Urbanization is accompanied by a significant increase in paved areas, which the existing drainage system and sewerage system is not designed for. As a result, the water cannot reach the soil and cannot infiltrate.
Hydrorock makes it possible to infiltrate into the soil by means of disconnecting water that falls on roofs and paving. In this way flooding is prevented in a natural way and the sewerage system is relieved. In addition, the soil is prevented from drying out and the moisture balance of the soil is restored.
Hydrorock significantly reduces the risk of damage from flooding.
Due to urbanization and climate change, the soil dries up, resulting in a disturbed moisture balance in the soil.
Hydrorock makes it possible to temporarily store water in the soil and releases this water gradually. In this way, dehydration is prevented in a natural way and the moisture balance in the soil is restored.
Hydrorock significantly reduces the risk of damage from dissection.
Hydrorock makes it possible to irrigate water underground. This prevents the evaporation of precious water and nutrients.
With the Hydrorock sub-soil irrigation solution we create a data-driven, fully automatic irrigation system.
Hydrorock makes it possible to temporarily store water in the blocks and gradually releases water through underground irrigation.
This brings and keeps the moisture balance around the root system in optimal condition.
The solution for all your flooding, made from the 100% natural stone wool material. Molten rock that is spun into fibers and formed into a block, encased in a membrane of erosion-resistant filter cloth. Lifelong operation and immediately ready for use.

The speed with which Hydrorock blocks blocks of water depends on how the water can reach the blocks. If water comes in direct contact with the blocks, the speed at which the blocks absorb the water is approximately 400 liters per m2 per minute. If water reaches the blocks via a porous layer of, for example, sand, then sand has a delaying effect in this case and is then also normative. The absorption capacity / permeation speed of porous sand is approximately 50/60 liters per hour, which means that 50 liters of water on an area of 1 m2 takes 1 hour to sink into this. Absorption of water via the perforated tube in type BD blocks proceeds at a speed of 100 liters per linear meter of tube per minute.
Hydrorock has a special product line for private individuals under the brand name Hydroblob®. There is an extensive dealer network for this range. There is usually a point of sale in your area. View our special Hydroblob website for more information.
The connection to the rainwater drainage is done by connecting the rain pipe to the Hydrorock blocks of type BD. This version has a perforated tube (ø 100mm) that runs through the block so that the water can run into the block. The tube can be connected to rainwater drains, street vents, pipes, drainage hoses, gutters, etc. These blocks can be mutually coupled in the longitudinal direction by means of a small piece of perforated tube. The buffer capacity can be increased by placing a type D block without tube on the side (s) of type BD. The blocks pass the water on to each other.
Hydrorock International has professional dealers in many countries. We are happy to link you to one of these points of sale. Hydrorock International also has official dealers outside Europe. In China, for example, Hydrorock is used to collect rainwater from highways. In Australia our official dealer sells Hydrorock primarily to prevent drying out. View all our current points of sale here.
