Concrete Repairs

Owners of 22-24 the Avenue, Crawley

Before: evidence of concrete cancer

Description

The Owners of 22-24 The Avenue, a 3-storey apartment complex located in Crawley, engaged BUSS to assess the indications of concrete cancer, and its source, to the balconies of each of the 3 levels of the structure. BUSS discovered that the planter boxes, which channel along the perimeter of the balconies, and the balustrade bases had not been properly waterproofed/sealed therefore allowing water to penetrate through to the concrete. Of course, when water and oxygen penetrate concrete, the steel reinforcement bars corrode and expand causing concrete cancer.

Tasked with the concrete repairs to the affected areas and the waterproofing of the balconies, BUSS utilised a 3-storey scaffolding system which allowed easy access to the work faces.

BUSS delineated the repair areas, broke out the loose concrete and treated the rust on the reinforcement bars. A form and pour method of repair was used for the larger repairs to both sides of the balconies (pourable repair mortar Renderoc LA55), while the smaller repairs were completed by hand using a patch repair method (Renderoc HB40).
