Block (prefabricated) strip foundations are the fastest in terms of construction method. But all blocks have standard sizes, so they are not always available, so that the tape is continuous. To fill the empty space (voids) strip foundations, the best building material is sand concrete M300 – consumption can be significantly reduced, if the work is completed in the shortest possible time. The ready-mixed mixture will allow you to quickly prepare concrete, how to manually, as well as mechanized – in a concrete mixer.
Installation of the foundation, made up of blocks, produced with a crane and with the involvement of human resources.
Block base of the building, consisting of several rows, has some features regarding filling gaps between large blocks:
– gap filling, after the installation of all rows, it reduces the strength of the foundation;
– filling voids at the time of foundation work increases the lead time, Consequently, costs also go up;
– filling the gaps in the tape row of blocks is much more difficult after laying the next row.
To maintain the load-bearing properties of the foundation and reduce installation time, it is necessary to pre-produce all blocks of non-standard sizes. Expanded clay is ideal as a filler. Blocks will have less weight., without negatively affecting the load-bearing characteristics. The most important, insert loops, to place the unit in the desired location using a crane.
Sand concrete can also be used for preliminary floor screed. At this stage, it is better to use sand concrete M300: the consumption of the solution from the finished mixture at home will be the most reasonable solution.
