which is an appropriate layering process for a composite pile
1. Start by driving or drilling the primary pile into the ground to the desired depth.
2. Insert the secondary pile into the primary pile, ensuring that there is a tight fit between the two piles.
3. Pour concrete or grout into the space between the primary and secondary piles to create a strong bond.
4. Repeat the process for additional layers of piles, if needed.
5. Finish by capping the top of the composite pile with a pile cap or header beam to distribute the load evenly across all layers.
