Which provides better support cased or uncased

Sorry for the delay. No one monitoring. Uncased is less $ than cased as the addition of PVC and Steel adds expense. Cased has a smooth surface so you don't pick up any friction component and added capacity as you do with the corrugated, rough surface of the uncased pile. So uncased is first choice. However, if you can not guarantee the integrity of the grout column ( in water or above grade as examples) then you have to go with the cased pile. Here is a link to some case studies showing both cased and uncased piles. www.danbro.com/portfolio-tags/grouted-helical-micropile/ If you scroll down to the 7th row, you will see a pic of an unearthed uncased pile with the corrugated/rough surface. If you have further questions, you can call (609-675-4592) or email ([e-mail]. Thanks for your interest
