Aqua Moda Caldera / Natural Basalt

Caldera Basalt Polished / Rustic Column Water Feature

A broad natural basalt column combining rugged carved stone with polished detailing to create an organic, constantly changing cascade.

Standing approximately 60cm high and around 30–35cm across, this Caldera has a more substantial, irregular form than the slimmer basalt columns within the collection.

Water bubbles from the top before flowing across a combination of polished, carved and naturally textured basalt. Smoother areas create cleaner movement and reflection, while the more rugged surfaces interrupt the flow into ripples and smaller streams.

Natural charcoal, black and earthy brown colouring becomes richer once wet, while variations in stone shape, texture and colour make every individual feature different.

Why choose the Polished / Rustic Basalt Caldera?

Wider, more irregular and deliberately less formal.

The broad 30–35cm natural stone form gives this Caldera a stronger sense of mass, while the mix of polished and rugged surfaces creates a more varied water effect.

01 / BROAD NATURAL FORM

30–35cm across

A wider natural profile gives the feature more physical presence than the slimmer basalt columns in the range.

02 / CONTRASTING TEXTURES

Polished meets rugged

Smooth and carved surfaces sit alongside more rustic stone, creating visual depth even before the water begins to flow.

03 / NATURAL INDIVIDUALITY

Every piece varies

Natural differences in shape, size, colouring and stone texture ensure each finished water feature has its own character.

The polished / rustic water effect

Water changes character as it moves across the different stone surfaces.

Water rises internally through the basalt and bubbles gently from the top of the feature.

Across smoother polished sections it forms a cleaner, more reflective flow. As it reaches carved and more rugged areas, the uneven surface breaks the cascade into smaller channels, ripples and changing patterns.

The broad natural form means the water can follow different paths around the feature rather than producing a perfectly uniform manufactured cascade.

Top bubbling effect Water emerges gently from the upper surface of the basalt.

Polished flow Smoother sections create cleaner movement and stronger reflections.

Rustic ripple Carved and uneven areas break the flow into more organic movement.

Hidden return Water returns to the concealed reservoir and is continuously reused.

Two contrasting characters

Refined stone and rugged basalt within the same feature.

Polished Basalt

Smoother finished areas expose more of the dark mineral colour and allow water to move in a thinner, more reflective film.

Rustic & Carved Basalt

More irregular sections retain the raw character of natural stone, catching the water and creating stronger texture, shadows and rippling.

Broad natural proportions

A substantial basalt form rather than a perfectly straight column.

At approximately 60cm high, this feature provides useful vertical presence without reaching the height of the tallest Caldera columns.

The real distinction is its 30–35cm natural width. That broader form gives it more visual weight and emphasises the fact that it has been created from an individual piece of basalt.

~60cm Approx. feature height

30–35cm Approx. natural width

66cm Heavy-duty pebble pool diameter

Solid natural basalt

Deep charcoal and brown stone with genuine natural variation.

Basalt naturally displays a mixture of charcoal, black and earthy brown tones, with mineral markings and textures changing from piece to piece.

Polishing and carving selected areas introduces additional contrast without removing the irregular qualities that make the stone distinctive.

Once wet, the darker colours deepen and differences between polished and rugged surfaces become considerably more pronounced.

Natural variation is part of the design

Exact width, shape, colour, markings and surface texture will vary between individual pieces. Dimensions are approximate because the feature is made from genuine natural basalt rather than a moulded material.

A more organic Caldera

Particularly effective where a precise architectural column would feel too formal.

The wider, irregular basalt form works particularly well amongst planting and gravel, where its natural texture can become part of the surrounding landscape.

At around 60cm high it remains visible amongst lower foliage while avoiding the stronger vertical emphasis of a very tall column.

The dark basalt also contrasts strongly with fresh green planting and lighter decorative stone.

Concealed in-ground installation

Hide the water system beneath the landscape.

The feature is supplied with a 66cm diameter heavy-duty pebble pool, allowing the reservoir to be installed beneath the finished garden surface.

Choose the position

Select a firm, level location with suitable access for the water pump.

Excavate

Prepare the opening required for the supplied 66cm diameter heavy-duty reservoir.

Level the reservoir

Position the pebble pool securely and ensure it sits level below the finished surface.

Install the pump

Position the supplied pump within the reservoir and connect the water feed to the basalt.

Prepare the support

Ensure the feature has a firm and stable support above the concealed reservoir.

Position the basalt

Carefully centre and level the natural stone feature over the water system.

Finish the surface

Conceal the reservoir with decorative pebbles while retaining suitable access for future maintenance.

Fill & enjoy

Fill the reservoir and start the pump. Water bubbles from the top before cascading across the polished and rustic basalt.

No permanent water supply required The Caldera is a self-contained recirculating water feature, so no permanent plumbing connection is required. The supplied pump includes a 10m cable. Periodically top up the reservoir to replace water lost naturally through evaporation and splash.

Complete water feature kit

Supplied with the main components required for installation.

Polished / Rustic Basalt Feature Natural basalt measuring approximately 60cm high and 30–35cm wide, with carved, polished and rustic detailing.

66cm Heavy-Duty Pebble Pool Concealed underground reservoir for the self-contained recirculating water system.

Suitable Water Pump Recirculating pump matched to the feature and supplied with a 10m cable.

Self-Contained System Water continuously circulates between the hidden reservoir and the natural basalt feature.

Decorative pebbles are available separately, allowing the reservoir to be concealed beneath a finish chosen to complement the basalt and surrounding landscape.

Basalt transformed by water

Water deepens the colour and exaggerates every change in texture.

When dry

The stone displays softer charcoal, black and brown tones, with polished surfaces contrasting against the more rugged carved and natural areas.

When wet

The basalt darkens considerably. Polished sections develop a deeper sheen while rugged areas create stronger shadows, highlights and visibly more broken water movement.
