Recently a customer from Puerto Rico approached us about repairing a driveway and sidewalks badly cracked by continual earthquakes. We told the customer we were not sure any product was made to withstand continual earthquakes but he decided to give SANI-TRED a try.
On the driveway the customer applied one coat of PERMAFLEX then addressed the cracks with our LIQUID RUBBER BASE (LRB). He then applied a second coat of PERMAFLEX and broadcast polymer flakes into the wet PERMAFLEX for a more decorative look. The customer then applied two coats of our SANI-TRED SUPERTHANE polyurea clear topcoat.
On the sidewalks, the customer applied one coat of PERMAFLEX then addressed the cracks with our LIQUID RUBBER BASE (LRB). He then applied a second coat of PERMAFLEX as a topcoat.
Here is what the customer had to say about the solution:
“A recent 4.9 earthquake did not seem to have opened up the cracks that were filled with LRB. Hairline cracks that were just double-coated with Permaflex are visual but have not failed. The topcoat of polyurea that was double-coated is somehow still holding, and the floor has held its full integrity. If the topcoat begins to crack, we will just sand it and reapply more polyurea.”
