The Concept

RockDrain is a environmentally safe drainage system that constitutes a monolithic construction. It requires no bolts for installation and is unaffected by suction and compression forces. It interacts with the rock mass instead of concealing it (enabling inspections). RockDrain is resistant to fire and requires less space in tunnel cross-sections. Installation is less resource-demanding and significantly faster than other systems. The construction is easy to repair, does not require tunnel closures during repairs. RockDrain has a service life of 120 years, both LCC and LCA figures are significantly lower.
