Gardeners & Hydrorock
We help gardeners with ecologically responsible solutions for flooding and water shortages on terraces, gardens and landscaping. Everything grows and blooms better with Hydrorock infiltration blocks.
The environmentally friendly solution for flooding and water shortage in the garden and public green areas
Nuisance but also water shortage are the most underestimated problems in the gardens. In the event of flooding, private individuals and companies often suffer from subsidence of the terrace, entrances and exits, garden paths. But algae growth, bald spots in the lawn up to and including mold formation in the house are also common. And then we have not yet talked about moderate or poor growth of plants and trees with too much or too little water in public landscaping. These are matters that gardeners deal with almost daily.
“Maximum result with minimum effort; everything grows and blooms better with Hydrorock ”
The sustainable system for the gardener, client and the environment
Hydrorock supports gardeners with the construction and maintenance of terraces, driveways and exits and gardens. The use of Hydrorock offers the solution both in times of excessive rainfall and in constant drought. We do this by efficiently disconnecting rainwater drains, collecting, retaining and draining rainwater where it falls. The use of Hydrorock prevents flooding by gradually absorbing the excess water on each site and releasing it to the surrounding soil.
Flora and fauna thrive excellently on Hydrorock®
Sustainability and environmentally friendly use of materials are increasingly being discussed. Hydrorock infiltration blocks are made of stone wool, a 100% natural material. It is particularly strong and resistant to erosion by plant and tree roots and the ecologically responsible solution for entry and exit, terrace and garden for your clients. Thanks to the disconnection solution and the buffer function of the Hydrorock infiltration blocks, flora and fauna enjoy rainwater longer and water shortage and dehydration of the soil can be prevented as much as possible. In this way we contribute to the satisfaction of your customers in the construction and maintenance of every terrace and garden.

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 blocks have a fine-grained fiber structure in one direction. A horizontal fiber direction promotes a drainage function. A vertical fiber direction promotes an infiltrating function. Due to the load-bearing capacity of the blocks, these must always be positioned in a vertical position for buffering and infiltrating action (the sticker with the text "this side up" is then on top). If bearing capacity is of secondary importance, the blocks can also be used horizontally for drainage purposes of surface and rainwater. For optimum drainage, we recommend placing the blocks one behind the other and in a horizontal position (lying down). You will find the placement instructions in the here.
Hydrorock is produced from stone wool, a 100% natural material. It remains underground for decades in optimum condition. Hydrorock is resistant to erosion by plant and tree roots and will continue to function well for years. The cotton-based membrane of filter cloth does not mold or rot. It has a high breaking strength and is resistant to the natural substances in the soil. Stone wool is 100% recyclable. Flora and fauna thrive excellently on Hydrorock.
If the blocks are positioned correctly, the system requires no maintenance. Unlike other solutions, running in of soil is not possible in this system. The blocks therefore do not need to be inspected or cleaned. When uncoupling rainwater discharges it must be prevented that dirt blocks the pipes. This is easy to do by placing a foliage and sand catcher. These systems are easy and quick to clean. If there is a wish to still be able to clean the system extra, we advise you to install the uncoupling system in a loop. In this way the system can be sprayed through and therefore easy to clean should there still be some dirt blockage.
