The service station OCW Oberscheider Car World GmbH in Lustenau is one of the busiest filling stations in the area.The area around the fuel pumps is subject to very heavy wear. Consequently special criteria apply when it comes to usage requirements for the outer layers.
The requirements stipulated a forecourt surface that was safe underfoot and to drive on in any weather conditions. The surfacing had to be resistant to fuels, UV light, abrasive wear and large differences in temperature. At the same time the client wanted a surface that was easy to clean and keep clean. A welcoming colour concept rounded off the list of requirements.
The desired, safe and non-slip solution was found in conjunction with waterproofing specialists Rhenus Handels GmbH from Hohenems and WestWood Kunststofftechnik:
The fuel-contaminated asphalt concrete areas around the pumps were removed down to the sound foundations and the rubble taken away. The surface was then given the best possible pre-treatment in the form of fine scarification and shot blasting. Afterwards the entire area was coated with the PMMA-based primer Wecryl 298. Any larger areas of damage were made good with Wecryl 242 reprofiling mortar. This was followed by an elasticised protective layer of Wecryl 233 with an extremely hard-wearing silicon carbide topping.
The final layer consisted of Wethan 484, a special, fast-curing sealer with high chemical resistance. Thanks to the rapidly setting system build-up it was possible to renew a complete forecourt lane, including waterproofing of gullies and details, primer, protective and wearing layer, in a single day. Since only sections of the forecourt were closed off, the service station could continue to operate almost unhindered.
