We are seeing a substantial increase in queries relating to leaking carparks - specifically, where suspended concrete slabs are leaking into the carpark below. In the experience we have gained over 50 years in dealing with these issues we have found a majority are due to defects and faults in the installation or specification of the waterproof membrane over the structural slab. Unfortunately it is not just old buildings, but is being seen in buildings constructed in the last 5-6 years.
What can be done
Building and structural reports are a great first step. However they are often too 'high level' to use for quoting purposes; they do not include aspects vital to the owners being provided 'apples for apples' quotes based on detailed assessment of their particular issues.
Through detailed assessment of the particular issues being experienced on a property Conspar provides owners with a certified remediation strategy that includes a detailed scope of work, materials specifications, construction details and project budgets with warranties of up to 20 years.
