Concrete blocks are one of the most effective methods of creating a retaining wall. Especially when using Interlocking Concrete Blocks. But does this extra level of effectiveness mean that it will be more expensive than traditional materials?
In this blog, we will answer the question ‘How much does concrete block retaining wall cost?’
Monthly construction output had risen an estimated by an 1.6% value in June 2023, and we would like to think our accessible concrete products had a small part to play by giving our clients easy access to reliable and easy-to-use construction solutions.
The importance of a retaining wall
Retaining walls can be a necessary or optional feature that can be implemented in gardens, public areas, essentially anywhere with a natural hill. A retaining wall organises the land and has the potential to create level ground on once sloped areas. Retaining walls can be tall, or small.
Retaining walls become necessary in instances where the land is at risk of landslides. This can be implemented in natural areas that are frequented by the public, including nature trails etc. This shows that retaining walls are more than just an aesthetic addition to a landscape, they can be vital to public safety.
Benefits provided by retaining walls
- Prevent soil from collapsing or eroding.
- Provide protection for a building (e.g. if a house is located on a higher platform, and it is in danger of collapsing after a flood or earthquake.
- Offer protection for your natural vegetation.
- Improve the appearance of your garden landscape, which therefore boosts the value of your property.
- Help create a seating area in your garden, which will be comfortable and relaxing.
- Allows you to put raised planters on top of the retaining wall, which adds beauty and colour to your garden.
- Help reduce run-off of water after storms.
- Eliminate piles of dirt, debris, or sand, which look unsightly.
- Help divert rainwater, which can be utilised in your home or garden.
- Prevent sinkholes, which will damage your landscape structure.
- Be used for flood control- as you can incorporate drainage pipes into the wall, for drainage and water control.
How much does concrete block retaining wall cost?
Concrete block retaining walls can vary heavily on price, this is due to two key factors which are…
- The size and type of concrete blocks you choose.
- The amount of concrete blocks required.
Furthermore, you have to consider additional factors that will contribute to the total price of constructing a concrete block retaining wall. If you are, these additional factors are…
- Excavation for the footings.
- Gravel for drainage.
- Services of builders.
- Cost of renting equipment.
If you are using the services of a landscaper in order to organise the construction of a retaining wall, please note that the prices of the resources will vary purely based on whom they opt to buy from.
If you are considering using Interlocking Concrete Blocks in the construction of your retaining wall, simply get in touch with us to receive an accurate quote. All we require from you is the measurements of the project at hand.
Ideally, at the minimum, we would like to know the intended height, and length of the retaining wall.
By getting this information, we can discuss the appropriate options we can provide for you, which can then lead to an accurate quote.
How much do interlocking concrete blocks weigh?
In regard to the weight of the blocks, it will vary from size to size, and from the concrete being used. But as an example, 1800 × 600 × 600 concrete block can weigh 1560 kg, this can fluctuate as different types of concrete have different levels of density.
Can you use a concrete barrier to create a retaining wall?
No. The concrete barriers that we supply are not shaped in a way that allows them to be stacked upon each other. Additionally, their interlocking feature is only on the sides of the barrier, rather than on the tops and bottoms. Although they are heavyweight, they are not appropriate to be used to create a retaining wall.
Disadvantages to using Interlocking Concrete Blocks for a retaining wall
The disadvantages that are presented by using interlocking concrete blocks for a retaining wall only present themselves if there is inadequate planning done beforehand. Here are the issues that can present themselves…
- Interlocking Concrete Blocks are made to order. This means that if you order fewer than you actually require, you may be waiting to receive the remaining amount you need, which will delay your build.
- Once the blocks are interlocked, it can be extremely difficult to detach without mechanical assistance.
- If the weight behind the wall increases exponentially, either purposely, or because of water retention due to inadequate draining, it could lead to the retaining wall slanting over time.
- The aesthetic of concrete blocks are limited, which means personalisation, such as painting would require extra work, although we have rock face block options available too.
Advantages of Interlocking Concrete Blocks
The advantages of Interlocking Concrete Blocks far outweigh the negatives, even when it comes to making a retaining wall. The main advantages of Interlocking Concrete blocks are…
- Heavyweight – The naturally heavy makeup of Interlocking Concrete Blocks means they can easily support more weight using fewer blocks than a traditional brick retaining wall would.
- Durable – Concrete is tough by nature, it can withstand moderate to heavy impacts, retaining walls aren’t usually made in areas where they are subject to regular impacts. So knowing they can withstand impact grants additional peace of mind, wherever it is set up.
- Time efficient – The fact that Interlocking Concrete Blocks do not require mortar to establish a firm and reliable connection means that setting them up is more time efficient than using cement and waiting for it to dry.
- Long-Lasting – Alongside the fact that Interlocking Concrete blocks are durable, they are also weatherproof and fireproof too. Due to these features, concrete can last for a number of years.
Can you use wood for a retaining wall?
Wood can be used for a retaining wall. Although it is a reliable material to use for a retaining wall, it isn’t as good of a material compared to Interlocking Concrete Blocks. Here is a list of pros and cons that are provided by a wooden retaining wall.
Pros and cons of a wood retaining wall
Pros of a wooden retaining wall include…
- Cheaper and an easily available resource.
- Can be cut on-site to alter sizes.
- Can be customised via painting or decorating.
- Has the potential to be weatherproofed.
- Provides a natural and bespoke aesthetic.
Cons of a wooden retaining wall include…
- It has a low durability and susceptible to heavy impacts.
- Can be affected by weather.
- Lightweight, meaning it will be difficult to hold back weight unless it has reinforced by a firm foundation.
- The wall can slant over time if there is inadequate drainage.
