Why do you find water in basement during new construction?

A new house is always a milestone in everyone’s life. But dealing with an entire house means you’ll be facing all sorts of issues. Like finding black soot on your toilet seat.

On top of that, you’ll have to furnish your house too. So, all together it’s a lot of responsibility.

And the water in your basement will not make things easier for you. While we cannot help you with everything today we’ll start by helping you guide through the battle against the water in your basement.

Shall we start?

Reason 1: Water leakage inside the wall

The most common reason for finding water in your basement is water leakage. You see, the water pipes can get damaged from time to time.

And when that happens the water comes creeping into your basement. Moreover, this leakage can drown your entire basement so you need to act quickly to fix it. If left unchecked, this leaking will cause efflorescence in the basement.

Solution – Fix the leak in the wall

In order to fix the leakage, you simply have to repair the water pipe. Now for this, you can either replace the water pipe or treat it with epoxy putty.

Either way, you should call a plumber to take care of the job for you. It’s best to let the professional handle this.

Reason 2: Grading problems

Ineffective grading can cause several major issues like water hammer in the line, leakage, and in the worse cases, water sitting inside your basement.

The ground that surrounds the foundation can sometimes end up pointing towards your house. And if your entire draining system points towards your house it’ll be a huge problem.

That’s because when the rainwater starts piling up they will eventually enter your house. So, you gotta fix it before it turns into a hassle.

Solution – Aim the slope away from your home

Now to solve the grading system you can gather up dirt around the slope. This will make the foundation face away from the house.

And the next time rainwater wants to go somewhere it’ll be far away from your house. However, make sure that the dirt reaches one inch per foot otherwise it won’t work against the pent-up water.

Reason 3: Fault of gutters and downspouts

Another item responsible for water in your basement is gutters and downspouts. And no they are not any Christmas lights that you can plug into sockets.

Their job is to make sure water heads away from the foundation of your house. Now, if it’s missing, water can start gathering up in the soil of the house.

Then slowly make their way to the basement. Moreover, if you have gutters and downspouts then check on them. It can get dirty from time to time.

Solution – Clean the gutters

As for the solution to this problem, it’s very easy. All you have to do is get gutters and downspouts if you don’t have them.

And if you do then clean the gutters up with a garden trowel to ensure that water doesn’t enter your territory again.

Reason 4: A dent in the foundation

While people assume that letting the water run on a sink in island can cause the basement to overflow with that, that’s rarely the case. You see before the water reaches your basement you’ll notice it. And stop the occurrence at once.

On the other hand, a more common reason for seeing water during new construction is a dent in the foundation.

Now the interesting fact is that water itself can cause this.

You see, foundations cannot hold a high-pressure water supply. So, they get crackled and water slips in through that to reach your basement.

Solution – Repair the crack

Now, to fix the crack you need to seal it up with hydraulic cement. Make sure you wait a few minutes for the cement to dry off.

And once it does dry up. You’re all done. Additionally, you can use a dehumidifier to keep your basement dry. But if you can’t get one, you can still keep your basement dry without a dehumidifier.


Question: Can water come up through the concrete basement floor?

Answer: Yes, water can crawl through the concrete basement floor and make everything soggy and wet. So, don’t rule out the possibility of a faulty water pump only because it is covered by concrete.

Question: Does homeowner insurance cover water in the basement?

Answer: Well, typically your homeowner insurance will cover the damage created by the water in the basement. However, you need to read the agreement thoroughly. That’s because the agreement does not directly state “insurance money for water damaged”. It is usually termed a bit differently. So, keep an eye out, mate.

Question: How long does it take for a completely flooded basement to dry out?

Answer: Since the basement does not have any access to the sun it takes a long time to dry up completely. With that being said, it can take from 12 hours to an entire week for the water to completely disappear.

Question: Who do you call when you have water in your basement?

Answer: A plumber will be your superhero when your basement is flooded with water. You see, the majority of the time you find water in your basement due to a leak in the water pipes. So, the right man to deal with this is a plumber.

To sum up

Well, that was all the causes and solutions for dealing with water in basement during new construction. We certainly hope this guide helped you pinpoint your problem.

And you did find the main culprit then you know how you can handle it.
