Artificial stone For Garden S-05

Gardens and outdoor spaces contain wide functional elements at ground level: large manhole covers, broad drain lids, tree stumps, wide valve manifolds, pool equipment bases, and multi-pipe clusters. These objects are too wide for standard compact covers — the S-01 at ø 39 cm, the S-04 at ø 33 cm — but don’t require the height or bulk of M-series stones.

The mismatch between cover size and target width creates a practical problem: either the cover is too small and leaves the utility partially exposed, or the homeowner must jump to the larger, more expensive M-series when a flat S-series profile would look more natural.

Traditional alternatives are limited. A natural flat boulder of comparable size weighs 80–200 kg, requires mechanical handling, and cannot be hollowed to provide equipment access. Budget plastic covers in this size range are lightweight but structurally weak — painted surfaces fade, thin walls crack, and the flat form tends to warp after thermal cycling.

The S-05 resolves this gap by providing a wide, low-profile stone with 49 cm interior coverage diameter and just 23 cm height — covering the widest ground area in the S-series without visual excess in height. The broad horizontal fieldstone form makes the S-05 particularly effective on open lawns, gravel areas, and natural garden zones — where a wide flat stone looks like a natural part of the landscape.

The S-05 is a hollow shell with a wide, flat fieldstone profile — a broad, low-profile form with a gently undulating top surface and irregular natural edges. The height is consistently low at approximately 23 cm across the profile. The interior provides a usable coverage diameter of ~49 cm.

Installation is immediate. Place the stone directly over the target object on any surface. No anchoring, no foundation, no tools. Total setup time: under one minute. To access the equipment underneath, lift the stone with both hands and set it aside.

Stability comes from the stone’s own weight (9 kg) and its exceptionally broad base footprint (~66 × 51 cm — the widest in the S-series). The large ground contact area provides excellent wind stability, making the S-05 one of the most secure models in the range even in exposed positions.

Seasonal behavior is neutral. The fiberglass composite structure does not absorb water, does not expand or contract meaningfully with temperature changes, and tolerates a continuous operating range from −30 °C to +60 °C. The stone performs identically in summer heat, autumn rain, and winter frost. It does not need to be removed, covered, or stored during any season.

Base contact — the stone has a non-sealed base and rests directly on the ground surface. It is not hermetically sealed; natural micro air exchange between the interior cavity and the surrounding environment is possible through the ground contact zone.

Safety and load limitations — the product supports 100+ kg of static load under normal conditions. It is not a load-bearing structure, is not designed for impact loads, and is not intended for jumping or active play without prior structural adaptation of the product. Use in children’s and public zones is possible with a pre-agreed usage scenario, engineering adaptation of the structure, and coordination of safety requirements.

The S-05 is constructed from a multi-layer fiberglass composite — the same class of material used in boat hull construction, chosen for its strength-to-weight ratio and long-term weather resistance.

The outer surface is a marble chip and marble powder gelcoat of the ISO/NPG class. The color is not painted, printed, or applied as a film. Instead, natural stone chips and stone dust of different colors are mixed directly into the gelcoat compound during manufacturing. This means the color and grain are embedded in the material itself, producing a surface that ages gracefully rather than peeling, flaking, or fading.

Compared with typical alternatives:

The S-05 occupies a deliberate position: wider coverage than any other S-series model, lighter than any natural alternative of comparable size, and built from engineering-grade composite that outlasts budget plastic by a factor of three or more.

Maintenance is minimal. Clean occasionally with water and a soft brush. No sealing, repainting, or chemical treatment is ever required.

Concealing a large round manhole cover or inspection lid (ø 40–49 cm)

The S-05’s ø 49 cm coverage fits large EU residential manhole covers and heavy-duty inspection lids that are too wide for any other S-series model. The low 23 cm profile keeps the stone grounded and proportional over flat utility covers.

Covering a wide drain lid or drainage inspection point

Broad drain covers on terraces, driveways, and lawns fit within the S-05’s wide footprint. The flat fieldstone form sits naturally flush with the surrounding surface.

Hiding a tree stump (up to ø 49 cm) at or near ground level

Cut stumps up to ø 49 cm can be concealed entirely — eliminating the visual and physical disruption of exposed stumps without the cost and effort of stump removal. The wide flat profile rests naturally over the stump area.

Concealing a pool pump base or wide filtration equipment housing

Horizontal footprints of sand-filter bases and recirculation pumps with wide housings fit within the S-05’s 49 cm coverage. The non-sealed base allows natural micro air exchange.

Covering a multi-valve irrigation assembly or wide sprinkler control box

Landscape irrigation control units with large rectangular bases fit within the S-05’s wide interior. The stone protects the assembly from weather and accidental damage while maintaining access.

Hiding a ground-level utility meter box (gas, water, electric)

Flat meter lids in lawns and paved areas — too wide for compact S-models — fit within the S-05’s ø 49 cm coverage, replacing an industrial element with a natural fieldstone.

Concealing a septic or drainage inspection cover (ø 38–49 cm)

Standard EU septic and drainage inspection covers fit within the S-05’s coverage range. The broad flat form integrates naturally into lawn and gravel surfaces.

Covering a cluster of pipes or fittings exiting the ground

When multiple pipes or fittings exit the ground in close proximity, the S-05’s wide coverage can conceal the entire cluster under a single natural-looking fieldstone.

The S-05 is the maximum-width model of the GARTENDEK S-series — the widest coverage diameter (ø 49 cm) with a broad, flat fieldstone silhouette that blends naturally into open lawns, gravel beds, and natural garden zones.

At €254.20 including delivery, it is positioned in the premium tier alongside S-03 (€254.88) — justified by the maximum coverage area that no other S-series model can match. The wide base footprint (66 × 51 cm) is the largest in the S-series.

Choose the S-05 when:

• The object to conceal is wide (up to ø 49 cm) but not tall (up to 23 cm)
• Maximum horizontal coverage is needed without vertical dominance
• The target is a large manhole cover, wide drain lid, tree stump, or pool equipment base
• A broad, grounded fieldstone accent suits the garden zone

Consider a different model when:

• The target is smaller than ø 39 cm — S-01 (ø 39 cm) or S-04 (ø 33 cm) provide a more proportional fit
• The target is tall — S-03 (46 cm height, dome-shaped) offers maximum interior volume
• An ultra-flat profile is required — S-06 (ø 42 cm, only 19 cm tall)
• Mid-range coverage with lighter weight — S-07 (ø 45 cm, 5.7 kg)
• Greater coverage diameter is required — M-series (ø 51–73 cm) or L/XL series

The S-05 works well as a standalone landscape element on open lawns, or as the widest piece in a multi-stone arrangement using different GARTENDEK models.

Will the S-05 fit over my large manhole cover?
The S-05 provides ø 49 cm interior coverage and stands 23 cm tall. Standard heavy-duty round garden manholes in the EU are typically ø 38–45 cm — the S-05 covers them with clearance. For covers wider than ø 49 cm, move to the M-series (starting at ø 51 cm).

How do I install the S-05?
No tools or anchoring required. Place the S-05 over the object on any surface — grass, soil, gravel, paving. For equipment access, lift with both hands — it weighs 9 kg.

Is the S-05 stable in wind?
The broad base footprint (66 × 51 cm) and 9 kg weight provide excellent stability — the widest ground contact area in the S-series. In very exposed positions, secure with a low-profile tent peg through the base rim.

Can the S-05 stay outdoors year-round?
Yes. The fiberglass composite is rated from −30 °C to +60 °C. No seasonal removal is needed.

Will the colour fade in the sun?
The marble chip gelcoat contains UV stabilisers. Under standard EU sun exposure, no significant colour shift or chalking is expected over the 10-year service life.

What is the difference between S-05 and S-03?
Both are premium-tier models (~€254). S-05 (66 × 51 × 23 cm, ø 49 cm coverage) is the widest and flattest — for wide, low objects. S-03 (63 × 50 × 46 cm, ø 45 cm coverage) is the tallest — for objects that need height clearance.

Can the S-05 cover a tree stump?
Yes — this is one of its primary use cases. The S-05 covers tree stumps up to ø 49 cm in diameter.

Can I step on the S-05?
Yes. The composite structure supports static loads of 100+ kg.

Can I drill holes for cables or pipes?
Yes. The GFK composite can be drilled with special masonry drill bits or hole saws, or cut with a stone-cutting disc on an angle grinder. Since the walls are typically 10–15 mm, this can be done in a few minutes.
