Technical Specifications & Design Support

Projex Group provides professional technical guidance to support the correct specification of Cosmofin PVC waterproofing membranes.

With more than 35 years of experience in the Australian waterproofing industry, our team assists architects, engineers, consultants and builders in selecting practical and compliant waterproofing solutions suited to their project requirements.

Our role is to help ensure the selected system performs as intended while meeting relevant design, durability and compliance expectations.

Technical Guidance for Project Design

Our team can assist project stakeholders with:

  • Preparation of project-specific waterproofing specifications
  • Development of system build-ups and detailing concepts
  • Review of drawings and proposed waterproofing assemblies
  • Guidance regarding compliance with relevant Australian Standards
  • Advice on difficult detailing or unusual site conditions

Whether the project involves podium decks, basements, balconies or other exposed structural elements, we help ensure the nominated Cosmofin membrane system is appropriate for the intended application.

Project Specification Documentation

To support the design and tender process, we can prepare technical documentation that:

  • Defines the required waterproofing system and scope
  • Identifies key installation requirements and detailing considerations
  • Provides guidance on installation quality expectations
  • Clarifies the applicable material warranty provisions
  • Helps reduce uncertainty during tender and construction phases

Cosmofin membranes are supplied with a manufacturer material warranty.

If required, Projex Group can also provide site inspections or installation reviews upon request.

Our objective is to assist consultants and engineers in preparing reliable waterproofing documentation that supports both design intent and long-term building performance.

Early Design Collaboration

We often become involved during the early design stages to help:

  • Identify potential waterproofing risks
  • Resolve challenging details before construction begins
  • Assist the transition from design documentation to site installation

Working with Projex Group gives project teams access to practical waterproofing knowledge, combining product expertise with real-world installation experience.

If you require assistance specifying a Cosmofin waterproofing system for an upcoming project, our technical team will be happy to help.
