Why is limestone cladding more expensive than thicker blocks?

Questions & Answers
Cladding is comparatively more expensive that thicker blocks because natural limestone is a softer stone, unlike granite or marble it is more difficult to achieve the quality required. This in turn results in a higher wastage rate when cutting the 35mm cladding tiles and also longer production times.

What is limestone cladding?

Questions & Answers
Limestone cladding is cut into 35mm thick tiles from natural limestone, using diamond tipped saw blades. It is available as an all round diamond cut tile for butt jointing or diamond cut face with quarry cut edges for use when mortar joints are to be used.

How is limestone cladding fixed to existing walls?

Questions & Answers
The most common way to fix cladding to a surface is with readily available tile adhesives. Instructions on the tile adhesive should be examined to ensure that it is suitable for the job being undertaken.

Is limestone very expensive for use in housing construction?

Questions & Answers
It is extremely difficult to make a comparison between building construction costs due to the wide range of products available. As a rule of thumb in the Western Australian market, limestone begins at around the top of the range bricks based on the finished 'in the wall' price of a double brick construction.

What is the difference between Quarry cut (tungsten cut) and Diamond cut limestone blocks?

Questions & Answers
When used for housing, the general trend is to use diamond cut Carabooda limestone blocks for a more formal finish, or the more textured biscuit coloured Moore River Limestone blocks to create a character natural stone feel ? it is simply a matter of personal preference. Quarry cut limestone blocks are cut directly from the quarry floor using electric saws with tungsten tipped blades.

What is the mortar mix used when laying limestone blocks?

Questions & Answers
The mortar mix can vary, depending upon the sand used and other factors, however a typical mortar mix in the Perth region is 6 parts good sharp yellow brickies sand, 1 part lime and 1 part of cream (off-white) cement.

What is limestone?

Limestone is a sedimentary rock composed mainly of calcium carbonate (CaCO3), usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.

Where are the blocks made?

Architectural Block, Architectural Masonry Products, Masonry...
NRG Licenses block manufacturers to produce and service a regional area. Licensees distribute the blocks through normal channels, such as dealers and building and masonry contractors. Anchor Concrete Products is the licensed manufacturer of NRG Block in the tri-state area and Philadelphia market.

Is it expensive?

Frequently Asked Questions - Alloy Polishing Co.
Cost is usually relative to the quality of the finished product. All polishing is labor intensive, however, taking the time to do the job properly can take considerable more time than a sloppy job. Keep in mind, the nicer the finish, the more imperfections can appear, a fine sanding scratch, or exceptional buffing lines may not show in a dull finish, yet can be dramatic in a finish with lots of clarity. Extra time is involved in ‘perfecting’ the finish.

How is the cladding attached to the substrate?

Faqs
The tungsten carbide cloth is infiltrated by a brazing alloy, which fuses the carbide particles together and wets the substrate, creating a metallurgical bond.

What is the hardness value of your cladding?

Faqs
Macrohardness is in the 64-70 HRC range for WC 200, 60-66 HRC for WC 210 and 56-62 HRC range for WC219. However, our claddings are a composite of tungsten carbide particles dispersed in a nickel-based alloy matrix. The extremely hard carbide particles, with a Vickers Diamond Pyramid Hardness of about 2000 DPH50g (1865 DPH50g is equivalent to 80 Rockwell C Hardness (HRC)), are surrounded by a two-phase matrix (300-800 DPH50g, equivalent to 30-64 HRC).

Are you capable of polishing the cladding?

Faqs
Yes. Typical ground surfaces are 16-32 R(a). Beyond that, the cladding can be polished to a surface finish of less than 12 R(a) over most of the clad surface.
