The Dolenco Drain is an integrated water drainage and pressure-relief system designed for basements, tunnels, and other underground concrete structures. It prevents water pressure from building up behind the structure by collecting and redirecting groundwater through a controlled drainage layer.

Unlike conventional waterproofing membranes that only resist seepage, Dolenco Drain eliminates hydrostatic water pressure altogether. This proactive approach significantly reduces the risk of leakage, cracking, and long-term maintenance costs.

The system is suitable for a wide range of underground structures including basements, tunnels, parking garages, utility shafts, water reservoirs, and retaining walls. It is adaptable to both new constructions and renovation projects.

Dolenco Drain panels are made from durable, chemical-resistant plastic materials with high compressive strength. They are designed to maintain full drainage capacity even under high loads and long-term groundwater pressure.

Yes. Dolenco Drain can function as a standalone drainage solution or in combination with waterproof membranes, injection systems, or protective coatings depending on project specifications and exposure conditions.

By eliminating water pressure and minimizing repair needs, Dolenco Drain reduces material consumption and CO₂ emissions over the structure’s lifetime. It also shortens construction time and reduces overall life-cycle cost (LCC).

The system is designed to be maintenance-free under normal conditions. Proper installation ensures continuous water flow through the drain panels, avoiding clogging or sediment buildup over time.

The system is developed and supplied by Dolenco ApS in Denmark – specialists in water pressure management and drainage technology for underground concrete structures. The company provides design support, product supply, and technical assistance worldwide.
