Conclusions

  1. 1.

    Laboratory and full-scale investigations showed the possibility of using coatings of epoxy-coal tar foamed plastic for insulation-waterproofing of hydraulic structures in regions with a rigorous climate.

  2. 2.

    It was established that in the case of the same insulating effect the insulation-waterproofing of epoxycoal tar foamed plastics is one of the most economical in the construction of structures by any method.

  3. 3.

    For zones of a variable water level, on structures not subjected to the effect of ice, insulation-water-proofing with a protective enclosure of glass-reinforced plastic can be recommended. Under constant ice conditions it is necessary to use coatings with a sheet-metal enclosure.

  4. 4.

    In connection with the increased shrinkage of the epoxy-coal tar foamed plastics the thickness of coatings on their base should not exceed 5cm. It is necessary to continue the search for cheap foamed epoxies not having a high shrinkage.
