Artificial stone For Garden L-04

The Height Barrier Only L-04 Can Break

The core problem: Garden and utility equipment ø 61–67 cm taller than 42 cm has no concealment solution in the GARTENDEK range without L-04 — L-03 is too narrow and too short, L-01 is too short, and L-02 is discontinued.

Who needs the L-04:

• Owners of tall pool sand filter assemblies (ø 55–65 cm) where total height with multiport valve reaches 43–45 cm — no other GARTENDEK model provides clearance
• Vertical well pressure stations with tall pump + hydropneumatic tank assemblies (ø 55–65 cm, height 43–45 cm)
• Tall manifold irrigation control cabinets with multi-zone solenoid assemblies stacked to 43–45 cm
• Electrical transformer enclosures and tall utility boxes (ø 55–65 cm) with connection heads exceeding 42 cm
• Raised manhole sections with deep concrete collars bringing the top to 43–45 cm above grade
• Properties needing the tallest possible concealment stone in the entire GARTENDEK range — L-04's 45 cm is unmatched

Before ordering — verify fit. Measure the widest point (diameter) and the tallest point (height above grade, including raised collars, multiport valve heads, or timer housings) of the object you intend to conceal. L-04 fits objects up to ø 67 cm and height ≤ 45 cm. If width exceeds ø 67 cm, review L-01 (ø 80 cm, H 37 cm). If your object fits comfortably under ø 60 cm and H 40 cm, L-03 is lighter and cheaper.

Construction, Installation & Technical Specifications

The principle is simple: a hollow polyresin shell placed directly over the equipment on any surface — grass, soil, gravel, paving. No tools, no foundation, no site preparation. Fully open base with no internal partitions — lift the stone to access equipment underneath.

Installation:

• Two persons required (19 kg — heaviest in L-series)
• 10–15 minutes from unboxing to placed
• Positioning: at 19 kg, plan placement carefully to minimise relocation frequency; each move requires two people
• Equipment access: lift the stone for servicing — two-person lift
• Wind stability: 19 kg with compact footprint (87 × 83 cm) provides the strongest natural stability in the L-series — heaviest model is inherently most wind-resistant

Ventilation: Fully open base with non-sealed ground contact. Natural micro air exchange between interior cavity and surrounding environment on grass, gravel, or uneven terrain.

Technical Specifications

Material and Durability

The L-04 is constructed from UV-stabilised polyresin — engineered for permanent outdoor use in European climate conditions. The surface features realistic mineral texture replicating natural boulder grain and depth.

At 19 kg, L-04 is the heaviest L-series model. A natural stone of comparable dimensions (87 × 83 × 45 cm) would weigh approximately 300–500 kg. At 19 kg, the L-04 achieves a 94–96% weight reduction while maintaining the visual appearance of natural stone.

Available in Gray colour (colour not formally confirmed in Products DB — verification pending).

Note: Material is designated as polyresin in the SSOT. Other GARTENDEK models (e.g., L-03, L-01) use GFK composite with marble chip gelcoat (ISO/NPG). The material designation difference may warrant harmonisation in product documentation.

• UV-stabilised — permanent colour retention under direct sun
• Frostproof — no cracking at sub-zero temperatures; engineered for EU climate
• Fully waterproof — sealed surface, no moisture absorption
• Static load capacity: 100+ kg
• Service life: multi-year permanent outdoor exposure
• Maintenance: rinse with a garden hose. No sealing, painting, or chemical treatment required.
• Safety and load limitations — the product supports 100+ kg under normal conditions. Not a load-bearing structure, not designed for impact loads. Use in children's and public zones possible with pre-agreed usage scenario, engineering adaptation, and safety coordination.

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 Anchor of the Chopped-Rocky Trilogy

L-04 is designed as the L-scale anchor of the chopped-rocky trilogy (S-04 + M-04 + L-04). In a multi-stone composition, the three rocky models work as a coherent family: S-04 as the small foreground accent, M-04 as the mid-scale companion (ø 51 cm), and L-04 as the tallest structural centrepiece (ø 67 cm, 45 cm height). Avoid pairing L-04 with Group A sharp-ridge stones (S-01, S-02, S-05, S-07, M-02, L-01, XL-02, XXXL-01) — the chopped-rocky language conflicts with the sharp-edge language. Avoid pairing with Group B round field-boulders (S-03, S-06, M-01, L-02, XL-04) — the faceted rocky surface does not match the smooth rounded silhouette. Do not substitute L-04 with L-03 when building the rocky trilogy — L-03's weathered-outcrop form belongs to the solo-statement group, not the rocky family. Maintain the Gray colour throughout the trilogy for visual consistency.

What Can the L-04 Conceal?

The ø 67 cm coverage diameter, record 45 cm height, and compact 87 × 83 cm footprint make the L-04 purpose-built for tall, mid-diameter concealment scenarios:

1. Tall pool sand filter assemblies — the complete vertical stack — filter tanks ø 55–65 cm with multiport valve + connecting pipework, total height 43–45 cm; L-02 (42 cm) and L-03 (40 cm) are insufficient; L-04 is the only model that provides clearance
2. Vertical well pressure stations with tall casings — pump + hydropneumatic tank assemblies reaching 43–45 cm height, ø 55–65 cm
3. Tall manifold irrigation control cabinets — multi-zone solenoid valve assemblies stacked to 43–45 cm including timer housing
4. Electrical transformer enclosures and tall utility boxes — ground-level boxes ø 55–65 cm with connection heads extending above 42 cm
5. Raised manhole sections with deep collars — underground utility access with concrete raising rings bringing the collar to 43–45 cm above grade
6. Compact upright decorative boulder accent — the 87 × 83 cm near-square footprint creates a classic vertical field boulder silhouette; ideal where the elongated L-02 (108 × 86 cm) would be disproportionately large

Ventilation: The L-04 base is fully open with non-sealed contact with the ground surface. When placed on grass, gravel, or uneven terrain, natural micro air exchange is possible between the interior cavity and the surrounding environment.

L-04 in the L-Series

L-04 vs L-03 — Same Length, Different Geometry

Both share 87 cm length but serve different purposes. L-04 is 18 cm wider, 5 cm taller, and 5 kg heavier. Decision rule: Object fits under L-03 → take L-03 (lighter, cheaper, one person). Object ø >60 cm or H >40 cm → L-04.

L-04 vs L-01 — Tallest vs. Widest

L-01 is the widest and flattest model (ø 80, H 37 cm). L-04 is the tallest and most compact upright model (ø 67, H 45 cm). No overlap — they serve opposite geometry needs.

Cross-Series Coverage Ladder (Height Focus)

Shape-Family Positioning — Chopped-Rocky Trilogy Anchor

L-04 is the L-scale anchor of the chopped-rocky trilogy: S-04 (S-scale small rocky accent), M-04 (ø 51 cm, M-scale chopped-rocky companion) and L-04 (ø 67 cm, 45 cm height, L-scale structural centrepiece). The three rocky models share a faceted / weathered surface language and are designed to be placed together as a three-stone scene — in contrast to the solo-statement models (M-03, L-03, XL-01), which are designed to anchor a zone on their own, and to the sharp-ridge Group A and round field-boulder Group B families. If a garden uses multiple GARTENDEK stones, L-04 should appear alongside S-04 and M-04, not mixed with Group A or Group B members.

My pool filter assembly is 63 cm wide and 44 cm tall with the multiport valve. Will L-04 fit?

Yes. The ø 67 cm interior clearance accommodates the 63 cm width, and the 45 cm profile height covers the 44 cm assembly with margin. No other GARTENDEK model can fit objects ø >60 cm at heights above 42 cm.

Why does L-04 require two people for installation?

At 19 kg, L-04 is the heaviest model in the L-series. Two-person installation ensures safe handling and precise placement. Each subsequent relocation also requires two people.

How does L-04 compare to L-03 if both are 87 cm long?

L-04 is 18 cm wider (83 vs. 65 cm), 5 cm taller (45 vs. 40 cm), and 5 kg heavier (19 vs. 14 kg). L-03 is for objects ø 52–60 cm at heights ≤40 cm. L-04 is for objects ø 61–67 cm or heights >40 cm. If your object fits under L-03, choose L-03 — it's lighter, cheaper, and one person can install it.

What is the difference between polyresin and GFK?

L-04 uses UV-stabilised polyresin. Other GARTENDEK models use GFK (fiberglass composite) with marble chip gelcoat. Both materials are engineered for permanent outdoor use. The specific material designation follows the SSOT (Products DB).

Is it hollow?

Yes. Fully hollow, open on the underside. No bottom panel, no internal partitions.

Can it stay outdoors year-round?

Yes. UV-stabilised polyresin is frostproof and waterproof — engineered for permanent outdoor use in European climate conditions. No seasonal storage required.

Why is L-04 out of stock?

L-04 is currently marked as out of stock on gartendek.com. Restocking is a priority (P0). Check the website for updated availability.

Where is it manufactured?

In the European Union — VSDN d.o.o., Slovenia. GARTENDEK is the product brand of VSDN d.o.o.

How do I verify that L-04 will fit my object before ordering?

Measure the widest point (diameter) and the tallest point (height above grade, including raised collars, multiport valve heads, and timer housings). L-04 accepts objects up to ø 67 cm and height ≤ 45 cm. If the object is wider than ø 67 cm, consider L-01 (ø 80 cm, H 37 cm). If it comfortably fits under ø 60 cm and H 40 cm, L-03 is lighter and cheaper.

Can I combine L-04 with other GARTENDEK stones in one garden?

Yes — L-04 is designed as the L-scale anchor of the chopped-rocky trilogy. For a coherent multi-stone composition, pair L-04 with S-04 (S-scale rocky accent) and M-04 (M-scale rocky companion). Avoid placing L-04 next to Group A sharp-ridge stones (S-01, S-02, S-05, S-07, M-02, L-01, XL-02, XXXL-01) or Group B round field-boulders (S-03, S-06, M-01, L-02, XL-04) — the surface languages conflict. Maintain the same Gray colour across the trilogy for visual consistency.
