The foundation is the underground part of the structure, which takes on all the main load and transfers it to the ground. And any mistake at the stage of calculations or construction will sooner or later destroy the entire house. In the case of a strip foundation, this is especially true, because it is located directly under the walls and load-bearing partitions of the house. That is, it completely repeats its contours. Mistake number one: Building a foundation without a professional calculation. By eye, as our grandfathers built. At best, with a stretched string and a plan of the future house scratched on a napkin. Or even "by eye", because the foreman built exactly the same foundation in the neighboring SNT. Don't be surprised, in the 21st century there are plenty of people who will easily risk a couple of million to save on a quality project. And then they tell stories about clumsy builders who poured the strip foundation incorrectly. By the way, if you made an architectural project, it will not work either. Since it does not contain complete information about the technological units and does not contain calculations. And construction without calculations is like Russian roulette with a full clip. The second mistake - Geology is not taken into account. That is, the builders did not care about the properties of the soil, the level of groundwater and the depth of soil freezing. As a result, the foundation cracks, subsides, floats or explodes after the first winter. Mistake No. 3. Unfortunately, not everyone removes the fertile soil layer before digging trenches. Yes. This saves you a little time and budget, but know that such a layer contains a lot of organic matter. Over time, all this will safely rot and shrink under the foundation. As a result, you will get uneven subsidence of the soil and, accordingly, cracks in the walls. Therefore, we prepare the pit and trenches correctly and do not save on excavation work. Mistake #4 - Universal, applies to both customers and builders. Using cheaper building materials than required by the site. For example: • cheap cement • Too much water in concrete • Some especially gifted developers manage to mix concrete with soil. Big deal, the formwork cracked, why waste it! • Someone manages to use smaller diameter reinforcement when making a metal frame. Someone even looks for the cheapest wire for tying. In general, there are many ways to save money, but they all have sad consequences. Mistake #5 - It is strictly forbidden to make basements, cellars, and any other depressions near the foundation, unless this is provided for by the project! In this case, the soil will be squeezed out towards the undermining, and the worst consequence of this is collapse. Always strictly follow the project, specialists have already taken into account all the features to avoid such mistakes. Mistake #6 - Absence or poor-quality backfill of the sand cushion. The cushion is needed to relieve the pressure from frost heaving from the foundation. If there is clay or sandy loam on the site, then it must be removed and replaced with a non-heaving layer of sand. Some do not do this at all, some use sand mixed with the same clay, which greatly reduces the efficiency. And in order to properly tamp the cushion, you need a vibrating plate and tamp it layer by layer, in several stages. As a rule, builders do not like to bother so much. Mistake #7 - We rushed and removed the formwork too early, and as a result, the concrete did not gain sufficient strength. It seems that there is nothing to worry about, but no - this leads to the destruction of the structure itself. Sometimes the formwork simply breaks under the pressure of the poured concrete. This happens to inexperienced or overly thrifty builders who saved on fasteners. Mistake #8 - Too much reinforcement. Here we are talking about the fact that some future homeowners once read somewhere that the more iron in the foundation, the better, so they put everything they can get their hands on into the solution. No, friends, you can't do that. Of course, reinforcement is needed, but there are clear rules for its installation: the rods should only go from the bottom, in the middle and on top. The reinforcement should be placed horizontally, along the entire strip of the solution pouring. And you should not throw it on the ground or on the bottom of the formwork, you need to maintain a protective layer of 30-60 mm. Otherwise, over time it will be useless, will not perceive tensile loads. Watch this video: • STRIP foundation TOP-11 mistakes p... ➤ Our website: https://buildup.ru/
