1
Record height and length
A rough face area helps compare systems, while the maximum retained height can change the approval pathway.
Retaining Wall Checklist Ipswich
Prepare the facts that make a wall discussion useful, from levels and loads to drainage, access and records.
Method and Assumptions for a Retaining Wall Ipswich Checklist
This checklist is a preparation method, not a design, approval assessment or construction scope. Work through each item before requesting prices because an unchecked assumption can alter the wall system, approval pathway, construction method or final cost. Confirm local approval questions with Ipswich City Council.
2
Photograph both sides
The wall face alone may hide a driveway, building, pool, fence or second wall adding load above it.
3
Mark the property boundary
Footings, drainage and the wall body need to remain within the correct property unless a documented agreement says otherwise.
4
Trace roof and yard water
Downpipes and surface runoff directed behind a wall can create pressure that damages even a strong wall.
5
Find the drainage outlet
An agi pipe is only useful when it falls to a lawful outlet rather than discharging onto a neighbour.
6
Check machinery access
Gate width, side clearances, steps, paving and overhead obstacles affect excavation, spoil removal and material handling.
7
Describe the retained load
Soil alone is different from a driveway, building platform or pool, and surcharge can trigger engineering at lower heights.
8
Compare material life and finish
Timber, concrete sleeper, block, rock and gabion walls solve different structural, drainage, maintenance and appearance priorities.
9
Ask about reactive ground
Ipswich clay can expand and shrink with moisture, so footing and drainage assumptions should reflect the actual soil and wall.
10
Confirm engineering and approval
Do not rely on height alone. Proximity, surcharge, combined structures and site conditions can change the requirement.
11
Get the scope in writing
Materials, drainage, excavation, disposal, approvals, exclusions and final levels should be clear before work begins.
12
Verify provider credentials
Where regulated work applies, check the relevant licence and make sure the operator carrying out that work holds it.
13
Plan inspections and records
Keep drawings, certificates, approvals, drainage photos and product details for maintenance and a future property sale.
14
Agree on site protection
Existing fences, gardens, paving, services and neighbour-side conditions need a plan before machinery arrives.
