Hi all, I am currently in a year long gut renovation project that has me at my wits end. From day 1 I let our contractor know that we’d like to cement our entire backyard and he basically brushed it off and kept saying we have plenty of time for that. Well, the time has come and now that I requested he start cementing, he tells me we can’t cement the back yard because of the drywells. I have no idea what he’s talking about but I am aware that 3 large drywells were installed underground in our backyard. Two large ones for the house and one smaller one for the garage. Now, correct me if I’m wrong but shouldn’t they have connected additional pipes running from the drywall to specific areas in the backyard leading to drains? Please give me a rundown of how this is supposed to work if my goal is to cement the backyard and driveway. I’m losing sleep over this because there’s a never-ending issue with everything I’ve requested and I’m getting fed up. Thank you so much!
 
what are the the purpose of the dry wells? it it is to catch and hold run off rain water then a pipe should go to them from what ever drains they serve. this piping should go underground and then into the dry well. an access door will be required to inspect from time to time .

If the dry wells are required for water runoff abatement then cementing the back yard would force you to add drainage capacity for the cemented surface so as not to increase the rain runoff from impervious surfaces. Grass is part of the solution to rain runoff while paved areas are part of the problem.
