Prefabricated concrete garage

Prefabricated concrete garages is the collective term for garages consisting of reinforced concrete - precast elements are made (. Cf. DIN 18 186, DIN EN 13978-1). Prefabricated garages are generally made from concrete reinforced with steel. This composite building material has a high load-bearing capacity and a long service life. In prefabricated concrete garages, it forms the shape of the component and takes over the static compressive forces that occur as well as protecting the reinforcement from corrosion .

production method

There are two different manufacturing processes for prefabricated concrete garages.

  • Use of a formwork machine in which the entire garage including the floor is built in one concreting process. This creates a monolithic, i.e. seamless, garage body.
  • With this variant, the longitudinal walls, rear wall, the door section and the roof surface are concreted in the formwork machine in one process.

There are three alternatives for producing the floor with this production variant:

  • The prefabricated floor is inserted into the formwork machine and then the garage body is concreted.
  • The prefabricated floor is welded or screwed into the concrete garage body.
  • After the body has been concreted, the floor is subsequently concreted in.

In all processes, a construction-related construction joint is created , which, however, does not impair the load-bearing capacity of the floor.

Furnishing

The interior of the prefabricated concrete garages is given a smudge-proof paint coat, the outer walls are given a weatherproof plaster. Depending on the manufacturer, the roof surface is designed differently (additional coating, gravel, greenery, etc.) and equipped with a water drain with a downpipe up to the outer edge of the garage. Gates, doors and windows can be selected flexibly according to the client's wishes. As a standard, however, a lacquered up-and-over door with a door leaf made of beaded steel is provided as the door . In recent years, the variety of sectional doors in particular has increased significantly.

Garage ventilation

The ventilation in a prefabricated garage is mainly due to the natural joint ventilation and is specifically supported by vent holes in the side or rear wall as cross ventilation between the garage door and ventilation holes. These ventilation holes are covered from the outside with ventilation grilles made of plastic, which work like weather protection grilles. These two types of ventilation are only used for dehumidification and to improve the indoor air quality in the garage. However, the engine must not be started when the garage door is closed, as there is a risk of poisoning.

Possible uses

Prefabricated concrete garages are available as single or row garages . In addition, these can also be built as an underground car park , double or double-storey car park . The manufacturers also offer prefabricated concrete garages for other uses. They are also offered as basement replacement rooms or rainwater storage tanks for sustainable rainwater use . Due to their manufacturing process, prefabricated concrete garages are very flexible in design and can, for example, also have round shapes.

Permits, building rights, border development

The manufacturers of prefabricated concrete garages usually provide type sheets for the respective garages as well as a type statics that are valid for them, which are attached to the building application . In some cases, the manufacturers offer to submit the building application. This saves additional costs.

When building garages, building law must be observed. Especially if buildings are planned directly on the border, the special regulations for border development must be observed. The manufacturers sometimes offer advice and information on this.

Preparation of the construction site, assembly

Prefabricated concrete garages do not require a circumferential foundation , usually reinforced strip foundations under the goal and rear wall are sufficient. Prefabricated concrete garages are delivered as a whole using a special transport or displacement vehicle. Therefore the accessibility of the construction site must be guaranteed. One advantage of prefabricated concrete garages is that they can be easily moved later.

advantages

  • approx. 50% price advantage compared to an equivalent brick garage
  • Another price advantage through personal contribution z. B. the foundation
  • the fixed price guarantee
  • long guarantees (up to 5 years)
  • a contractual partner, important for the warranty in the event of construction defects
  • short construction time, prefabricated concrete garages can be installed within an hour
  • Completion regardless of the weather
  • larger usable area due to thinner walls than brick walls

disadvantage

1. Cracking

  • Due to their construction, prefabricated concrete garages tend to crack in ceilings and walls. According to the standard for prefabricated concrete garages, DIN 18186, the durability of the garage is not impaired by individual cracks whose crack width does not exceed 0.4 mm.
  • Cracks <0.4 mm are not grounds for complaint.
  • The cracks that are often recorded are partly visually impairing and may reduce the resale value.
  • If the cracks> 0.4 mm are repaired, depending on the type of execution, they are permanently harmless, but the repaired areas remain visible.
  • Manufacturers and sales companies do not regularly point out this fact.

2. Condensation water

  • Prefabricated concrete garages tend to condensation on the walls and especially on the ceiling due to their construction, especially when there are sudden, weather-related temperature jumps.
  • In individual cases, the condensation water can lead to the formation of heavy drops and lead to "raining down" from the ceiling.
  • Storing things that are sensitive to moisture is not recommended, as the humidity in the air is sometimes very intense due to the formation of condensation.
  • Manufacturers and sales companies regularly refer to this fact in a rather belittling way and explain "correct" ventilation behavior by the user.
