Slab Flooring Case Studies

Machine Shop Floor

machine_sfloor The area in question had existing tooling machines removed prior to the installation of new tooling for a new project & the client required the slab to be renovated to meet Company standards in relation to Health & Safety, cleaning requirements and the working environment for its employees. The concrete slab that was to be prepared, repaired & coated dates back 80 years & at various times in the past repairs have been carried out which meant there were a number of different substrates in the area. The preparation was by means of a blast & a mechanical grind to remove the surface fully. The repairs were carried out using an epoxy resin repair system. The area around the trench posed a number of problems as there was a metal runner set into the base which had to be sealed before the repair could be carried out. There were also 2 areas where there were differences in the floor level. This was solved by hand grinding the heights before using a self- levelling epoxy resin. The slab was then primed using a water based primer to seal the slab and to provide a surface that would produce the optimum conditions for the coating system to bond to. The first coat of High Build Epoxy Resin in light grey, with slip resistance added to meet the client’s health & safety requirements, was applied. This then received a final coat of the High Build Epoxy Resin with added slip resistance to ensure that the client’s remit had been met.

Vehicle Repair Shop Floor

vehicler_sfloorThis project to prepare & apply the coating system to the garage slab had to be carried out over a single weekend with no loss of operations time for the client. The zones that they required around various ramps, work areas & the MOT bay would be created on the following weekend. At the planning stage it was agreed with the client & the mechanics who work in the garage that we could start preparation works on the Friday. This meant co-ordinating tasks to work with and around the mechanics to ensure the preparation & priming was completed that day with the minimum of disruption to them. Being a operational vehicle repair shop meant that the existing floor was very dirty with oil & grease stains. The first task was to clean the floor before the mechanical grind took place. This was achieved by dividing the floor into separate areas. Each area was cleaned using a floor scrubber with degreasing agents added. The more stubborn stains were cleaned by hand scrubbing. The area was then rinsed and dried off so that the preparation could begin. This process was repeated until the full floor had been treated. The preparation was by means of a grind using diamond grinders to take of the surface layer. Areas that needed to be repaired were cut back were required using angle grinders then tack primed & filled with a fast curing epoxy mortar system. After the curing period an oil tolerant primer was applied due to areas of impregnation of the slab. On the Saturday the first coat of High Build Epoxy Resin, with slip resistance added to meet the client’s health & safety requirements, was applied. On the Sunday a top coat of twin pack Polyurethane Epoxy Resin was applied as this would provide an ultra violet stable finish with excellent cleaning properties. The following weekend we returned to implement the required working zones by applying lines & boxes. The relevant areas were cleaned by hand using the same degreasing agent as previously used. This were then measured & marked out and prepared by hand to give a good key. The areas where then coated using epoxy resin line marking paint in white, yellow and red as specified. Slip resistance was added to this to ensure that there was a consistency of grip across the whole area.
