The Challenge & Scope of Works
The podium deck was situated outside high profile local shops in the heart of London's trendy Fulham, so traffic management was key to keeping these business's fully functional during the disruptive works but also managing a safe place for the general public and shop owners to go about their every day business safely. The shops had basement areas directly below the public footpath used as sales areas and store rooms, we were informed a number of solutions were attempted over the years but none of which solved the problem.
Phase Two - Prokol Polymers Primer System
Prokol Polymers Technical Inspectors reviewed the prepared concrete deck and specified a water based primer Prokol Profast Primer R - solvent free fast curing application with integral fillers based on Pure Polyurea combinations, suitable for moist mineral surfaces and is shrink proof. This application also applied to all elevated public walkways where the water ingress passing through the concrete was causing stalactite build up and progressive structural damage. Kiln dried sand was broadcast into the primer system and covered the area whilst the primer cured (primer cure time 30 to 40 minutes) this allows for full traffic ability and turns a chemical key to mechanical key without the need to re-apply primer in poor weather conditions. Most importantly though the primed substrate is anti - slip at all times plus fully waterproof.
Prokol Polymers CE Certified Hydrophobic Pure Polyurea Liquid Coating withSystem 8 Second Cure
Once the primer has cured Prokol Polymers CE Certified Hydrophobic Pure Polyurea Seamless Membrane System can be applied, The Rocathaan 136T liquid membrane cures in 8 seconds and has 330% elongation for thermal movement and thermal shock, any expansion joints under 10 mm were directly over coated once serviced, any joint over 10 mm received a de-bonding strip mechanism and this was then also directly over coated.
The Finish is a Monolithic -Wear Restant - Chemically Resistant & Fully Hydrophobic Coating at 3 mm DFT (Dry Film Thickness)
