Take control of your roots ZONES

This innovative system has been designed to proactively manage soil moisture content and remove excess water from the soil profile. It also helps to boost ventilation of the soil and helps provide gas exchange in the root zone.

This brings benefits throughout the year, with better temperature moderation in the root zone during the summer months, and help with the operation of the undersoil heating system in the winter months.

The SISAir system can make a significant contribution to developing a better playing surface, reducing ongoing maintenance costs and lowering the risk of damage to the playing surface.

how the sisair system works

To achieve subsurface aeration, water removal and gas exchange, the SISAir system forces air movement through the soil profile beneath the grassed playing surface. Thanks to blower fan connection with a series of variable control dampers to a specially designed air and drainage pipe network the system can create either vacuum or pressure in the soil profile.

An automatic air non return valve is also incorporated into a water separator to provide a means of closing off the piped drainage network from the gravity drains. This system enables air to flow up or down in pressure or vacuum mode through the soil profile.

The pressure blower fan, associated mechanical equipment and the control panel for the SISAir system are located in a plant room under the stadium terraces. This equipment is connected via an underground air pipe to the water separator and the network of pipes laid under the grassed playing surface.

The SISAir system is managed via an operator touch panel located in the plant room that enables manual operation, pre-set daily scheduled operation and other integrated with it, for example, irrigation and heating systems. The control system can be easily upgraded to a fully automated system controlled by in ground sensors, external weather station, retractable.
