  Hi all,

I am designing drilled piers and driven piles foundation system for a bridge. There are some thin strata (less than 300mm thick) of gypsum within the sound bedrock. Though the pier will be penetrated at least 3m into the sound bedrock, should I be concerned with gypsum layers on the sides and any layers below the bearing surface.

Thanks
