The most important moment in the construction of any structure is the creation of a foundation, without which the construction of the building is impossible. It is the stability and durability of the building that depends on the strength of the foundation. Thoroughness, correct calculation allowed our ancestors to build structures that delight us with their appearance, to this day. This is largely due to a properly prepared foundation. And it does not matter where the structures were built: in the swamps of St. Petersburg, in the water of Venice or in the desert near Cairo. As a material for the foundation, substances that are resistant to the destructive effect of moisture, which include brick, concrete and reinforced concrete are used as a material.
The simplest is the foundation built of blocks. Foundations made of blocks are called prefabricated. Depending on the building being built, you can use gas blocks, foam blocks and other block materials for the foundation. The cost of foundation blocks is cheaper than filling a monolithic foundation. In addition, in construction, time also has a price, moreover, considerable.
When laying the foundation by pouring into the formwork, it takes a lot of time to preparatory work, such as laying reinforcement, formwork device. And even more time goes to solidify concrete. For the construction of large structures, FBS blocks made of reinforced concrete are usually used. GOST 13579 allows the use of FBS, FBV, FBP blocks as the basis of the building. Blocks are made at the plants of reinforced concrete structures on an industrial scale. That is why the quality, size, composition of concrete and fillers are unchanged and comply with all the standards and standards in force in construction.
The most popular types of blocks that are necessary in the manufacture of the foundation are the following: FBS blocks that have no holes; FBP blocks with the presence of voids inside the P-shaped; FBV blocks with special recesses for laying communications. The weight of the blocks is from 350 to 500 kilograms. Blocks of the foundation price of which are most acceptable for buyers, you can purchase directly from the manufacturer, for example, in the DSK “Mytishchi”. The price ranges from 487 rubles to 3013 rubles per block.
The installation circuit of the blocks is a brickwork with the dressing of the seams “Route”. Masonry is carried out on a cement mortar, its height can be up to five blocks. Between the foundation blocks there may be small gaps for conducting underground utilities to the building. All horizontal and vertical joints and seams between the blocks should be completely filled with the solution.
