The ideal foundation for tennis courts

Long lasting fun

Thanks to its self-leveling nature, lightweight composition, and exceptional strength, foam concrete makes SuperSub highly resistant to subsidence and cracking. This ensures the foundation stays perfectly level for years, providing consistent and long-lasting performance. Furthermore, SuperSub’s shock-absorbing properties help reduce the risk of injuries, while its sound-dampening effect keeps the surrounding neighborhood and nature calm and content.

Play at top level, all year round

Clay courts are popular among tennis players, but traditional clay often struggles with rain and frost. By choosing a combination of Matchclay or Top Clay with a SuperSub® foundation, you can enjoy consistent playing conditions all year long. SuperSub is self-leveling, lightweight, and strong, making it virtually resistant to settling or cracking. This keeps your court flat and playable for years to come.

In addition, SuperSub’s shock-absorbing properties reduce strain on joints and muscles, while its sound-dampening qualities contribute to a quieter environment — a welcome benefit for the neighborhood!

Simple and fast installation

Thanks to its lightweight design, SuperSub can be installed quickly and efficiently, even in hard-to-reach areas or on soils with limited load-bearing capacity. Our project supervisor always performs a final check to ensure the project runs smoothly. After that, our own team pours the foundation — usually completed within a single day! This guarantees top quality and minimal disruption.

Sustainable with SuperSub

SuperSub meets the latest standards and guidelines of NOC*NSF. Its production and installation are environmentally friendly and fully recyclable. Producing 1,000 liters of SuperSub requires only 100 liters of material, reducing transport movements by 90%. If the field ever needs to be removed, SuperSub can be easily separated from the base layer without contamination. This results in a CO₂ footprint approximately 80% lower than traditional foundations.

Structure and Construction

The thickness of a SuperSub foundation usually ranges between 10 and 18 cm, depending on the situation and requirements. Converting a tennis court into a padel court? That’s possible with SuperSub too: for conversion projects, we typically apply 10 cm of SuperSub. For a new tennis court or an all-weather clay court, the standard thickness is usually 15 cm.
