Flexcrete solution helps bridge cracks

September 2017

In response to customer demand, Flexcrete Technologies of the UK has launched a new elastomeric, intermediate crack-bridging filler and coating for use on concrete structures and buildings where enhanced cracking-bridging properties are required.

Supplied as a readymixed paste for ease of use, Monodex ICB is highly cost effective as it does not require the use of substrate or inter-laying priming. It is designed for use in conjunction with Flexcrete’s Monodex anti-carbonation membranes and is capable of bridging existing cracks up to 1 mm underneath the coating.

Commenting on the new product, Flexcrete director Chris Lloyd says: “Several of our customers were seeking an economical product that is able to bridge cracks and fill pores, cavities and blowholes prior to the application of our Monodex coatings. Traditionally, reinforcing tape would have been incorporated to bridge cracks in these instances, but Monodex ICB removes the need for any type of reinforcement and it is very quick and easy to apply by trowel, or by roller or spray when diluted with water.

According to him, another advantage of Monodex ICB is that it is rapid-curing and used as part of a three-coat system in conjunction with Flexcrete’s Monodex anti-carbonation coatings. “Alternative products require the use of primers and multiple other coats, but Monodex ICB is applied directly to the substrate which makes it an economical and time-efficient option. It ensures enhanced performance of the complete Flexcrete system and even greater anti-carbonation protection as Monodex ICB itself has excellent anti-carbonation properties,” Lloyd adds.

As Monodex ICB is water-based, it has minimal VOC (volatile organic compound) levels and releases ultra-low odour during application, making it ideal for use in sensitive or enclosed environments, he says.
