The repair of concrete buildings and structures requires quality materials but more importantly experienced and skilled tradesmen to ensure that the repair is undertaken correctly. The removal of the defective areas of concrete, preparation of the exposed steel reinforcement, and concrete reinstatement has to be done correctly for the repair to be durable.
For small repair areas we use electric or pneumatic tools to remove the concrete and for larger volumes we often use hydro demolition. The concrete reinstatement can be hand applied mortars or for large volumes it may be sprayed gunite or flowable self-compacting concrete. The concrete surface finishing often needs to match the colour and texture of the parent which might be a shutter board finish or exposed aggregate finish. Our skilled workforce are able to achieve a high quality finish to match the parent concrete.
After repairing the concrete a protective coating can be applied to all the exposed concrete surfaces to enhance the durability and for aesthetic reasons. These coatings can protect against further carbonation of the concrete and chloride ingress.These services are undertaken by our own directly employed tradesmen they have the skills necessary to undertake the repairs. All our operatives have a training matrix covering a whole range of skill modules and attend regular training events with our material suppliers.
For slab extensions, wall extensions, and other general rebar doweling applications, chemical adhesive anchor systems provide a reliable solution for post-installed reinforcement applications. Chemical or resin anchors are generic terms relating to steel studs, bolts and anchorages which are bonded into a substrate, usually masonry and concrete, using a resin based adhesive system. Ideally suited for high load applications, in virtually all cases the resulting bond is stronger than the base material itself and as the system is based on chemical adhesion, no load stress is imparted to the base material as with expansion type anchors and are therefore ideal for close to edge fixing, reduced centre and group anchoring and use in concrete of unknown quality or low compressive strength
