Any blocks purchased directly from us have not been used before, as we do not offer re-sale products, however if using older blocks from existing sites or buying elsewhere, please check the lifting pin for wear or corrosion, prior to lifting and check the block for any cracks.
If the block is cracked or the pin is worn, it could fail when being lifted.
Choose our precast concrete kentledge blocks for a reliable, adaptable and sustainable solution to your stability needs.
