectations.
Case study - Flood prevention
Landslip Repair (Allendale Town)
- After repeated high water levels in the stream, a consultant structural engineer was employed by the client to design a structure to prevent further erosion by the water course which was causing a landslip risk.
- We needed to excavate the damaged area, construct the foundations for a gabion wall below the riverbed to prevent further undermining by the stream. Construct 3m high gabion wall.
- We carried out a temporary diversion of the stream to allow a foundation to be constructed beneath the bed of the stream. A 3-metre high gabion wall was constructed for the length of the client's property boundary using 150 tonnes of imported gabion fill. All the material was brought in using tracked dumpers due to the access problems.
- The work prevented further landslips.
Case study - Concrete slab project
Laying concrete slab for heavy forklift in haulage yard following flood damage (Hexham)
- An existing tarmac yard was lifted by flood water.
- We needed provide a concrete surface that would be resistant to further floods and suitable for large forklifts to load 44 ton wagons.
- We excavated to a depth of 500mm and laid 300mm of hardcore and 200mm of concrete with 2 layers of reinforcing.
- This resulted in a smooth and robust surface suitable for large forklifts.
