Even seemingly minor operations can contribute to the proper performance of the entire flooring system: the slight upturn of the polyethylene sheet, the overlaps of the welded wire mesh sheets, and the clear separations between concrete pour sections, as well as the use of structural polypropylene fibers, all ensure that the functions of the individual layers are carried out as effectively as possible.

In addition, choosing the “fresh-on-fresh” pouring method—where leveling the plastic concrete with a screed prevents the mix water from rising to the surface, which would otherwise seal the pores and impair the bonding capacity of the tile bedding layer—plays an important role.

Another option is to use a reinforced concrete sub-base treated with CEMENTQUARZ, an exclusive Mombrini product for adhesive (“glue-set”) tile installation. The anchoring of the reinforcement, shot blasting and/or milling are operations whose necessity will be assessed by our technicians.

Floor sealing

Floor sealing

It can be considered the most critical point of any flooring system, yet at the same time the strength of MOMBRINI’s technology. Eposystem (detailed technical datasheet available) is a three-component grout for acid-resistant joints in klinker or ceramic floors, designed to withstand the stresses of industrial environments. It consists of an epoxy resin base (comp. A), a specially formulated amine hardener (comp. B), and a multi-grain quartz filler mixed according to a distribution curve that ensures optimal compactness of the mixture.

Eposystem has the appearance of damp gray sand and can be applied with a 12 cm trowel in standard jointing (or with a special spatula for continuous joints). It hardens chemically within 6–8 hours with negligible shrinkage.

The careful analysis of variables—including the catalyst characteristics, the correct mixing of quartz grain sizes, the on-site preparation of the mixture, application by specialized workers, and finally cleaning using appropriate detergents and special machinery for rag preparation and flush-level joint finishing—summarizes a study that began in 1962 and is certainly still evolving.

The same considerations apply to sealing existing gaps between transition strips and the floor, between strips, between tiles and inspection covers, and also for manholes. The chemical-physical properties of the epoxy resin make it ideal even in the most aggressive conditions, making tiled floors highly durable in the areas most prone to infiltration, which are often the source of the most serious problems.
