Access ramps and delivery area of the administration building of the VHV Group.
The access ramps and the VHV Group administration building delivery area in Hanover were in need of refurbishment. Cracks and mechanical wear in the existing surface coating had led to leakage in the underground car park. In order to protect it from moisture in the future, the refurbishment called for a highly resistant, waterproofing system suitable for vehicle traffic that would permanently withstand the loads of the vehicles entering and leaving. In addition, refurbishment could only be carried out over the weekend to avoid
interfering with employee parking. Dipl. Ing. Gerd Adamek from LPI Ingenieurgesellschaft mbH was seeking the best economical and technical solution on behalf of his client, the VHV Group. Working with the Triflex contact partners Harm Stelling and Sebastian Lücke, the decision was made to use the top deck waterproofing system Triflex ProPark with a polymethyl methacrylate (PMMA) resin base.
Refurbishment requirements
