Mapei tiling at Darlington Station: slip, durability and VOC notes for designers

30 Second Briefing
Mapei’s tiling system has been installed over more than 3,000 sq m at Darlington Station by The Tiling Company (Northern) for BAM UK & Ireland, as part of the £140m upgrade that includes two new platforms linked by a 50-tonne footbridge. The build-up used Mapeproof One Coat epoxy DPM, Eco Prim Grip Plus, Ultraplan Renovation Screed 3240 and Mapetex anti-fracture, with tiles fixed using Keralastic, Keraquick Easy S1, Keraquick XL Fibrelite and Keraflex Maxi S1, then grouted with Ultracolor Plus. R11/R12 slip-rated surfaces and EMICODE EC1 Plus low-VOC, CO2e-offset products address heavy footfall, moisture and indoor air quality demands.
Technical Brief
- Mapeproof One Coat epoxy DPM was applied to control residual slab moisture before tiling.
- Eco Prim Grip Plus primer was used to enhance bond between existing substrates and subsequent levelling screed.
- Fibre-reinforced Ultraplan Renovation Screed 3240 provided self-levelling and load-distribution over irregular base slabs.
- Mapetex anti-fracture membrane was installed to decouple tiles from substrate shrinkage and movement-induced cracking.
- Four distinct adhesives (Keralastic, Keraquick Easy S1, Keraquick XL Fibrelite, Keraflex Maxi S1) were selected by location and loading.
- Ultracolor Plus grout was specified for joints to balance abrasion resistance, colour stability and rapid return-to-service.
- Post-handover, Mapei UltraCare produced a detailed cleaning regime to preserve slip resistance and surface texture.
- Cleaning specification differentiated pH-neutral UltraCare Multicleaner for daily use from UltraCare HD Cleaner for periodic deep cleans.
Our Take
The £140m Darlington station upgrade already features in our database via delivery coverage on BAM UK & Ireland and Network Rail, so this Mapei-focused piece effectively fills in the fit-out and materials side of the same East Coast Main Line scheme.
R11–R12 slip-rated tiling at a high‑footfall UK rail hub signals that future Network Rail and LNER concourse refurbishments are likely to benchmark against similar anti‑slip and durability specs, particularly where step‑free access and new footbridges concentrate pedestrian flows.
Within our 910‑item Infrastructure set, relatively few Product‑tagged UK station projects drill down to specific systems like screeds, primers and cleaners, so this gives contractors a rare reference point for a complete tiling build‑up that has already been accepted on a Grade II‑listed mainline station.
