GARTENDEK M-01 — Large-Format Hollow Artificial Stone Cover
ø 73 cm Coverage | 109 × 89 × 27 cm | 13 kg | GFK + Marble Gelcoat (ISO/NPG) | EU-made
The GARTENDEK M-01 is a large-format hollow artificial stone cover that conceals ground-level utility equipment up to ø 73 cm in diameter — the entry point to the M-series and a category leap from the entire S-series. With an external footprint of 109 × 89 cm at just 27 cm height, it replaces visible pool pumps, septic tank lids, transformer boxes, and large manhole covers with a massive natural granite boulder accent that blends seamlessly into the landscape.
Constructed from multi-layer fiberglass composite (GFK) with a marble chip and marble powder gelcoat surface (ISO/NPG class). Color is formed by embedding natural stone chips directly into the gelcoat — not painted, not printed. Available in Gray and Red. Handcrafted in the EU (Italy/Slovenia). €377.74 including delivery. 10-year warranty.
The problem with large utility equipment
Gardens and outdoor spaces contain large functional elements at ground level that no small stone can cover: pool pump and filter housings (ø 50–70 cm), wide septic tank lids (60–70 cm), large manhole covers, transformer boxes, irrigation manifold clusters, and well assemblies. These objects are too wide for any model in the S-series (maximum coverage ø 49 cm).
Homeowners face limited choices: leave industrial-looking equipment exposed, invest in a natural stone boulder weighing 300–500 kg (requiring crane delivery and permanent placement), or accept flimsy plastic covers that crack, fade, and look artificial within 2–3 seasons.
How M-01 resolves it
The M-01 closes this gap. At 109 × 89 × 27 cm with ø 73 cm interior coverage, it is designed specifically for objects too wide for any S-series stone. The broad, low-profile asymmetric boulder form sits naturally in large gardens, driveways, and spacious landscape zones. At 13 kg, it is placed by two people in under 2 minutes — no tools, no foundation, no site preparation.
How it works: material, installation, durability
Material and structure: The M-01 is constructed from a multi-layer fiberglass composite (GFK) — the same material class used in marine construction (boat hulls). The outer surface is natural marble chips and marble powder in an ISO/NPG class gelcoat. Color is integral to the material — formed by adding natural stone chips and stone dust directly into the gelcoat compound. It is not paint, not film, not print. Available in two colours: Gray and Red. Handcrafted production (“In Handarbeit gefertigt”) — colour and dimensional deviations of 3–5 cm are within normal range.
Installation: No tools, no foundation, no site preparation required. Place the stone over the target object on any surface: grass, soil, gravel, paving. Installation time: under 2 minutes. Two people recommended for comfortable transport and placement (13 kg). For equipment access — lift the stone. The broad base (109 × 89 cm) combined with 13 kg weight provides excellent wind stability.
Durability:
- Frost-proof to −30 °C
- UV-stable to +60 °C
- Fully waterproof — no moisture absorption, no swelling, no delamination
- Static load capacity: 100+ kg
- Declared service life: 10+ years permanent outdoor exposure
- Maintenance: rinse with water and a soft brush (no sealing/painting/chemicals)
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. Use in children's and public zones is possible with a pre-agreed usage scenario, engineering adaptation, and coordination of safety requirements.
Material comparison: M-01 vs alternatives
| Criterion | GARTENDEK M-01 | Natural stone | Budget plastic (HDPE / polyresin) |
| Weight | 13 kg | 300–500 kg | 5–10 kg |
| Hollow interior | ✅ Conceals equipment | ❌ Solid | ✅ Hollow |
| Visual realism | Marble chips in gelcoat | Natural stone | Paint/print — fades in 2–3 seasons |
| Load capacity | 100+ kg | Unlimited | Not rated |
| Service life | 10+ years | Unlimited | 2–4 years |
| Installation | Two people, <2 min | Crane / heavy machinery | One person |
| Price | From €378 | €1,000–5,000+ | €80–200 |
| Production | EU (Italy / Slovenia) | Natural quarrying | Predominantly China |
This is why M-01 is positioned as a “natural stone look” solution with realistic surface (marble in gelcoat) and long service life, without the logistics and permanence of 300–500 kg real boulders.
10 practical scenarios for the M-01
- Concealing a swimming pool pump and filter system — standard filter housings ø 50–70 cm fit comfortably under the 73 cm coverage
- Covering a large septic tank lid — standard 60 cm and 70 cm concrete or plastic lids are fully hidden
- Hiding a large manhole cover / inspection chamber — in a lawn, flower bed, or driveway
- Concealing an electrical transformer box (Trafohaus) — utility cabinets at ground level disappear under a natural boulder
- Covering an irrigation distribution manifold — multiple valve outlets and T-connectors fit within the wide base
- Hiding a well pump assembly — wide casing and surface equipment concealed under a single stone
- Concealing a rainwater tank lid — underground cistern access point replaced with a landscape element
- Covering a cluster of pipes and cable junction boxes — groups of utilities exiting the ground hidden by one stone
- Hiding a garden feature base — fountain equipment, water feature pump housings concealed
- Concealing a compact heat pump compressor unit — low-profile configuration fits under the 27 cm height
Why M-01 vs other M-series models
| Model | Coverage ø | Height | Dimensions (L×W) | Weight | Price | Best for |
| M-01 | 73 cm | 27 cm | 109 × 89 cm | 13 kg | €377.74 | Widest base, low profile |
| M-02 | 73 cm | 23 cm | 89 × 79 cm | 11.50 kg | €337.48 | Same ø, smaller footprint |
| M-03 | 80 cm | 32 cm | 85 × 83 cm | 15 kg | €378.24 | Max coverage diameter |
| M-04 | 51 cm | 42 cm | 68 × 62 cm | 11.50 kg | €335.71 | Tallest, compact diameter |
Decision rule: Choose M-01 when the object is wide (up to ø 73 cm), you need maximum ground/base coverage, and a low profile (27 cm) suits the landscape. For same ø 73 cm in a smaller body — M-02. For maximum diameter (ø 80 cm) — M-03. For tall narrow objects — M-04.
From S-series to M-series — the category leap
The S-series covers objects up to ø 49 cm (S-05). When your target is wider than 49 cm, you need the M-series. The M-01 is where that starts.
| Series | Max coverage ø | Representative model | Price |
| S-series max | ø 49 cm | S-05 | €254.20 |
| M-series entry | ø 73 cm | M-01 | €377.74 |
M-01 covers 49% more diameter and approximately 122% more area than S-05. This is not an incremental step — it is a category leap.
Within the M-series, M-01 holds the largest-footprint position: widest body (109 × 89 cm), same ø 73 cm as M-02 but with 38% more base area and 4 cm more height clearance.
