"Terrible just terrible don’t ever use this company, I hired Innovative to help level my concrete they did a horrible job. Now my driveway has more and even bigger cracks, also I was over charged by the representative who gave me the quote, I specifically asked him that I did not want any cracks filled that I would do it that myself but he ended up charging me for a portion without my knowledge, I found out after it was filled with caulk. I tried calling them about it a few times since I have a 5 year warranty but know one has bothered to pickup my call or respond back. They will easily over charge you to get an extra few 1000 from your pockets. DON’T EVER USE THIS COMPANY they don’t care about you nor bother to even know your name, not once did the representative bother to ask or know my name even though I took the time to know his I was known as “Hey” the entire interaction. Stay away from this company use any other."

Basement Waterproofing questions, answered by experts

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

Sandbags are the most common and efficient way to create a flood barrier at home. Some local authorities pass them around to homes before the risk of a flood. Otherwise, you can use flood-proof house materials, like burlap or woven plastic bags, to make sandbags and fill them with sand or cat litter. Make sure that when you stack them, they’re tightly laid on top of each other, creating the effect of a firm wall against accumulating water.

Alternatives to gutter systems include rain chains and drip edges, which work to disperse rain coming off of your roof to a wider section of the ground to prevent erosion and pooling. These options aren’t standalone alternatives to gutters in all parts of the country because they don’t divert water. They’re often reserved for dry climates. On the ground, you can also opt for a drip path or French drain. These can serve as standalone alternatives, but they’re expensive and can detract from your curb appeal and usable yard.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.
