Background Of The Project

Allard Construction Ltd worked on behalf of EA Group who were acting as a direct consultant for the commercial building 40 Whitfield Street. The tenants of the building were experiencing leaks meaning repairs needed to be carried out as soon as possible. After we resolved the leak issues EA Group then requested for Allard Construction to complete extra works where we applied a Sika Liquid Plastics Decothane Ultra overcoat system to the entire roof area.

Description Of Works Carried Out

Allard Construction Ltd installed a scaffold tower and hoist on the front of the building for access so that the tenants were not disturbed. The previous roof coverings were replaced with a brand new 20 year warranted system and Sika Decothane Ultra overcoat was applied to the entire roof area. The handrail on the roof was raised, coated and then reinstated. Due to the handrail being inside the parapet walls the upstands were completed using a mobile harness anchoring system and specialist rescue procedures.

Challenges Faced

The works had to be carried out in a live operating office therefore Allard Construction Ltd ensured that noise pollution was kept to a minimum and that safety signs were clearly displayed.


Allard Construction Ltd arranged for the majority of works to be carried out on the weekends so that the tenants were not disturbed. The scaffold and hoist were installed and removed during the weekend including the installation of the termination bar. Allard Construction Ltd decided to use Sika Liquid Plastic’s Decothane Ultra for the waterproofing works instead of a standard Decothane as it is virtually odourless meaning that no high solvent smells were distributed to the offices below.
