The original carpark surface was leaking and in poor condition and the client was looking for a robust system that would both be waterproof and could handle car traffic. The product had to be durable, strong and flexible enough to handle minimal movement that occurs in today’s modern structures.


To remove the existing membrane and hotmix and replace with a new mastic Asphalt waterproofing layer topped with a mastic asphalt paving grade trafficable system.  Asphaltech had engaged Surfprep a local company to work night shift to remove the existing surface and Asphaltech would come in early in the morning and waterproof the stripped area. Once the area was stripped and waterproofed completely Asphaltech would then return and complete the Mastic asphalt paving layerpaving layer. \once again Asphaltech had completed a successful remediation.
