For some large commercial buildings, the car park is situated above an occupied premises such as an office, reception area or retail space.
This poses a few structural challenges and developers often consider it prudent to over-engineer the solution to make sure that no water, chemicals or other liquids will leak through from the overhead car park.
This is achieved by installing a crack-bridging deck coating solution in the car park level that has been reinforced with a fleece.
Incorporating a fleece within the floor enhances it with a cohesive and tear strength that is higher than the bond strength to the primed substrate so that in the event of any excessive movement, the system is able to spread the stress and accommodate it across the widest area. This method provides the utmost in protection, stopping any liquid penetration to the deck or occupied premises below.
