How to stop water seepage on my basement cinder block wall?

My basement is waterproofed from the inside and has a sump pump. However, on one wall in my basement, water is seeping through the cinder block and causing mold to form. This wall is located on the side of the house where the driveway is and the mold is located on the part of the wall that is directly below my side entry door. We have tried to stop water from entering by caulking around the house on the driveway side and underneath the entry door and have applied dry-lock masonry waterproof paint to the wall but the wall is still wet. I do not have water on the floor of the basement, just resting on the wall and causing mold to form. Is my interior waterproofing system faulty? Any ideas on how to fix the problem?

    You have a problem. You need to get a professional to look at that. Not only is it a problem, but if not taken care of quickly it will become very expensive. You already have a mold problem and that means the seals between the cinderblocks are filled with mold and I would start there for where the water is coming in. If it becomes toxic mold, yikes! The first thing you need to do is have the seepage problem fixed, then have the mold remediated. Sadly not going to be cheap and insurance companies will not cover it anymore.

    i'm a roofer so i know that water can run in funny ways when you have a leak. you make it sound like the driveway is right up against your foundation. if this is the case, is the driveway cracked or sagging? i'm not just talking about right next to the house. watch where the water runs or puddles during a rain storm. do you live in a cold climate and does the ground freeze? i'm in CT, where i live a previous owner added a cellar hatchway to the basement. they put this in right next to the back porch/pantry foundation, and made it out of cinder block. the one foot of ground between the foundations is sandy soil and soaks up water. during the cold weather that freezes and shifts the hatchway blocks causing water leaks. i "fixed" the problem by rerouting the downspout from the gutter on one side and creating a plastic sheet trough under gravel on the other side. it was a simple fix, and easy since i only had to dig sand. in your situation it sounds like you need to have the driveway cut and dug out and have a drain tube installed in a plastic lined, gravel filled channel. that would be the cheapest way out until you have to repave the driveway and can have it pitched away from the foundation. for now spray a bleach/water solution on the wet walls to keep the mold at bay and get a dehumidifier to take the moisture out of the basement. good luck and hope you get some good ideas to help you out.

    What is on the other side of that wall?

    Let's see, the driveway, any grass?

    Could a water facet be on the outside of the wall

    so a hose could be attached to wash the car, or

    water the plants?

    A friend told me to be sure to unhook the water hoses

    that hook up to the facets on the outside of my house

    each Fall. He said, if you leave the hose on, the water

    left inside could freeze and burst the water pipe

    inside the wall.

    Is there a water pipe for the hose outside, inside this wall?

    If so, it could be busted, or leaking.

    bypass on your community homestead center and yet Hydraulic cement. you will would desire to combine it up your self yet its quite uncomplicated.(basically upload water till it somewhat is the consistency of peanut butter) then fill interior the crack. there is likewise an epoxy which would be used with a caulking gun even inspite of the shown fact that it would not mixture in besides. the two technique works nicely.
