The wall is built on a generally valid basis

Who wants to build a wall, has many variants to choose from. In addition to the function of the wall, building materials and surface texture determine the construction. Add to that the desired dimensions in thickness, height and length. A fundamental difference is between load-bearing, non-load-bearing walls and wet or dry construction.

Great variability obeys the same basic physical laws

The designs of walls and walls are sometimes hardly comparable. A lower stone wall in the garden is hardly reminiscent of a load-bearing building wall. The self-made screen is more like a fortified Spanish wall.

When building a wall yourself, the stability is always paramount. Depending on the function and construction, this is achieved by means of a suitable base attachment, anchoring to ceilings or other walls and a durable substance. Common to all walls are some basic rules of building physics and statics.

Factors influencing the building and setting of a wall

Every vertical component or structure has in common that it "fights" against gravity. In addition to this downward automatic pulling force, gravity helps to make sloping walls fall over. The acting forces are calculated in Newton and follow a relatively simple equation. Gravity must have less energy than the durability of the wall. Many factors affect these properties of a wall:

  • height
  • thickness
  • Dry or wet construction
  • Free stand or holding work
  • Building material and construction method (individual components, finished or cast plates)
  • Lateral forces (wind)
  • Texture of the subfloor

Reinforcement methods for a wall

A wall can gain increased internal stability when created by reinforcement. Steel gratings are cast in concrete walls. Also grid reinforcements applied from the outside are possible. In wall structures with cavities support elements are retractable. Wall corners can be reinforced by diagonal struts.

When selecting a foundation for a wall, the classic types of foundations in construction offer a selection of construction-specific advantageous designs. Floor foundations carry a wall over the entire surface (strip foundations) or at points (single foundations). The top width and thus the wall foot can be increased to increase the stability.

Modification and modifications to build yourself

If, for example, a wall is provided with a superior second wall for the purpose of insulation, the static conditions change. When doubling the wall cross connections of the two formworks can be connected.

When retrofitting a wall, lateral and upper anchorages are decisive for the design. Attention must be paid to possible loads, such as those caused by partially or completely suspended ceilings or support beams or struts.

The static calculation of a wall always refers to a complete trade and its integration into the situation. This planning rule applies to freestanding walls as well as to building walls of all kinds. If a change occurs on the walls, as is the case with an extension, the overall calculation must be repeated. Simple "patching" can cause the overall statics to waver.

Tips & Tricks

There are several design alternatives for almost every wall construction project. Do not believe any provider a supposed lack of alternatives and weigh individually advantages and disadvantages.
