- + Genuine Natural Stone

At Allstone we stock only genuine, natural stone which has been collected directly from the earth’s crust and processed to the finished product.  The natural stones we stock include sandstone, bluestone, travertine, granite, limestone, marble, slate, basalt, porphyry, ironstone and quartzite. 

- + Grouting & Pointing

Tile Grouting
We generally recommend a minimum grout gap of 3mm.
Please check with us for narrower gaps.
Generally we recommend that the whole stone is covered with the grout and then removed. (Basalt in particular has micro holes which need to be filled evenly.)

Traditional Stonework
Pointing Mixes
Flush/Slightly Recessed Pointing - Brick style pointing.
Scribed Line Pointing - Mortar is smeared over the edgs of the stone and  a line is scribed into the mortar. The aim is to blur the edge of the stone.
Fine Line Pointing -  As above but with the scribed line painted.
Raked joints - where the mortar is taken out to a depth of approx. 1-2cm. This is mainly used on solid uncut blocks such as Bluestone.

- + Installing Blocks

We recommend blocks be installed by a qualified Stonemason.
Use a standard brickies mortar.

For random ashlar pattern the stone is cut to fit standard brick work with the stones 1, 2 & 3 bricks heights and 1, 1.5, 2 & 2.5 bricks long. The spacing is 10mm - the same as brickwork.


- + Installing Pavers

Good results are always based on good preparation - time spent ensuring levels are correct to ensure adequate run-off and that the base is correctly compacted will save heartache later on.

There are three main methods for installing pavers:
1) Glued to a concrete base - The Rolls Royce method and worth the additional investment for premium results. Use the 'Tarver' method to glue the pavers (see 'Installing Tiles and Veneers'). Pavers are grouted after being stuck down (ensure grout is pushed all the way into joint).
No movement, weeds or ants with this method.
Note: Ensure concrete is fully cured prior to laying.
2) Laid in mortar - pavers are bedded into a minimum 40-50mm layer of mortar on top of a compacted base. The mortar mix and possibly the back of the paver will require a product like 'bondcrete' to be used to ensure adhesion.
A premium result for pedestrian paving. No movement, weeds or ants with this method. Grouting as above.
3) In sand on a compacted base - this is the cheapest method of installation and is better for smaller format pavers. 30mm Pavers are laid on a  layer of approx. 30mm of washed, salt free sand over a compacted base. Paving sand or 'Pavelock' is used for jointing.
With large format pavers there may be gaps left under the stone causing weak points that may crack. Not suitable for less than 30mm thick pavers.

We recommend the use of a layer of plastic on top of the compacted base to prevent moisture affecting the paving.
Granite Cobblestones are generally glued to a concrete base or laid in mortar and then grouted with a mortar mix in the correct colour.
Do not let glue, grout or mortar dry on the stone. Sponge clean and rinse with clean water.

- + Installing Tiles and Veneers

Tiles and Veneers are thin stones (generally 10 - 20mm thick) fixed to walls or floors with the appropriate adhesive.

Brick masonry is best (except hard burnt and glazed).
Brick on edge is not suitable for unpointed stone (e.g Ledgestone) as light and moisture can penetrate the wall.
Stonesheet - James Hardie 8.5mm EasyLap ( and BGC’s 9mm Stonesheet ( are the only compressed cement sheeting we know to be rated to handle the weight of stone veneer. The main issue when adhering to cement sheet is the contact between the glue and the board.

Tiltup - walls must be mechanically abraded to remove all releasing agent.

NOTE: - Blueboard is not suitable for stone veneers.
Hebel has weight limitations but may be suitable for lighter, thinner veneers under 32kg/sm.

Concrete is best.

Adhesive - Master Grip Lite is a superior polymer adhesive for all substrates
Primer - Master Primer assists in bonding adhesive to the substrate and is recommended for all substrates.

Stone should be fixed according to the Australian Standard using the Tarver Method to adhere stone to the substrate:
"Spread the adhesive on the surface to achieve the best possible mechanical bond. 'Rib' the adhesive with a notched 10mm trowel to obtain a uniform thickness. When the trowel is held at an appropriate angle and its notched side is drawn over the adhesive, it will give a series of parallel ribs. The tiles should be pressed into and moved at least the width of a rib perpendicular to the adhesive ribs. This should achieve both the minimum required coverage and bed thickness. This operation has to be carried out correctly as adequate ribs are essential to ensure an evenly distributed area of contact between tile and adhesive."
These ribs should be horizontal for walls.
For larger and uneven tiles we recomend that the back of the stone is buttered with adhesive. This involves keying the adhesive into the back of the stone in a thin layer.
Clean back of stone of dirt/dust with a moist sponge if required.
There can be some bleeding of moisture on dark coloured tiles, the use of the above adhesives and method should minimise this. Stone may also be presealed.
For substrates other than brick masonry extra care must be taken.
While stone is cut to exacting tolerances we recommend a minimum joint of 3mm.
For random ashlar pattern a 10mm joint must be used.
For heights over 3m it is recommended that  additional stainless steel brackets are used.
It is essential to keep stone clean and not let glue, grout or mortar dry on the stone. Sponge clean and rinse with clean water.
DO NOT USE ACID ON STONE - it can damage the stone.

- + Packaging, Delivery & Storage

- + Protecting Pool Surrounds

Choosing stone for your pool surrounds is more than thinking about the aesthetic appeal, it requires consideration of the stone’s qualities and the protection needed to make it resilient against a range of factors more than water, salt and chlorine.

Pool areas are often high use spaces affected by organic materials, body oils and stains from food and beverages so ensuring that the stone is sealed is an important step towards preserving the integrity of the stone and limiting soiling. However, sealers cannot provide total stain proofing, they offer protection against the contaminant piercing the surface so allowing time to remove an offending stain.  Some particularly strong stains cannot be removed.

Regardless of the sealer treatment selected the life of a sealer’s effectiveness will depend upon the physical characteristics of the stone, so it is important to get professional advice regarding the stone’s characteristics and suitability for an area.

Stone can be affected by pool water. The porous nature of many stones means that water with its dissolved salts can cause damage as it absorbs into the stone. The subsequent crystallisation may lead to it breaking up the stone or leaving an efflorescent effect on the surface.

There are several options to consider in selecting a treatment:

  • Silicone – provides a strong and durable management when combined with stone strengthening technology
  • Fluorochemical – works well to preserve the surface from some stains but only provides some level of water repellence
  • Penetrating sealing – offers protection against oily stains and is water repellent.

- + Sizes & Patterns

Stone comes in a variety of sizes and patterns dependant on the look to be achieved.

Adelaide stonemasons have traditionally used random ashlar pattern in their work.
Random ashlar uses the mix of sizes below in a random pattern without continuous joints.

Random coursed ashlar uses the same mix of stones as above but laid in courses (horizontal lines) with the heights mixed up.
Coursed ashlar pattern uses different lengths all at the same height.
Banding involves introducing a band of narrow stones every 2nd or 3rd course to break the coursed pattern. 
Stretcher or brick bond is the offset pattern that normal bricks are laid in.
Stack bond is how a lot of more modern tiles are laid - stacked on top of each other

- + Sustainable Stone

Natural stone is not only attractive, it offers positive environmental qualities – long life-cycle, strength, ease of care and maintenance, recyclability and opportunities for quarrying and manufacturing best practices.  When you choose natural stone, you contribute towards green building by aiming to preserve, restore and improve the natural environment.

At Allstone we support quarries that use environmentally friendly processes and that are ethical in their work practices.

- + Disclaimer

All natural stones are products of nature and as such no two pieces are exactly alike. Colour variations will occur both initially and over time. We recommend inspecting the material prior to installation to check the colour, veining, sizing, finish and prepare and blend as required to meet owner / buyer approval. The purchaser acknowledges that additional stone ordered at a later date may not be available, can be more costly and cannot be guaranteed to match the original stone. Free quotations are estimates calculated on areas and include cutting and wastage. Wall measurements include 10mm pointing in length and widths. No responsibility is taken for any mistakes in estimations. All measurements are nominal sizes only, variations may occur as a consequence of quarrying and cutting. Appropriate measures should be taken when laying pavers to prevent ingress of salt from subsoil, especially around pools (e.g. use of Forticon & sealers). When using adhesives to install stone the "Tarver" method must be used. No claims will be accepted after material is installed. At Allstone we recommend that all stone be sealed with the appropriate DryTreat sealer by a licensed applicator. When labour is included, the builder (or owner) is responsible for waste management on site to conform to EPA standards.
