Where Is The Basements Leak Coming From?

The key to any serious problem is to eliminate it at its source. In the case of a wet basement, the source of the problem is the point where water enters your home.

However, finding this problem is often easier said than done. Water can leak into a basement from various points, each with their own cause and solution. In some cases, as with finished basements, you may need a professional to determine exactly what kind of water problem you have.

Locate The Leak In Your Basement

Basement leaks can come from nearly any point in the walls or floors, including through cracks, around pipes, and through entryway points from the outdoors.

Below is a list of the seven most common sources of basement leaks, as well as the solutions we offer to solve them:

Severe basement leaking through the wall-floor joint in a home

Flooding Through The Wall-Floor Joint

The most common way that water leaks into a basement is through the basement wall-floor joint. This is the point where the basement walls meet the floor, which is poured separately from the walls for most basements.

This joint is usually the weakest point when hydrostatic pressure leads to water pressure against the basement walls, and severe flooding can occur in the basement through this point.

To stop this kind of water intrusion, a drainage system should be installed along either the interior or exterior perimeter of the foundation. This drain will collect the water and either direct it to a sump pump system, or it will direct it downhill away from the foundation.

At Basement Systems, we prefer to install interior drainage systems. Exterior systems require the entire outside perimeter of your home to be dug out, which is expensive, time-consuming, and damaging to your landscaping. Exterior systems also tend to clog with mud and debris, and when they do, the only way to access those drains is to dig out around the foundation again.

Interior drain systems are about half the price of exterior methods, and they install in about a day. The system is easily accessible for service, and it installs with no need to disrupt your landscaping. These systems have been used in tens of thousands of basements by Basement Systems contractors over the past 20 years, and we find them to be a lasting, highly effective way to waterproof a basement.

Wet Basement Floors

When a hole was excavated to make room for your basement, the soils that were excavated were hard-packed, settled soils that had been there for, perhaps, hundreds or thousands of years.

After the home is built, some of that soil is poured back, to fill in the gap underneath the floor and around the foundation walls. This soil will always be lighter and more "fluffed" than the hard-packed soil around it.

Because of this, water will absorb more readily in these soils around your foundation than in the untouched soils beyond. This creates a "clay bowl effect", in which the water pools around your home. This water will try to enter your basement through whatever way it can.

If floors have cracks, this gives it the opening it needs to enter your home and flood your basement. A perimeter drainage system will still be able to collect this water, intercepting it before it floods underneath your home. However, if your floor has a large crack that is leaking excessively, we may also run a drain from that crack (known as a "lateral line") to your perimeter system.

A leaking pipe penetration point in a basement wall.

Leaky Walls, Cracks & Pipe Penetrations

Water can make its way through the walls in four ways:

  1. Through cracks in concrete walls
  2. In around improperly sealed pipe penetrations
  3. Through gaps in grout in stone walls
  4. Seeping through concrete walls themselves

Provided that there is no foundation problem, The first two of these can be solved with our FlexiSpan® wall repair system.

The FlexiSpan® includes a special polyurethane polymer, which is injected into the crack. This injection should stop 95% of the leakage. Then, a foam strip directs any excess water down into a special dry well created during installation.

Next, the dry well is covered over with concrete, and a covering is placed on top of the covering for a professional, tooled-off look.

The best way to handle #3 and #4 on the list is to cover the walls with a waterproof covering that tucks into the waterproofing system. These walls can be tucked into your drainage system at the bottom, directing water on your walls to your sump pump. The result? A long-lasting solution to your problem that keeps your basement looking great!

A basement flooding from the hatchway stairs opening, located.

Water From Hatchway Entrances

Many homeowners complain that water is entering through to their home through the basement door from the outside. Alternately, water may enter through the door of a walk-in basement, or through a garage door entrance.

In cases such as these, we can extend a perimeter drainage system across the doorway, using a specialized drain that includes a grated opening on top.

The grated opening will intercept the water before it enters your basement, directing it to your sump pump. The water is kept out of your home, protecting everything inside.

A basement that's flooding through the windows.

Basement Window Flooding

Basement windows often flood as the windows themselves corrode and water pools outside.

If your basement window wells are clogged and filling with snow, ice, or water, this will make the situation much worse.

One good way to repair a leaking window is to replace the window with a new, energy efficient window, along with a covered window well.

With new basement windows and window wells, you'll be protected from leaks, while the window improves your energy efficiency, and the window well cover stops the cold winter air.

If you're not interested in replacing your basement windows and window wells, you can instead install a drain from the window to your drainage system. This will capture water, directing it to your sump pump.

A failed water heater flooding basement.

Failing Water Heaters

A water heater can be expected to fail approximately every seven years. When they do, it will often result in water leaking directly on to the basement floor.

We can address a potential flood from a failing water heater by installing a plastic ring around the unit. If you have a perimeter drain, the ring will drain into your waterproofing system, and ultimately to your sump pump.

If you have no perimeter basement waterproofing system, we'll place a small water sensor inside the ring. If your water heater floods, it will sound off, notifying you of the leak.

Two washer hoses, one brand new, and the other old and corroded.

Bursting Washer Hoses

Washing machine pipes are meant to be turned on when the washer is in use -- and off when it is no longer being used. If you have old-fashioned rubber washing machine hoses and do not do this, you're at risk of a big flood.

Washer hoses are not designed to take the continuous 60-80psi of pressure that is exerted against them at all times. If they burst, as much as 650 gallons of water can burst out!

There are cases where Basement Systems dealers have seen water rise up to the windows, due to broken washing machine hoses. To help prevent this disaster, we provide a long-lasting, durable washer hoses that include a 20-year warranty.
