Long service life, easy maintenance

Reliable buffer capacity throughout its entire service life

Designed for long service life and easy maintenance

Rockflow is designed for a life span of more than 50 years. During this time, the system will collect, hold and infiltrate rainwater many times.

Like all infiltration systems, Rockflow stone wool is also subject to sedimentation, caused by particles that are transported into the system by the incoming water. These sediments do not end up in the stone wool matrix but accumulate in the channels over time, where they can cause blockages. This reduces the system's water absorption capacity and speed.

The water channels are easy to inspect and clean if necessary. After cleaning, the absorption rate and buffering capacity are restored. This ensures a consistent performance of the system over its entire service life.

The channels in Rockflow water channels are easy to inspect and clean. This can be done time and time again using standard equipment (special nozzle for infiltration sewer and push camera) for sewer cleaning. The stone wool is not damaged. With a good system design, any inflow of dirt can easily be removed using water pressure. After being cleaned, the system will be like new again

Inspect first, then clean

A Rockflow system does not always need to be cleaned. The frequency of cleaning depends on environmental factors and precipitation events. We therefore recommend that you always inspect the system first to determine if cleaning is required or not.

No worries about compression/ settlement

Stone wool retains its shape and size, even under heavy loads (20tonnes axle load). This is confirmed by research by the independent research institute Deltares and our own tests in practice. Rockflow therefore complies with civil engineering standards.

Root infiltration? No problem!

A Rockflow system is perfectly suitable for a green environment. Root growth does not have a negative effect on the operation of the system, unless the roots obstruct one of the water channels.
