The paper presents the results of investigation carried out using the method of optical high-resolution microscopy of the morphology and structure of waterproofing membrane coatings based on polyurethane isocyanate, alkyl phenol-formaldehyde resin and dibutyl dilaurin olovas with finely dispersed oxide fillers and fine solid waste of aluminum industry. When obtaining polymer composites (films), the ratio of the main components of the polymer matrix - urethane isocyanate and phenol-formaldehyde resin was varied as well as the composition of fillers. The homogeneity of the obtained films and their structure, as well as the aggregate ability and uniformity of the distribution of powdered iron oxide fillers and fine solid waste in the volume of the polymer matrix were investigated in the modes of light field, phase contrast and crossed nicols. The resulting composite materials in the form of film coatings, as well as adhesive or repair composition can be used for waterproofing and repair of building structures.
