Steel and reinforced concrete marine piles can deteriorate over time due to the corrosive marine environment eroding the structural strength of the piles, severe cases can occur with total loss of structural capacity compromising the life span of the structures they support.
Fabric formed concrete can protect, repair or strengthen piles through encasement in high quality concrete. Especially suited to projects where underwater installation is required, the repairs can be designed for medium to long-term protection prolong the lifespan of jetties and marine structures.
The porous formwork causes the sand & cement micro concrete mix to bleed down to a water:cement ratio approaching 0.4. This gives a significant improvement in durability against carbonation and chloride ion penetration. Steel reinforcement can be included for strengthening where required.
Marine growth and spalled concrete are removed, and the piles cleaned back to bright steel, typically using high pressure water jetting.
