Reason No. 1: Eco-friendly
Unlike the open-cut method, "no-dig" methods contribute significantly to saving energy and protecting the climate, given that construction- and congestion-related emissions caused by dust and CO2 (generated as a result of road construction waste, excavation and transporting large excavation volumes) are avoided.
Reason No. 2: Saving resources
Valuable pavement and green spaces, gardens, parks and residential streets remain untouched. There are no costs for remedial action, unlike with the open-cut method.
"Time" is also a valuable resource – trenchless methods are much faster, saving both time and money.
Reason No. 3: Sustainable
Complete pipeline renovations using hose-liner technology, which has proven itself over many years of use, allows for an average technical service life of 50 years and more.
Pre-condition: carefully coordinated components and a professional installation.
Reason No. 4: Safe Method
Hose-lining methods are tested and certified under a multitude of quality-assurance regulations, particularly the "Technical Approvals" issued by the German Center of Competence in Civil Engineering (DIBt). Even if this is not compulsory for the public sector, and instead serves the purpose of protecting private construction projects, our DIBt approvals are an indispensable aid when it comes to assessing and evaluating the required quality criteria.
