  • When do I need concrete crack injection?

    Concrete crack injections are commonly used to repair a range of issues to stop water leaks and permanently seal broken concrete surfaces. For waterproofing purposes, we use concrete crack injections for foundations, carparks, swimming pools, walls and water tanks. 

  • Which is better to use to repair concrete, epoxy or polyurethane?

     It depends on the type of concrete damage. Epoxy is ideal for smaller hairline cracks; however, polyurethane is suitable for bridging gaps and existing substrate. At Unique Waterproofing Solution, we offer both types of protective coating and will determine the most appropriate course of action.
