Ever-greater importance is being attached to sealing concrete structures. Although construction joints are unavoidable in structural components for design and practical reasons, the damage that is often coused by moisture at such locations can be avoided. The extent of work and costs associated with remedial work are high. The growing awareness of quality and durability calls for new design solutions that guarantee long-term protection against penetration.
