Quality foundation is a guarantee of durability and strength of the future structure. That is why it is important to prepare the correct concrete solution and not save on the price of concrete for the foundation in Odessa. It should include the following components:
Cement.
Water.
Gravel.
Sand.
As for the proportions, they should be as follows: 10 kilograms of cement, 30 kilograms of sand, as well as 50 kilograms of gravel. The amount of water is recommended to select individually. If the solution is excessively dense, then you can add liquids. It is advisable to observe the consistency so that the solution is easily stirred with a shovel or other tool.
Useful tips
During work, it is necessary to take into account the fact that moisture may be present in raw sand. To avoid problems, it is recommended to dry it or use a smaller volume of water. It does not hurt to check how clean the sand is. Naturally, the better it is, the more efficiently grasp the solution.
A good choice will be small gravel (one or two centimeters). No need to buy cement long before the start of construction work. The material is able to instantly absorb moisture, which will worsen its quality. Purchase cement about a week before the start.
The optimal period for the formation of the foundation is considered spring-summer. If the street is cool, then the builders will have to regularly heat water and solution. Otherwise, he will seize much earlier than the due date.
It is important to calculate in advance how much concrete is necessary for a specific foundation. The most difficult to create is the strip. All lines (tapes) must be calculated separately, and then add the resulting value.
Having prepared a solution for the foundation, it must be poured into the formwork. As practice shows, this must be done in layers. For example, if the height of the foundation is one meter, then you will have to concrete four layers of twenty -five centimeters. In the process of filling the layers, they need to be rammed. Additionally, it is necessary to release air. This is done as follows: every one or three meters you need to walk next to the foundation and drive the reinforcement into the solution.
All layers of concrete are recommended to align. For this purpose, you can use an ordinary board. However, it should be absolutely even.
