ABSTRACT:
A method of driving composite timber pile sections provides a pair of timber pile sections, the first of which is driven into the earth a distance leaving the butt of the pile exposed. A splice element is embedded into the remaining pile section and leveling material is added to the top of the first pile section. Upon assembly and during driving, the leveling material is laterally confined with the splice element while the respective mating surfaces of the two pile sections confine the leveling material vertically with the leveling material thus transferring compressive load between the two pile sections. In the preferred embodiment the splice element is a cylindrical element having a hollow inner bore which during operation contains the leveling material. An initially displaceable but later setting, non-displaceable material such as mortar (a mixture of cement, sand and water) could be used as the leveling material.
