Concrete Manhole Liner H2S
Concrete Manhole Liner H2S
(OP)
Has anyone come in contact with manholes that they have had to coat do to a H2S problem. I even have the riser gaskets coming out. If so, has the material/s been tried and reviewed for more than 5 years? I have read that some are failing after a few years. The manhole is 21' deep and has a 48" diameter. The water table is about 10' from the bottom. Liner? Spray-ons? Tensile or flexural properties more important?

1. Sauereisen Sewergard Lining No. 210 with Sauereisen Underlayment No. F-120 or Sauereisen Underlayment No. F-120C
2. Sewer Shield 100 Epoxy Lining or Sewer Shield 101S Epoxy Lining with C120 calcium aluminate cement underlayment

It's appropriate for existing manholes, once you've chipped down to sound material, repaired any structural damage and tested the substrate. The two that cvg mentions can be sprayed or troweled on.

I was looking at Raven Linings. But, it seems that they have had problems in the pass!
Does anyone have experiences with SpectraShield or AP/M PermaForm?
Thanks Again.

Layup.
RE: Concrete Manhole Liner H2S
If so, was it on new or old manholes?
How long ago?
How have the liners/coatings held up?
Was there an H2S problem?
Anyone with experience please respond too!
Thanks.
RE: Concrete Manhole Liner H2S
We have also had good experience with the Raven lining applied on top of the calcium aluminate-based lining.
We have had good experience with FRP liners as well.
These werw all rehab projects due to proeblems with H2S. Most of these projects were done 5-10 years ago and were successful projects.
