BOOK A CONSULTATIONA tall solid granite column combining two contrasting finishes to create two distinct water effects within one architectural feature.
Standing approximately 95cm high and 22cm wide, this Caldera has the presence of a substantial natural stone feature while retaining the slim proportions of the wider column collection.
The smoother grey upper section allows water to glide cleanly over the granite before it reaches the darker chiselled lower section, where the textured surface breaks the flow into smaller ripples and channels.
The result is a water feature that changes visually from top to bottom, combining the refinement of smooth granite with the more rugged character of chiselled stone.
The two-tone treatment gives this Caldera considerably more visual depth than a uniformly finished stone column while retaining a clean overall silhouette.
Contrasting grey and darker granite surfaces divide the column visually without changing its simple architectural shape.
Water travels smoothly across the upper section before the chiselled texture breaks it into more varied movement below.
The tall proportions give the feature enough presence to act as a defining focal point within a larger landscape.
Water is pumped internally to the top of the column and begins by flowing across the smoother grey granite.
This upper surface encourages a cleaner sheet of water with softer reflections and a more refined appearance.
As the flow reaches the darker chiselled section, the irregular stone texture begins to interrupt it, creating smaller streams, ripples and a more broken surface effect.
The upper section has a cleaner, more refined surface that allows water to spread and glide with relatively little interruption, creating a calmer shimmering effect.
The lower section introduces greater surface texture. Water catches against the chiselled stone and separates into smaller channels, creating more pronounced rippling and movement.
At approximately 95cm high and 22cm wide, this Caldera creates considerable vertical presence while remaining relatively narrow at ground level.
The round column shape keeps the overall silhouette simple, allowing the two stone finishes and changing water movement to provide the visual detail.
The Caldera is hand-crafted from solid natural granite, combining a grey speckled upper section with a contrasting darker chiselled finish below.
Granite's subtle natural mineral pattern prevents the smoother section from appearing flat, while the chiselled lower portion adds considerably more physical texture.
When wet, both areas become deeper in tone, making the transition between the two finishes even more pronounced.
Mineral pattern, exact grey and darker tones, surface markings and subtle dimensions can vary between individual pieces. These differences are inherent to genuine natural granite.
The combination of height, contrasting stone and changing water texture makes this version particularly suitable for prominent positions within the garden.
It can provide a vertical counterpoint to low paving and planting, stand at the end of a sight line, or sit alongside contemporary steel elements where the grey granite creates a natural link between stone and metal.
The neutral granite palette also makes it easy to integrate into both modern and more restrained garden schemes.
The feature is supplied with a 60cm diameter pebble pool and steel support grid, allowing the recirculating water system to be concealed beneath the finished surface.
Select a firm, level location with access to a suitable outdoor mains electrical supply.
Prepare the opening required for the supplied 60cm diameter pebble pool.
Install the reservoir securely and ensure it sits level below the finished landscape surface.
Position the supplied mains-powered pump within the reservoir and connect the water feed to the column.
Position the supplied steel support grid securely over the reservoir.
Carefully centre and level the 95cm solid granite feature over the support grid.
Conceal the reservoir and grid with decorative pebbles while maintaining suitable access for servicing.
Fill the reservoir and switch on the pump. Water flows down both granite finishes before continuously returning below.
Decorative pebbles are available separately, allowing the reservoir and steel grid to disappear beneath a finish chosen to complement the granite and surrounding garden.
The smooth grey upper granite and darker chiselled lower section create a clear but relatively restrained two-tone contrast.
Both surfaces deepen in tone. The smooth section develops a stronger sheen while the chiselled stone creates darker shadows, brighter highlights and more broken water movement.
