Earthworks & Retaining Walls Perth
A sloping block, a retaining wall that leans more than it used to or a new build sitting on nothing but sand. Perth’s northern suburbs throw up a range of earthworks and retaining wall challenges: sandy soil doesn’t hold a slope on its own, coastal exposure works against common materials and a wall built to subpar standards is a repeat problem to deal with.
Methods and materials tailored to the actual conditions of your block.
Walls above a certain height need a WA building permit. We handle the paperwork so you don’t need to.
From site assessment to final walkthrough, you’ll deal with the same people.
Why Perth's Northern Suburbs Need Retaining Walls Built Right
Sloping blocks are common across the northern suburbs and so is sandy soil that won’t hold a slope without help. Add coastal exposure in suburbs like Two Rocks, Alkimos and Quinns Rocks and you’ve got conditions that punish a wall built to a budget rather than a standard.
The practical problems tend to look familiar. A limestone wall that was never properly footed and has started to lean. A block too steep to landscape until the levels are sorted out. A new build where the yard is nothing but sand because the scope stopped at the slab.
What’s frustrating usually isn’t the wall itself. It’s not knowing whether the quote you’re looking at actually covers what needs to happen or whether council approval is about to add months to your timeline. You want a straight answer on both before you commit to anything.
Kinetic Landscaping has been building and replacing retaining walls across Perth’s northern suburbs for over 25 years. We’re members of the Landscape Industries Association WA, and we understand the sandy soil and coastal exposure that shape how a wall needs to be built here.
Retaining Wall & Earthworks Services We Offer
A retaining wall or earthworks project rarely involves one thing. We scope the entire job, from the wall itself to site levels and drainage provisions so nothing gets missed.
Limestone Retaining Walls
Perth’s most common retaining wall material, built and pointed properly so it stays stable for decades, not just until the first heavy winter.
Retaining Wall Replacement
Full replacement of cracking, leaning or failing retaining walls, built this time so it doesn’t need doing again. We’ll assess your wall and scope the replacement as part of your project.
Earthworks & Site Levelling
Excavation and site levelling for blocks that need reshaping before any landscaping or construction can start, scoped around your finished design.
Excavation & Earthmoving
10-tonne excavator capability for civil-grade site works from small residential digs through to larger commercial and multi-stage projects.
Cap Rock Removal & Site Preparation
Removal of cap rock and other obstructions common on northern suburbs blocks, cleared properly so the ground underneath is ready for the next phase.
Drainage & Groundworks
Drainage built into the retaining wall or earthworks scope from the start, so water is directed away from the structure instead of undermining it over time.
Why Choose Kinetic Landscaping For Your Retaining Walls & Earthworks
A retaining wall holds back an entire slope and a wall that fails causes major issues. Here’s what makes the difference with Kinetic Landscaping.
Built For Perth’s Conditions, Not A Generic Spec
Sandy soil, cap rock and coastal exposure all change how a wall or excavation needs to be handled. We build for the conditions on your actual block.
We Manage Council Approval, Start To Finish
Retaining walls above a certain height need a building permit in WA. We flag what’s required at the quoting stage and manage the process on your behalf.
You Deal With Bel & Jeremiah Directly
The same two people who assess your site are the ones accountable for the finished result. You’ll never deal with a rotating crew of subcontractors.
Real Results From Real Projects
From Bushland Building Site to a Garden That Flows Two Rocks Family Garden
When the house was being built, the block was still raw bushland: sand, cap rock and dust, with construction access cutting straight through what would eventually become the garden.
The brief was to hold onto everything that made the site special, the native bushland and the birds it attracted, while building a garden the family could actually live in.
From Undeveloped Block to Purpose-Built Lifestyle Property Gingin Acreage Makeover
This Gingin project involved transforming a one-acre property that had never been landscaped beyond the construction of the home. The block was largely undeveloped, overgrown and lacked structure or usability.
Our goal was to convert the space into a fully functional acreage, with clearly defined zones designed for purpose, lifestyle and long term enjoyment – ready for the clients to move into and enjoy in retirement.
From Sand Dune to Magazine-Worthy Outdoor Living Two Rocks Coastal Transformation
This Two Rocks project began with a newly purchased coastal home sitting on a typical sand dune block – minimal usable yard space, failing retaining walls and challenging site conditions.
Our brief was simple yet impactful: transform the property into a functional, welcoming outdoor environment that felt like home and made the most of every square metre.
What Our Clients Say
View review on GoogleKinetic did a fantastic job removing our old, poorly constructed landscaping. They were able to overcome the challenges of a very wide awkwardly sloping block (old unretained Alkimos Beach) to ensure the replacement limestone walls and paving looked natural and aesthetically appealing. They were happy to adapt to some design changes along the way with zero fuss and ensured everything was left tidy and clean before leaving. We have already received positive reviews from the neighbours. If you have to wait a while for availability, it’s worth the wait to get it done properly.
View review on GoogleHad a flawless experience with Jera and Bel from Kinetic Landscaping. The work they did was amazing and I couldn't be happier. They accommodated all of my procrastinating with making decisions and were spot on with communication. The space has been transformed from bland to beautiful. Now I just have to furnish with plants and some comfy chairs and that's where you'll find me. Would absolutely recommend if you want top quality workmanship.
View review on GoogleBel and Jeremiah from Kinetic Landscaping have done an amazing job installing our travertine pavers out the back and up the side of our house. Their workmanship was excellent, and the results look fantastic. They were lovely people, very easy to talk to, and made the whole process a breeze. We’re extremely happy with the result and would highly recommend them to anyone looking for quality landscaping work!
View review on GoogleKinetic's lovely team totally transformed our desolate front yard into this thriving garden. Not a simple thing to achieve for beach side properties. Upkeep is so easy now. Should have done it 10 years ago. Absolutely recommend.
View review on GoogleI’m so glad we chose Kinetic Landscaping to landscape the front of our new build in Yanchep. Jeremiah, Bel and their team transformed a sloping sand pit into the best frontage on our street. It was a big job and we had a few challenges along the way due to soak wells and service lines not being where the plans said they were going to be but Jera provided us with options for how to overcome it and the end result was better than we had originally planned. The Kinetic team installed a retaining wall with terraced garden beds and completed the job with a zoned retic system, lawn installation, soil improver, planting, stone laying, bird bath installation and paving a space for our bins, finished off with a one of a kind Kinetic letterbox. Bel took time to go through my vision with me in detail and then the team executed it to look even better than we could have imagined. Jera is an expert of his trade and it showed in everything he suggested and executed on. The team are friendly and considerate, they did a fantastic job tidying up each day and are always happy to have a chat and explain to you the details. If you’re looking for landscaping, look no further than Kinetic, you won’t be disappointed.

Our Proven Process
Getting your retaining wall or earthworks project underway starts with a simple conversation. Here’s how it works.
Step 1 – Tell Us About Your Project
Fill in our quote form, it takes a couple of minutes and covers your block and its problem and what you’re hoping to achieve.
Step 2 – Onsite Consultation
Bel or Jeremiah will assess your site in person, checking the slope, soil, any existing structures and whether council approval applies to your project.
Step 3 – Detailed Scope & Quote
You’ll receive a clear quote with no hidden costs. We’ll flag any council approval requirements, confirm the wall type or earthworks scope, and give you a realistic timeline.
Step 4 – We Get To Work
From the first day of excavation through to the finished wall, we keep you in the loop across the project. The result is a retaining wall or levelled site built to hold.
Retaining Walls & Earthworks Across Perth's Northern Suburbs
We build retaining walls and earthworks across Perth’s northern suburbs, with deep experience on the sloping, sandy and coastal blocks that make up much of the region. If your property is in Alkimos, Eglinton, Yanchep, Two Rocks, Quinns Rocks, Mindarie, Clarkson or Joondalup, you’re in our service area.
One recent Two Rocks project involved a coastal block requiring more than 150 cubic metres of excavation and retaining structures across multiple levels, managed alongside council approval and full trade coordination from start to finish. That’s the scale of earthworks and retaining we’re set up to handle, alongside smaller single-wall jobs.
Frequently Asked Questions
Do I Need Council Approval For A Retaining Wall In WA?
In most cases, yes, once a wall exceeds a certain height or sits near a boundary. The exact threshold depends on your council and your block. We manage the approval process on your behalf as part of the project, and we’ll flag what’s required at the quote stage before any work begins.
How Much Does A Retaining Wall Cost In Perth?
It depends on the wall type, height, length and site access. We give you a clear, itemised quote at the consultation stage with no hidden costs added later.
Do You Replace Existing Retaining Walls As Part Of A Project?
Yes. At the onsite consultation, Bel or Jeremiah will assess whether your existing wall needs replacing and scope it in alongside the rest of your landscaping project. We pride ourselves on giving you a straight answer on what’s genuinely required.
Do You Handle Site Levelling And Excavation As Well, Or Just The Wall Itself?
Both. We scope retaining walls and earthworks together where a project needs it, groundworks, levelling, drainage and the finished wall, so you’re not coordinating separate contractors or sequencing the work yourself.
How Do You Deal With Cap Rock Or Particularly Sandy Blocks?
Both are common across the northern suburbs and both change how a site gets prepared. Where possible, we identify cap rock at the site assessment stage so it’s factored into the quote from the start. If it’s only discovered once work is underway and removing it would blow out the budget, we’ll talk you through the options. Sometimes it makes more sense to adjust the design around it than to remove it. Sandy blocks need the right groundworks so the finished retaining wall has something solid to sit on and we factor this in from the beginning too.
