Requirement: Extensive Leaking through failed membrane system to residence below from podium level.

Requirement: A new facility was built for bulky retail goods, therefore it was mandatory to build three fire fighting water detention tanks. The shear size and water capacity meant that the waterproofing which was originally specified had cracked under the heavy load when the tanks were filled.

Requirement: Extensive leaking into several wards due to an old bitumen based asbestos membrane having perished on roof flats.

Requirement: Previously installed bitumen based waterproofing membrane was leaking at the overlaps and at outlets allowing water ingress, therefore damaging the concrete slab beneath causing concrete cancer and mould issues to the residential apartments below on the 8th floor.

Requirement:

The original membrain leaked.

Requirement:

Extensive water damage in all balcony
