I am looking for a some information in cutoff wall design. If anyone know some useful info on this, please let me know.

Thanks.

RE: Cutoff Wall Design

Could you be more specific as to what you are trying to cutoff, as well as parameters such as depth etc.?  If you are just looking for generic info, a Google search on cutoff walls yields a number of contractors who specialize in a wide variety of type of cutoff walls from plastic barriers to slurry walls.

Thanks Ctmtwilliam for your reply. I am looking to contain contain LNAPL (dielectric fluid) at a depth if 10 ft bgs. Is there any alternative for slurrywall like heavy plastic sheet?

RE: Cutoff Wall Design

I am not an expert on this matter but have looked into it for one of my jobs where we wanted to cutoff groundwater for a deep excavation. We are currently looking at using sheet pile with seals added in between sheets. You can either apply a compound (with a caulk gun type application)as you place sheets into the ground or buy special sheet piles that have a larger than normal opening betwee connections where a grout can be pumped into after placing sheets into the ground.

RE: Cutoff Wall Design

It is a common design to install vertical HDPE sheet in the slurry trench. As suggested by ctmtwilliams a google search will give you suppliers of proprietary systems and contractors.
