r/drains

Sorry if this isn't the right place for this question, send me to the right sub if needed!

We're having a concrete patio poured and I didn't really think about or notice how it would affect the way the yard drains. Both companies we had come out didn't mention anything either. My concern is the corner of the patio will creat a barrier for water to pool and sit. White flags mark where the planned patio will land. Tried to draw where the water flows but the pics may not show well.

We're scheduled for next Tuesday so wanted to see what solutions are out there.

Can a low profile drain be laid in the direction of flow and concrete poured over it? Do we need to trench and put in a catch basin out to the back of the yard? Do we just make the patio a bit smaller and avoid the extra work?

Thanks for any input and ask me more if necessary!

This home near me has a French drain with no daylight. Heavy clay soil. Any idea why he wouldn’t just daylight into street? Central Nj, not sure if there is an ordinance. I see plenty of people daylight gutter drains into street.

I have similar style yard, considering the same but would prefer daylight.

We bought this house about 8 years ago and knew this was here but always just thought it was for storm drainage to drain rainwater out to the street. Later we found out from neighbors that our home was the model home in this late 1960’s development and that it was built on a spring. We hiked up the property behind ours and thought we found the spring so never really considered this could be what they were referring to. This is approximately 15-20 feet from the house.
We were recently hacking away our neighbors English Ivy and uncovered this again. We would like to do something in this area. Could this be the spring the neighbors were referring to? Is this how developers control a natural spring? How does this work? Where does that bottom pipe go? Is water going into that or coming out? Is water coming out of that and overflowing into the surrounding concrete pipe? Or is groundwater in the concrete pipe draining into the small pvc pipe?
Could I put a pump in it and make this a water feature? It’d be awesome to build a tiny pond/waterfall around this.

Hi all,

Back in 2023, we bought a house with a very nice garden that features a retaining wall. Over the last few years, the plaster and paint has started showing cracks due to humidity, and the corner beads are becoming rusty in multiple places.

This year, we want to add a flower/plant border and fix the issue of the wall at the same time. We've currently dug down to the height of the upper part of the wall and cleared space up to the electric outlet in the bed. There was a plastic sheet above the outlet against the wall, but we didn't encounter any other measures against humidity.

I suspect we need to add a drainage system, but I'm not entirely sure how exactly and how to evacuate the water.

Does anyone have advice or experience with handling drainage for a wall like this?

Thanks a lot!
