Is it possible to pour concrete in the rain during the

The service life of the entire building depends on the reliability of the foundation; therefore, when working on the laying, the technology must be strictly observed. Along with this, options for performing operations under difficult weather conditions should be considered. For example, not everyone knows that improper concrete pouring during rain can affect the strength characteristics of a foundation.

Key points

In fact, the cool and damp weather is great for creating the foundation for any structure, which is associated with high-quality solidification of the composition used. In the course of work, all you need to do is to ensure that an excessive amount of water does not fall into the finished solution.

Below are some techniques that will help you understand how concrete is poured in the rain.

• The use of polyethylene film or any other waterproofing material will protect the mixture from water ingress.. In this case, the protective membrane must completely cover the formwork and the tank with the composition.
• The use of high-grade cement makes it possible to improve the moisture resistance of the finished solution used in the work. To work with precipitation you will need a binder M400 and above.
• The use of vibration equipment helps protect the structure of reinforced concrete from the occurrence of internal voids. Monolithic mass will be the highest quality.

Question! Is it possible to concrete the foundation for the structure in the rain? Under certain conditions, work is possible. However, in case of heavy precipitation it is better to refrain from carrying out construction operations of this type.

Performance of work

To lay the foundation with your own hands during a light rain, you need to familiarize yourself with all the stages of construction, as well as consider the materials and equipment used. After the preparatory measures, you can begin the process of concreting.

Necessary tools and devices

• Container for mixing the mortar or directly the concrete mixer. In the second case, the quality of the composition will be much higher.
• Polyethylene film will be required to cover the formwork and create a place for mixture preparation.
• Vibrating unit is needed to compact the mass. With it, the strength characteristics of the base will increase, as excess moisture will be removed.
• A bucket is needed to deliver the mix, especially if there is no concrete mixer on hand.

Preparation of the solution

An important role is played by the quality of the kneaded mixture when working in the rain, so attention should be paid to this factor.

It is necessary to carry out preparation from high-grade cement, due to which it will be possible to improve the resistance to moisture.

1. Before preparing the composition, a canopy of boards and films is arranged so that excess moisture does not get into the container.
2. One share of M400 cement is taken and poured directly into the installed container for mixing.
3. 1.9 shares of quarry or river sand are added there, after which dry mixing is performed.
4. Next, water is added, the amount of which is usually 0.5 mass of binder. With precipitation its weight can be slightly reduced.
5. 3.7 fractions of aggregate in the form of gravel are introduced into the solution.

Attention! This way it is possible to obtain a concrete composition of class B22.5. It is able to withstand at least 302 kgf / cm ?, therefore the bases are distinguished by high strength.

Pouring process

When working, it is necessary to take into account not only the nuances of the mixture preparation, but also the correct implementation of the tab. If the height of the foundation is high enough, it is advisable to perform the installation continuously using vibration equipment.

The price of such units is quite high, but after compaction the quality of concrete improves to a great extent.

1. A waterproofing layer is laid in the pre-fabricated formwork, which on the lower side will prevent contact with a moist environment.
2. Inside the structure is placed a reinforcing grid of metal rods, the elements of which are fastened together with wire or welding. At the same time the distance from the edges should not be less than 5 cm.
3. Polyethylene film is cut into strips. The width of the fragments is determined by the thickness of the foundation with a margin of several centimeters. All formwork is temporarily closed.
4. At one of the sites the film is removed, and in the inner part the composition is laid. It is recommended to tighten the area where the work is not done.

Note! If concrete is poured in - and it began to rain even more, then the formwork must be securely closed with a film so that water does not get inside. If necessary, the membrane is placed in two layers.

Additional operations

After a few days, when the composition is well grabbed, you can remove the film and engage in other actions. If no holes were made at the base, then diamond drilling of the holes in the concrete should be carried out. This will help protect the space under the floor from mold.

Sometimes it may be necessary to separate a small segment from the base. In this case, reinforced concrete is cut with diamond circles. This is done mainly in connection with communications.

Приведенная инструкция направлена на то, чтобы помочь индивидуальным застройщикам провести фундаментные работы при небольших атмосферных осадках. В сильный ливень производить заливку не рекомендуется, так как качество основания может сильно пострадать (см.также статью «Заливка бетона в мороз: основные проблемы зимнего строительства и особенности их решения»).
