Features of waterproofing of agricultural buildings and structures
High groundwater levels, defects and imperfect drainage systems contribute to the active dampening of stone structures, resulting in their corrosion destruction and accelerated load loss. There are two main sources of capillary pull-up: groundwater level and so-called sprayed water. Analysis of the destruction of stone buildings shows that the major factor in their destruction is the various sources of excessive soaking (up to 50% of buildings) and, as a consequence, salinization. High groundwater levels, defects and imperfect drainage systems contribute to the active dampening of stone structures, resulting in their corrosion destruction and accelerated load loss. There are two main sources of capillary pull-up: ground water and so-called sprayed water. The humidity decreases in the bottom-up direction, as well as from the middle of the wall to its outer surfaces, which means that the capillary suction of water is in effect. Analysis of the destruction of stone buildings shows that the major factor in their destruction is the various sources of excessive soaking (up to 50% of buildings) and, as a consequence, salinization. Waterproofing has a huge impact on the durability, comfort, and cost of operating the facilities. The lack of waterproofing or its destruction, as well as the violation of the wet regime, are the cause of many defects in both individual structures and buildings in general, which require considerable cost. In the case of insulation failure or lack thereof, the soil water seeps through the walls and destroys the plaster and masonry from the outside, and after the capillary movement inside the masonry, reaches the inner layer of the plaster. Depending on the degree of threat, the appropriate type of waterproofing should be used. The quality and durability of the waterproofing layer depend on the strength of the surface preparation. Reliable adhesion to the substrate, solid coating and uniform thickness of the waterproofing coating are ensured by quality alignment, cleaning, drying, priming of the insulated surface, as well as careful preparation and execution of joints, touches and seams. To protect the foundations, walls and columns of agricultural buildings and structures from the capillary rise of moisture, we propose to cut off the inter-wall waterproofing and improve the hydrogeological conditions of the site. Waterproofing materials must comply with European standards and be certified by ISO quality management system.
