Build safe and for the future!

Environmentally friendly solution!

When a better solution comes - use it!

Waterproof tunnels,

excellent for most concrete constructions!

The RockDrain System

Water, fire, and frost -proofing tunnels and underground constructions in the most safe, environmentally, cost-effective and sustainable way.

Estimated savings for 16km tunnel in Sweden compared with membrane and full cast concrete – more than SEK 1.500.000.000 (USD 170 million – EURO 150 million)

The RockDrain-system achieved the highest classification possible in test done by The Swedish Traffic Administration.

The Next Big Thing in Concrete is Not Big at All -we use NANO TECHNOLOGY

Our line of environmental friendly and innovative waterproof and insulating concrete bring advantages into all concrete construction in general.

We use our own developed recipe and modern technology to improved the success they had in eg. Petra Jordan for about 2.200 years ago with waterproof concrete. 

Advantages, savings!

  • Lower Cost LCC 55% 55%
  • Increased lifespan 89% 89%
  • Better eutrophication 55% 55%
  • Less timeconsuming 62% 62%

Finished drained, fire, and frostproof tunnels and under-ground constructions in only 6 cm. 

At least 120 years lifespan.

Perfect for rehabilitations.

Lowest LCC (life cycle cost)

It´s hard to find any reason NOT to use this system!

The numbers does not lie

Water-, fire- and frostproofing system for tunnels and underground constructions.

Full-scale tested and evaluated by;

IVL – The Swedish Environmental Research Institute.

Compared with conventional frost and waterproofing method. The RockDrain System excels in all aspect!

Easy installation.
