What are the most common mistakes when building a padel court?

Building a padel court seems simpler than it is. You choose a location, request a quote and a few weeks later you are playing. Unfortunately, that is rarely how it goes in practice. Many clients run into the same problems: a foundation that is not up to standard, a structure that does not suit the site, or costs that turn out much higher than expected. In this article, we list the most common mistakes so that you can avoid them.

Which mistakes are made most often when building a padel court?

The most common mistakes when building a padel court are a wrong or undersized foundation, no structural calculation per site, insufficient attention to noise requirements, choosing a contractor purely on price and underestimating hidden costs. Each of these mistakes can lead to higher costs, delays or a court that does not meet the requirements.

What stands out is that most mistakes are not made during construction itself, but in the preparation. Anyone who decides too quickly without asking the right questions pays the price later. Below, we discuss each mistake separately, with practical advice on how to approach it better.

Why is a wrong foundation such a big mistake with a padel court?

The foundation determines the stability, lifespan and playing quality of a padel court. A wrong or too light foundation leads to settlement, tilting of the cage structure and damage to the artificial turf. In the worst case, the court has to be rebuilt after just a few years, which more than cancels out the initial saving.

There are three commonly used foundation types, each with its own characteristics:

• Drainage concrete is a water-permeable type of concrete in which rainwater drains directly through the foundation into the ground. Suitable for outdoor sites with good soil conditions. Average lifespan: 25 to 40 years.
• Supersub is a foundation solution based on foam concrete. It is light, self-levelling and shock-absorbing. In its outdoor version, Supersub is water-permeable and can be poured within a single day. Particularly suitable for converting existing sports fields.
• ZOAB asphalt (very open asphalt concrete) is a porous type of asphalt that lets water through. Less common for padel, but in certain situations a good choice.

The mistake that is regularly made: choosing the cheapest foundation type without taking the soil conditions into account. Without a cone penetration test in advance, you simply do not know what the soil can handle. Foundation advice based on cone penetration test data is not a luxury, but a necessary step. In the Netherlands, all foundation components must moreover be inspected by Kiwa ISA Sport. Anyone who works with non-certified materials risks the court later not qualifying for official matches or inspections.

What goes wrong if you do not have a structural calculation made for each site?

Without a structural calculation per site, you run the risk that the steel structure is not tailored to the specific conditions of your site. Think of wind load, soil conditions, surrounding buildings and any noise requirements. A standard structure that works well at site A may be unsafe or unsuitable at site B.

This is a particular problem with:

• Open sites or coastal locations with higher wind load
• Sites with deviating dimensions or limited height (indoor)
• Courts where sound-absorbing panels are used

That last point deserves extra attention. Sound-absorbing panels are placed on the outside of the mesh of the cage structure. They reduce the wind permeability of the structure, which increases the wind load on the court. The structure must therefore be structurally reinforced, with heavier posts, additional columns or modified connections. Anyone who skips this builds a court that does not meet the safety requirements and can cause problems in strong winds.

Importers and standard suppliers generally do not offer customisation at this level, certainly not for smaller numbers of courts. A site-specific calculation is therefore one of the points you should explicitly ask about when requesting a quote.

How do you choose a reliable contractor for a padel court?

You can recognise a reliable contractor for a padel court by three things: transparency about what is included, demonstrable experience with the complete process from foundation to handover, and the willingness to make a structural calculation per site. A party that only names a price without a specification gives you insufficient basis for comparison.

When selecting a contractor, pay attention to the following points:

• Does the contractor deliver everything from a single source? Many parties are in fact coordinators who manage various suppliers. If something goes wrong, the question of who is responsible quickly becomes a problem.
• Does the contractor work with certified materials? Foundation components and artificial turf must be inspected by Kiwa ISA Sport in the Netherlands. Ask about this explicitly.
• Does the contractor make a site-specific structural calculation? This is a technical obligation, not an extra service.
• How long is the warranty on the steel structure? This says a lot about the confidence a supplier has in their own product.
• Can the contractor show references from comparable projects? Ask about courts that have been in use for several years.

Also look at the origin of the steel structure. Many Dutch providers import their courts from Spain. That brings transport costs, longer delivery times and less flexibility for customisation. A manufacturer that makes the structure itself has more control over quality and scheduling.

What are the hidden costs when building a padel court?

The hidden costs when building a padel court lie mainly in the foundation, the permit process, noise measures and additional civil works. Anyone who looks only at the price of the superstructure has an incomplete picture of the total investment.

Concrete cost items that are often underestimated:

• Foundation: For outdoor padel courts this is the biggest cost item. Foundation costs are on average between €20,000 and €40,000, depending on soil conditions, accessibility and the civil works required.
• Permit process: An environmental permit takes time and money. Think of acoustic study, lighting study, structural calculations and site drawings. The lead time is on average 8 to 12 weeks.
• Noise measures: If the site is near homes, sound-absorbing panels or a noise barrier may be mandatory. These are separate cost items that are not included as standard in a basic quote.
• Groundwork and drainage: Not every site is ready for building. Earthmoving, drainage and levelling can raise the costs considerably.
• Inspection after handover: For official matches, an inspection by Kiwa ISA Sport is mandatory. This is a separate step that is sometimes forgotten in the planning.

As an indication, a standard indoor padel court is possible turnkey from approximately €23,000 per court. An outdoor padel court including foundation starts on average from approximately €50,000. The exact price always depends on the specific situation, the number of courts and the site conditions.

When are sound-absorbing panels mandatory for a padel court?

Sound-absorbing panels are not legally mandatory, but in practice municipalities increasingly make them a condition when granting permits. This applies in particular to sites near residential areas, where padel produces more noise than tennis, with an average sound power level of approximately 91 dB, around 10 dB more than tennis.

When do you come across noise measures in the permit process?

• If the padel court is placed outdoors near homes
• If the municipality makes an acoustic study mandatory
• If local residents object during the permit procedure
• If the court wants to apply longer opening hours, including in the evening

Sound-absorbing panels are placed on the outside of the mesh. They absorb the sound instead of reflecting it back, while the playing dynamics are preserved. Independently tested in an acoustic laboratory, this results in an airborne sound insulation of 22 dB and a noise reduction that is audible at distances of 40 to 100 metres.

Important: as soon as panels are used, the cage structure must be structurally reinforced. This is not optional. The panels reduce the wind permeability of the structure, which increases the wind load. A structural engineer must recalculate and adapt the court. In some cases a combination of panels and a freestanding noise barrier is the most effective, where the barrier can be built lower thanks to the contribution of the panels.

Which warranties should you demand when buying a padel court?

When buying a padel court, you should at the very least demand a warranty on the steel structure, clarity about the warranty terms for the artificial turf and the LED lighting, and assurance that the materials used are certified in accordance with Dutch standards. A supplier who does not explicitly commit on this gives you insufficient certainty for an investment that has to last for decades.

Concrete questions you should ask:

• How long is the warranty on the steel structure, and what are the exact terms?
• What warranty applies to the artificial turf and the coating of the structure?
• Have the foundation components and the artificial turf been inspected by Kiwa ISA Sport?
• Who is the point of contact for warranty claims: the supplier or a third party?
• What is the procedure if damage occurs within the warranty period?

A long warranty period on the steel structure, such as 15 years, is a strong indication that a supplier has confidence in the quality of their own production. Do note that warranties can differ per component. The warranty on the steel structure does not usually apply automatically to the coating, the artificial turf or the LED lighting. Always ask for the warranty terms in writing, per component.
