Maldives
A repair and protection concept had to be developed for several hotel villas built on concrete stilts, as well as a pier, at a holiday resort in the Maldives. The client and planner relied on the expertise of MC-Bauchemie to ensure the long-term safety of the buildings under extreme climatic conditions.

Some of the villas, built on concrete stilts in 2016 at a luxury resort on the Baa Atoll in the Maldives, had begun to show signs of damage due to exposure to chlorides from seawater. After the resort was acquired by a German owner in 2019, a Hamburg-based engineering firm was commissioned to investigate the structural integrity of the buildings. The goal was to design the repairs in a way that would prevent future damage from the aggressive sea climate, ensuring the villas would remain usable in the long term. The engineering firm involved MC-Bauchemie early in the planning stages to develop tailored solutions for the unique climatic and infrastructural conditions. The project timeline spanned from April 2022 to December 2024, with the renovation works being carried out during ongoing hotel operations.
The project was marked by a range of technical and logistical challenges. One of the largest was the geographical remoteness of the resort. All construction materials had to be transported by sea to the Maldives – careful planning of the required quantities was crucial, as resupply would have been costly and complicated. The climatic conditions, particularly the high chloride concentration in the seawater, also posed a challenge. Additionally, the existing structure had been treated with unknown materials, some of which no longer met modern standards.
Together with MC, the engineering firm developed a customised concept for repairing the concrete damage and ensuring the long-term stability of the load-bearing structures. The construction company Isebarth GmbH from Hannover took the lead in implementing the project, training local workers along the way. First, the old coating was removed from the undersides of the water villas to expose the damaged concrete surfaces. Then, cracks and damaged areas were repaired and reprofiled using MC’s Nafufill repair mortars. For surface protection and sealing, a specially adapted variant of MC-Proof Eco was used, both in manual and spray applications. The reactive sealant impressed with excellent application properties, quick reworkability, high crack-bridging capacity and UV resistance.
Other products, such as the moisture-resistant and crack-bridging roller coating MC-DUR Top- Speed Flex and the injection resin MC-Fastpack 1264 compact, ensured quick and efficient sealing and reinforcement of the components. In total, approximately 167 tonnes of material were transported – a logistical feat that would not have been possible without the precise planning and collaboration of all parties involved.
Thanks to the use of MC products, the first phase of the construction was successfully completed, ensuring the operation of the water villas for the coming years. Due to the positive results, the contract was extended to include the renovation of the pier, and MC’s product systems will now also be applied as preventive concrete protection across two new construction phases.
