In the so-called air-foams is a reticulated foam having an open-pored structure. The closed cells of the foam are a reaction by a hydrogen-air-water-oxygen mixture burst open explosively released by heat. Health Damaging vaporous hazards arise in this process, since the foam not too high temperatures or open flame or direct sunlight.

Air foam has the advantage that it, because of its open porosity a much lower water absorption, and especially a higher heat passage. This comes just then wear when considering underfloor heating in sports floor system.



Elastic surface soils are composed of a rigid load distribution layer (surface), and an elastic supporting structure. This combination meets the requirements for secure stability, sliding behavior, lasting dents and rolling loads. In area-elastic systems, a distinction is made between spring floors and the sandwich systems. The sandwich systems, in contrast to spring floors, have a lower primary mass. This leads to a better response in collisions, especially with lighter athletes, such as children. In addition, the load distribution underneath elastic foam is much more homogeneous than spring floor systems.



Describes the rebound height of a basketball in percentages of the sports floor, opposed to an unyielding floor. A higher ball rebound allows for better game performance.



Ball tossing safety includes all technical fixtures in the gym. The DIN 18032, part 3 describes the ball tossing safety as, “Equipment is counted as secure of ball tosses, when mechanical strains in the gym facilities through balls remain without significant changes in the construction of the equipment”. The ball toss security will be checked with a standard tester in a laboratory. In that process, the equipment will be shot at under predefined angles using handballs and hockey pucks.



Many different factors play a role in building materials. On the one hand, the functional as well as the safety requirements must be met in accordance with DIN 18032 Part 2, on the other hand, the requirements by Technical Approval must be fulfilled.
Especially in gyms or multipurpose halls good indoor climate plays an important role. For that reason, the German Institute for Construction technology (DIBt) set up specific regulations. Only those manufacturers, who meet all requirements regarding fire safety and emission levels (VOC), receive construction supervisory approval. This ensures users receive a secure and long-term health and fitness.



As the name suggests, this system combines the advantages of surface elastic flooring with the benefits of the point-elastic surface. It consists of an elastic structure with an unyielding load-distributing layer and an elastic part in the upper surface.



Conduct under rolling load describes the resistance of the sports floor against high rolling strains. During testing, the elastic point systems receives a rolling load of 1000 N, and all other systems obtain a load of 1500 N. This test embodies high strains for the sports floor, such as those caused by mat rolling cars.



The deformation trough describes the extent of distortion of the sports floor under the influence of a test specimen. With that, the trough outlines the distance from the test specimen center up to a predefined distance (w500 = 500mm, w100 = 100mm) in relation to the standard deformation. It determines the maximum propagation of the deformation of the sports floor.



The European Standard (EN 14904) "Surfaces for sports areas - Indoor surfaces for multi-sports use - Specification" was published in 2006, and has been validated in all member countries since 2008. The EN standard introduces new requirements for the functionality of indoor sports flooring and multi-purpose use in accordance with the individual athlete's body. In general, the following properties are tested according to EN 14904:

• Friction

• Vertical ball behavior

• Shock Absorption

• Standard deformation

It also includes further criteria for fire safety, as well as its emissions.



The sliding friction of the sports floor depends primarily on the type of surface covering. It must be consistently even on the whole surface in order to avoid injuries such as twisting of the ankle or the tearing of a ligament. The friction value must be between 0.4 and 0.6 m. However, even the best sports flooring is useless, if it is maintained incorrectly. The Becker Company strongly recommends suitable cleaning and maintenance materials, such as those provided by the company “Ideenfeder”. These can easily be purchased through our online shop.



Sport equipment, such as plug socket bars, lowerable high bar, wall bars, volleyball courts, or even tennis posts are wholly or partially attached to the building. For the installation and anchoring of the equipment, on-site arrangements in accordance with DIN 18032-6 and DIN loads 1055/Teil 3 and EN 1270 must be followed and approved.
The necessary ground sleeves are, dependent on the sports equipment manufacturer, either stainless steel, galvanized steel or aluminum. The fixtures must be completed in time before the installation of the sports flooring system.
The flooring is the main point of contact between athletes and object. Therefore, it must also provide the most important sport-functional and technical protection.
But even the best sports flooring can only develop its best qualities with correct care and henceforth minimize the risk of injury. Consequently, the cleaning and care of the sports hall is of utmost importance to the business.
Often errors are committed by the false use of products unapproved by the sports business. In turn, these errors will often hurt your athletes.
To be on the safe side, only use cleaning and care products, which guarantee to fulfill the required characteristics according to DIN 18032. Therefore, be sure to ask the manufacturer of your sports floor system. The Becker Company recommends the cleaning and maintenance materials of the company “Ideenfeder”.



The smallest unit of a sports hall is the 1-field-hall.


  • It has a height of 15m (W) x 27m (L) x 5m (H), derived from
  • 2-field halls (22m (W) x 44 (L) x 7 (H)),
  • 3-field halls (45m (W) x 27 (L) x 7 (H)),
  • and the 4-field halls (30m (W) x 54m (L) x 7m (H) or 60m (W) x 27m (L) x 7m (H))


Athletes are not only at risk during a fall to the floor, but also when hitting the walls of the gym with great force. Here impact protection walls serve for safety. They cushion a direct impact by giving way and therefore minimizing the collision. Here one differentiates between area-elastic impact protection and point elastic systems. Point-elastic systems usually consist of a textile material. Elastic surface impact protection walls are made ??of wooden materials.
To ensure optimal protection the Federal Association of Accident Insurance Institutions of the public sector (BAGUV) demands that gym walls must be covered in perforated materials up to two meters in height. One must also remember that when games are diagonally played, the lateral walls perform the function of longitudinal walls.



Numerous materials are suitable for heat insulation. Classically, one utilizes polystyrene (PS), which is Styrofoam, mineral fiber insulation or rigid polyurethane foam.



This serves to adjust the height in the sports hall. Specially designed for dynamic loads and heavy duty, dust-free insulation and leveling compound is applied to reach the required leveling on the ground. During subsequent operation, the embedment is solidified under high pressure and thus forms a pressure-resistant insulating board by itself.



The desired playing fields are standardized in accordance with the relevant, current guidelines of the sporting associations and after applying a top layer sealing of highly abrasion-resistant two-component PU-field color. Upon request, halls that are too small for tournaments may be standardized to other measurements. Please contact your professional exporting company in a timely manner.
Since most gyms are used for various sports, an intersection of lines is usually inevitable. Therefore, a ranking of the most important sports is set in advance, allowing the company to ensure that the lines of the main fields have as few interruptions as possible. The official colors and widths of the pitch markings are defined in DIN 18032-1:2003-09.



A common choice for floor covering is linoleum. Linoleum is made of environmentally friendly ingredients such as linseed oil, rosin, wood flour, cork, powdered limestone and jute. Linoleum is known as extremely tough, efficient, durable, ecological and hygienic flooring. Linoleum is available in two thicknesses (3.2 mm and 4.0 mm). Linoleum also offers many different colors, leaving you with the choice of many modern and fresh colors.



The moisture barrier is used as a waterproofing membrane at the screedsconstructions (in accordance with DIN 18195-4) and as a vapor barrier of the intra level ceiling. It is used as a bituminous sheet for waterproofing buildings against ground moisture or water (in accordance with EN 13969:2005). Additionally it is employed as bitumen vapor barrier membrane in accordance with EN 13970:2005. The moisture barrier allows for different variations to be used. Some are welded, whereas others are installed through cold gluing. Typically, the additional PE foil is not intended as a moisture barrier.



Ball catching nets protect spectators, as well as furnishing and equipment in the gym. They are attached behind the goals on the main field. This also means, an additional protection is added to the wall construction.
The type of net varies from sport to sport. The net in soccer, for example, has a mesh of 100 millimeters, whereas hockey requires a 45 millimeter mesh.



Point elastic systems have an elastic layer and a pliable surface. This allows for a healthy adjustment of the floor to the athlete’s. Due to the immediate response of the soil it meets its protective function even with light loads. It does not, however, have a load distribution. Due to this nonexistent excessive roller resistance, it is not suitable for cycling and roller sports. 



PUR foams are used in all sandwich systems (DYNAlast), which do not used for floor heating. This layer has the same function as the air foam coating, which is to compose the elastic layering. There are various thicknesses (15 - 20 mm), different densities and different forms with or without studs.



Screed is used in the gym to compensate for bare floors. By applying screed, one also succeeds in evening out the possible required floor heights. It should be noted, however, that sports floor usually has a much more complex building construction than other soils. Tip: Becker’s company allows for the recognition of the construction height of the pure sports ground by its identification number of. For example, DYNAlast 27 has a construction height of 27 mm.



The small area elastic sports floor consists of components of the point elastic sports floor and an additional floor-stiffening component. This reduces the disadvantages of the flexible surface of the point elastic floor. In addition, it is designed to reduce the surface hardness of the elastic soil.



There are various sports floor constructions:
1. Area-elastic sports floor
Elastic surface soils are composed of a rigid load distribution layer (surface), and an elastic supporting structure. This combination meets the requirements of stability, the sliding behavior, the residual indentation depth, and rolling loads.
In area-elastic systems, one distinguishes between sprung floors and sandwich systems. The sandwich systems have, in contrast to the sprung floors, the advantage of a lower primary mass. This leads to a better response in collisions, especially with lighter athletes, such as children. In addition, the load distribution is much more homogeneous than in sprung floor systems, due to elastic foam covering the bottom surface.

2. Point-elastic sports floor
Elastic point systems have an elastic layer and a flexural soft surface. This causes the athlete’s foot to comply into the surface in its individual adjustment. Due to the immediate response of the soil, even small units of pressure meet the protective function. Point elastic floors, however, do not have an equal balance in load distribution and are therefore not suitable for cycling and roller sports, due to the excessive rolling resistance.

3. Combined Elastic Sport Floors
As the name suggests, this system combines the advantages of surface elastic floors with the benefits of point-elastic soil. It consists of an elastic structure with a rigid load-distributing layer and an elastic part on the upper surface.

4. Small Area-elastic Sport Floors
Consisting of components of the point elastic sports floor and an additional surface- stiffening component, small area-elastic floors reduce the disadvantages of flexible surface of the point elastic floor. Through this construction it additionally reduces the surface hardness of the surface elastic soil.



In choosing the right floor one must consider the usage in different sports. Therefore, there are plenty of solutions for each purpose and each sport. These vary from area elastic sports floor systems, to point-elastic floors, or even mixed or combined elastic floors. In order to find the right floor for your application, use our online advisor!

A common choice in floor coverings is linoleum. Linoleum is made from environmentally friendly ingredients such as linseed oil, rosin, wood flour, cork, powdered limestone and jute. Linoleum is known to be extremely tough, efficient, durable, environmentally friendly and hygienic flooring. Linoleum is available in two thicknesses. 3.2 mm and 4.0 mm. Linoleum even offers a color scheme for all tastes, leaving you to choose between many modern and fresh colors.



Standard deformation defines and measures the degree of deformation of the sports floor under the pressure of weight. The higher the measured standard deformation, the lower the risk of injury of athletes from falls. However, the functional properties of the sports floor sports can be negatively affected if the standard deformation value is too high.



Thermal insulation is primarily dependent on the so-called thermal conductivity, and the supplementary material thickness. Thermal conductivity describes the rate of heat transitory of a material. Therefore, the lower the thermal conductivity-value, the lower the heat conductivity of the material and thus the higher the quality of the material in regard to thermal insulation. Thermal conductivity value is calculated from the heat passing per meter (thickness). If one reduces the thermal conductivity of the material and simultaneously increases the density in the same relation, the layer thickness of the material is obtained, and one reaches the same thermal insulation performance.



There are various types of upper lining, and the choice seems to be a difficult one. Especially with upper lining, the technical features, such as frictional sliding or reflectance, do not play the sole role. Individual optical preferences go hand in hand with the choice in upper lining.
Consequently, there are various types of parquet, linoleum floor coverings, PVC floor coverings, rubber or even homogeneous PU coatings to choose from.
