On Tuesday 15th February 2022, the European Concrete Pavement Association (EUPAVE) held a technical webinar entitled “Enhancing Concrete Durability”, which focused on different types of protection systems for concrete surfaces.
Mr. Luc Rens, Managing-Director-EUPAVE, opened the event by welcoming the participants and presenting EUPAVE and its activities. Luc also outlined the context of surface protection products, both in Europe with the EN 1504-2 standard and on the basis of an American classification of “penetrating sealers”.
Presentation:
Introduction
Mr. Michael E. Ayers, President-Global Pavement Consultants, Inc. and Mr. Radi Al-Rashed, President & CEO-International Chem-Crete Co. started by presenting Chem-Crete and its waterproofing technologies. They specifically focused on two of their products: the topically applied PAVIX CCC-100, a dual crystalline “sealer”, and MCE, an intermixed multi-crystalline enhancer. A large amount of information from laboratory testing and field trials was presented.
Mr. Oleg Tataru, Head of Aerodrome Service, Moldova presented the work done at the Chisinau International Airport.
Presentation:
“Pavement Preservation and Sustainability Benefits of Using Dual and Multi-Crystalline Technologies“
Mrs. Sylvie Smets, Researcher and Technology Advisor-Belgian Road Research Centre explained the “Influence of hydrophobic impregnation on resistance of road concrete to de-icing salt“. She started with a quick introduction and presented laboratory results, results from on-site samples and the effect of curing and aging of the concrete on the scaling resistance of the surface.

The event closed with a Q&A and conclusion remarks by Luc Rens: “In specific situations, e.g. concrete with no air entrainer, and for specific applications e.g. airfields, the use of surface protection systems are definitely recommended. They are able to significantly improve the quality of the concrete surface and to extend the service-life of the pavement. However, the use of a penetrating sealer should never be a pretext for a lesser quality concrete!”
