Normally, hydrophobic treatments and coatings are selectively chosen to repair or protect different substrates depending on the climatic conditions, colour, change of initial aspect of the substrate, etc. The combination of these two different treatments in the same repair work is not normally considered. Recent investigations in different dispersion and impregnations technologies used and a combination of both in different products have been determined to work in synergy to give better results and permit the specific design of the work in each case according to the needs of a particular building or structure. This synergy between impregnations/patinas gave an optimal result in some singular buildings in Madrid. The concept is a toolbox of waterproofing/repair solutions to specifically design the best system on site, after laboratory screening tests. Keywords: impregnation, dispersion coating, hybrid, synergy. 1 Introduction Damage to various kinds of substrates always involves water. Water acts as a vehicle for transporting aggressive substances, such as chloride ions which are present in the water as it is drawn into the concrete by capillary action. Water
