How to Discover If you have Best Quality Limestone for Walls?

It’ll probably come as no great surprise to discover that there are different types of limestone and even within a given type, different qualities.

Not all limestone is equally suitable for all purposes.  It takes skill and experience to decide which is most suitable in a given set of circumstances. Of course, ultimately the final decision must rest with the customer but at Downunder Contracting we believe in providing as many facts as possible to help you make those decisions.

So, here is a very brief overview of limestone walls. Albany property owners might find this useful.

Reconstituted limestone

As the name suggests, this is a composite that’s made with limestone and various other materials.

It’s strong and can be treated, as part of the process, to reduce the chances of discolouration and corrosion. Some might argue that makes it less of a natural product than untreated varieties but it can be stronger and more durable than natural stone.

Natural limestone

The name says it all. This stone is wonderful and largely natural – though it can be a little vulnerable to discolouration and corrosion in areas that are vulnerable to acid rain.

The good news is that it can be treated to reduce that vulnerability and it can also be stained various colours to fit in with your natural landscape or wider decorative needs.

Cladding for walls / floors (limestone tiles)

Limestone can be polished to give a brilliantly smooth finish then cut into cladding or tiles.

Remember that different thicknesses of tile are required for different purposes. Generally, wall tiles can be thinner than those on the floor – particularly if the floor areas are going to take a lot of traffic.

Overall quality

Warring signs relating to poor quality in any limestone might include:

  • Significant amounts of red or brown discolouration when new.
  • Irregular sized blocks or tiles – this suggests poor quality control.
  • Significant holes in the limestone. Some holes are perfectly natural but should be filled and expertly polished out – particularly on tiles.
  • Lots of graining and surface pitting. A little might be perfectly natural but if the stone looks like it could be used for sanding purposes then it might suggest it’s either poor quality or has been poorly prepared.

We only use the very highest quality materials and we’d be happy to clarify our selection criteria.
