Natural limestone blocks are cut directly from the floor of the quarry whereas reconstituted limestone is a manufactured product made by using high quality crushed limestone and cream cement that preserves the look and feel of natural limestone but has the added strength and superior qualities of a manufactured product which doesn’t crumble or discolour over time.

Reconstituted Limestone






Natural limestone is a porous stone and if subjected to damp and wet conditions creates an appropriate environment for lichen, algae and/or moss to grow. If the growth is not removed in its early stages it may darken the stone. Dark soils may also darken natural limestone. Reconstituted limestone does not discolour to the same extent because it is not as porous.
Consider what the blocks are to be used for, the size of the project and the desired end result. The block used for a garden bed will be totally different to that required for a retaining wall.
Freestanding Wall: 

A freestanding wall is not a retaining wall as the level of earth is even on both sides, and in most cases will require some form of footing/foundation.  Piers may be required.


Retaining Wall: 

A retaining wall is designed to hold back material such as sand, gravel, rock etc.  The stress on a retaining wall can be increased when it rains as the water content builds up behind the wall.  This is why some walls require drainage. There is a rule of thumb which says that the thickness at the base of the wall should be equivalent to 50% of the height of the wall i.e. a wall 1200mm high would be 600mm wide at the base.  This rule does not apply to walls that support the weight of pools, buildings or traffic etc.

Perth Trade Centre can arrange to have a structural engineers report for you to submit with your council building permit. We can also arrange for a land survey to be done.

Different councils have different guidelines when determining whether planning permission is required.  In most cases, if a wall is 500mm or higher, then council planning permission is required.

Yes, we arrange third party delivery to your site. Most blocks are delivered on pallets, excluding 1000x350x350mm blocks which are delivered in pack form. We normally place the blocks on the property verge.  Sometimes we may go beyond the verge but only with the permission of the customer. If permission is given, Perth Trade Centre accepts no responsibility for damage caused whilst proceeding beyond the property line.
Our products are manufactured using natural raw materials, therefore there will always be a variation in texture between one block and the next; this is what makes them unique.
It is essential that your limestone blocks are thoroughly cleaned once laid and prior to any application of any sealer (optional).  Installation of you limestone blocks can involve contaminants including yellow sand, cutting dust and mortar residue so it is inevitable that some marking may occur. Other marking could occur due to boot or wheelbarrow management and efflorescence. None of this marking is permanent.  Correct cleaning of your product and using a professional sealing contractor will ensure that stains are removed. We recommend the use of a high-pressure water cleaner with soapy water. We do NOT recommend using acid to clean your newly installed limestone blocks and under no circumstances should you place any acid (or strong alkali cleaner) onto the surface of your limestone blocks to remove efflorescence, stains or mortar marks.
You do not have to seal your limestone blocks, however we do recommend sealing to maintain the original look of your project and recommend the sealer is reapplied every 12-18 months.
Reconstituted limestone is a manufactured product and does not turn black with age like natural limestone.  It does, however, discolour as a result of other elements such as mineral deposits in bore water or mineral deposits/dirt transported by the wind or other means.  Sealing will reduce the likelihood of discolouration.
We recommend Klen International Tel: (08) 9302 4000, located in Wangara WA, who specialise in cleaners and sealing products.
The white powder that appears on the limestone pavers or blocks is called efflorescence. This is a temporary condition caused by salt/ minerals rising to the surface of the product, usually drawn out by water in the mortar drying during installation, bringing the natural salts from the limestone to the surface and crystallising. Do not attempt to clean the deposit with chemicals or industrial cleaners as it may damage the surface of the limestone. The best option is to brush the surface with a broom and rinse with water. Efflorescence will dissipate over time.

If for any reason the products you receive do not meet Perth Trade Centre’s high quality, we will have them replaced. We do not, however, replace your order should you simply change your mind or make a wrong selection. It is always advised that you physically view the product you have chosen prior to installation.
