Strong enough to replace concrete but also draining, HippoTiles have several unique properties.
They are extremely porous, acting like a sieve, not a sponge. They have a fifty times greater flow rate than sand. They do not allow any particles beyond the top layer, ensuring the drainage beneath stays clear and clean.
They are very strong and have been tested to withstand weight of 1,000 tonnes per square metre with no degradation in performance.
They are both flexible and elastic which makes them very comfortable and allows them to be installed very securely.
