Benefits of Link Block Mortarless Retaining Walls
There are a huge number of benefits to be had when using these retaining wall blocks, and they include:
- The retaining wall blocks stack on top of each other and do not require any mortar or cement joins. This obviously makes construction much easier and means that the home handyman can produce a quality outcome. In fact there have been some comparisons made with good old-fashioned “Lego” where once the bottom course is laid, the retaining wall blocks just click together!
- Following on from this point; if a mistake is made … as there is no mortar, you can just dismantle the retaining wall blocks and start again.
- In most cases, the retaining wall blocks are below 20kg each which again makes installation possible by you. No need to be “Mr Muscles” to get your retaining wall blocks around the back!
- As they are a manufactured product, their sizing and uniformity is very consistent, again making installation a breeze.
- Depending on the style of retaining wall blocks chosen, they can be used in straight or curved walls and in many cases can do right-angled corners too.
- Given the variety of styles and colours available, they can blend in with any style of landscaping project.
- There are styles that build vertical retaining walls and some that slope backwards into the bank to give more strength and there is even a style that is hollow, allowing you to fill them with soil and plant them out … giving a rockery type appearance.
- We quite often have a great range retaining wall blocks at discounted prices making them a very economical option.
Things to be cautious of when using Link Retaining Wall Blocks
- It is a good idea to read the manufacturer’s guidelines as to the capabilities and specifications of the retaining wall blocks. Some of the biggest problems arise when retaining wall blocks are used for an application that they are not designed to handle, e.g. over a specified and designed height or right angled corners, etc.
- In spite of modern technology, all these retaining wall blocks have the potential to fade to varying degrees over the years and depending on their location, they may well succumb to some mould growth on the surface. These are processes that happen naturally and cannot be avoided, however, the retaining wall blocks do respond well when cleaned with a gurney or high pressure cleaner.
- If the bottom course is not laid level and carefully, this can result in the retaining wall appearing uneven, as each course will follow the pattern of the one below. Ensure extra care is taken laying the bottom layer and have a spirit level available at all times!
- Consider the stability of the ground when planning the footing below the retaining wall. Some brochures recommend compacted road base which can be fine for small retaining walls (say around 50mm) but on higher walls, up to 1m, the use of concrete (a mix of Concrete Blend and Cement) is a much better idea as it not only strengthens the retaining wall base a great deal but also ensures that each level stays exactly level for the life of the retaining wall.

The colours shown should be taken as indicative. They are as close as photographic processing and computer monitors allow. Decisions on colour should be made from actual product.
Colour tonal and shade variations are an expected part of all natural stone and man-made retaining wall blocks. These subtle colour variations between retaining wall blocks add interest and life to a finished retaining wall.
There can be small variations from block to block, batch to batch and therefore from samples to retaining wall blocks. Because of water absorption and concrete curing, retaining wall blocks can sometimes lighten a little over time and darker markings may occur.
