Waterproofing

What is Foundation Waterproofing? 

Every new foundation needs to be waterproofed. Spray application of seamless waterproofing on the exterior of a foundation turns the interior into a dry basement. Now the basement living area stays dry and free of water. Without foundation waterproofing, water can seep through a foundation wall or through a crack.

According to the testing and approval criteria of the ICC-ES for foundation waterproofing, it must do three things: 

  • Span a crack in a foundation

  • Withstand water under hydrostatic pressure

  • Stop water vapor from entering a basement

For decades using traditional foundation waterproofing only damp-proofed, which only stops water vapor. Water under hydrostatic pressure can still push its way though a damp-proofed foundation. Also, damp-proofing is brittle and cannot bridge cracks in a foundation. Many people call this "waterproofing", but it is not.

The Difference Between Dampproofing and Waterproofing

 On the left: Dampproofing is unable to bridge over cracks that develop in the foundation, letting water into the basement.

 

 On the right: All Around foundation waterproofing membranes have rubber polymers that allow the waterproofing to span cracks in a foundation, thus preventing water from ever entering a basement.

A New Way to Waterproof Foundations  

To stop water from entering a foundation, waterproofing needs to be seamless, stretch over cracks and withstand water under hydrostatic pressure caused by heavy rains. Spray applied polymer-modified asphalt exterior foundation waterproofing stops water on the outside, before it can get into a basement wall. 

Hydra-Guard Waterproofing Membrane, and the Hydra-Guard Waterproofing System are ICC-ES evaluated foundation waterproofing materials that meet these criteria. 

Benefits of Foundation Waterproofing

Foundation waterproofing is a seamless barrier that protects your belongings in the basement from water damage. This enables a homeowner to increase their living space. In fact, basement living space is the least expensive living space to build in a home. Now you can turn your previously unused basement into anything you want; a rec room, workshop, or entertainment area.

Foundation waterproofing reduces the moisture in a basement. Waterproofing prevents water vapor cannot move through the basement walls. This lowers the amount of moisture in the basement and helps eliminate musty odors and other allergens that bother people. Dry air in the basement

also makes the room more comfortable to be in. The room won’t feel sticky in the summer or chilly in the winter.

Stopping water penetration into the basement will

  • Protect your possessions from water damage

  • Increase your home’s living space

  • Keep the basement walls clean and dry

  • Eliminate musty odors

Why Use a Polymer-Modified Foundation Waterproofing Membrane

There are several different forms of foundation waterproofing on the market. The most common is polymer-modified asphalt. This is a liquid asphalt coating that has rubber polymers added. The rubber polymers enhance the asphalt to allow it to stretch over shrinkage cracks. Now water cannot penetrate into the basement even if the foundation cracks. Polymer-modified asphalt waterproofing membranes dry to form a seamless, smooth and continuous barrier to water.

Polymer-modified asphalt waterproofing has several advantages going for it. In addition to being highly effective, the cost of installation is very low compared to other waterproofing products. This is because since they are liquid, they can be sprayed onto a foundation wall at a high rate of coverage. One man hour of application will result in many more square feet of a foundation being treated compared to other types of waterproofing.

The cost of materials is also usually lower for liquid foundation waterproofing membranes. In fact the cost per square foot of installation can be 1/3 to ½ the cost of other waterproofing products

More Steps to Keep Your Basement Dry

Making a basement dry doesn’t just start with foundation waterproofing. There are other systems and features that need to be included as a building is being built to be sure the basement stays dry.

 1. Foundation Drainage System

All waterproofing products need to have a functioning ground water drainage system in place. This is simply a perforated pipe that goes around the bottom of a foundation and either drains water to daylight, or if that is not possible, then collects the water in a sump pit. From there a sump pump removes the water from the foundation area. 

The purpose of a foundation drainage system is to remove ground water that accumulates around a foundation and under the basement floor. Foundations that lack or have an improperly working foundation drainage system can have water actually enter the basement at the joint where the floor meets the foundation wall.

 2. Soil Grading

In addition, the grade of the soil around the building should slope away from it. Grade that slopes towards the building can cause a pooling effect that can get above the area treated with waterproofing. When this happens, the water can enter any cracks in the foundation and enter the basement.

Damp proofing

All Around Foundation Waterproofing is now offering custom tint damp proofing above the grade line. Though we suggest waterproofing below the grade, custom damp proofing can be used for the exposed foundation to match the custom color of the home, for a continuous color to the ground.

What is Damp Proofing:

Damp proofing has one main purpose; stop the transference/wicking of ground moisture through the foundation. This is accomplished by creating a capillary break, preventing moisture from passing through the capillaries inherent in the concrete.

Damp proofing can be effective on poured concrete and concrete block foundations and it is allowed by the residential building code if certain soil conditions exist.

Damp proofing is not effective on foundation cracks or on wood foundations.
