Comment

High groundwater level

High-watertightness concrete + crystalline admixture + external waterproofing + drainage

the system should include at least two independent barriers

Risk of temperature and shrinkage cracks

Self-healing concrete + crack-width control

crack resistance calculation is mandatory

Large number of construction joints

Crystalline admixture + waterstops + injection hoses

special attention should be paid to concreting joints

Aggressive groundwater

Crystalline admixture + anti-corrosion protection + concrete mix selection

requirements for corrosion protection must be considered

High repair cost after commissioning

Integrated system A3

life-cycle cost assessment is necessary
