Refurbishment without demolition of car park roofs: double-layer semi-adherent system under asphalt floor

Also when renovating car park roofs, when the level of the protrusions and access thresholds permit, it is always advisable to avoid demolition work and the cost of waste disposal by laying a new waterproof membrane, consisting of flame-bonded distilled bitumen polymer membranes, directly on the old flooring in asphalt or concrete. If laying on old concrete flooring, it is preferable to choose to lay the membrane in partial adhesion to avoid the formation of bubbles that might develop before the new floor has been laid, because of damp trapped in the foundation, while if laying on old asphalt that is sufficiently porous, the membrane can be laid in full adhesion, and this type of bonding will always be used if renovating parking access ramps
