Commercial Waterproofing & Remedial Services — Perth, WA
WE FIND IT,
WE FIX IT.
Ingrex Group delivers leak detection, waterproofing and structural remediation for strata managers, building managers and commercial builders across Perth — backed by standards-compliant work and detailed reporting.
What We Do
SERVICES
Eight core disciplines, one focus: stopping water ingress and restoring the structures it damages.
Leak Detection
Non-destructive moisture tracing and source isolation for roofs, balconies, basements and building envelopes — before damage spreads.
Waterproofing
Membrane and injection waterproofing systems for podiums, balconies, wet areas and below-grade structures.
AS 3740:2021 / AS 4654.1 & 4654.2:2012
High-Pressure Injection
Polyurethane and epoxy resin injection under high pressure — sealing active cracks and leaks in concrete and masonry without breaking out the structure.
Concrete & Structural Remediation
Spalling repair, crack injection and structural concrete restoration for ageing and water-damaged buildings.
AS/NZS 4858:2004
Silicone & Joint Sealing
Expansion joints, control joints and perimeter sealant — replaced and resealed to manufacturer specification so movement doesn't reopen the leak path.
Façade & External Repairs
Render, coating and sealant repairs to building exteriors, addressing water ingress at its source.
Strata Maintenance Programs
Scheduled inspection and maintenance programs built for strata managers, building managers, and commercial builders — planned work, not reactive call-outs.
Emergency Response
Rapid response assessment and make-safe works for active leaks and water damage events.
Why Ingrex
BUILT FOR COMMERCIAL
STANDARDS
Strata managers, building managers, and commercial builders need work they can put their name on. Here's what that looks like.
Backed by 20 years of hands-on experience in WA construction and remedial work — across mine sites, government sites, main roads, commercial, industrial and residential projects.
Our team has delivered work for some of WA's largest builders, including Multiplex, Pact, SKS, Pindan, ABN Group, Doric, BGC, Jackson, John Holland and more — with deep experience across aged care, schools, hospitals, shopping centres and stratas.
Licensed & Insured WA
Operating under Western Australian licensing and insurance requirements for commercial remedial work.
Standards-Compliant Work
Every job referenced against the relevant Australian Standard and NCC clause — not guesswork.
Detailed Reporting
A full final report at project sign-off, plus a warranty certificate where the work is covered — both filed for strata records and building files.
Built for Commercial Work
We work with strata managers, building managers, and commercial builders who hold us to professional standards.
Latest Detection Equipment
We use the latest moisture-tracing and leak-detection equipment on the market, for faster and more accurate diagnosis before any work begins.
About Ingrex
A DEDICATED
COMMERCIAL
DIVISION
Ingrex Group was established to give Perth's strata managers, building managers and commercial builders a remedial partner that works to the same standards they're held to — professional, standards-compliant work on every job.
Every inspection is referenced against the relevant Australian Standard, every job is documented, and every report is written for the building file — so the paper trail holds up as well as the repair does.
For work outside our core trade, we coordinate a vetted network of plumbers, painters, rope access technicians, tilers and building inspectors — so strata managers, building managers and commercial builders get one point of contact for the full scope, not five separate trades to manage.
Licence & ABN available on request — registration in progress as we set up Ingrex Group's commercial entity.
