The paper is dedicated to the results of research on composite polymer material used for concrete casings repair. Field approbation of new material was carried out on the irrigation channel test site during the repair of concrete coating deformation joints and cracks. The paper provides the obtained theoretical formulae and results of water permeability calculation in concrete casing cracks with smooth and rough walls. A design chart for determining water permeability of damages in the form of cracks of various coating width on channel concrete coatings was obtained. A universal nomogram was obtained for determining the water permeability of damage in the form of cracks of various opening widths on the concrete coverings of channels.

In the presented materials, the physicochemical properties of composite polymer materials for protecting the root systems of forest seedlings from desiccation are studied. The conducted studies on the production of composite polymer materials allowed to establish their optimal ratios: the sodium salt carboxymethyl cellulose from 4 active substance wt.%, as target additives contains potassium chloride from 6.0 to 9.0 wt.% and ammonium nitrate from 0.004 to 0.006 wt.%. This ratio of target additives corresponds to the optimal relative viscosity of the composite polymer material equal to 170-175 s. Treatment of the root systems of seedlings with a composite polymer material allows not only to prevent desiccation, increase their establishment on the planting area, but also to reduce mechanical damage during transportation and forest planting.
