Good day dear visitors and subscribers!
This material will discuss pros use of natural quarry stone, as well as its clutch like element facing portion structures without further delamination or destruction of the base.
Why preference is given to the stone more than other materials?
- The compressive strength of natural granite stone rubble is> 800 kg / sq. cm. (As a comparison, for the construction of foundations of private homes used concrete class B15-B25 with marks M200-M350 (200-350 kg / cm.).
- In view of the monolithic and very solid structure - Crushed stone is not subject to degradation from atmospheric precipitation. Such stone does not absorb moisture, and therefore the effect of freezing temperatures and reduced to zero. Also high durability!
- Stone - an environmentally friendly and aesthetically beautiful natural material which is unmatched by any single artificial element.
- Price rubble granite stone is from 600 rubles per tonne from the quarry (if expressed in cubic meters, in 1 cubic meter of stone - 1.4-1.8 tons).
Why with the time of the stone veneer is peeled from the base?
The first reason - the use of a narrowly-napilennogo stone, which is laid like tiles on grounds directly interacting with precipitation and temperature changes. This is the main cause of the problem, as no master stone cases do not advise to carry out work in such a way! Other reasons appear as a consequence of this basic problem:
- whatever special adhesives are not manufactured, stone, low porosity having a monolithic structure, is not capable of long time be in one fixed position under its own weight, and even more so under the influence of atmospheric precipitation in the open air;
- secondly, between the tiles laid stone has a seam, and no matter how good and strong this seam was not (visually may not be visible), it will still seeping water and may even accumulate in the voids of the adhesive composition. Detachment of stone begins with a "weak link" of the chain reaction went the one stone through time depart neighbors, etc.
There are professionals who are the main cause of detachment from the base of the stone called differential expansion of materials under the influence of weather conditions, which may also be true.
Of course, if the lining is made in such a way in a place protected from atmospheric precipitation - likely masonry last a long time!
Facing masonry rubble
Device facing masonry stone on the table facet - it's the only reliable option, which provides a long life stone structure. This masonry structure is made on a special or conventional cement-sand mortar in a ratio of 1: 3. In this embodiment, the stone turns out to pour into the overall design, and on all sides clamped solution. In prof.masterov even have one basic rule laying "Rule of three points of support." Stone in the masonry should not lie on your side, not on the edge, and stably and rigidly on its flat part 3 with the corresponding reference points subsequent ligation sutures stone.
