Question DetailsAsked on 7/20/2016

Jefferson, I am wondering if you can give me any advice/instructions on how to complete waterproofing our basement?

Jefferson, we have had to completely gut and redo our basement twice since purchasing our home. We have only lived here 6 years, so it is getting to be frustrating in the least. I saw your post on how you did it on your own and am very interested on how you did yours. I have Jesse Trebil (sp?) coming out this Friday to do an evaluation and quote us on putting this system in, but have heard from others it is quite spend. I then saw your post on how you were able to waterproof your basement for under $100 and was very interested in how this was done. I would really appreciate any advice you have for us. Thank you!

Jefferson has not posted anything here for probably pushing a year or so, so you might not get a response back from him - don't know if he still prowls this site or not (he was a contributor, not an AL employee).


You can find lots of previous questions with answers about wet basement issues in the Home > Basement Waterproofing and Home > Mold categories in Browse Projects, at lower left.


Found the particular post you mentioned here (he actually referred to it twice) -

In case he does not answer back, in his case it sounds like it was just a matter of putting on a downspout extension and one buried 4" drain pipe (possibly extending a french drain) to get roof runoff coming down the downspout(s) far enough away from the house so it did not wet the basement wall. For $100-150 a downspout extension, a bit of DIY excavation or fill berming to prevent runoff from geting to the foundation from the yard, or a spot leak through the foundation wall that could be plugged with grout or sealant are about all you could fix for that amount. Otherwise, I don't see it being fixed for anywhere near $100.


In most cases, for general multi-point water entry you are talking hundreds to thousands of $ depending on what is needed - in almost all cases except high groundwater levels keeping the water away from the foundation with swales, berms, drains in the yard etc is far better than trying to block it or drain it AT the foundation. However, in cases where high groundwater is the problem, exterior foundation base-level french drains, full foundation wall waterproofing on the outside (commonly both are done together) or installing drainage under the slab leading to a sump pump is the only solution as a retrofit. The best solution is almost always to keep the water at bay and as far from the foudnation as possible - first trying to stop it in the yard or lot entry point, second to keep away from the foundation wall at least 6-10 feet if possible, third to provide french drain and water barrier at the foundation wall outear surface, last resort is interior subfloor drainage.


My emphatic recommendation - please don't fall for above-slab interior drainage systems around the perimeter of the basement slab, and DEFINITELY do not go for any system that punches holes in the foundation wall to drain exterior water into a sump pump indoors - there is little worse than intentionally increasing the flow through/under your foundation into a sump pump system, especially when your pump or power fails and you find tens of gallons per MINUTE pouring in rather than the normal few gallons to few tens of gallons per HOUR that most sump pumps have to handle.


Lots of discussion about the alternatives and common sources of inflow in the previous Basement Waterproofing questions and answers.
