The latest design in the white, marble-veined Musa Collection of sintered stone from Lapitec, sold in the UK by The Marble & Granite Centre in Rickmansworth, Hertfordshire, is Bianco Giulia, available in book-matched, large format slabs.

Unlike the porcelains with which Lapitec is often compared, the pattern is not printed on – it is full-bodied, so the slabs can be machined across their full thickness while maintaining a consistent appearance and performance.

The Bianco Assoluto-effect Musa Collection was launched in 2019. It is available in Lux, Satin and Lithos finishes with different levels of marbling. The latest addition of Bianco Giulia is pictured above.

The marble-effects were the first Lapitec products to be free of crystalline silica, but this year Lapitec has been pushing the message that all Lapitec products are now completely free of crystalline silica, so there is no danger of processing the slabs leading to respirable crystalline silica (RCS) in the air.

Inhalation of dust containing RCS, which is naturally present in clay, granite, quartz, sandstone, slate, concrete and other minerals and materials, can cause silicosis and other chronic respiratory diseases that can lead to premature death.

Lapitec says the removal of crystalline silica is in response to new, stricter health regulations, especially in the United States and Australia, and that it has been made possible by the development of a patented mineral formula it calls Biorite, which is a registered trademark.

Biorite is patented – one of more than 25 patents involved in the production of Lapitec, for which the brand thanks the advanced technologies of its parent company, Breton SpA, famous for its stone processing machinery and inventor of the original equipment used to make engineered quartz.

With Lapitec, it decided to keep the process to itself and control production.

As well as being free of crystalline silica, Lapitec is also free of any petroleum derivatives, such as resins and digital printing inks.

Marcello Toncelli, who heads Lapitec, says of the removal of crystalline silica: “We have been experimenting for a long time, and have invested significant resources over the past decade to achieve this outstanding result, which we are very proud of.

“Using natural minerals, we have found a way to synthesise a new mineral that we have called Biorite, a Lapitec exclusive that, together with the other components of the mixture, makes the material completely silica-free and safe for fabricators, installers and anyone mechanically processing the material, starting with our own workers.”

Some have said sintered stone is simply another name for porcelain, but Marcello maintains that the advances made with Lapitec make it a unique material, ideal for use indoors and out. And Lapitec is being used widely in the world for façades, floors, swimming pools, kitchens, bathrooms, decor and more.

And, adds Marcello: “The ability to create certain raw materials [in-house] also makes us more autonomous, allowing the company to respond to the current shortage of raw materials that is paralysing the global market.”

The Marble & Granite Centre says the demand for classic-veined white marble such as Carrara and Statuario, reflected in the Lapitec marble-look products, continues, but that there is also a big increase in demand for more dramatic natural stones – so much so, in fact, that it has just moved 5,000m2 of stone in order to install a new covered storage facility in order to be able to stock more of the luxury marbles and quartzites.

The Kopron cover's open sides still allow plenty of natural light into the area for ideal viewing of the materials.

The Marble & Granite Centre says it is seeing seeing many more interior designers being braver with colour and experimenting with more striking materials, creating increased interest in natural stones such as granites and quartzites, which are more colourful, as well as brighter marbles such as the purple and green Calacatta Viola Monet.

The latest quartzite arrivals at The Marble & Granite Centre include the Brazilian Blue Mare, Explosion Blue, and Patagonia, and from Iran, Vancouver.

During the pandemic more people have taken to cycling and walking and, in response, the government has fast-tracked statutory guidance to local authorities saying they should reallocate road space to these activities. The aim is to provide a safer way for all age groups to use healthier methods of transportation.

Hardscape has made its own rapid response to the move and introduced a range of what it calls ‘Inclusive Infrastructure Solutions’ – kerbs designed to create environments that integrate cyclists, pedestrians and vehicles safely.

The new range continues Hardscape’s tradition of introducing inspirational, innovative products from around the globe, giving landscape architects and specifiers quality and function in a range of natural and man-made materials.

The range includes kerbs with various slopes, end styles, widths, depths, gradients, and radii, in natural stone (granite), concrete, and Kellen Lavaro (concrete that has exposed stones in its surface).

The future of inclusive infrastructure solutions

Hardscape says the extensive research, detailed specification, and implementation of its new range of Inclusive Infrastructure Solutions reflects the company’s DNA, with its commitment to environmental, social, and corporate governance (ESG).

It sees these products as the natural next step in external space design, engineering and planning, creating an urban environment that all users can share equitably and safely.

Paving the way with Dutch-inspired policy and design

During the past half-century the Dutch have mastered the art of creating an environment that safely integrates cyclists, pedestrians and vehicles. And one of the strategies used is logical, coherent kerb systems for actively segregating each group.

Hardscape has worked with Dutch suppliers for more than 20 years, and is now using its knowledge and distribution networks to bring this innovative new product range of kerbs to the UK.

There are options for just about every conceivable project, offering optimum design for attractive infrastructure spaces that are accessible for all.

“We are introducing these products to the UK with the support and impetus of the UK government’s wellbeing principles and directives,” says Hardscape MD Mathew Haslam. “We hope to inspire the next generation of connected towns and cities that are brave in specification and designed to bring a long-lasting benefit for us all.”

The natural granite products use an inherently low carbon natural material, but the concrete products also have a reduced carbon content thanks to the use of Cero geopolymer, which claims to cut the carbon impact by up to 50% compared with cement.

Sentencing of two companies involved in bridge repairs that led to the drowning of two stonemasons will take place in October, Limerick Circuit Court in Ireland decided this week (27 July).

The men drowned when a steel cable holding the cage they were working in snapped and the cage fell into the River Shannon. They had been working on Thomond Bridge at Limerick City.

The men were wearing life jackets but were connected to the cage by harnesses and could not free themselves. They were said to have been just 60cm under water. A third man did manage to get free of the harness and was rescued from the river.

The incident happened in 2015 (read the report at the time here).

The men who died were Bryan Whelan (29) from Co Clare and TJ O’Herlihy (36) from Co Kerry. Relatives of the deceased left the court in tears as the court saw a video of the moment the steel cage fell into the river.

Separate investigations by the Gardai (police) and the Health & Safety Authortiy (HSA) followed the incident and, as a result, criminal charges were brought against two companies: Nationwide Crane Hire Ltd of Dock Road, Limerick, and Palfinger Ireland Ltd of Church Hill, Cloncollog, Tullamore, Co Offaly.

The investigations found that a crane was mounted on a flat-bed lorry on the bridge with an extendable telescopic winch that held the cage by a wire cable. A safety mechanism preventing weight overloading on the crane had failed, resulting in “unbearable stress” on the wire cable holding the cage. The cable snapped and the cage fell into the river with the three men harnessed to it.

The two companies were in court this week (27 July). Both pleaded guilty to breaches of the Health & Safety at Work Act.

Palfinger had supplied the winch crane involved in the incident to Nationwide in 2003, but the court heard that the crane’s user manual was missing a chapter on the importance of frequent testing of the crane’s overload protection system, which it emerged had failed on the day of the tragedy.

Palfinger pleaded guilty to having failed to take steps to ensure Nationwide was provided with adequate information about the crane and its operation to ensure it would be safe in use.

Nationwide pleaded guilty to failing to ensure people employed by it were not exposed to risks to their safety, health and welfare.

Dermot O’Brien, lead investigator from HSA, said the two defendant companies had co-operated fully with the Authority’s probe and he hoped the information gathered would prevent similar tragedies.

Judge Tom O’Donnell said it would be inappropriate to deliver an immediate judgment after hearing a significant amount of evidence and “deeply poignant” victim impact statements. He adjourned sentencing to 7 October.

Police are appealing for help in finding the thieves who took stone from a National Trust property in Derbyshire.

According to the Derbyshire Times website, the stone was taken from a property just off Snake Pass and would have required a van to move. It included about 3m² of stone paving slabs and the seat from a stone bench.

This might have been stolen for a specific project and police ask anyone who has had, or knows of someone who has had, about 3m² of aged natural stone paving or coping installed to phone Derbyshire Constabulary on 101 and ask to speak to the Rural Crime Team.

Marshalls PLC has been actively working to improve human rights in global supply chains for almost two decades. To strengthen its work in this area, the hard landscaping materials supplier has appointed Emma Crates as Group Business & Human Rights Manager and Nasriah Jamaludin as Business and Human Rights Executive.

The long-awaited part 5 of BS 8298: Code of Practice for the Design & Installation of Natural Stone Cladding & Lining, has finally been produced and is out for public comment.

Part 5 covers interiors. It was intended to be produced for the 2010 revision that split the standard into supposedly five parts. The first four parts, covering the design and installation of stone cladding, were generally welcomed as they facilitated the use of thinner stone.

A revised version of the standard was published at the start of this year and reduced the standard for exterior cladding to three parts, with the first part of general principals being incorporated into the remaining three parts. There was still no Part 5 for interiors but there was a promise once again that it would follow.

This time it has. You can see it and comment on it on the British Standards Institution (BSI) website here. You have until 27 September to make your comments.

Part 5 covers the selection of stone, its testing requirements, the typical fixing details and the influence of loadings and impact on the stone’s thickness.

Portland stone company Albion Stone has summarised the standard on its website using the BSI data and welcomes the new Part 5 not least because it includes a worked example showing that Jordans Whitbed at 900mm x 600mm can be used at 30mm thick. www.albionstone.com
