Cons of Blocks
The strip foundation made of FBS has a number of disadvantages. The laying resembles the assembly of a construction set, so it is important to pay attention to the adhesion of the blocks to each other. Monolithic masonry forms a flat surface, so the structure does not require additional reinforcement, unlike a block foundation.

If the cement mortar is poured poorly, gaps are formed between the layers, through which cold air and moisture penetrate. To further insulate the building, cavities are filled with slag or expanded clay during construction. Waterproofing materials, which are used to line the base, prevent premature destruction of the foundation.

If the foundation is laid out from large blocks, special equipment may be required.

Types of foundations
Before starting construction, it is necessary to decide on the type of foundation.


Pile. Suitable for construction of structures (bathhouses, garages) on soils with high acidity and groundwater (deep occurrence).
Linear. One- or two-story residential buildings are built on a linear foundation.
Foundation and building blocks (by design) are:

Empty. Low-strength material, used for singapore mobile database fences. Low weight is provided by the emptiness inside the block.
Monolithic. The reinforced concrete structure is equipped with grooves and is used for the installation of communication systems.
Solid. The blocks are connected to each other in advance, forming a square. To increase strength, the structure is additionally reinforced.
Selecting blocks by size allows you to calculate the parameters of the structure being erected in advance and draw up an estimate.

How to select block sizes
When purchasing FBS, you must adhere to the following recommendations:

Manufacturer. The quality of the material directly depends on the manufacturer. You need to buy FBS made at the factory. Handicraft slabs have lower compression ratings. Before buying, you need to study reviews of a particular material.
Accuracy of geometry. FBS with accurate geometry is faster and easier to lay. Much depends on the technology of slab production. If concrete is poured into special forms, the block is smooth. When using the technology of immediate stripping, the slabs will have a trapezoidal cross-section. They provide a large support area, so this type of material is used in the construction of buildings in seismically hazardous areas.
Communication places. They are determined in advance. In order not to drill holes in solid slabs, you need to purchase special FBS.
For the construction of residential buildings, it is preferable to use slabs with a length of 238 cm. The use of such FBS will reduce the number of vertically located seams.
