Technical resources, decision guides, and reference materials for engineers, asset managers, and building owners working with structural investigation and non-destructive testing.
When to Investigate: A Decision Guide for Building Owners
Not every crack needs an engineer, but some signs should trigger a professional structural investigation. This guide covers the five key indicators: growing cracks, concrete spalling, water ingress, change of use, and building age beyond 30 years.
Read more →GPR Scanning: A Technical Overview for Engineers
Ground penetrating radar scanning uses electromagnetic pulses to image rebar, post-tension cables, voids, and utilities inside concrete. This overview covers how GPR works, when to use it, depth limitations, and how it compares to X-ray methods.
Read more →Concrete Scanning vs X-Ray: Technology Comparison
Both GPR and X-ray image what is inside concrete, but they use different physics, have different safety requirements, and suit different situations. This comparison covers access, safety, speed, detail, depth, and cost for each method.
Read more →NDT Technology Selection Guide
Choosing the right non-destructive testing method depends on your investigation objective. GPR for rebar mapping, UPV for concrete quality, thermography for moisture, half-cell for corrosion. This guide maps investigation questions to the optimal NDT technology.
Read more →Understanding Concrete Carbonation and Corrosion Risk
Carbonation reduces the alkalinity of concrete cover, removing the passive protection layer around reinforcement. This technical reference explains the mechanism, testing methods, and what carbonation depth results mean for your structure.
Read more →Post-Fire Structural Assessment: Retention or Replacement?
After a fire, structural assessment determines which concrete elements can be retained and which require demolition. UPV mapping, petrographic analysis, and visual classification guide the boundary between repair zones and replacement zones.
Read more →Structural Investigation Reporting: What to Expect
SiteOps investigation reports include executive summary, methodology, field observations, NDT results, lab data, risk classification per AS/NZS ISO 31000, and prioritised remediation recommendations. All reports are RPEQ-certified.
Read more →Australian Standards Reference for Structural Investigation
Complete reference of Australian and international standards governing structural investigation, concrete testing, NDT methods, and building assessment. Covers AS 3600, AS 1012 series, ASTM standards, and heritage regulations.
