New construction to Audi dealership to provide rooftop parking above service bay.
BDB Design & Build
Systems used TREMCO MMA Rapid Cure Flexible System Migutan FP90 Joints
30 lm joints
Construction was composite metal decking/concrete followed by insulation and a reinforced concrete topping above. The trafficable waterproofing system was installed on top of this.
Joints were required to accommodate major movement between existing and new construction.
Installation took place in early spring with marginal weather conditions, so the low-temperature and rapid-cure features that characterise MMA waterproofing systems were essential.
The joints were sealed with Migutan FP90 mechanical movement joints that were integrated with the waterproofing system to provide a guaranteed, single-point solution. TREMCO has been the UK & Ireland agents for the European market-leading Migua Jointing Systems for over 35 years.
TREMCO was selected on a combination of track-record, performance and cost-effectiveness.
The TREMCO Technical Services team were on-hand at all stages of the project and were able to advise on an MMA resin screed to correct falls to drainage.
Polyurethane (PU) products are known to be versatile, innovative and safe – whilst they are used in a variety of applications in construction, packaging, automotive industry and many more – these products are made by reacting diisocyanates and polyols.
The existing failed waterproofing system was removed by planing and vacuum blasting of the concrete to remove surface contamination.
