Waterproofing Services

We deliver professional waterproofing solutions across Sydney for residential, strata and large-scale construction projects.

 

Our work ranges from targeted remedial treatments in private homes to full membrane systems on multi-level developments. We focus on correct diagnosis, proper preparation and durable systems that perform long term.

 

Residential Waterproofing

 

We assist homeowners with:

  • Rising damp treatment

  • Basement waterproofing

  • Balcony and roof membranes

  • Retaining walls and planter boxes

  • Negative and positive side waterproofing applications

 

Every project starts with understanding the source of water ingress. We apply the right system for the structure — not a temporary patch.

 

 

 

Strata & Property Management

 

 

We provide waterproofing solutions for apartment buildings and strata-managed properties, including:

 

  • Common area membranes

  • Planter box failures

  • Basement seepage

  • Balcony remediation

  • Concrete crack sealing

 

We understand access coordination, compliance requirements and the importance of clear communication with building managers and owners.

 

 

 

Construction & Commercial Projects

 

 

We act as a specialised waterproofing applicator on large construction projects, working alongside builders and major waterproofing suppliers.

 

Our team is experienced in applying advanced membrane systems and crystalline waterproofing technologies for:

 

  • Basements and lift pits

  • Suspended slabs

  • Retaining structures

  • Concrete water tanks and structural elements

 

We bring the manpower, equipment and technical understanding required to execute these systems correctly and efficiently.
