Opinions on the question of whether it is possible to fill the foundation in the rain are different. Some experts do not recommend doing this so that moisture does not accumulate. Others, on the contrary, talk about a slight effect on the strength of concrete, if you immediately cover everything with a film.
The arguments of experts
With the right approach to pouring the foundation of the future home, the question does not arise whether it is possible to fill the foundation in the rain. After all, multilayer falling asleep layers provides timely removal of moisture. At the very bottom is the soil on which sand is applied. Then rubble is crushed, which removes water well.
To understand whether it is possible to fill the foundation in the rain, it should be mentioned: the highest strength of the concrete base is achieved due to the duration of water removal from it. It freezes for several weeks. During this period, moisture gradually leaves concrete.
To obtain a solid base, water should not accumulate, nor should it come out very quickly. The drying process is optimal in humid ambient air, then the process is slow and optimal. And during rain, excess moisture is removed through a layer of crushed stone into the ground. Therefore, the quality of concrete should not be reduced theoretically.
Possible problems
There are several options when you can definitely answer the question: is it possible to fill the foundation in the rain. It all depends on the season of work, the type of future construction, strength and amount of rainfall. Too much rain will simply wash the poured solution. The formwork may dry out of it, and it will lead, which will ruin the conceived geometry of the base.
There is still a nuance when answering the question of whether it is possible to fill the foundation in the rain: if the surface of the base should be smooth, then drops of water will ruin the mixture. Roughness and pits may not appear when using shields made of solid materials. However, this will be too expensive a precaution.
Covering the surface of the foundation with a simple film in the rain, you can not guarantee the absence of marriage. Water will begin to accumulate in the folds of the material, which will lead to inaccuracies on the surface. This is unacceptable when the foundation being poured is the future floor of the room.
Possible future problems
It is important to distinguish whether it is possible to fill the foundation in the rain in summer or in the cold season. If in warm seasons the water is able to get out of it on its own, then with frost it can remain inside. Excessive fluid after heavy rainfall may partially block inside the base. It happens so that the concrete is already set, and inside there are still areas with watery inclusions.
The described case leads to a weakening of the structure, shells with liquid are formed, subsequently remaining empty. The foundation may crack in these places in the future. To exclude marriage, you will have to mix the concrete until the end of the rain. But if this procedure is too long, the foundation will already have air shells.
Similar problems are observed when water freezes inside the foundation. It begins to expand, leading to a defective base. Void necessarily appear in the future in a year or several years. The load capacity is significantly reduced from the calculated.
But to answer the question of whether it is possible to fill the foundation after rain, it turns out simply: if the formwork remains unharmed and there is no sign of its destruction, the concrete is laid perfectly. It is recommended to pay attention to the accumulation of water: there should not be puddles in the base. If liquid is not drained, measures should be taken to change the construction of the foundation.
Construction goals
When answering the question of whether it is possible to fill the foundation during rain, it is important to determine the features of its use. For many utility rooms with minimal requirements, the quality of the base does not require a flat surface. The load can be low due to the use of gas blocks.
The foundation is distinguished by the type of execution: tape, monolithic, solid. In the first method, rain, even heavy, does not threaten the deterioration of concrete quality. Moisture will quickly drain into the ground. In the second method of pouring, there is a risk of stagnation of water - this will not have a good effect on the quality of the mixture. The sand will begin to wash out and rise up.
Recommendations
Getting a quality foundation is a long process, and technology should be followed exactly. In hot weather, you have to force-pour concrete mixture for several days. It does not have to be covered from rain, but from burning sun rays. Such a measure is necessary to eliminate cracks in the upper layer.
The strength of concrete is gained for a period of at least a month. Throughout this period, both the hot time and the prolonged downpours are unfavorable for him. You also need to keep within before the start of frost, so that the destruction does not occur from the inside.
If important work is required to fill the foundation during heavy rains, then cement with a brand name of at least M500 is used. This material has a higher cost, but is able to solidify at high humidity.
Additional Information
Air and water shells in the mixture during pouring are removed with a special vibrating tip. It is advisable to use with any type of foundation. The latter is required to be covered immediately after excess moisture has come out.
Complex foundation forms with significant depth should be performed in the absence of rain to prevent moisture accumulation. It is necessary to take into account the change of seasons when the rise of groundwater is possible. This happens more often when snow melts.
