Seawater had penetrated the structure completely, with water forming within the small air pockets found throughout the structure. The internal walls were also rotting and were continuously wet throughout the winter months. After trials were conducted with several products, it was found that the only suitable solution was Chemco.
The lighthouse had to be encapsulated due to the harsh weather conditions found next to the coast and to stop further water ingress. The encapsulation also ensured that no debris from the surface preparation procedures would contaminate the sea.
All external cracks were opened up; resulting in the release of water held within the walls. Abrasive blasting was utilised as the surface preparation method.
One primer coat of Damp-crete™ RH 800 was applied over the entire concrete structure. All holes and cracks were then filled with Chem-concrete™ RI 800CRS. One coat of solvent-free, wet tolerant epoxy Epo-chem™ RA 500M was then applied as an impermeable barrier before one high gloss topcoat of Fast-guard™ RN 500TC was applied.
The project was completed within the given time-frame and to the complete satisfaction of all parties involved.
