Marshalls will be exhibiting at this year’s RHS Chelsea Flower Show from 19th-23rd May at Stand EA60.

The company also paves the way in the Fresh garden area with its brand new SYMPHONY Vitrified paving, as well as stunning natural stone for the walkways.

Marshalls’ paving covers 400m² in total, with SYMPHONY Vitrified paving in Blue covering 261m² and its Sawn Versuro King Size sandstone in Autumn Bronze covering 141m².

Vitrified paving is perfect for inside-outside living, offering high levels of durability and low water absorbency, combined with stunning good looks.

Visit Marshalls’ trade stand for more information on this exciting new product and to find out more about Marshalls' new Stone Standard, its accredited contractor scheme and new product innovation.

Here’s what Marshalls will be discussing at their trade stand:

- Did you know that 50% of Indian sandstone paving currently available on the British market is not fit for purpose?

Marshalls has undertaken extensive testing of a range of Indian Sandstone paving available on the market today and has discovered that 50% do not meet the British Standard.

Sandstones can appear the same when displayed at a merchant or in a brochure, but they do have different properties and can perform very differently when installed. Laboratory testing gives you a full picture of the technical quality of stone.

There are three key factors that must be considered when purchasing stone to be installed as paving in the UK and these are, water absorbency, flexural strength and frost resistance.

A stone with high water absorbency will not only turn green, (a common consumer complaint with sandstone patios) but may also be more susceptible to frost action which will degrade the stone.

In terms of flexural strength, a stone with poor strength means that the product could be easily damaged in transit, during the installation process, or simply by everyday use.

It’s also important to consider frost resistance. A stone that loses strength when subjected to repeated frosts is far more likely to fail.

There is a British Standard that covers these issues. The design and installation standard BS7533 part 12 covers the technical performance of stone, for example it provides guidance regarding the maximum water absorbency for product supplied to class 2 is 2.5%.

To ensure you select stone which is technically up to standard, Marshalls advises using a supplier that tests all its products and can supply you with an in-date test certificate, or declaration of performance.

If a supplier is unable to supply these details there’s no guarantee that their stone is technically sound.

At Marshalls we’ve tested all our stone to be 100% sure that every single one meets or exceeds the British Standard, we’ve called this The Stone Standard.

For more information on The Stone Standard please visit our stand and speak to one of our stone experts.
