Different blocks suit different applications, besides the aesthetics, the following factors should be considered – for more exposed areas where a very durable stone is required, more shell is usually suitable. In contrast for internal work or where the stone needs to be finely carved and cleaner, a more shell free stone is often selected.
Other factors that are available bed heights and stone lengths which will often make one Portland quarry more suitable than another. Typically bed heights should not exceed 600mm in height and around 500mm bed heights is often the most economical design, lengths should not exceed 1,000mm and 900mm is an ideal length, although where possible if random lengths with set heights can be specified this can normally result in savings in excess of 10%.
We often have promotions if we build too large a stock in a particular quarry and very competitive discounts can be given which can have a huge impact on reducing the overall cost of the project.
Our large fleet of modern heavy plant, including loading shovels, dumpers and excavators enable us to quarry efficiently keeping waste and cost to a minimum.
