METHOD FOR INSTALLING A WATERPROOFING COATING Russian patent published in 2023 - IPC E04B1/64 

FIELD: construction.

SUBSTANCE: used in the construction of waterproofing coatings made of polymeric materials, both for stand-alone underground buildings and structures for civil, industrial and transport purposes in general, and for individual units, structures, elements of underground parts of the building system, structure. The technical result is achieved by the method for installing a waterproofing coating, including laying on the base a coating layer consisting of epoxy resin, “ЭТАЛ-45М” hardener. Preliminarily, dirt is mechanically removed from the base and dust is removed, then sequential laying on the base of at least two layers of the coating is carried out, composition is laid as the first layer, at a ratio of components, wt.%: epoxy resin 40-45%, hardener “ЭТАЛ-45М” 40-45%, petroleum coke ash 10-20%, epoxy resin “ЭД 20” or “ЭД 249” is used as an epoxy resin, in a volume of 0.003 m³ of the composition per 1 m² of the base area for each layer, glass fabric is laid as the second layer, while the size of the glass fabric corresponds to the size of the base, then the glass fabric is rolled with a spiked roller or pass with a spatula to impregnate fiberglass, then carry out a process exposure for a duration of 0.5 hours, while the maximum number of stacked layers is six.

EFFECT: creation of a simple and effective method for constructing a waterproofing coating by forming a durable coating resistant to alternating loads with a wide curing temperature range from -5 to +35°C, low thixotropy and heat resistance up to 135°C, as well as the expansion of production capabilities.
