Basement Waterproofing Systems

Avoid foundation repair and increase the value of your home by installing a basement waterproofing system, such as an exterior/interior waterproofing system.

 

 

There are few home projects that could be more important and potentially costly for your home than installing a basement waterproofing system. Basement remodeling projects are expensive for a reason: water damage can lead to some very steep repair costs and can significantly lower the value of your home and potentially causing health issues for your family.

 

Although homeowners from all areas of the country need to be concerned with proper foundation drainage, it is especially important in the Springtime, when heavy rainfall puts more stress on basement walls.   Cracks, dampness and mold on and in basement walls is primarily due to a phenomenon called hydrostatic pressure, which increases as the surrounding ground becomes saturated with rainwater. Saturated soil is much heavier than dry soil, which causes undesigned pressures on basement walls.

A good basement waterproofing system will allow excess water to be channeled away from your home's foundation, thus reducing the amount of hydrostatic pressure on your walls.  This is done using perforated footing drains, which run around the perimeter of the home and deposit excess water in a sump pit or daylighted away from the foundation.Many types of basement waterproofing systems can be installed in or around your home, and they are generally differentiated by internal and external functions.  Internal basement waterproofing systems can fix visible problems such as moist walls or mold, but they are much less effective at eliminating hydrostatic pressure than external waterproofing systems. 

While exterior systems can be more invasive, they are the one true form of waterproofing.When considering a basement waterproofing system, make sure that you get an estimate on a complete solutions, opposed to a Bandaid.  While internal basement waterproofing can be effective for many basement water problems, you should also consider proper maintenance for your footing drains and external drainage system as well.  While it may cost more to excavate and replace footing drains, it adds significant equity to the value of your home, and may stave off a potentially expensive flood or foundation repairs.

 



Interior Basement Drainage Systems

Hire a waterproofing contractor to install a basement waterproofing system. A sump pit and open back system will eliminate excess water from your basement.

 

 

 

When it comes to draining water from around and under basements there is a single preferred method and a whole host of less desirable methods. This preferred method is named many things but has a few basic elements that engineers and professional waterproofing contractors prefer.

1.       Sealed System

2.       Pitched Drain Piping

3.       Cold Joint Drainage

4.       Below Slab Drainage

First of all, any plumbing system must be sealed from the living area to prevent increasing humidity levels which can lead to mold growth, higher radon levels and bacteria growth. This can be seen in many older homes which have a damp and musty cellar smell due to poor drainage and open cavities in floors and walls.

Secondly, any plumbing system must be based on the simple principal that water, among other things, flows downhill. Without positive slope, pitch, water will sit in place opposed to flowing downhill to a collection point where it can be directed away from the foundation.

Next, water enters a basement from a path of least resistance. Often times this path is the cold joint between the footing and wall. Water can migrate through this joint due to pressure caused by the downward force that saturated soils place on the footing.

Lastly, interior drainage systems must remove water from beneath the basement floor. As many homeowners know, basement floors become cracked due to water that is trapped below the concrete floor. This trapped water is constantly looking for a path of escape and can crack a concrete floor very easily.

So with this information in hand it becomes very simple to determine the best interior basement drainage system. The system must be closed, or sealed from the living space. This will include a sealed sump pit and sealed piping system that is laid around the perimeter of the basement walls. Many systems have open backs designed to capture water that is running down the walls. These open back systems will capture wall water but remember if things can get in they can also get out. These open backed systems allow water vapor and radon an easy path to your living space. Closed or sealed systems prevent this phenomenon from happening by their very nature of being sealed from living spaces.

Open backed systems have another primary fault and that is the fact that they are laid on top of the footing. Concrete footings are poured flat so that the basement walls can be poured or laid upon a flat surface. Any drainage system that is laid on top of the footing cannot be pitched to drain the water that they collect. The water sits in these systems promoting mold and bacteria growth which can cause clogging and health concerns. Also, if you place drainage pipe, along with a bed of clean gravel, next to the footing you will gather the water before it comes in contact with the basement floor. By doing this you can prevent floor heaving and cracking. Open backed systems that sit on top of footings must have the water rise above the bottom of the concrete floor before they can accept any water. Closed systems allow water to enter much earlier and since they are next to the footing they can be pitched toward a sump pit for collection and discharge.

Before you contract any waterproofing company to solve your basement moisture problem keep the above items in mind and demand that the proper techniques are used. Now that you know what must be included with your new basement drainage system, ask questions and do not be fooled by their slick answers.

 



Sump Pump Freezing

Waterproofing experts can prevent sump pump freezing by installing a freeze guard. Water can escape from your discharge line if the pipes are frozen.

 

 

With the winter weather that most of the country is now experiencing many homeowners are finding out the hard way that sump pump discharge lines can freeze, especially in the northern regions. With snow and ice building up outside of homes, sump pumps cannot run effectively unless they are designed correctly. When sump pump systems freeze, your basement and everything in it can be in jeopardy.

Sump pump discharge lines can become covered with snow and ice in the winter, causing frozen pipes and backed up sump pump systems.  Frozen sump pump discharge lines can spell disaster for your basement and the belongings that you store.

Professional waterproofing experts prevent sump pump freezing with the ECP Sump Pump Freeze Guard. The freeze guard system allows water to escape from your sump pump discharge line if the underground discharge pipe freezes or becomes blocked for any reason. No matter if the pipe outlet is buried under a foot of ice and snow, the water can escape, allowing your sump pump to keep your basement safe from flooding. When the discharge pipe thaws, the water will automatically run through the buried discharge line. The system is simple and very effective in protecting your basement from frozen sump pump systems.
