  • End result of the renovated pier in bonaire

    In 2018, Bouwcombinatie Bonaire commissioned SealteQ to renovate the southern pier in Kralendijk in Bonaire in an innovative way. Over the years, the pier had been heavily affected by the salty climate (corrosion of reinforcement). The pier has been completely renovated as a result of SealteQ's extended maintenance measures. This was the first project on which large-scale glass and carbon fiber reinforced polymer were applied, with an attractive end result. Glass and carbon reinforcement are insensitive to corrosion due to the salty environment. As a result of this work, the lifespan of the pier has been extended for a period of 30 - 40 years.
