BOOK A CONSULTATIONA naturally shaped solid basalt boulder transformed into an understated garden water feature with an organic, spring-like water effect.
At approximately 45cm in diameter and 15cm high, the Miren Boulder has a compact footprint but a more raised, three-dimensional form than our flatter babbling basalt designs.
Water bubbles gently from the top of the stone before travelling across the irregular basalt surface and cascading naturally down the sides. Rather than following a uniform path, the water responds to the individual contours of each natural boulder.
As the basalt becomes wet, its charcoal, black and subtle brown tones deepen considerably, highlighting the natural texture and markings within the stone.
The Boulder replaces the broad polished surface of the classic Miren with a more irregular natural form, creating a water effect that feels closer to a small spring emerging from stone.
At approximately 15cm high, the Boulder sits more prominently above the surrounding pebble area than the flatter Miren stones.
Irregular contours create individual channels and cascades rather than a perfectly uniform flow, giving every Boulder a slightly different water effect.
Compact enough for patios, borders and smaller landscaped spaces while still having the presence and character of genuine solid stone.
The Miren Boulder is designed to look less like a manufactured fountain and more like water naturally emerging from a piece of stone.
Water bubbles from the top before finding its own route across the uneven basalt surface and cascading down the sides towards the concealed reservoir below.
Because every boulder has its own natural shape and contours, the exact flow pattern varies from one stone to another.
Basalt is a dense volcanic stone with naturally occurring variations in colour, markings, form and surface texture.
When dry, the stone displays softer grey and charcoal tones. Once water begins flowing, the basalt becomes considerably darker and richer, revealing natural detail that can be far less noticeable when the stone is dry.
The rugged form also gives water multiple natural channels to follow, ensuring that no two Miren Boulders produce exactly the same pattern.
Every Miren Boulder is formed from genuine natural basalt. Shape, size, colour, markings and surface texture will vary slightly between individual stones, making each feature unique.
The supplied 66cm heavy-duty pebble pool is designed to be buried below ground, leaving only the natural basalt boulder and your chosen decorative finish visible.
Choose a firm, level position with access to a suitable outdoor electrical supply.
Dig a suitable hole for the supplied 66cm pebble pool.
Install the 66cm pebble pool securely and level, with the upper edge slightly above the surrounding soil level to help prevent soil and surface water entering it.
Position the pump inside the pebble pool and connect the water pipe to the pre-drilled basalt boulder.
Position the heavy-duty galvanised steel support grid securely over the pebble pool.
Carefully position the basalt centrally over the supported section of the grid.
Position the supplied white LED light to illuminate the flowing water and wet stone surface.
Cover the visible grid with decorative pebbles while keeping the access hatch available for future pump maintenance.
Fill the pebble pool and switch on the pump. Water bubbles from the top of the boulder, travels naturally across the stone and returns to the hidden reservoir below.
The Miren Babbling Basalt Boulder is supplied as a complete self-contained recirculating water feature system.
Decorative pebbles are available separately, allowing you to completely conceal the 66cm pebble pool and choose a finish that complements your garden.
At approximately 45cm across and 15cm high, the Miren Boulder has a compact footprint while sitting noticeably proud of the surrounding pebble area.
This extra height makes the cascading water easier to see than on a flatter stone while keeping the overall scale suitable for patios, planted borders and smaller landscaped spaces.
Its natural proportions are particularly effective where you want the feature to feel integrated into the garden rather than formal or architectural.
Moving water darkens the basalt and accentuates its natural contours, surface markings and individual texture.
The supplied white LED lighting illuminates the wet stone and flowing water, creating a subtle focal point amongst surrounding planting.
Choose the Boulder if you prefer a more natural, three-dimensional stone with greater height and an organic rock-spring appearance.
Choose the standard Miren if you prefer a broader, lower-profile stone with water spreading across a polished dished surface before cascading over the edges.
