TECHNICAL SUPPORT
Detailed Technical Support
The foundation of every successful lining design
At Dolenco Tunnel Systems, we understand that proper technical support is crucial for achieving optimal drainage solutions. Our experienced engineering team provides comprehensive and innovative support throughout every phase of your project.
Pre-Project Consultation
System Design Assistance includes geological condition, water ingress pattern analysis, structural integration planning, and custom system configuration.
Product Selection Guidance provides module type recommendations based on specific conditions, flow management evaluation, integration with existing waterproofing systems, and long-term performance projections.
Project Planning Services
Our technical team assists with specification development for tendering, integration planning and coordination with other construction systems, timeline optimization for project efficiency, and life cycle cost optimisation and comparisons.
Maintenance & Service
System Monitoring – The tunnel can be systematically scanned to identify any blockages and standing water in the installed Dolenco Drain System using non-destructive methods.
Maintenance Procedures include mechanical cleaning of drainage channels, blockage removal techniques, performance verification methods, and preventive maintenance scheduling.
Optimise Your Lining Design
Getting the optimal solution requires more than quality products—it requires expertise in proper system design, installation excellence, performance optimisation, and risk mitigation. Our technical support ensures that every Dolenco installation delivers the permanent water pressure prevention that your project demands.
Frequently Asked Questions
What is the Dolenco Drain system?
The Dolenco Drain is an integrated water drainage and pressure-relief system designed for tunnels, basements 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.
In what types of construction can the Dolenco Drain system be used?
The system is used for a wide range of underground structures including tunnels, basements, utility shafts, stations, hydropower, mining and retaining walls. For both new and existing structures.
Can the Dolenco Drain be combined with other waterproofing systems?
Yes. Dolenco Drain is a standalone water management solution, but can be combined with waterproofing systems, additives, injection systems, or protective coatings depending on project specifications and exposure conditions.
What maintenance is required once Dolenco Drain is installed?
The system is designed to be maintenance-free under normal conditions. Proper installation ensures continuous water flow through the drain network, even clogging is avoiding pressure buildup and secures a design permanently preventing pressure.
How does the Dolenco Drain differ from other water management solutions?
Where concrete and waterproofing are designed to withstand pressure and being resistant to water seeping through different types of cracks and porosity etc, Dolenco Drain eliminates hydrostatic water pressure, which is the cause. This proactive approach significantly reduces the risk of leakage, cracking, and long-term maintenance costs.
What materials are used in the Dolenco Drain system?
Dolenco Drain moduless are made from durable, chemical-resistant materials, 100% recyclable or 100% biodegradable, with high compressive strength. They are designed to maintain full drainage capacity even under high loads and long-term groundwater pressure.
How does the system contribute to sustainability and lower life-cycle costs?
By eliminating water pressure and minimizing repair needs, Dolenco Drain reduces material consumption and CO₂ emissions over the structure’s lifetime. It also reduce construction time and overall life-cycle cost (LCC).
How is water captured at the base?
Waterflow is managed at the base depending on the individual project design.
A number of details can be implemented, including Dolenco Gutter Drain, designed to also be used in very slim structures.
During design, the optimal solution is discussed on the basis of the initial design criteria, to optimise the final lining design.
