Common Basement Leak Problems and Solutions

Basement Waterproofing Company | Best Cost | Walls & Floor | BWN
Basements are designed and built as masonry structures that extend below ground. When the disturbed soil that surrounds the basement saturates with rainwater, this water will find ways to enter through the basement walls into the home’s environment. Water seepage has consequences that reach far beyond the basement. Ignored, this moisture will quickly and easily find its way into the home’s living spaces.

Leaking Walls

When basement walls have staining, dampness or active water passing through, it is time to have the walls waterproofed. Water can pass through the basement wall or enter over the top of the basement wall. These wall problems can be permanently fixed.

When basement walls have staining, dampness or active water passing through, it is time to have the walls waterproofed. Water can pass through the basement wall or enter over the top of the basement wall. These wall problems can be permanently fixed.

Solutions

HIGH PERFORMANCE VAPOR BARRIERS
Permanent encapsulation of your basement walls can not only control water but serve to drastically reduce the moisture effecting the basement’s living space.

POLYURETHANE WALL CRACK INJECTION
Polyurethane is a waterproofing resin mechanically injected directly into the wall crack to permanently stop water from passing through a basement wall.

PIPE PENETRATION REPAIR
When your basement wall is penetrated by a water or sewer pipe, these wall openings need the correct sealant to create a permanent repair.

Water on Floor

When you see dampness or water on your basement floor a waterproofing system is needed to correct this type of problem. These problems can be permanently fixed.
Water on Floor

Solutions

INTERIOR BELOW FLOOR DRAINAGE SYSTEM
Properly designed and installed, this system will prevent water from ever reaching your basement floor and keep your living space safe from water. This system requires a sump pump to discharge the water up and out of the basement.

INTERIOR ABOVE FLOOR DRAINAGE SYSTEMS
For certain types of basement foundations, this system is designed to permanently control water without having to remove the basement floor. This system requires a sump pump to discharge the water up and out of the basement.

NEW CONCRETE FLOORS
When it is necessary to provide a new concrete basement floor, a complimentary waterproofing system is needed to ensure a seamless installation and long term result. This system requires a sump pump to discharge the water up and out of the basement.

Water on Floor

Basement Stairwells

Exterior basement stairwells can collect and guide water straight into your basement. Most problematic is once the water starts to enter though the basement door opening it will continue until the rain stops.

Solutions

EXTERIOR STAIRWELL DRAINS
Properly designed and installed stairwell drains collect surface water and remove it before it can cause flooding. It is imperative these drains are installed properly to avoid the risk of polluting your waterproofing drainage system.

INTERIOR CHANNEL GRATE DRAINS
Interior channel grate drains serve as an additional measure of protection for basement door leaks preventing water from collecting on the basement floor.

SOIL STABILIZATION
There are times when dirt and mud wash out from under the exterior basement stairs onto the base pad and create problems by blocking surface drains and clogging drainpipes. This problem often negatively effects the interior waterproofing drainage system. Soil stabilization is a process of polyurethane grout injection to stop movement of soil under the stairwell steps thereby protecting valuable stairwell drains and basement waterproofing systems.

STAIRWELL MAKEOVERS
To avoid basement stairwell replacement, the stairwell walls and base pad can be structurally restored with a cosmetic refresh. The process of correcting structural deficiencies is achieved through wall reinforcing and concrete resurfacing. Stairwell makeovers allow homeowners to safely regain the use of their stairwells while avoiding expensive replacement costs.

Basement Windows

Basement windows are collection areas for water and the cause of costly interior damage. A permanent repair requires several solutions working together.

Solutions

CUSTOM WINDOW WELL DRAINS
Window well drains quickly collect the water and direct the water to an evacuation point. This eliminates water building up in the wells and protects the windows from water seepage.

WINDOW WELL EXTENSIONS
Window well extensions are designed to keep soil, mulch and surface water away from the critical area of the window opening in the foundation. It is important that the window well extensions are installed at the proper height to ensure the window opening is protected from surface debris and water.

Downspouts

Downspouts collect water from gutters and often dump water at the worst possible place, right against your foundation. Some downspouts are extended with pipes on the ground that quickly become a nuisance and look terrible. We have a solution.

LANDSCAPE BASINS
A landscape basin is designed to disburse collected water from downspouts in a gentle manner without causing soil erosion. When these attractive, durable basins are installed properly, you can mow right over top of the landscape basin when cutting your grass.

BURIED DRAIN LINES
To help move water away from the critical areas around your foundation, buried lines are the appropriate solution. No more ugly pipes in your yard. The use of proper materials and installation techniques make this a permanent solution.

Basement Humidity

Humidity is water vapor in the air. When elevated levels of moist air get trapped in the basement, it is known as high humidity. This interior climate problem needs to be rectified to remove musty odors, stop further damage to building materials, and prevent a favorable environment for mold to reproduce.

Solutions

The special filters help clean the basement air by removing mold spores and other airborne contaminates, thereby restoring and safeguarding your basement’s environment.

Basement Leaks and Repairs

Basement waterproofing is a permanent solution that can protect your basement in its entirety from past, present, and future water problems. A properly designed and installed waterproofing system using the right materials and workmanship should last forever.

When it comes to water seepage, leaking, and flooding in a typical basement, waterproofing is almost always the ultimate solution. Basement waterproofing, when done properly and professionally, will provide you with a basement that stays dry under any and all conditions.

How do you go about waterproofing your basement?

First, contact a specialist for a proper diagnosis of your basement problem. Basements are complex foundation structures that require professional attention. A company that specializes in basement waterproofing will have the knowledge, experiences, and resources needed to understand your home’s particular construction and accurately determine the cause of any water leakage and water damage.

Second, be sure to fix it right the first time. Steer clear of sales pitches that recommend poorly designed, low cost solutions focused on short term improvements to get a quick sale and complicated solutions with bells and whistles designed to justify high prices. Every day we hear the stories from people who had other companies attempt to fix their issues only to have them recur with worsening consequences because the real problem was not solved. Avoid this costly mistake.

Finally, be sure your waterproofing contractor will fully guarantee their work in writing. This will ensure they are truly accountable to their recommendation and their results.

If you think you have water leakage or water damage in your basement, contact us now to properly specify and design the perfect waterproofing system for your home. We’ve earned a 5 star reputation for installing premier waterproofing solutions since 1987, backed by our 100% satisfaction guarantee.
