Riparian

Greenford Ltd began with and have long since specialised in riparian works on the canals, waterways and marinas of Britain. Greenford have an extensive history of water-related civil engineering, which includes creating and repairing bridges, embankments, towpaths, cycle-ways, walkways, waterway furniture, marinas, reservoirs and environmental improvement works amongst many others.

 

Bank Reinforcement Works, Elephant & Castle, Amersham, Berkshire

Greenford completed the bank and wall restoration works to the Elephant & Castle in Amersham, Berkshire mid-August 2017. The works involved the removal of the failed section of river bank followed by the reinforcement of the bank with sheet piling and the rebuilding of the brick wall. The project was completed with no disruption to the establishment’s trade or the neighbouring residential community.

Waterway Regeneration, Maidenhead

A decade in the making, the regeneration of the Maidenhead waterways is a project very close to the heart of local residents and businesses alike. The works started with the reinstatement of the waterway from York Road to the library footbridge section of the York Stream channel, and will continue up and downstream thereafter to complete Stage 1 channel works between the A4/St Cloud Way and the GWR railway line. The end result will be a navigable waterway which will be wide enough to accommodate leisure boats and will include a weir, fish pass and boat roller. The waterway ‘ring’ that will run through and around Maidenhead is set to make an attractive feature which will encourage new life to the town centre. This scheme was driven by Maidenhead Waterways and implemented by the Royal Borough of Windsor and Maidenhead’s Area Action Plan.

Bank Protection Restoration, Leicester Marina

In February 2017 Greenford Ltd completed a project to remove and replace 67 metres of failed bank protection at Leicester Marina. These works involved the temporary detachment of pontoons, removal of existing sheet piling, installation of new sheet piling and timber detail, and the reinstatement of the footpath the length of the bank.

 

Bridge and Brickwork Restoration, South Oxford Canal

As part of a £1 million 3 year initiative by Canal & River Trust, Greenford Ltd are completing the restoration work on the first bridge, Chisnell Lift Bridge (no. 193) near Anyho on behalf of principle contractor Kier Services. The work includes repairs to the brick and stonework, rebuilding walls and filling the numerous holes and voids that have appeared over the years. This section of works is on schedule for completion by Christmas 2016.

River Bank Repairs, Donnington Bridge, Oxford

The end of October 2016 will see the completion of extensive river bank improvements on the River Thames Longbridges, north of Donnington Bridge, Oxford. Greenford are completing these works on behalf of Skanska under the direction of the Oxfordshire County Council (OCC). Over time the existing towpath bank had slipped and was suffering quite severe degradation. These damaged sections of the river bank were removed where necessary to make way for the necessary repairs – sheet piles were driven down to water level into the original bank line and backfilled with clean hard-core stone and Gabion baskets filled with natural stone were then placed to form the new bank wall. Upon completion the towpath will be formed with a tarmac base topped with a tar and chippings finish. These restorative works on behalf of the OCC mean that this section of towpath will once again be able to be enjoyed by locals, pedestrians and canal craft users alike for many years to come.

Riparian Wall Repair, Waterside Inn, Bray, Berkshire

In 2014 Greenford conducted works to restore, repair and replace parts of the riparian wall which belonged to the Waterside Inn, Bray, Berkshire. The project was to replace a failed brick riparian wall which involved the use of a floating platform to gain access and to carry out the repairs whilst maintaining minimal disturbance to one of the top restaurants in Britain. Greenford worked to consistently ensure this three Michelin star establishment, which is owned by acclaimed French chefs Michel and Alain Roux, was able to carry on as normal during the construction period.

Canal Towpath Upgrade, Bath to Bathampton, Somerset

Greenford commenced restoration and improvement works to the canal towpath which runs the length between Bath and Bathampton, Somerset on behalf of the Kier Group, in March 2016. The works involve the excavation, widening and resurfacing of the towpath as well as ensuring the soft landscaping either side of the walkway is restored. The project has made the towpath easier to traverse, and more hard-wearing and attractive for both path and canal users alike. All major works on the project were completed July 2016.

Storm Relief Channel Restoration, Harlow, Essex

Greenford were engaged by the Harlow District Council in Essex to repair and restore an eroded storm relief channel riverbank. Some areas were already completely undermined and in desperate need of reparation. The banks were reinstated with the installation of Gabion Walls and mattress as well as upgraded drainage measures. Due to the level of erosion the project also included the construction of a new chain link fence, garden beds and lawn were restored and reseeded, and a brand new garden shed built and installed. Greenford started works in February 2016 and, despite adverse weather conditions, were able to perform the Harlow riverbank repairs quickly, to plan, and with minimal disturbance to the local residents.

Flood Alleviation Works, Ledburn, Buckinghamshire

January 2016 saw the commencement of flood alleviation works through the town of Ledburn in Buckinghamshire. Greenford are performing the works on behalf of the Buckingham and River Ouzel Internal Drainage Board (BROIDB) as part of their wider 2015/16 Watercourse Maintenance Programme. The work itself involves the excavation and replacement of the existing drainage culvert which runs through Ledburn and exits via a nearby watercourse. The works path runs through a road, public areas as well as several private residences. Greenford are working hard to ensure that all stakeholders are fully informed and all ecological aspects are constantly assessed and accommodated for during the entire project.

Erosion Protection, Startops Reservoir, Tring

In 2015 Greenford completed erosion protection works in Startops Reservoir, Marsworth, Tring in Hertfordshire. Greenford used 390m (1000tonne) of specialised loose stone to provide erosion protection to the shore line of the reservoir. This project offered limited site access and the works were therefore carried out by employing a combination of ferry and land based equipment. Coordination of the project also needed to take into account that an area adjacent to the works was a Site of Special Scientific Interest (SSSI), and to also ensure members of the public were considered and kept safe at all times.

Pedestrian Bridge Replacement, The Swan at Streatley

In 2015 Greenford completed works on a new pedestrian bridge at The Swan at Streatley, a country hotel and restaurant in rural West Berkshire. The original failed bridge needed to be replaced with minimal inconvenience to the hotel and also any vessels on the busy Thames. The new timber bridge has a 10m span and connects the bank to a small island berth. The works were difficult to complete given the lack of access to site and required materials and plant to be ferried from the opposite bank via various floating craft.

Scour Protection Works, Oxfordshire County Council

The scour of flowing water may erode structures and land and can be a serious issue if left unchecked. In 2015 Greenford performed scour protection works for the Oxfordshire County Council at various locations around the county. These works are imperative to maintaining the integrity of existing structures and land-based constructs which exist near to waterways. Greenford were able to deliver effective, compliant and aesthetically pleasing scour protections.

New Mills Marina, Peak Forest Canal, Derbyshire

The New Mills Marina overlooks Derbyshire’s magnificent Peak District and was a project set in motion April 2014 when Pridewater Estates signed a 50-year lease with Canal & River Trust for this then run-down marina located in the small picturesque, market town of New Mills. The renovation involved not only transforming every building on the site but also the berths, the internal road layout, picnic areas, security gates and fences, and the creation of two holiday apartments and a Caravan Club CL site. The project had to take into account many existing 19th century features, including the original, working wharf dating back to 1842 and two derelict buildings from the 1830s originally built to stable horses. Throughout the entire renovation the marina was kept fully functional and open to residential and leisure boat moorers.

Aylesbury Canal Society Marina, ‘Circus Field’

When the Aylesbury Canal Society’s old marina in the Aylesbury town centre was to be repurposed, there was a need to not only relocate the society’s headquarters but also to transform an unused field into a fully functioning marina with the capacity to moor, power and provide a secure environment for a large number of canal boats and the Aylesbury Canal Society’s new base of operations.

In 2013 Greenford Ltd took on this large scale project and, working to the society’s requirements, excavated, sheet-piled and clay-lined a fully functioning marina complete with docks, jetties, power bollards, out buildings, walkways, permeated tarmac footpaths, and concrete and brick structural supports and detailing. This project also included creating the impressive mechanical ramp and covered slip way which is partially housed in the lower levels of the new headquarters. Boats are able to manoeuvre onto the ramp from the water and then be towed into a covered, heated, secure space in which to conduct maintenance or repair works. Greenford also built a pedestrian bridge crossing the canal and an arm lift bridge which spans the entrance to the marina from the adjacent canal. This arm lift bridge has been constructed in such a way which enables it to be raised and lowered at the pull of a rope from the water’s edge making the canal entrance to the marina effortless and practical. Greenford worked to ensure this new thriving hub of the Aylesbury waterways is around to be utilised and enjoyed for many years to come.

Doghead Stakes Fish Passage reinstatement, Newbury

The project which Greenford Ltd commenced in 2014 at Dog Head Stakes Weir on the Kennet & Avon Canal, Berkshire was conducted for the sole benefit of the local flora and fauna. The Canal & River Trust engaged Greenford to reinstate the fish pass at the Dog Head Stakes Weir and introduce woody debris and channel enhancements to almost 2km of river. The aim of the works was to unlock a significant barrier to migrating fish and to restore the necessary balance to the local ecosystem.

Crick & Cropredy Marinas

Crick Marina and Cropredy Marina are both located in Oxforshire on the southern Oxford Canal. Initially the site was home to Crick Marina only, until Greenford were brought in for the design and construction of a new 250 berth canal marina in two basins on the Oxford canal at Cropredy, including a new access road, parking areas, jetties and paths around the site, followed by re-grading of surrounding agricultural land which was completed in 2013. Greenford are also responsible for the initial extension to Crick Marina in 1999, adding an extra 76 berths to the southern end of the basin and providing enough space to hold the inaugural Crick Boat Show in 2000.

Grove Lock Marina

Grove Lock Marina is located in beautiful rural Bedfordshire, a short distance outside of Leighton Buzzard. The transformation of this site was down to a combination of an attractive yet practical design and Greenford’s civil engineering efforts. This project involved the complete rejuvenation of the marina to include state of art berths, out buildings which include showers and toilets, a large car park, security gates, site office and supplies shop, ample picnic and barbeque areas, pump out and Elsan facilities, metered electricity supplies, site-wide CCTV security system, and the marina’s generous caravan and camping site.
