Alchimica products provide perfect solution

A range of Alchimica products have been used to provide a waterproofing solution for a warehouse roof in Aberdeen. The waterproofing was failing rapidly and the roof was in a terrible condition. There was so much water under the felt in places that it was like walking on a large waterbed.

The hardest part of the job was clearing the area. Because of the terrible condition of the roof there was a lot of rubbish and useless material to remove. Once this was done, however, Alchimica’s products were used extensively.

The process was to:
• Fabricate and fit new roof penetrations for A/C pipework etc. and seal with Alchimica Hyperseal 50FC
• Prime roof surface with Alchimica Microsealer 50
• Coat roof surface with Alchimica Hyperdesmo PB2k
• Apply adhesive and fix down Rockwool recovery boards
• Apply self-adhesive fleece joint tape to all board joints
• Create a filet with Alchimica Hyperseal 50FC to all joints between the recovery boards and the perimeter wall, roof penetrations, condenser frames and upstands etc.
• Apply Alchimica Geodesmo 50 Primer to complete surface and allow to cure
• Apply Alchimica Hyperdesmo HAA in two coats for a total coverage of 2kg p/m²
• Apply Alchimica Hyperdesmo ADY-E, 1m x 100m fleece rolls, kiln dried sand and a top coat of ADY-E (grey) to create a strong nonslip pathway between the roof access and condenser locations.

After years of problems with leaks and never being able to sort the problem properly Alchimica’s products offered the perfect solution.
