Twelve toe grouted, and eleven ungrouted piles, founded in very dense sands have been analysed to establish how toe grouting enhances pile performance. It is shown that pile stiffness is greatly increased, and that pile bases work effectively. This is in contrast to ungrouted piles, where some milliĀ­meters of base movement may be required before the base is mobilised. Grouting appears to recover most of the disturbance caused during construcĀ­tion, but in general does not enhance the ultimate bearing capacity of undisturbed ground.
