Forensic Hydraulic & Plumbing Advisory
Brisbane, Queensland

Independent technical evaluation of hydraulic systems within the built environment.

Gemark Consultancy provides structured forensic assessment of plumbing, drainage and stormwater systems in matters involving water ingress, system failure and disputed hydraulic events.

Engagements are undertaken independently of repair or rectification contracting and are limited to technical evaluation within defined scope.

Practice Overview

The forensic advisory division of Gemark Consultancy focuses on hydraulic system behaviour rather than general inspection reporting.

The practice provides independent causation analysis where water movement, drainage performance or plumbing configuration is in question.

Instructions may arise from property owners, insurers, legal representatives or building professionals requiring technical clarification of system behaviour.

All findings are confined strictly to scope and observable evidence.

Technical analysis considers relevant provisions of the National Construction Code (NCC) and applicable Australian Standards where appropriate.
