Planning and Building a Retaining Wall

Many residential and commercial properties require retaining walls for various reasons. A well designed and installed retaining wall can improve safety, aesthetics, and functionality, and can even add value to your property. If you want to install, repair, or replace a retaining wall, the right preparation and equipment will ensure a professional finish. For Bobcat hire, Mornington Peninsula homes and business can rely on Bittern Garden Supplies. Read on to discover more about retaining walls and a few things you need to keep in mind when building one.

What is a Retaining Wall?

Simply, it is a structure built to contain soil at different levels on two sides. In other words, it retains soil that would otherwise drift down and potentially erode over time. It makes the land level and useable for other structures, projects, garden beds or even just a spacious backyard.

When to Build a Retaining Wall

Typically found on sloping sites, they are often built to clear space for a particular feature such as a pool, driveway, or outdoor entertaining space. They are ideal for those looking to maximise their usable land. While these rigid walls serve a functional purpose, they are often used to create garden beds or planter boxes to add visual appeal to a backyard or public space.

Things to Consider

If you’ve decided that you need a retaining wall, there are some things you need to consider:

Equipment – You’ll most likely need an excavator or Bobcat and a compactor, and you might also need a mini dumper and specialised attachments such as a hydraulic rock breaker, auger, and/or concrete sleeper grabber. The exact machinery and equipment you’ll need depends on the type of soil and the type of material you plan to build your wall from.

Planning and Permission – Check with your local council regarding their regulations on retaining walls. Depending on the height and position of the wall, you may need building approval before you begin. Check plans for any existing underground pipes or cables. Draw up your desired wall ensuring the measurements are correct and make a note of the number and size of posts that you’ll require. The space between posts is suggested to be around 1200mm and around half the length of the posts will be below ground level – this means that a 900mm high retaining wall will require 1800mm posts. If you’re planning on working with a large amount of earth, you should consult an engineer.

Drainage – Retaining walls must contain appropriate ground water drainage behind the wall to relieve water pressure. Professional drainage contractors will be able to install an adequate drainage system to ensure your retaining wall is safe.

Materials – Commonly built from concrete blocks, treated timber sleepers, rocks, or bricks, however, there are many options that you can consider. The best material will be one that suits your budget, and the look you’re trying to achieve. It’s important to keep in mind that timber may be a cheaper option, but they may not last as long as sturdier materials such as rock or concrete.

Footings – You will also need to consider the best material for the base or footings. The base supports the integrity of the wall so it’s important to get it right. The type of base you need depends on the condition of the soil you’re building on top of and the type of retaining wall being built.
