Foundations and slabs

Soil movement, drainage and footing problems that affect houses across South East Queensland.

Retaining walls, slopes and storms

Ostanes were great right from the outset - they responded very promptly even on the weekend and we had the inspection and structural engineering report within two days of first contacting them. The admin staff and engineer were both very friendly, helpful and communicative - we'd be happy to use them again. Thank you!

Ostanes have been fantastic to deal with from start to finish. Prompt turnaround times, great correspondence and advice. A small project for a Home Builder for a bathroom extension was made easy by their engineering know how and support every step of the way. Would highly recommend. Thanks to the whole team!
Response from the owner:Thank you, Adrian! We’re glad we could support your project with clear advice and quick turnaround. We appreciate the recommendation and look forward to helping again anytime! 𝐎𝐬𝐭𝐚𝐧𝐞𝐬 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠

We had a underpinning company quote us $10,000+ to fix an issue with our house foundation. I wanted to get a 2nd opinion and that of a structural engineer because i didn't want to pay for something i didn't need. Shoja was very knowledgeable and thorough. He checked our entire house for structural issues and concluded that the house was fine and didn't need underpinning!! They also don't carry put work that they recommend to avoid conflict of interest. I am so glad we found them, it has saved us tens of thousands of dollar of unnecessary work
Response from the owner:Lisan, we’re really pleased we could help you get a clear and independent assessment. Dr. Shoja was happy to take the time to check everything thoroughly, and it’s great to hear the outcome saved you from unnecessary work and expense. If you ever need guidance again, we’re here to help anytime! 𝐎𝐬𝐭𝐚𝐧𝐞𝐬 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠

FAQ & ENGINEERING GUIDE

About Our Knowledge Hub

The guides are written for Ostanes Engineering, a structural engineering practice working across South East Queensland. They explain common structural concerns in plain language.

No. The guides give general information only. Every building is different, so a cracked wall, a leaning retaining wall or storm damage should be assessed on site by a qualified engineer.

Width, direction, whether it is growing and where it appears all matter. Cracks that widen, reopen after repair, or come with sticking doors or sloping floors are worth having an engineer assess. Our crack and movement guides explain what to look for.

Yes. We provide structural inspections across South East Queensland, including Brisbane, Ipswich, Logan, the Gold Coast and the Sunshine Coast. Send the details through the contact form.
