What will happen to the foundation of the house if good drainage is not done

In almost all cases, the foundation of a house is built using concrete, and, as you know, it absorbs moisture perfectly. Constant exposure to water and temperature changes cause concrete destruction. Therefore, the foundation needs waterproofing, and in some cases the arrangement of the drainage system.

Drainage is used in the construction of houses on very wetlands. It is included in one of the stages of waterproofing the base of a building. In addition to the direct destructive effect of water on concrete, the foundation is damaged in the winter. When moisture freezes, the soil swells, which leads to fractures and deformations of strip and slab foundations. To prevent this, it is necessary to equip an annular drainage system around the house.

The common causes of poor foundation drainage are the wrong choice of waterproofing materials, errors in the construction of the system and its operation. This is indicated by a number of signs - the appearance of moisture on the lower parts of the walls of the house, increased humidity in the rooms, cracks, mold and fungus on the walls, crumbling concrete, skewed doors, and windows.

Disruptions to the drainage system occur when the depth of freezing of the soil and the occurrence of subsurface water are incorrectly determined. In such cases, the drainage simply does not have time to divert excess water.

A common mistake made when arranging drainage is its combination with storm sewers or a drainage system of the roof. A large amount of precipitation, especially in the spring and autumn, causes overflow of the drainage system. She ceases to cope with her task and allows a large amount of water to penetrate the foundation of the house. At the same time, the soil is waterlogged, and it becomes impossible to drain it.

Another error is caused by not observing the desired angle of inclination of the drainage pipelines or channels. This reduces the efficiency of the outflow of water from it, constant clogging and disruption of normal operation.

To restore the normal functioning of the foundation drainage, it is necessary to open the trenches in which the drainage pipes are laid. Rubble or gravel located in trenches must be washed or replaced. You may need additional sand bedding.

Flush the drain pipes as well. Damaged areas must be replaced with new ones. With insufficient efficiency of the system, stack pipes of increased cross-section. In this case, it is imperative to observe their bias, to ensure gravitational outflow of water.
