Scientific and practical significance

Traditional approach

Selection of external waterproofing by water type and structure

The protective layer is evaluated, but concrete self-restoration is not considered

Materials-science approach

Testing concrete with admixtures for permeability and strength

Provides material properties, but does not link them with foundation technology

Proposed approach

Joint assessment of concrete, crystalline admixture, joints, drainage and life-cycle cost

Allows alternatives to be compared using an integral index and weak criteria to be identified

Novelty element

Introduction of a self-healing criterion into the model for selecting foundation waterproofing

Accounts for restoration of watertightness after microcracking

Practical result

Tabular calculation and graphical interpretation of alternatives

Creates a basis for design justification of the selected solution
