Our approach is to identify the likely source and pathway of water ingress, assess the affected area and select a repair or waterproofing method suited to the condition of the building.

• Poorly sealed penetrations
• Groundwater and hydrostatic pressure
• Damaged concrete
• Drainage problems
• Water pooling
• Deteriorated balconies or external areas
• Failed previous repairs
• Building movement or settlement
• Defects around pipes and other services

Finding the source is important because simply sealing the area where water appears may not resolve the underlying pathway.

Signs you may need leak repair and waterproofing

Water ingress is not always immediately obvious. Some problems develop gradually and become noticeable through changes to the surrounding surface.

Signs include:

• Damp patches on walls or ceilings
• Active dripping or water flow
• Water pooling after rain
• Persistent moisture
• Efflorescence or white salt deposits
• Staining on concrete
• Peeling paint or coatings
• Mould or musty smells
• Cracking around affected areas
• Rust staining
• Concrete spalling
• Deteriorating joints or sealants
• Recurring leaks after previous repairs

If a leak keeps returning after surface sealing or patching, the underlying water pathway may need further investigation.

• Whether the leak is active
• Whether concrete cracking is involved
• The condition of existing waterproofing
• Whether joints or penetrations are contributing
• Whether previous repairs have failed
• Which repair method is suitable

Can leak repair and waterproofing be carried out from inside?

In some situations, yes. Certain concrete cracks, joints and water ingress pathways can be treated from the accessible side using injection or other internal waterproofing methods.

However, this isn’t suitable for every leak. The construction of the building, location of the defect, water pressure, existing waterproofing and condition of the substrate all need to be considered.
