Waterproofing of parking garage structures with sealers and membranes: the Canadian experience

The investigation of factors affecting the water impermeability of inorganic sodium silicate-based concrete sealers

“…Concrete sealers belonging to the same generic type were often found to have quite different waterproofing performance, generally resulting from the different concentrations of the active ingredient [28]. This is because the concentration of the active reactant not only determines the quantities of the product but also directly affects the gelation time of the sealers.…”

Water Vapor Transmission and Waterproofing Performance of Concrete Sealer and Coating Systems

“…Soudki et al (2012) also observed that sealers and coatings significantly reduced the penetration of water and chloride ions into concrete. An appropriate surface coating system can protect concrete structures from corrosion and de-icing salt damage by inhibiting the penetration of chloride-laden water (Litvan 1996;Palle, Hopwood II 2006). In contrast, it has been shown that penetrating sealers are not as effective as surface coatings in improving the scaling and corrosion resistances of concrete (Ibrahim et al 1999;Litvan 1996;Wenzlick 2007).…”

However, the performance of penetrating sealer can be improved by an over-coat application of a surface sealer or coating (Ibrahim et al 1999).…”

The Methods for Creating a Waterborne Saline-Based Hydrophobic Agent for Waterproofing Use

“…It is well recognized that the main components of the most commonly used hydrophobic agents are alkiltrialkoxisilane, alkilalkoxisiloxanes or a mixture of these two components [19][20][21][22]. Furthermore, alkiltrialkoxisilane-based hydrophobic agents is generally found to penetrate deeper in the concrete substrate than talkilalkoxisiloxane-based hydrophobic agents [20,22], but the former agents are more volatile than the latter ones [20].…”

In addition, waterborne systems (micro-emulsion) [3,19,23] is increasingly becoming popular because of environmental protection.…”
