Stone & Marble Slip Testing

At Slip Testing, we offer comprehensive slip resistance testing for natural stone and polished marble flooring across commercial, residential, and public environments and throughout the UK. From luxury hotel lobbies and office foyers to retail stores and heritage buildings, we ensure that hard-surface floors remain compliant, attractive, and safe for everyday use.

Using precision Pendulum Test equipment approved by the HSE, we measure the slip resistance of stone, marble, and similar materials in both wet and dry conditions — helping you maintain high safety standards without compromising on aesthetics.

How Much Does Stone & Marble Slip Testing Cost?

The cost of stone and marble slip testing starts from around £295 per test area, depending on the number of surfaces tested, site layout, and whether testing is required in both wet and dry conditions.

Pricing is affected by floor size, access considerations, and the type of material being assessed — such as polished marble, limestone, granite, or travertine. Discounts are available for multiple test zones or ongoing maintenance contracts.

Where Should Stone & Marble Slip Testing Be Carried Out?

Stone and marble slip testing should be performed in any location where smooth or polished surfaces are used, including:

• Hotel and office entrances – High-traffic zones where rainwater and debris can reduce grip.

• Lobby and reception floors – Polished marble or granite areas that become slick when damp.

• Retail and showroom spaces – Decorative stone floors subject to cleaning products and customer movement.

• Bathroom and spa areas – Wet environments requiring tested slip resistance for guest safety.

• Restaurant and bar areas – Transitional spaces between dry and spill-prone surfaces.

• Outdoor terraces and steps – Stone surfaces exposed to weather and surface wear.

What Testing Standards Are Applied to Stone & Marble Floors?

All stone and marble slip testing is conducted following BS 7976-2 and UKSRG standards using the HSE-endorsed Pendulum Test method.

The Pendulum Test Value (PTV) measures how slippery a floor is under specific conditions, providing an objective risk rating. A PTV of 36 or above is typically regarded as low slip potential in wet environments. Our detailed reports include photographs, results, and recommendations for improving floor safety and compliance.

How Does Stone & Marble Slip Testing Assess Real-World Performance?

Our stone and marble slip testing evaluates how your floors perform under both wet and dry conditions to simulate actual usage.

Natural and polished stone surfaces may appear safe when dry, but often become slippery when exposed to cleaning agents, water, or foot traffic. Testing both conditions gives a complete overview of performance, helping to identify problem areas before they lead to incidents.

How Quickly Can Stone & Marble Slip Testing Be Conducted?

Stone and marble slip testing can usually be scheduled within 48 to 72 hours, with urgent testing available for immediate safety or compliance requirements.

We provide flexible scheduling, including early mornings, late evenings, and weekends, to minimise disruption for businesses, hotels, or public buildings operating around the clock.

What Slip Ratings Are Recommended for Stone & Marble Surfaces?

The minimum recommended Pendulum Test Value (PTV) for stone and marble floors in wet conditions is 36.

Highly polished finishes, such as marble or granite, may require additional treatments or maintenance to achieve and maintain this level. Our testing helps identify surfaces that fall below compliance and guides suitable corrective measures.

Can Stone & Marble Slip Testing Include Maintenance and Cleaning Reviews?

Our stone and marble slip testing services can be paired with a surface maintenance audit to evaluate how cleaning products, sealants, and polishes affect slip performance.

In many cases, residues or wax coatings can increase slipperiness, which our integrated service identifies and provides solutions for long-term surface safety.

What Types of Properties Benefit From Stone & Marble Slip Testing?

Stone and marble slip testing is widely used in hotels, museums, retail stores, shopping centres, office buildings, leisure facilities, and luxury residential developments.

These environments feature elegant, hard-surface floors that must balance aesthetic appeal with functional safety. Routine slip testing ensures compliance, reduces liability risks, and protects staff, visitors, and guests alike.
