Technical Advice


Pre Construction


  • The building design is assessed to review effectiveness of first principles such as: water shedding of horizontal elements, effectiveness of flashing and cavity systems, potential for differential movement in waterproofing elements.

  • Recommendations of most appropriate waterproofing detailing and membrane solutions.

  • Facilitated workshops are conducted to co-ordinate the inputs of the various stakeholders.




  • Determination of cause of water entry.

  • Consideration of strategic and technical options.

  • Selection of optimum materials and systems.

  • Drafting of technical and contract documents.

  • Selection of contractor.

  • Quality assurance inspections and drafting of maintenance plans.

  • Analysis and repair of consequential damage to concrete stone and finishes.

Design Peer Review 


Rather than spending time on repairing defects after they occur, there is great benefit in undertaking a peer review of contract documents, including architectural and engineering drawings.


Prior to commencement, we interrogate the details to ascertain which elements are likely to lead to water penetration, with particular attention to:


  • Roof, podium and balcony details

  • Junctions of windows and doors with adjacent façade elements

  • Review of curtain wall and window wall detailing

  • Basement and retaining wall protection.


Our philosophy is to encourage integrated water shedding, which considers the interaction of:


  • Hydraulic design, with particular regard to drainage from roofs, podiums and balconies

  • Architectural and engineering design of concrete profiles

  • Waterproofing membrane, sealant selection and detailing


This is achieved by facilitating interdisciplinary design detailing workshops.

Defect Analysis 


Building water penetration problems are complex and pervasive. A rigorous process is used for determining the optimum method of rectification.


  • Determine the cause of water entry through deconstruction of a typical detail (non-destructive analysis used where appropriate)

  • If required, ascertain legal responsibility for the defect

  • Survey complete building to quantify different mode of ingress, their frequency and location

  • Determine appropriate method of rectification

  • Test assumptions through construction of prototype repairs

  • Compile scope of works and / or specification for execution of the necessary works

Collaborative Defect Resolution 


Often in the building industry large expenditure and effort is devoted to litigation of waterproofing issues. As an alternative we encourage a collaborative approach to defect resolution.


We facilitate the following process in collaboration with all parties:


  • Analyse defects to establish source and cause.

  • Survey entire building to determine extent and location.

  • Review contract history to define responsibility.

  • Sketch proposed repair details, defining material selection and repair methodology.

  • Oversee formation of Deeds of Release with appropriate legal input.

  • Advise in appointment of independent Project Manager for supervision of works.
