Although your interior drainage system remains out of sight, it is an essential part of your basement waterproofing system. These drains protect your basement against water and humidity. A poorly installed or broken drainage system can wreak havoc in the long term. Ensure that it’s functional and clog-free, and you’ll never worry about waking up to knee-high water in the basement.

Signs of a Faulty Basement Drainage System

Recognizing the signs of a faulty interior drainage system is the first step in resolving the underlying problems. Here are some of the common signs:

Water in Your Basement 

Water spots on your basement floor, wall joists, or concrete slab are all signs of a defective interior drainage system.

High Humidity Levels  

If you notice your home’s humidity is unusually high, it’s a sign that your basement is wet due to a clogged or faulty interior drainage system.

Musty Odors

Surplus water and humidity usually cause mold and fungi to grow, and both create unpleasant smells.


If you notice white crystals at the bottom of your basement walls, it’s another sign moisture has been building up in the basement. You should get in touch with a qualified contractor in Indianapolis, IN, as soon as you notice this kind of formation to have the issue rectified.

Foundation Cracks 

Excess humidity levels in your basement can easily create cracks in your foundation. Since water is unable to make its way away from your home, it creates pressure on your foundation walls. If this water accumulation freezes, it is likely to crack your concrete walls.

Recurring Clogged Drains

If your drain keeps clogging up again and again even after routine maintenance, this could be a sign of bigger issues. Clogs that are accompanied by gurgling sounds or foul odors could mean there’s root infiltration. Ask your basement contractor to inspect your drainage system.

Slow Drainage Issues 

Interior drains usually get clogged with tiny soil, clay, and debris, which gradually accumulate inside the pipe. This can cause slow-draining pipes.

How to Clean Out the Interior Drainpipe

Water infiltration in your basement can be detrimental in a variety of ways. Other than damaging your belongings, a damp basement can lead to mold and mildew growth and unpleasant odors. It’s crucial that you address any interior drain problems in the shortest time possible.

While using a snake or plumber’s auger is a fairly straightforward DIY solution, we do not recommend it on certain interior drainage systems. Especially if you’ve had the BasementGutter™ interior drainage system installed by a contractor like Indiana Foundation Service, DIY clean-outs could result in damage to the pipe that also could affect your warranty.

The best thing to do if you notice an issue with your interior drainage system – whether it’s a BasementGutter™ system or not – is to contact your trusted basement waterproofing professionals. Expert technicians can inspect the pipes and clear out any blockages.

While your interior drainage doesn’t need much maintenance to function, it’s good to check it from time to time. Silt, dirt, and debris can build up in the drainpipe and obstruct water flow. To avoid this scenario, invest in a yearly basement maintenance plan that also takes care of the drains. Your contractor will unclog and clean out the BasementGutter™ so it can direct water away from your home.

If you still think there is excessive moisture and humidity in your basement or if you notice signs of water infiltration, your interior drainage may not be the culprit. You need to investigate the situation because moisture causes structural problems.
