  Hi all,

I am designing drilled piers and driven piles foundation system for a bridge. There are some lenses and 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 sides and any layers below the bearing surface. Any info/advice will be appreciated.

Thanks
