The current site is a flat roof and is located in Kostinbrod, Sofia region.
Before applying the oiled waterproofing, the base had to be prepared.

As can be seen from the photos, the building is newly built and the roof has not yet been plastered after the installation of fiber.

We followed the following steps for roof waterproofing:

•     We plastered the boards and the base where necessary.
•     We processed all the corners on the boards, the chimney and the stand of the solar collector.
•     After leveling the base, we primed with Hydroflex-Grund waterproofing primer.
•     We applied Hydroflex-Universal liquid rubber.
•     As a rule, we also reinforced with a polyester veil.
