Exterior Foundation Waterproofing

Water problems in basement are a health problem as well as a nuisance. Periodic flooding renders the basement unusable. Water cannot be controlled, just managed. Our approach is to waterproof the basement foundation from the positive side with a protective drainage board.

Exterior foundation waterproofing is the preferred method of waterproofing a basement foundation, preventing water from entering the basement from the exterior. The effected area of walls are excavated from the exterior, cleaned and prepared for waterproofing material. For small projects, Bakor WP200 waterproofing membrane is applied to the primed foundation wall. Over top of the membrane is a water drainage and protection board is applied, Bakor WP 2000 These Bakor basement waterproofing products are the very best on the market and come with a manufacturer's warranty.

Weeping tiles are either a clay tile or plastic pipe that extends around the base of the foundation footing to collect any water that accumulates. The weeping tile is connected to either a sewer or a sump pit, today all new homes have sump pits and pumps. After installing the waterproofing and protection board, the weeping tile are inspected and checked to ensure they are functioning. If the weeping tiles are not functioning, a high water pressure contractor is called in to flush out the weeping tile around the home.

If the weeping tile can not be flushed out, or if there is no weeping tile, the only option is to install a sump pit and pump. A section of weeping tile is installed along the section of foundation wall being repaired, and connected to the new sump pit on the interior of the basement.

Interior Foundation Waterproofing

The closed interior waterproofing system is a state of the art method for controlling water from the interior with no excavation. Without a proper seal, moisture will leech back into your basement providing no solution to your problem. The completely sealed system protects against groundwater minimizing moisture and the entry of harmful gases into the basement. The system draws water from both outside walls and the basement center, where the water is then directed into the drainage trench. In addition, the complete seal reduces the presence of bugs and rodents. Should it be necessary the system is completely accessible to ensure years of efficiency.

While exterior waterproofing of the foundation is the preferred method, sometimes it is just not possible for a number of reasons: extensive landscaping, or pavement, decks, trees, as well as limited access to excavate or for economical reasons.
Our Number 1 Interior Basement Water Control System. - This system is the only closed system offered. By closed we mean that the water never enters into the home. A sealed flame retarding membrane is applied from the top of the interior foundation wall down and over the footings. A specialized drainage tile is installed below the basement floor to collect any water that runs down the basement foundation wall. This drainage tile is attached to the sump pit and pumped out with the sump pump.
The benefit of this system is no water or moisture is emitted to the basement environment.
Installation takes about two days.

Dual Chamber Sump pit and pump

Non-Clogging Sump Pit & Pump with Backup Sump Pump

The most revolutionary sump pit and pump manufactured in North America. The 1/3 horsepower pump is the most energy efficient, controlled with not one but two switches for more reliability. After every use, the backwash directly cleans the propellers to prevent it from clogging. The sump chamber has a built in pedestal to raise the pump above the bottom where all the sediments lay that could otherwise clog the sump pump. The chamber is only 16" deep to prevent undermining the basement foundation allowing it to be installed close to the basement foundation wall. The level and secure lid makes it safer without impeding on basement floor space.

Perhaps the most important factor is the diagnostic center with built-in alarms to inform you in advance if there is a issue with the sump pump system. You no longer have to experience a flooded basement to know you sump pump didn't work! For homes in rural areas with frequent power outages or in areas with high water tables, we recommend a secondary chamber and battery back up sump pump system with a computerized controller to give you that additional protection and peace of mind.

Humidity/moisture Control

It is essential to keep the humidity in your basement below 45% relative humidity. When this might be possible in the winter with the furnace running, it is not so easy in the summer. Unless you have a means to control humidity, you may be wasting your time fighting with mold and mildew in your home. We have the most advance dehumidifier on the market today!
