Grandiosa - Ercolano – Natural
Ercolano Product Story
With four on-trend colours, Grandiosa is an avant-garde stone-effect tile that combines beauty with grandeur. The range comes in three distinct finishes, Natural, Honed and Polished, with each offering a particular style of its own. This enables Grandiosa to adapt to the requirements of the scheme, providing designers with the opportunity to create remarkably diverse spaces. For projects requiring something a little bit special, we have introduced a range of accompanying bookmatched pieces. These highly polished decorative pairs feature a perfect mirror image pattern, creating a show-stopping bookmatched effect. Whatever the occasion, Grandiosa is sure to make a dramatic impact. Ercolano is part of our Stone-effect Collection.

Bookmatched
Grandiosa features remarkable 1200 x 1200 mm Bookmatched tiles, ideal for creating a breathtaking feature wall. Tiles are available in ‘Block A’ and ‘Block B’ matching stone surfaces, the pattern of which mirror each other. Using both blocks in various configurations enables the creation of up to three bookmatched designs. The three bookmatched designs shown here require four tiles (Two x ‘Block A’ and Two x ‘Block B’). Grandiosa Bookmatched tiles are available in all four colourways.

Technical Specification
Shade Tone Variance
Grandiosa has been classified:
Understanding Shade Tone Variance
Shade, texture and tone can vary from piece to piece within a single tile production run. V1 shade tone variation has little or no change from piece to piece where a V4 might have a substantial variety of shade, texture and tone variation.
| Variance Rating | Description |
|---|---|
| V1 | Uniform Appearance |
| V2 | Slight Variation |
| V3 | Moderate Variation |
| V4 | Substantial Variation |
Pendulum Test Values (BS 7976-2)
| Finish | Conditions | Result | Slip Potential |
|---|---|---|---|
| Natural | Dry | 60 | |
| Natural | Wet | 30 |
Understanding Pendulum Data
The HSE Approved Pendulum Test accurately replicates the Dynamical Coefficient of Friction (COF) or 'Heel Slip' on floor surfaces and is designed to replicate a pedestrian heel strike, the point at which most slips occur.
The pendulum test readings obtained are referred to as either the Slip Resistance Value (SRV) or Pendulum Test Value (PTV). When the test is operated properly, the PTV should be interpreted as shown in the table below. This table relates to pedestrians walking in a straight line on a level surface. It can be used to accurately test the slip potential on dry or contaminated floors.
| PTV | Slip Potential |
|---|---|
| 0 - 24 | High |
| 25 - 35 | Moderate |
| 36 + | Low |
See British Standard BS 7976-2 for more information on conducting Floor Pendulum Testing on pedestrian surfaces. Pendulum Test Certificate available on request.
Ramp Test Values (DIN 51130)
| Finish/Style | R Rating Value | Friction |
|---|---|---|
| slip rating | R10 |
Understanding Ramp Test Data
DIN Standard Ramp Testing (DIN 51130) is an alternative to Pendulum Testing and generally categorised as an 'off-site' activity because of the size and complexity of the equipment required to carry out the test. The Slip Resistance Values (RSV) are factory gate values (based on supplied tiles) and categorised using the Ramp Test (DIN 51130) method which is commonly used by European factories. In this method, a lubricated inclined platform is adjusted to a gradually increasing gradient, and the angle is measured at which a person walking on it slips.
We have deliberately not included the ramp test angles on this page as this information can be confused with the angle that a floor may be safely set to, which is incorrect. The shod test results are quoted as an R Rating value from R9 to R13, which relates to the ramp angle.
| R Rating Value | Friction |
|---|---|
| R9 | Minimal |
| R10 | Normal |
| R11 | Good |
| R12 | Good |
| R13 | Very high |
See the Health and Safety Executives website for more information regarding the Ramp Test procedure. Ramp Test Certificate available on request.
