I am looking to control water coming in one corner of a walk out basement, concrete block walls. Surface water has been taken care of - gutters, downspouts, slope, outside french drain. It seems that when it's wet out for long periods water works its way up from below the house. Only comes in one corner of the basement. No sump pump in basement now.
My choices are; just put a sump pump in that corner and hope that solves it and add drain tile later if it doesn't. ($1350)
Do sump and 30ft of drain tile now ($2500)
Any thoughts? Your wise opinions will be greatly appreciated.
If the water entering the basement is only at that one corner then a sump in that corner will solve the problem.
Everyone recommends drain tile all around the foundation because you never know when a long rainy spell could result in water seeping up in other places in the basement.
If the French drain* outside is below foundation level then it can be tied into the sump (pit) and no additional drain tile is needed. You would need to run a pipe under the foundation footing to connect the French drain with the sump.
* French drains can be either on the surface or underground. Those on the surface do not need to enclose the collected water such as in a perforated pipe.
Don't let the weatherman string you along. Stick to your lawn watering schedule until it actually starts pouring.
