Retaining walls in North Richmond
What we build around here.
North Richmond is growing Hawkesbury River town with new estates and established acreage. Terrain is typically hilly western side, flat riverside streets, sandstone bedrock on the hills.
North Richmond has exploded with new estates, and every one of them has sloped blocks that need retaining. We do a lot of new-build retaining walls here — terraced back yards, driveway cuttings, pool deck walls. Sandstone blocks look premium against the new render-and-face-brick homes that dominate these estates.

Questions North Richmond owners ask
Straight answers.
How much does a sandstone retaining wall cost in North Richmond?

Call Jesse on 0432 085 976 for a free North Richmond retaining wall quote.
What are the dimensions and weight of a sandstone block used in North Richmond?
Standard 2-metre sandstone retaining wall blocks used in North Richmond measure approximately 2000mm long by 400mm high by 400mm deep, and weigh around 1.4 tonnes per block. Both A Grade and B Grade share the same dimensions and weight — only the face finish and colour variation differs. Because the blocks are so heavy, every North Richmond sandstone wall is built using a purpose-made block grab attached to our 5.5t Kobelco excavator.
Where does the sandstone used in North Richmond come from?
The sandstone blocks Madden Earthworks installs in North Richmond are sourced from local New South Wales sandstone quarries, cut to 2-metre standard blocks, graded A or B on face finish, and delivered directly to your North Richmond site. Because the stone is locally quarried, the colour and texture match the natural sandstone already present under much of the Hawkesbury region — your wall ends up looking like it grew out of your block.
Do you service North Richmond for retaining walls?
Yes. Madden Earthworks is a Hawkesbury-based retaining wall specialist and North Richmond is a regular service area. We are based in East Kurrajong and travel across the entire Hawkesbury region. Call 0432 085 976 or fill out the quote form on this page and Jesse will organise a free site visit in North Richmond within 24 hours.
What type of retaining walls does Madden Earthworks build in North Richmond?
Madden Earthworks specialises in sandstone block retaining walls for North Richmond properties, using 2-metre A Grade and B Grade sandstone blocks. We also build concrete sleeper retaining walls with H-posts for longer spans or tighter budgets. Every wall we build in North Richmond includes proper drainage — aggregate backfill, socked agg lines to stormwater, geofabric, and engineered roadbase footings. Walls are pressure washed and all rubbish is removed from site.
How long does a sandstone retaining wall last in North Richmond?
A sandstone block retaining wall built correctly in North Richmond with proper drainage lasts 50+ years. Unlike timber sleepers (10-20 years) or concrete sleepers (20-30 years), sandstone doesn't degrade. The key is drainage: every Madden wall in North Richmond includes socked agg line plumbed to stormwater, aggregate backfill, and geofabric, which eliminates the hydrostatic pressure that would otherwise push a wall out of line.
Will a sandstone wall weather over time in North Richmond?
Yes, and it's one of the reasons sandstone suits North Richmond. Natural sandstone deepens in colour, shaded faces grow moss and lichen over time, and the wall settles into the landscape. A sandstone wall in North Richmond looks more at home at year 20 than at year 1 — the opposite of render blocks or concrete sleepers, which look their best on day one.
Do you offer free retaining wall quotes in North Richmond?
Yes. Jesse Madden (owner-operator) personally visits every North Richmond site to assess the job, identify drainage or access risks, and provide a fixed-price written quote at no charge. No obligation. Your quote typically includes all materials (sandstone blocks, roadbase, aggregate, agg lines, geofabric), delivery, excavation, block grabs, demo saw, operators, and clean-up. Call 0432 085 976 or submit the form on this page.
Is Madden Earthworks insured and licensed?
Yes. Madden Earthworks Pty Ltd (ABN 86 683 469 712) carries $20 million public liability insurance, is White Card certified, WHS compliant, DBYD (Dial Before You Dig) registered, and fully ABN registered. Certificates of currency are available on request.
How long does it take to build a retaining wall in North Richmond?
Most sandstone block retaining walls in North Richmond are completed within 2 to 5 days depending on length, height, access, and site conditions. Madden Earthworks typically schedules North Richmond jobs within 1 to 3 weeks of quote acceptance and a clear start date is locked in so you know exactly when work begins. Urgent jobs can often be accommodated — call Jesse on 0432 085 976.
Why do retaining walls fail in North Richmond?
The number-one reason retaining walls fail in North Richmond is poor drainage. Hawkesbury clay holds water, swells, and generates hydrostatic pressure that pushes walls forward until they lean or collapse. The second reason is inadequate footings — dirt-only bases settle unevenly. Every Madden sandstone wall in North Richmond uses compacted roadbase footings, a socked agg line to stormwater, aggregate backfill, and geofabric so these failure modes are eliminated from day one.
What is included in a North Richmond sandstone retaining wall quote?
A Madden Earthworks retaining wall quote for North Richmond is fully inclusive: excavation and site prep, roadbase footings, 2-metre sandstone blocks (A Grade or B Grade), block deliveries, aggregate drainage behind the wall, socked agg lines plumbed to stormwater, geofabric, 5.5t excavator and operator, sandstone block grabs, demo saw for block cuts, skilled labourers, pressure wash on completion, and removal of all rubbish from site. No hidden extras.
