Water ingress and waterproofing across Sydney & the Southern Highlands
Grand Oak Building investigates water ingress and completes waterproofing and related remedial work across the Southern Highlands and Sydney’s inner west, west, south-west and southern areas. Our ARDEX-accredited capability supports wet-area and building-envelope repair scopes where water entry, failed waterproofing or associated deterioration needs to be addressed.
Identify the water issue before deciding on the repair
Visible moisture does not always show where water is entering the building. The repair scope needs to consider the affected area, likely pathways and the condition of existing waterproofing or building elements before suitable remedial work can be planned.
