Closed-Cycle Garden Fountain Systems — No Concrete, No Construction
Modular fountain kits with underground HDPE basins and composite stones. Closed water cycle, manual installation, no heavy equipment. Designed and manufactured in the EU.
Installing a water feature on a property is typically a multi-week project: concrete, plumbing, drainage. According to market data, the budget in Europe starts at €5,000 and frequently exceeds €10,000, with a timeline of two to six weeks — not counting permits.
GARTENDEK Water Decor is a different approach — a modular garden fountain system with a closed water cycle. All components — the underground HDPE basin, pump, and composite fountain stone — are engineered to work together as one system.
Water circulates in a closed loop: it rises through the stone, flows over the surface, and returns to the basin. No connection to mains water, no drainage, no chemicals — on the surface you see only stone and moving water.
The system is installed entirely by hand, without concrete or heavy machinery, so it can be added to finished gardens and patios without disturbing lawns, paths, or existing landscaping.
Underground basins are made from HDPE — the same high-density polyethylene used in municipal water systems. The structure supports loads from 500 kg and is designed for long-term underground use, with a rated service life of over 50 years and freeze tolerance down to −15 °C.
Fountain stones use the same multi-layer composite technology as GARTENDEK artificial stones: gelcoat, fiberglass, and natural marble chips. They are designed for permanent water contact and year-round outdoor use from −30 to +60 °C. Available as individual elements or as part of complete fountain kits.
Installation requires only manual excavation, basin placement, and pump connection. The only requirement is a 220–240V electrical connection. This allows homeowners, landscape designers, and contractors to integrate a fountain into existing lawns, pathways, and hardscape without large-scale construction.
The modular architecture — separate basins, stones, pumps, and electrical cabinets — lets you configure solutions at any scale: from a compact entrance fountain to multi-stone water compositions in professional landscape projects.
All systems are designed and manufactured in the EU under GARTENDEK quality control.
