Extensive repairs and targeted upgrades for the sanitation infrastructure of Rio das Ostras, on the Atlantic Coast of Brazil, was completed in March 2023. Further upgrades and repairs continue to be made across multiple communities in the region. The specification of the Penetron System of concrete waterproofing and repair products ensures the durability of these repaired concrete structures.

A Brazilian city of over 155,000, Rio das Ostras is located 160 km (100 miles) east of Rio de Janeiro on the Atlantic Ocean. Home to public and private schools for primary and secondary education, Rio das Ostras also has many universities: Universidade Federal Fluminense (UFF), Universidade Unigranrio, and Universidade Estácio de Sá. Popular attractions include Joana Beach, Ostras River, and Mirante da Praca da Baleia.

“The rejuvenation and upgrading of the local sanitation infrastructure has become urgent,” explains Cláudio Neves Ourives, CEO and Managing Partner of Penetron Brazil. “The completion of the Rio das Ostras project is a big step towards alleviating the dangerous levels of pollution prevalent in the rivers, beaches, and lagoons.”

BRK Ambiental, a water and sanitation engineering company in charge of the Rio das Ostras project, specified a combination of Penetron System products for the repair of the existing sanitation infrastructure:

  • PENETRON CR-90 – a single component, polymer-modified repair mortar for worn, spalled, and distressed surfaces

  • SURFIX BLEND PATCH (i.e., PATCHLINE) – a fast-setting, cement-based, one-component concrete and masonry patching material

  • PENETRON ARC – an active mineral protective coating specifically formulated for anaerobic conditions

The Penetron Brazil technical support team monitored the application of the topical Penetron repair materials by Concrejato, the Penetron-approved concrete repair team.

“Applying the Penetron System to the damaged sanitation infrastructure at Rio das Ostras has eliminated the previous sources of concrete deterioration – and will help make the waters of Guanabara Bay cleaner,” concludes Cláudio Neves Ourives. “Proven around the world in similar concrete repair projects, the Penetron System plays a key role in the waterproofing and protection of concrete structures exposed to aggressive environments.”
