Foundation of FBS blocks

Dear visitors of the site, from the material presented by the author, you will learn how to independently build the foundation under construction houses from FBS blocks. The foundation of the house is naturally the correct installation of the foundation, but first of all it is necessary to conduct geological exploration and find out the degree of freezing of the soil, the presence and depth of groundwater, it is also necessary to know if there is a massive foundation on your site (quicksand), if available, is not recommended.

The advantage of building a foundation from FBS blocks is that it is not necessary to build the formwork, knit and weld the reinforcement, prepare a large amount of concrete mortar and order a mixer. After laying the blocks, you can immediately proceed to the next stage of laying the walls of the house, which reduces construction time by several times, because you do not need to wait until the concrete has dried and gained its strength, but this is at least a month of inactivity. So the facts speak for themselves.

And so, let's carefully examine what exactly is needed to build a foundation from FBS blocks?

Materials
1. FBS blocks
2. cement
3. sand
4. crushed stone
5. fittings
6. brick
7. concrete slab
8. bitumen mastic
9. waterproofing additive for concrete
10. clay

Tools and equipment
1. excavator
2. truck crane
3. shovel
4. Bulgarian (angle grinder)
5. welding machine
6. trowel
7. trowel
8. mallet
9. pegs
10. rope
11. roulette

Step-by-step instructions for the construction of a foundation from FBS blocks do it yourself.

Before proceeding with the installation of this type of foundation, you should familiarize yourself schematically with what it is. A pit and a trench digging, mainly with the expectation of a basement or basement. Next, a sand cushion of 15-20 cm is laid along the perimeter, it is tamped with a layer of small gravel also 20 cm above, everything is densely tamped. Then the blocks are already stacked, the masonry is the same as the brick "breakdown" so that there is a bundle between the blocks, it is also recommended to reinforce each row. During masonry, you also need to constantly check the level so that there are no distortions, which in the future can negatively affect the building itself.After the theory, the author proceeds to practice and marks the land he bought, for which he uses tape measure, pegs and a rope (white)Digging a pit, here you can not do without special equipment. The author hired an excavator.The excavator manages his work pretty quickly and skillfully.Then the author makes a marking under the foundation trench.Digs out according to the marking.A sand cushion of 15-20 cm is laid at the bottom, and on top of it is a layer of crushed stone of 20 cm.The surface of the pillow should be well compacted and even and the first row of blocks is already laid on it. Masonry is carried out using a truck crane and slingers, starting strictly from the corner.And so, the first row is laid out.After the row is laid, it should be reinforced in this way.The author covers the fittings with cement mortar.Causes risks and allows the cement to dry.And the second row of blocks went, the masonry is also carried out on cement mortar.The internal partitions of the basement floor are also laid.Basically lay out 3 rows of blocks.Overlapping is made of reinforced concrete slabs.Plates are also laid with a truck crane and the help of slingers. But we should not forget that the foundation can turn out not quite even and in order to fix this defect, lay out a row of red bricks.Also, the finished foundation should be covered with a waterproofing layer like bituminous mastic.The distance between the foundation and the moat is best filled with clay, because clay does not allow water to pass through well and is a natural preservative. It is only necessary to properly tamp.Thus, the author built the foundation of the house in a fairly short time, and then you can safely proceed to the laying of the walls of the house. Of course, this method has many advantages, but there are also disadvantages, according to the owners of the houses on the foundation of FBS blocks, there were cases of cracks in cement joints. Also today this technology is considered obsolete.
This material presented the positive and negative sides of the construction of this foundation, and of course it is up to you to decide.
