Limestone Wall Cracking

Limestone retaining wall crack repairs

Bunbury

To capture the views of the coastline in Bunbury, it's very common for properties to be built up using limestone retaining walls due to being a natural product, hard wearing against the effects of the salty air and usually requiring little to no maintenance.

Unfortunately for the Owners of this property, their limestone retaining wall had developed cracking over time and needed a solution to prevent the situation from deteriorating further.

As it was found the cracks were mostly a result of settlement, they first had the foundations underpinned to stop the movement before asking us to address the cracking in the limestone blocks.

Due to the cracking going straight through as opposed to following the mortar joints of the blocks and their size, we installed the larger 9mm x 1m Thor Helical crack stitching bars and 6mm bars in longer lengths where needed to tie larger sections together and stabilize the walls.

The 9mm bars were more appropriate in this situation due to their ability to carry more load per bar even though they share the same tensile strength properties as the 6mm.
