Barrettes or strip piles are the best alternative where a single pile safe working load in excess of 3000 tons is required or conventional bored piling is impractical. Various dimensions, cross- sections and orientation can be formed and arranged to suit design requirements. SEAFCO’s barrettes are used in foundation for expressways, transmission towers, MRTA subway stations and high rise buildings. Barrettes can be constructed to a depth of 60m or deeper.
