Retaining Wall Dilemma

7 years ago

Our front retaining wall has seen better days & is in desperate need of replacement. Can anyone suggest a material & colour.
I have looked at treated hardwood- (lifespan is an issue), click together block work (not in love with the look)
The wall is 900cm high & 15 m long. We are looking to also level front yard & build a similar size wall behind the camellias to achieve this outcome.
Looking forward to any suggestions that are cost effective & look good.
Thanks

We went for dry stone stacked sandstone and are happy with the results. It is technically not dry stacked as it has some cement at the back of the wall but there are gaps for drainage and plenty of gravel behind. We live in an area where there is a lot of sandstone, whole house is built on it. You can see the natural rock ledge in the photos.

A landscape designer could give you options to suit your house and budget. There are structural issues, and drainage issues with retaining walls.

The only option really as Emily says is the the bottom left side wall of your plan. I wouldn't suggest putting it in front of the balcony - that's just not good circulation. And any ways you'd probably have a problem with electricity and plugging in your components and have wires all over the floor in front of the balcony. Put it on that wall and use a swivel mount so you can angle the TV around as you need to. You could also use a lift cabinet if you want to conceal your TV at times...

I would get rid of that pendant. Here's one link to industrial pendant lights http://www.houzz.com/industrial-pendants Pick a light that you like and show it to your landlord. I bet she/he will say yes to your suggestion since pendant lights can easily be changed. In fact, if there's already a really secure junction box there already i bet they may even go with a ceiling fan light combo if that's what you really want

Best to start with strong base or get a second opinion by having someone come on site and see the existing conditions.

I'd go with stone too. A boulder wall?

you can't go wrong with just replacing the wood and that is probably the quickest / cheapest but someone else bet me to my other recommendation with the pictures of the stones encased in mesh (above). This is a very modern look but I wonder will it be a weed collector in the future?

As you also plan to level your front lawn and build a second retaining wall, it'd be wise to consult a civil engineer and your Council. There will be issues of drainage (you don't want run-off going onto that footpath). And pressure of added earth and any plant roots against retaining structures will be significant.

Another vote here for sandstone. The boulders look great as does a dry stack.

I would check to see where front boundary actually is before going to far as it may or may not be where the existing wall is...... Also check local council regs for drainage requirements and check with engineer as it's usually any wall above 600mm needs to be engineered by a structural engineer. The landscaper will know all this but run it by them anyway. This is good looking house but landscaping will really make it a winner.

Hi there,

Our RIDGI range concrete sleepers and steel posts would be ideal for your retaining wall needs. They are sold throughout Bunnings stores in Australia, and designed for walls 900mm high and below. They are cost effective and have a warranty of 15 years unlike timber. We have a range of different styles for you to choose from too! Check out ridgi.com.au or visit your local Bunnings store.

Structural concrete retaining walls that contain water are great for storage and in fire prone areas can be an effective landscape solution and a life and property saver, we will be using these shortly in our Westernport Bay home in Victoria

It looks like the bricks in the retaining wall match your house bricks?

Assuming the brick columns have adequate foundation, I would look at getting concrete sleeper/ planks painted the same colour as your trim to replace the timber. Make sure there is geotextile, bidim a34, wrapped around washed 14 mm aggregate or Pea gravel behind your wall. Anything more than a metre high will need a design. For the second tier, you want to have it at least a metre or more behind the first wall, once again with adequate drainage behind. Remember to have the gravel connected to a subsoil drain which should be connected to the stormwater/ drain to the kerb

I quite like the idea of concrete sleepers for your retaining wall. They keep the modern mood. Not sold on Ridgi's faux timber look, though. If your drainage profile would allow it, continuing the brick of the pillars would look quite good, too. For me, the biggest landscape issue is the almighty fight happening between the two different sides of the driveway. You have the stick-up-the-rear formality of the camellia hedge fighting the looseness of the grass and shrubs on the other side. You need to decide on a single mood and go with that. Really!!

I'd go, actually, with a loose boulder or gabion wall with a planting behind it similar to that on the left (narrower) side of the driveway. Have a think about what you actually use that front lawn for, and if it's only there to keep the dirt from showing, add some trees and shrubs and underplanting. Shout yourself a tame forest! This will take up a lot of water if your climate's a bit wet, and stabilise the slope, too.

If you are thinking Gabions, you can see examples of our work on www.houzz.com.au/pro/prospectcontractorsaus or visit our Website.

Gabions are perfect for retaining purposes. They are strong yet flexible, accomodating ground movement. That are also permeable eliminating water pressure building up behind the wall.

Gabion would be my suggestion ultimately. Plenty of nice stone colour options to work well with the original brickwork on the house. Baskets can be stepped easily down the driveway and you could end up with an improved level area or two. The demolition of existing brick retaining wall can be absorbed in the Gabion baskets out of sight.

Thanks Annie Cass Landscapes, I completely agree with you about the conflicting styles of planting & have told the landscaper that is one area I need to rectify. May I ask who supplies the concrete sleepers you are referring to as the Ridgi ones suggested, didn't appeal to me either.
