What's wrong with a monolithic slab foundation?
"The world does not consist of black and white," wrote Bulgakov in his novel "The Master and Margarita", and this seemingly simple truth applies to all, even the construction! The world of building materials and technologies is designed so that unambiguously positive or negative technology there.
All this is a long construction and literary preface leads us to the fact that of the monolithic slab foundation has its drawbacks, not only the benefits, which was devoted to previous article.
Disadvantages of a monolithic foundation:
- Everything for monolithic slabs need a smooth surface, which is governed by SNIP. Do you want to experiment - deviate from the SNIP, but every sane builder adheres to them.
- Laying the foundation of a monolithic arrangement cuts off the possibility of the basement or cellar.
- It is practically impossible to build an additional communication in a continuous body of a monolithic slab foundation. water supply and drainage lines must be laid up to the plate casting.
- Next - our favorite - the economy: a monolithic slab - the most expensive type of foundation, the cost of materials and work with them can compete unless UWB.
Thus, the solid foundation is expensive - which is better to pour on the surface with only a slight slope (ppm, even degrees), deprives you of the possibility to equip the basement or cellar, but calling for the careful planning of communications at the initial stage construction.
