The length of life of masonry and concrete structures can be considerably prolonged if all types of humidity - e.g. rain, mist, condensation, ground water, river water and sea-water - are prevented from penetrating, because all harmful materials dissolved in the water have a disintegrating effect. Masonry is often porous whereas concrete can to a large extent be made compact. High quality compact concrete is capable of resisting mild attacks whereas most masonry and inferior-quality concrete has to be protected. If, however, the mild attacks are persistent protective measures should be taken in all cases. This report describes the most usual types of harmful agents and the materials used to combat them.
