What is the water absorption capacity of the infiltration blocks in terms of time?

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.

Is the Hydrorock International range also available for consumers?

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.

How many Hydrorock infiltration blocks do I need?

The number of required Hydrorock® blocks depends on the surface, the groundwater level and the soil type. Use our calculator to calculate how many blocks you need. Our calculator for disconnecting rainwater can be found here. Look here for solutions to prevent flooding

How are Hydrorock blocks connected to rainwater discharge or street drain?

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.
