HDPE sheet pile wall
HDPE sheet pile wall
(OP)
I am currently looking at a site where a cut-off wall needs to be installed with Permeable Reactive Barrier gates. The groundwater has very low PH's and has a high salinity. The use of galvanized steel sheeting is the way we are looking to go based on a 30 yr design life. Does anyone have any information or can point me in a direction to learn more about HDPE sheet pile walls or PVC sheet pile walls. I am trying to figure out if they are a cost effective alternative to the standard stell sheeting.
Thanks

We ended up using it as a cutoff wall within the core of a detention control structure. It seemed to work out OK, but I think it created a slip surface within the soft clay.
It drove fairly easily and it was more cost-effective than steel sheeting.

I would be concerned about galvinized sheet piling. As you drive it you will scrape much of it off. Corrosion in those areas will actually be accelerated and despite the money, you probably won't get significant corrosion protection. Two other options are using Mariner grade sheet piling or using precast concrete sheetpiles.
