First, the simplest and least costly techniques are to remove excessive internal moisture sources in the basement (humidifiers, cooking) and ventilate other sources (clothes dryer, bathroom). Second, if condensation in the summer is the problem, do not ventilate the basement directly with warm, humid air. Remove moisture from the air with a dehumidifier. A dehumidifier isn't a permanent solution to moisture in the basement, but it will remove excess humidity while you fix the cause of the problem. Place the dehumidifier in the dampest part of the basement and turn it on. Left unchecked, basement moisture can ruin floors and walls, encourage mold, even damage roofing. Here are eight strategies to keep water out of your basement. Add Gutter Extensions. Plug Gaps. Restore the Crown. Reshape the Landscape. Repair Footing Drains. Install a Curtain Drain. Pump the Water. Waterproof the Walls. The most effective way to keep water out of your basement is to install an interior drainage system that minimizes hydrostatic pressure. By installing drain tile along the joint where the floor meets the wall, where most water leakage occurs, you can capture water before it makes its way onto the basement floor. Ground Water The most probable explanation for why water is coming up from your basement floor is groundwater. This can include cracks in your floor, cracks in the wall, and yes even through the floor. Your basement floor is made of concrete, and concrete is porous allowing water to soak through it.

A damp basement is commonly caused by moisture migrating through a concrete foundation. There may not be a sign of any leak or standing water, but the moisture evaporates, increasing indoor humidity. Another common cause is condensation on the cold concrete walls and floors during humid months.

How to Get Rid of Humidity in the Basement Without Dehumidifier? Airflow to reduce humidity: Crystal Salt as Desiccant to Absorb the Moisture: Charcoal as Desiccant to Absorb the Moisture: Silica gel as Desiccant to Control Humidity. Install Fan and Proper ventilation. Line Dry Clothes Outdoors ( In Sun ) :

Moisture problems in existing basements are very common, but often are not understood or properly treated. In a basement that is seldom used and separate from the living spaces above, this may not present a great problem.

Here's a quick list of a few things to look for: Water Trickling Out of the Walls. Saturated Base of Concrete Walls (a ring of dampness) Condensation on the Walls and Floor. Stained or Blistering Walls. Damp, Humid Air. Standing Water on the Floor. Deteriorating Carpet or Wood. Rotting Columns, Headers, and Joists.

A few good methods for getting rid of basement bugs incude: Set up sticky traps. Learn about the bugs in your basement so you can feel more at home with them. Encapsulate your crawlspace. Install a dehumidifier. Use a bug fogger. Get rid of clutter. Use a peppermint oil spray.

Common causes are leaks in the ceiling or a crack in the exterior of the home which both permit water to enter. If the water is seeping up through the floor, it could be a result of insufficiently-sealed foundations or there could be cracks in the foundation floor.

Rainwater, melting snow or groundwater can saturate the soil around your foundation and leak in. Water can leak through cracks, or it can penetrate porous concrete or masonry walls in the form of water vapor. Moisture behind the foil means moisture is leaking through the walls.

Seal the Floor Use a sealer designed for concrete moisture protection, such as an epoxy concrete sealer, which often comes in two parts that must be mixed immediately before applying. Pay special attention to the corners and edges of the floor, where cracks can let extra moisture seep in.

Basement Waterproofing Cost. The average homeowner spends around $4, 285 to seal a basement or foundation, with minor repairs costing as little as $600. More comprehensive issues that include fixing cracks in the foundation or adding drains & gutters can cost upwards of $10, 000.

You should always seal concrete with a moisture barrier primer sealer or paint. Use low VOC or non VOC if possible. Any store should carry low voc concrete sealer. Use a clear coat to ensure lower voc's than stains.

Flex Seal can be used on almost every surface: wood, metal, tile, concrete, masonry, fabric, glass, plastic, aluminum, porcelain, drywall, rubber, cement, and vinyl. Plus, it won't sag or drip in the summer heat, and it won't crack or peel in the winter cold. It even prevents corrosion.

The most effective way to keep rainwater out of your basement is to install an interior drainage system. A proven solution for keeping the basement dry, a good waterproofing system minimizes hydrostatic pressure. An interior drain tile connects to a sump pump.

DO apply a masonry waterproofing product to bare interior basement walls. If your foil test showed that water is soaking through your basement walls and leaving them wet, seal the interior of the walls with a high-quality waterproof paint, such as DRYLOK White Extreme Waterproofer (available from Home Depot).

Call in a professional plumber or water damage specialist to pump the water out as soon as possible. Whenever flooding occurs, regardless of the water level, if you can access your main electrical service panel without entering the basement, turn off power to the basement.
