7 technical requirements for installing an indoor padel court in an existing hall

Turning an existing hall into a padel venue sounds simpler than it is. The hall is already there, the space is available and the demand for padel is high. Yet projects regularly stall on technical details that only come to light late in the process. Anyone who knows in advance where the bottlenecks are saves time, money and disappointment. Below you will find the seven technical requirements that every hall must meet before an indoor padel court is realistic.

What makes an existing hall technically challenging

An existing hall was built with a different purpose in mind. That means the dimensions, the floor, the installations and the structure do not automatically match the requirements of a padel court. Sometimes the adjustments are small and cheap. Sometimes they are drastic enough to call for a review of the business case.

The seven requirements below are not wishes but hard preconditions. They determine whether a location is suitable, what needs to be adapted and what makes the final investment realistic. Go through them one by one before you request a quote or bring in a contractor.

1: Clear height above the court

The clear height is the first and most visible requirement. The minimum recommended clear height for an indoor padel court is 6 metres, measured from the floor to the lowest obstruction above the playing area. Think of roof beams, light fixtures, sprinkler systems or skylights.

At a height of exactly 6 metres, playing is technically possible, but the quality of play is limited. High lobs and defensive play are penalised by the ceiling, which reduces the experience for players. For a professional venue or a commercially attractive environment, the higher the better. A clear height of 8 metres or more gives players the space they expect.

Also watch out for roof structures that slope down or where the height varies along the length of the hall. The minimum of 6 metres must apply across the entire playing area, not just in the middle.

2: Floor load and bearing capacity of the substrate

A padel court is not a lightweight structure. The steel structure, the glass and the foundation add considerable weight. The existing floor of the hall must be able to carry that weight without settling, cracking or deforming.

Ask the owner or manager of the hall for the technical documentation of the floor structure. What matters is the permitted floor load in kilonewtons per square metre and the build-up of the floor itself. A concrete floor on firm ground or prefabricated concrete elements behave differently from a floor on a sand bed or an old industrial floor with an unknown build-up.

If the bearing capacity is insufficient or unknown, a structural investigation is necessary. That costs time and money, but it prevents you from laying a foundation that causes problems later. Settlement or tilting in the steel structure is expensive to repair and directly affects the safety and lifespan of the court.

3: Foundation type suited to the hall

A foundation is also necessary for an indoor padel court. The steel structure has to be anchored and the playing surface must be flat, stable and durable. Which foundation type is most suitable depends on the existing floor and the soil conditions beneath it.

For an indoor location, the water-permeable variant of Supersub, a foundation solution based on foam concrete, is not used. Indoors, a non-permeable build-up is chosen that is matched to the indoor environment. Supersub is light, self-levelling and in many cases can be poured within one day. For renovation projects the thickness is generally around 10 centimetres, for new-build around 15 centimetres.

Drainage concrete, a water-permeable type of concrete with an open structure, is primarily intended for outdoor applications where water drainage is essential. Indoors this type is less relevant. A ring foundation with steel reinforcement can be used if the forces from the steel structure require extra anchoring. The right choice always depends on a site check and cone penetration test data of the subsoil. All foundation components must be approved by Kiwa ISA Sport.

4: Free space around the court

A padel court has a playing area of 20 by 10 metres, but the space needed in the hall is larger. At least 21 by 11 metres is needed for installation. For a comfortable playing experience with sufficient run-off zones, 21 by 14 metres is recommended.

The run-off space at the short sides of the court is the most critical. Players regularly run on through or past the back wall and need room to stop and return to the court. A run-off zone that is too tight increases the risk of injury and noticeably reduces the playing experience.

Also take into account the space needed for installation and maintenance. A steel structure is delivered in parts and assembled on site. If the hall offers little room to manoeuvre or access is limited, this can make installation more difficult and raise the costs. Measure the available space accurately and include the logistics of the construction phase in your planning.

5: Lighting standards and installation options

Padel requires good lighting for a safe and pleasant playing experience. The standard for match lighting is at least 500 lux on the playing area, evenly distributed without disturbing shadows or glare. For recreational use a lower level may suffice, but for a commercial venue meeting the match standard is a sensible choice.

LED lighting is the standard for indoor padel courts. Consumption is low, the lifespan is long and the light colour is easily adjustable. The fixtures are placed above or beside the playing area, depending on the roof structure and the available suspension points in the hall.

Check whether the existing electrical installation of the hall has sufficient capacity for the extra load of the LED lighting. With multiple courts the power requirement can quickly add up. Also ask whether the meter cupboard and the circuit distribution allow expansion, or whether a new connection is needed. This is a point that should be included in the quote and planning.

6: Ventilation and climate control

Padel is an intensive sport. Players produce heat and moisture, and without adequate ventilation the temperature and humidity in the hall rise quickly. That is not only uncomfortable but also harmful in the long term for the artificial turf carpet and the steel structure.

An existing ventilation system in the hall is not automatically suitable for padel use. The capacity has to be calculated on the basis of the number of courts, the expected number of simultaneous players and the volume of the hall. A system that is too weak leads to condensation, which can cause slippery floors, mouldy artificial turf and corrosion on the steel structure.

For halls with an existing climate system, it is wise to obtain building services advice before the courts are installed. Adjustments to the ventilation system are simpler and cheaper to carry out before the cage structures are installed than afterwards.

7: Sound insulation and acoustic requirements

Indoor padel courts produce considerable noise. The ball hitting glass and steel, combined with the cage structure acting as a resonance chamber, results in a sound power level of approximately 91 decibels. In an enclosed hall, that sound bounces back from the walls, ceiling and floor, which can affect the experience of players and bystanders.

For halls that border residential buildings or office space, an acoustic study is advisable, even though a permit for the indoor installation itself is not always mandatory. Sound insulation of the hall itself, sound-absorbing panels on the outside of the cage structure or acoustic ceiling panels are possible measures. Sound-absorbing panels are fitted on the outside of the mesh of the cage structure and absorb sound rather than reflecting it back.

An important technical point: when sound-absorbing panels reduce the wind permeability of the structure, the steel structure has to be structurally reinforced. This also applies indoors if the hall has large openings or if the panels cause wind load. The structure must be calculated for this before the panels are installed.

Technical check before the quote

The seven requirements above are not a checklist that you tick off once. They are interrelated and influence each other. A low clear height can limit the lighting layout. A weak floor can determine the foundation type. Sound-absorbing panels call for a heavier steel structure. Anyone who maps out all these points in advance avoids surprises during construction and gets a quote that matches the actual situation.

Gather the following information before you request a quote:

• Clear height at the playing area, including obstructions such as roof beams and installations
• Available floor area and free space around the desired courts
• Technical documentation of the floor structure and its bearing capacity
• Capacity of the electrical installation and the meter cupboard
• Presence and capacity of the ventilation system
• Location of the hall relative to homes or other noise-sensitive uses
• Any cone penetration test data of the subsoil

The more information is available, the more accurate the quote and the smaller the chance of additional work. Also take a look at the cost of an indoor padel court for a good idea of what a realistic budget involves.
