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.

A note on fit before you order. The dimensions above are interior guidelines, not a fit guarantee. Before ordering, we strongly recommend contacting the GARTENDEK team with the exact measurements of your equipment (diameter, height above ground, clearance around it) — we will confirm whether this stone fits your installation and, if needed, recommend a different model or a customised version.

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.

Warranty

The GARTENDEK warranty on artificial stones is 5 years from the date of delivery.

The warranty does not cover:

• mechanical damage;
• cosmetic changes (natural gelcoat matting, minor degradation of the outer layer due to UV exposure);
• exposure to aggressive chemicals;
• use other than intended;
• modifications not agreed with GARTENDEK.

The warranty applies in addition to the consumer's statutory rights under applicable EU legislation.

Composition logic

The S-05 is the largest broken-edge boulder of the sharp-ridge / broken-edge family (Group A). In a multi-stone composition it naturally anchors a Group A scene — pair it with the compact peaked S-01, the flat elongated S-02, and/or its lighter low-profile twin S-07, all in the same colour, for a credible weathered fieldstone group. Across sizes it also reads with M-02 and L-01 (sharp-edge companions), with XL-02 as an extended plateau, and sits quietly under the giant XXXL-01 anchor. Two S-05 stones side by side work only at clear visual distance; for a tighter group, combine S-05 with S-01 or S-07 of the same colour for a natural silhouette rhythm. Avoid mixing S-05 in a close composition with the round-boulder family (S-03, S-06, M-01, L-02, XL-04) or with the chopped-rocky trilogy (S-04, M-04, L-04) — the shape languages do not blend. When using multiple stones of the same colour in a close group, expect natural tonal variation of the marble-chip gelcoat.

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.

Shape-family positioning

Beyond dimensions, S-05 has a defined role in the GARTENDEK shape taxonomy: it is the largest broken-edge boulder of the sharp-ridge / broken-edge family (Group A: S-01, S-02, S-05, S-07) — the visual anchor of a Group A scene, wider and more weathered in character than the compact S-01 or the flat slab S-02, and heavier than its low-profile twin S-07. Across sizes it shares a shape language with M-02 (sharp-edge pair), L-01 (sharp-edge large), XL-02 (extended flat plateau with sharp grain) and sits quietly under the giant XXXL-01 anchor. Choose S-05 when the scene needs a wide weathered anchor in a sharp-ridge composition — or when the concealment target is a wide, low ground-level object that outgrows the compact S-series models.

6.1 — Why this section exists

Environmental claims in garden products are often vague — "eco-friendly", "sustainable", "green" — without quantifiable evidence. This section provides specific, verifiable comparisons between the GARTENDEK S-05 and the alternatives it replaces, so the buyer can make an informed decision based on data, not marketing labels.

6.2 — Weight reduction vs. natural stone

A natural granite fieldstone of comparable visual size (approximately 66 × 51 × 23 cm) weighs between 80 and 200 kg. The GARTENDEK S-05 achieves the same visual and functional result at 9 kg — a reduction of 89–96 % in material mass.

This is not a minor optimization. It is an order-of-magnitude reduction that changes every downstream process: extraction, transport, handling, and installation.

6.3 — What the weight difference means in practice

6.4 — Longevity as a sustainability factor

The S-05 is engineered for a service life of 10+ years without maintenance, repainting, or sealing. A budget plastic cover (HDPE/polyresin) typically degrades in 2–4 outdoor seasons — meaning 3–5 replacements over the same period.

Each replacement cycle consumes new raw materials, generates packaging waste, and adds transport emissions. A single durable product that lasts a decade or more is inherently less wasteful than a series of disposable ones.

6.5 — Material honesty

The S-05 is made from multi-layer fiberglass composite (GFK) with a marble chip gelcoat (ISO/NPG class). We do not describe this material as "eco-friendly" or "green". Fiberglass composite is an industrial material — it is not biodegradable, not compostable, and not currently recyclable through standard municipal waste streams.

What it is: extremely durable, weather-resistant, and long-lived — which reduces the total number of products manufactured, shipped, and discarded over time.

6.6 — Manufacturing footprint

The S-05 is manufactured in the EU (Italy) and dispatched from Slovenia. Production occurs in a controlled workshop environment — no quarrying, no blasting, no heavy earthmoving. The manufacturing process uses fiberglass layup and gelcoat application — standard composite techniques with relatively low energy input compared to stone extraction and processing.

6.7 — Packaging and shipping

Each stone is packed in a wooden crate with stretch film, hand-grip openings, and PVC ties. At 9 kg net (approximately 14 kg gross with packaging), the S-05 ships as a standard parcel via DPD, GLS, or national postal operators.

No pallet freight, no tail-lift truck, no special handling. Standard parcel logistics have a significantly lower per-unit carbon footprint than heavy freight delivery.

6.8 — What we do NOT claim

• We do not claim the S-05 is "carbon neutral" or "zero waste".
• We do not claim fiberglass composite is a "green" material.
• We do not claim the product is recyclable through household recycling.
• We do not use biodegradable or compostable packaging (the wooden crate and stretch film are chosen for protection, not environmental signaling).

6.9 — Summary: measurable environmental advantages

The GARTENDEK S-05 is not a "green" product in the marketing sense. It is a durable, lightweight, efficiently delivered product that reduces quarrying, transport emissions, and replacement waste through engineering rather than labeling.

Will the S-05 fit my specific equipment?

The dimensions listed above are interior guidelines, not a fit guarantee. Before ordering, contact the GARTENDEK team with the exact measurements of your installation (diameter, height above ground, clearance around the object). We will confirm compatibility and, if needed, recommend a different model or a customised version.

Can I place two S-05 stones next to each other, or mix S-05 with other models?

The S-05 is the largest broken-edge boulder of the sharp-ridge / broken-edge family (Group A: S-01, S-02, S-05, S-07). Its best multi-stone companions are the other Group A stones — S-01 (compact peaked ridge), S-02 (flat elongated slab), S-07 (lighter low-profile twin) — in the same colour, and across sizes it shares a shape language with M-02, L-01, XL-02 and the XXXL-01 anchor. Two S-05 stones side by side work only at clear visual distance; for a tighter group, combine S-05 with S-01 or S-07 of the same colour for a natural silhouette rhythm. Avoid mixing S-05 in a close composition with round-boulder models (S-03, S-06, M-01, L-02, XL-04) or with the chopped-rocky trilogy (S-04, M-04, L-04) — the shape languages do not blend. When stones are placed close together, keep the colour consistent — grey with grey, red with red — and expect natural tonal variation in the marble-chip gelcoat.

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. Snow and ice do not damage the surface.

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. Choose S-05 for wide manholes and tree stumps; choose S-03 for tall pumps and valve assemblies.

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, flush with or slightly above ground level. The wide flat profile rests naturally over the stump area.

Can I step on the S-05?

The composite structure supports static loads of 100+ kg — safe for accidental foot traffic, pets, and light garden furniture placed on top.

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. This allows you to route cables, pipes, or hoses through the stone wall. Since the material does not have very thick walls (typically 10-15 mm), this can be done in just a few minutes.
