Drainage Inspection and Stormwater Advice for Homes in Brisbane
If water is getting under your house, around your foundations, into lower rooms or leaving damp areas that never seem to dry, Cornell Engineers can provide practical structural engineering advice to help you understand what may be happening and what to do next.
This service is for homeowners who need calm, practical advice before spending money on builders, plumbers, landscapers, drainage contractors or major repairs. It is not full civil drainage design. It is a sensible engineering inspection and advice service for real houses with real water problems.
Water under your house can be stressful. We help you make sense of it.
Water under a home is not usually something people search for casually. Most homeowners start looking for help because something feels wrong. The subfloor may smell damp. Water may run under the house after heavy rain. Bricks may be fretting. A lower room or granny flat may be getting wet. Or the ground around the house may stay soggy long after the rain has stopped.
Cornell Engineers provides practical drainage inspection and stormwater advice for homes in Brisbane and South East Queensland. We inspect the accessible areas, consider the likely contributing factors, and provide clear advice about possible next steps.
The aim is simple: help you understand whether water, drainage or subfloor moisture may be affecting your home, then give you a practical starting point for repairs, improvements or further specialist advice.

This is practical engineering advice, not full civil drainage design
It is important to be clear about the scope. This service is intended to provide practical structural engineering drainage advice for homeowners. It does not automatically include detailed hydraulic or civil drainage design.
This service does not automatically include:
- Detailed hydraulic design
- Contour survey
- Plumbing design
- Drainage construction drawings
- Geotechnical investigation
- Flood modelling
- Certification of completed drainage works
- Council stormwater approvals
- Design of major civil drainage systems
If further input is required from a plumber, drainage contractor, builder, landscaper, geotechnical engineer, hydraulic engineer or surveyor, we can identify that in the advice. Sometimes the best value an engineer provides is helping you avoid spending money on the wrong fix first.
Why involve a structural engineer?
Drainage issues around houses are not always just plumbing problems. Water can affect footings, subfloors, retaining walls, brickwork, timber framing, lower rooms and the long-term performance of the building. A structural engineer can look at the issue with the building in mind, not just the pipework.
Cornell Engineers does not replace the role of a good plumber or drainage contractor. Instead, we help you understand the problem from a structural and practical point of view so you can make better decisions about what to do next.
Frequently asked questions
Can Cornell Engineers tell me if water under my house is damaging the structure?
We can inspect accessible areas and provide advice about visible signs of moisture-related issues, deterioration or structural concerns. If further investigation is needed, we may recommend additional specialist input.
Do I need a plumber or a structural engineer first?
It depends on the problem. If the issue appears to involve roofwater pipes, stormwater connections or plumbing defects, a plumber may be required. If you are worried about the building, subfloor, brickwork, footings or long-term structural effects, an engineering inspection can be a sensible starting point.
Do you design full drainage systems?
This service is for practical drainage inspection and stormwater advice. Detailed hydraulic design, civil drainage drawings, flood modelling and council drainage approvals are not automatically included.
Can this help before I speak to a builder, landscaper or drainage contractor?
Yes. Many homeowners want independent advice before they start getting quotes for drainage works. A practical engineering advice report can help you understand the likely issues and the type of work that may need to be considered.
