What is German floor foundation?

A German floor or mass concrete oversite is basically a concrete bed or floor at the top of the foundation of a house.

It is a non-reinforced concrete structure that  separates  the walls of the foundation of a house and the walls of the ground floor.

For better understanding and for the purpose of this article let us say that a German floor is a non-reinforced concrete structure at the top of the foundation of houses or rather a slab that covers the foundation of houses immediately after the earth filling.

The German floor of the foundation of a building basically prevents water from penetrating the walls and rooms in that building and as a structure of its own, it helps to stabilize the weight of a building by controlling the building’s level at the foundation stage, especially when done correctly.

So if a German floor is a concrete bed that covers the top of a foundation, why is German floor important in houses?

Is German Floor Compulsory in Houses?

One of the questions house owners ask during the construction of their house is ‘Is it compulsory to do German floor?

The straight answer is yes.

Yes because every building plan includes the German floor (mass concrete oversite), so why would you want to exclude it in construction? It is compulsory, especially for storey houses.

However, if you are building a bungalow, you might exclude it at the foundation stage and do it later, before or after roofing your house.

Conclusion

German floor or concrete oversite is a vital structure in houses as seen in this article, but one of the reasons some house owners argue about its necessity on some types of houses during construction is because of its cost involvement.
However, you should always adhere to the instruction of your builder or contractor to include a German floor in the foundation of your house because most builders and contractors will always insist that you include it in your house.
If you follow the information in this article, you can have a clear understanding of how much the German floor of the foundation of your house may cost before its construction and don’t forget to do some market research to know the actual cost of building materials in the location where your house is to be situated.

Builders then, said German floor will be done before roofing. 7 years gone by I couldn't continue my project. All these years the building is without a roof. Now i would like to finish it but not sure if I can still get the German floor done.
