High-End Retaining & Excavation

Retaining walls built to a standard, not a price.

Align Excavation Group builds high-end residential and civil retaining walls the right way. Excavation, engineered drainage and structure, all handled in-house by one owner-led crew.

We specialise in retaining wall and site works projects from $30,000 and up. If that sounds like your project, leave your details and Hannah will call you back the same day.

A large wall is holding back tonnes of soil and everything built above it. It deserves to be engineered, not just stacked.

That is the difference between a wall that looks finished on handover and one that is still holding straight in twenty years.

01 — Why big walls fail

Most big walls don't fail on day one. They fail a few years later.

When a large wall is priced as a cheap job instead of built to a standard, the corners that get cut are the ones you cannot see, until it starts to lean, crack or blow out.

  • i. Posts and footings not set deep enough for the soil load and wall height
  • ii. No proper drainage behind the wall, so water builds up and pushes it out
  • iii. Poor excavation and site prep before a single sleeper goes in
  • iv. No engineering on walls that clearly need it

The materials are rarely the problem. It is the ground underneath that decides whether it holds.

02 — The difference

An excavation crew that builds walls, not a wall crew hoping the ground holds.

Most retaining jobs sub out the dig, the drainage or both. We do the lot in-house, so the ground, the structure and the finish are all held to one standard by the same crew.

  • 01 Full excavation, cut and site prep done in-house, not subbed out
  • 02 Engineered drainage built in behind every wall, not an afterthought
  • 03 Posts and footings set for your soil load and wall height
  • 04 Experience on large residential and civil work, not just garden walls
  • 05 Mitch runs every job on site, from the first dig to the last course

A wall is only as good as the ground it sits on. We control both.

Proven on serious jobs

Built for the jobs that leave no room for error.

Align works across high-end residential retaining walls, large civil projects and site works most crews will not take on. The bigger and more exposed the job, the more the details underneath matter, and that is exactly where we are at our best.

4
Scope & price
A proper scope and price, with engineering and permits organised where required. No vague ballparks.
5
Build
We excavate, drain, build and finish, with a full clean-up and a final walk-through.
04 — Built to last

We focus on what you can't see. That is what makes it last.

A wall of this size is a major investment. What decides how long it lasts is not the finish. It is the excavation, the post depth and the drainage, all set before a single sleeper goes in.

  • 01 Site excavated and prepped correctly for the load
  • 02 Posts and footings installed to the right depth for your soil
  • 03 Proper drainage system behind the wall, not an afterthought
  • 04 Engineered and permitted where required, to code from day one

05 — Questions

Good to know.

What size projects do you take on?
We specialise in retaining wall and site works projects from $30,000 and up. That focus lets us do the excavation, drainage and structure properly and give every job the attention it deserves.
What areas do you service?
We are based in the Yarra Valley and cover Melbourne's east and surrounds, and we travel for larger civil and site works. Not sure if we reach you? Call us and we will let you know.
Do you do the excavation as well as the wall?
Yes. Excavation, cut, site prep, drainage and the wall itself are all done in-house by the same crew. Nothing critical gets subbed out, so the whole job is held to one standard.
Do you handle permits and engineering?
Yes. For walls above a certain height or load we work with qualified engineers and organise the permits and approvals, so your wall is compliant and built to hold.
What materials do you build with?
Concrete sleepers, treated timber sleepers and rock walls are the most common. We recommend the best option for your site, the look you want and the load the wall needs to carry.
How long does a wall take to build?
It depends on the size, the site and how much excavation is involved. We give you a clear timeline as part of your scope and price before any work starts.
