Rockflow® rainwater retention and infiltration systems

At ROCKWOOL Rainwater Systems, we believe in sponge cities; cities that absorb rainwater and put this valuable resource to good use. By fostering a healthy urban water balance, sponge cities are better adapted to the effects of climate change, such as heavy rainfall and excessive heat.

Powered by Rockflow® stone wool, we create sustainable, durable solutions for stormwater storage and infiltration, delayed discharge, treatment and reuse, helping to build future ready sponge cities.

Rockflow retention and infiltration systems are stormwater management solutions made from Rockflow stone wool by ROCKWOOL Rainwater Systems. They support water conscious sponge cities by storing rainwater, enabling infiltration, providing delayed discharge, treating water, or making it available for reuse.
