Design and specification advice
Pendulum Test
The Pendulum test measures the dynamic coefficient of friction (CoF), replicating the crucial heel strike of a pedestrian, a key moment when slips are most likely to occur. For more details, please refer to our informative advice sheet.
Shod Slip: Pendulum Slider 96
Where it is known that slippery conditions might arise in service and present a significant hazard, tiles with slip resistant finishes suitable for the conditions and location should be used. Flooring materials should not be highly slippery when used in locations that suffer occasional wetting, which increases surface slipperiness, i.e. shopping malls or office receptions.
Barefoot Slip: Pendulum Slider 55
As the wet room would be classed as an area of continuous contamination (by water) during the time of use, there should be a minimum PTV of 36 on the level surface, however, as the shower zone is sloped by 2%, this figure should be increased to a minimum of PTV of 38.

External Areas: Pendulum Slider 96
External situations have extra risk of different types of contaminants likely to be present on the floor. Cleaning procedures should be carried out regularly.
Shade Variation
Shade variation is a natural characteristic of all tile products, including natural stone, porcelain, glass, and ceramic. Both shade and texture can vary significantly from tile to tile, even within the same production batch.
LRV (Light reflectance values)
In architecture, the Light Reflectance Value (LRV) is a metric that indicates the percentage of visible and usable light a surface reflects when illuminated by a light source. For more information, please consult our comprehensive advice sheet.
PEI Ratings
PEI ratings indicate the wear resistance of glazed vitreous and porcelain stoneware tiles, in accordance with the standards set by EN ISO 10545-7. For more information, please refer to our advice sheet.
Surface Roughness Measurement
Surface microroughness is an indication of slipperiness in water-contaminated conditions may be simply obtained by measuring the surface roughness of flooring materials.

Installation Advice
Stair nosing
Specifiers should keep five key aspects in mind when considering stair nosings. These nosings create a ‘ladder effect’ on the stairway, visible from both the top and the bottom. For more information, please refer to our advice sheet.
Fixing Specification
Grestec offer complimentary fixing specification advice for every project senario. For more information, please refer to our advice sheet.
Movement Joints
Movement joints should be a minimum of 6mm. For more information, please refer to our advice sheet.
Raised external terrace system
Raised outdoor floors exploits the conventional system of floating or raised floors. With this laying system, all the pipes and wiring systems are laid beneath the tiled surface and can be inspected at any time. It offers instant accessibility, by allowing the lifting and removal of the slabs. For more information, please refer to our advice sheet.
Grout and adhesives
Fugabella grout and adhesives. For more information, please refer to our advice sheet.

VOC (Volatile Organic Compound)
Ceramic tiles are classified as non VOC emitting products by type, this is universally accepted by all the assessment methods.
