Retaining walls provides structural retaining to boundaries where neighbouring sites have higher or lower levels than the proposed construction site. The wall is designed to resist soil from spilling over to the neighbouring site or soil being spilled unto the construction site.
There are several different types of retaining:
Concrete panel and post is the most common form of retaining due the ease of installation and cost. There is a maximum height of 1800mm this method can be utilised.
Engineered designed Limestone walls are constructed to provide specific structural requirements. They are more commonly used when retaining is over 1800mm or when required to be load bearing.
Mass brick retaining or concrete cavity filled walls are constructed to site-specific requirements and an engineer’s design. They are designed to hold back soil that is higher or lower than the footing level.
“Brick builds ups” are required when there is different levels within the building site. Usually they are constructed in formed concrete walls or brickwork with concrete cavity fill to hold back soil higher than the footings.
In some instances, there will be a requirement for retaining walls within the building area due to “terracing” or sloping sites.
A retaining wall is required in the following circumstance:
- Your neighbouring block is higher than yours.
- Your neighbouring block is lower than yours.
- Your are building on a sloped block.
- Retaining walls can also be used for terracing and garden edging.
- The retaining ensures the soil from the higher ground does not fall into the lower site, in addition to help prevent soil erosion.
What is Limestone Retaining?
Limestone retaining wall blocks are usually made of crushed limestone mixed with concrete to give the blocks more strength and to last longer.
Limestone walls are more commonly used when retaining is over 1800mm or when the wall is required to be load bearing.
They are constructed to provide specific structural requirements on the site.
What is Panel and Post?
Panel and post is made of concrete and is the most common form of retaining wall due to the ease of installation and lower cost.
The posts are positioned into holes and secured. The panels are slotted in between to a maximum height of 1800mm.
