What diameter and length Pearson Pile should I use for a house foundation?
The length and size is entirely dependent upon the load requirements, pile spacing, soil conditions and height above grade. Very few states have building codes for foundations, so it is important to have your architect or structural engineer determine the appropriate piles. We can recommend some foundation brackets and help with the beam to pile attachment in terms of design with your architect or engineer. The land in which we will be building on is shallow soil with lava rock just beneath at a depth of 5ft+-. I will be ordering a soils report to obtain a more accurate status. Do you know if that would prevent or cause some issue on how the Pearson pilings are driven into the ground as well as minimum depth level? It sounds like you will have good bearing capacity from the lava rock, but I would have some concerns about uplift (this would be true with any piling material). One way to increase uplift capacity is with earth nails or dwydag rods and washers into a drilled hole – this can
