Waterproofing Catch Basins
Waterproofing Catch Basins
(OP)
Hi All,
I am working on a 140 unit condo project that has offsite street improvements. We are proposing sump and on-grade catch basins which get built prior to onsite. The outlet SD pipes from CB's drain south through the site that get built with onsite improvements. My question is, as the offsite street and catch basins get built first, how do I prevent the storm water from getting into the catch basins, specially the sump CB? Is there a way to temporarily waterproof the CB (not just providing the filter fabric and sand bags?
Thanks.

My bigger curiosity is what happens to the surface water at the sumps if the basins are not functioning?

Water is going to pond up and spill over the curb onto onsite which would be rough graded at that point of time with a silt fence at the ROW behind the Catch Basin. I think it would also pond the half street that we are improving.
May be I am overthinking, It does not really rain in California anymore :)
