No more slipping for commuters at West Byfleet Station
– thanks to GLS 100R® Anti-slip coating

Business Situation

The problem – commuters on South West Trains routes were at risk of slipping in wet weather on the terrazzo-tiled surfaces on footbridges and platform areas.

The footbridge at West Byfleet Station, with its tiled surface, was one of the areas. So South West Trains turned to GLS Coatings Ltd for a unique solution: GLS 100R® anti-slip coating.

How was the work undertaken?

Andy Evans, Director of GLS Coatings Ltd., explains, "While we know that our GLS 100R® anti-slip coating provides the perfect solution to the problems which South West Trains were encountering, there was a really small window in which to carry out the work, as it had to be done during overnight possession."


Solution

GLS Coatings technicians have many years' experience in this specialist area applying a coatings system that is spray-applied, fast-curing and touch-dry in 5 - 10 seconds. This provides an unrivalled return to service time, which means the minimum disruption to production. Often, bunds are coated, sealed and back in operation the same day.

GLS Coatings Specialist Bund Coatings meet recent legislation, which states that bunds must now be in good repair, of adequate size and be completely watertight.


Benefits

Only GLS Specialist bund coating is resistant to a wide range of chemicals, from Potassium Hydroxide, to Hydrochloric and Sulphuric Acid.

GLS Coatings' chemical resistant bund coating structurally reinforces corroded structures and weakened substrates. Our coating adheres to concrete, brick, steel, vitrified and clay pipes, cast iron, asbestos, glass fibre and PVC.

GLS Coating is fast curing and is extremely durable and hard-wearing. It is ideal for bund refurbishments and has been approved for contact with potable water.


Footbridge at West Byfleet Station

Originally planned over three nights – the work was actually completed in just two, due to torrential rain making work impossible on the second night.


Night 1

The team of three Technicians arrived on site at West Byfleet Station at 21:30 on Tuesday, 15th September. The safety of passengers and staff is paramount, so barriers were erected at all access points.

The entire area was ground using specialist diamond grinders to remove the glaze from the top of the tiles. The area was then cleaned and all the dust was removed. It was noted there were signs of water oozing up between some of the grout lines. The technicians cut the wet grout out and introduced a PU sealant in its place to completely stop the water ingress.

Levels of moisture and dew point have to be closely monitored, when the temperature drops while working overnight. Recordings of moisture levels as high as 5%, with dew forming on the surface of the tiles, meant the team took the decision not to prime the area. And they finished work at 02:15.

After being rained off on NIGHT 2, Work began at 23:19 on NIGHT 3

The area was swept clean, before being chemically wiped to remove any residual grease. Next, a chemical Primer was applied to the tiles, to prepare the surface to receive GLS 100R®.

Finally, GLS 100R® Specialist anti-slip coating was spray-applied to the entire walkway. Because GLS 100R® is TOUCH-DRY in under 10 seconds, the team had completed the whole job, which was signed off by the Client at 03:18.

Later the same day, early morning commuters were streaming over the footbridge to catch their trains, completely unaware that less than 4 hours earlier, the bridge had received an entirely new, anti-slip coating.
