Evaluation of Waterproofing Systems’s Adhesive Strength

Hydrophobization of the surface of the structural material is an effective type of protection of concrete of underground constructions from moistening and damage by water solutions containing aggressive chemical substances. As a rule, the insulation system includes waterproofing material as well as intermediate layer materials. An important factor of durability of the insulation system is the joint work of each of its elements and the base material. The purpose of the research described in the article was the development of methods to optimize the technology of arrangement of repair of waterproofing coatings of underground structures. The research is based on the methodology of determining the adhesive strength of waterproofing coating, based on the determination of the adhesion force at the detachment of insulation layers. The algebraic model of dependence of adhesive strength of waterproofing material on the composition of modified binder and moisture content of the base surface has been developed and its experimental verification has been carried out. The influence of the roughness and cracking of the sedimentation surface on the waterproofing coating has been evaluated. The values of parameters determining the optimum strength characteristics have been established.
