Bellingham Station

Bellingham Station opened in 1892 and is located in South London. It forms part of the ‘Catford Loop’ which is an estimated 8 miles long and also includes Crofton Park, Catford, Beckenham and Ravensbourne stations.

Survey: A Suitable Specification

Bellingham Station was exposed to an expired zinc roofing system, causing damage to the structural timber deck and in turn, decoration work to the underside canopy. The track-side guttering system had actually become dangerous, with parts of the gutter falling onto the track in severe weather conditions. The Stations main building tiled roof had also expired, requiring renewal to protect the newly renovated accommodations.

On our survey, it was noted that the existing system had failed to protect the canopy makeup and this led to further remedial work needed. Works included the complete removal of the existing structural deck coating and the installation of an additional Plywood Deck, to strengthen the canopy while providing a hard edge for the adhesion of the roofing system. The Stations main building roof also required suitable matching against the existing tiles, which were simply not manufactured anymore.

Yalding Station

Yalding Railway Station is on the Medway Valley Line in Kent and operated by Southeastern Rail. The APTIS-equipped ticket office (on the southbound platform) closed in 1989 as the building was then used for commercial purposes. G S Moore were proud to be awarded the refurbishment works, applying careful management and planning throughout.

Survey: Safety First 

Yalding Station needed full refurbishment after being unmanned for quite some time. Severe damage from weathering, neglected faults and a ‘life expired’ waterproofing system all contributed to degradation, water ingress and timber rot of both the station canopy and entrance roof.

Our survey noted that, the main beam intersections underneath the guttering had rotted away due water ingress. We specified with the client, replacement of the timber supporting structure and box guttering due to severe degradation over many years of neglect. GSM Access also installed a man-safe system, enabling safe maintenance access to the new Flex-R EPDM RubberBond FleeceBack Gutter System.

Sandwich Station

Sandwich, a Southeastern Railway Station, opened as a single line track 1 July 1847. It later added a connection to Dover Priory June 1881 and in 2019, major works began to expand the station, in preparation for The 2019 Golf Open Championship. Platforms were extended to 80 metres to accommodate larger trains. Works continue into 2020 in readiness for the 147^th Open Championship.

Survey: The importance of a survey

The Station building pitched roof, waiting shelter and platform canopies at Sandwich were all in extremely porous states. Our survey noted severe rain ingress from the loft areas, expiration of existing, man-made fibre slate and severe defects to the chimney stacks, all contributing to the cause. The Platform canopy was single skin aluminium sheeted, with drainage and timber valances that were all in need of replacement.

On our survey, our surveyors found severe water ingress, rotting timber frames and collapsed valley guttering. The chimneys were missing masonry work and the parapets, saddles and cornices had all expired, causing brickwork to collapse. The waiting shelter water proofing had also expired and previously suffered fire damage.

Margate Station

Margate Station opened 1 December 1846 and was later rebuilt in 1926. Our survey noted Margate Station  was Grade II listed in 1987. The main building is constructed in a classical style, including brown brick, stone dressing and a hipped tiled roof. The booking hall is built similarly, but in a distinctive ellipse shape with pendant lighting.

Survey: The right Solution

Areas of Margate Station were extremely degraded, with severe water ingress throughout the box gutter and glazing systems. The existing fibre roof slate had expired and the existing Georgian wire glazing either broken, slipped or simply missing over the years, due to wear and tear, gull nesting and ‘life expired’ waterproofing.

We wanted to improve upon the existing specification, offer better longevity and include PPM within the scope of works.
Working with the client, we agreed to specify Plasiax GWP, a sheet plastic more superior and 25 times stronger than glass. It’s virtually unbreakable, lightweight and weather resistant, with a 50-year warranty and little to no maintenance. We combined this with a laser etched, wire print and a stipple effect finish to create an exact atheistic match to the original Georgian wire glazing.

Tunbridge Wells Station

Tunbridge Wells Station opened by SER 25th November 1846 servicing both London Charing Cross and Hastings, as well as shuttles to Tonbridge and London Bridge via Redhill.

The Clock Tower, Tunbridge Wells Station

Tunbridge Wells Station is a Grade II listed building. Team GSM’s specialist carpenters installed new Green Oak timber beams to the suspended canopy system. The specialist glazing team then installed a Plasiax Georgian wire polycarbonate system with PPC self support glazing bars, followed by a full paint refurbishment using a Jotun Demidekk Microporous System.

Tunbridge Wells Station was suffering from severe rain ingress through the internal loft area, drainage blocked (unrepairable) and the lower roof had suffered vandalism, theft and graffiti. Its Clock tower had no safe means of maintenance access and externally, it had severe timber rot, delaminated lead and corrosion to all 4 faces as well as heavy rain ingress and an expired weather vane with no lightening conductor.

Herne Bay Station

Serving the town of Herne Bay and staring in Some Mothers Do ‘Ave ‘Em, this station was originally constructed by the Herne Bay and Faversham Railway Company, opening in 1861 as “Herne Bay and Hampton-on-Sea”.

Survey: Specialist Materials

Found on older buildings, the existing valley gutters were failing, allowing heavy rainwater to collect, stagnate and ingress on the flat roof. The timber cross section was also bowing, rotted and had been temporarily propped up, spoiling the atriums. Finally, the drainage system was completely blocked.

G S Moore Roofing always try to source materials locally however, green oak timbers were required for Herne Bay, which at the time (2019) – had to be imported from France. Our Contracts Manager, Rob Allan worked tirelessly with the French suppliers, arranging the import to Tilbury Docks, transportation to site and fitted, all within 24 hours. Thanks also to Swains who we sub-contracted the lifting to. A great team effort all round and a fantastic achievement for Team GSM.
