At Flash Concrete we provide a large range of services that involve works inside and out. Having been involved in over 3000 repairs to earthquake damaged homes and exteriors, we have come across just about all possible scenarios, and have developed numerous key techniques to either repairing or replacement items, whilst keeping a close eye on the client’s budget.

We have also been involved in many civil and commercial projects around town.
