At AWS we provide a wide range of concrete repair services throughout Sydney, Perth and Melbourne including structural repair & strengthening.
When fixing concrete cancer or cracks due to movement, you must take into account why the problem has occurred and the fact that the problem must be fixed prior to the concrete being fixed. We specialise in the repair of concrete by identifying the cause first, solving that and then fixing the concrete structure.
Many buildings, structures, roads and storage tanks are made of concrete, which consist of aggregates such as sand, gravel or crushed stone, water and cement. Water and cement merge to form a paste which binds together the aggregates into a rock-like mass.
Concrete Cancer (otherwise known as concrete spalling) is caused when the steel reinforcing within a concrete slab begins to rust. As steel rusts it can expand up to 7 times its original size causing the surrounding concrete to be displaced and flaky. As the steel pushes the concrete away, more water gets to the steel expediting the process.
AWS can repair the steel within the concrete and then repair the concrete itself. Each situation is unique and requires different solutions. Once we are on site we will advise you on which system you should undertake in order to rectify your situation properly.
Where the issue has originated in the slab on the roof of the building structure, in most cases it is likely that waterproofing will need to be undertaken. Once the rusted reinforcing has been treated, application of a waterproofing membrane will help prevent access of moisture to the slab and prolong the life of the steel and therefore the structure itself.
