Foundation Waterproofing

Exterior Drainage IowaExterior drainage in Iowa is sometimes overlooked, but with the annual threat of torrential rain and melting snow, your home should be prepared. Too often foundation contractors and home builders will only use damp-proofing methods instead of waterproofing methods like ECP perimeter drain systems.
Foundation waterproofing involves redirecting water away from the foundation. Exterior waterproofing can involve elaborate drainage systems or require less effort with proper gutter and downspout systems and landscaping.

Proper Exterior Drainage and Waterproofing

The number one thing needed to properly waterproofing the exterior of a structure is – care. Yes, you must care. You must use proper materials, take your time and have pride in the workmanship. Without these things your home will not be waterproofed correctly.

Moisture is transferred from the outside of the building to the basement interior by four primary mechanisms. First, water flow. Water takes the path of least resistance, if this is into your basement, then that is where the water will flow. Second, capillary action. Concrete is a porous material, it is very hard yet porous. Think of capillary action being like a wick. As concrete sets in water, this water is absorbed by the concrete until it becomes completely saturated and then disperses moisture and water vapor to the inside of the home.

Next is vapor diffusion. Vapor diffusion is much like capillary suction, except with water vapor. Water vapor only needs the smallest of openings to penetrate a structure and raise humidity levels. Lastly, air movement. Any time that a door or window is opened not only are you bringing air into the home but you are pulling air from the basement to the upper living levels. This is known as stack effect. Your home acts like a chimney drawing air from the bottom toward the top. On average about 50% of the air we breathe in our homes comes from the basement.

Should I Install an Exterior Foundation Waterproofing system?

Since you are protecting your biggest investment, proper basement waterproofing in Iowa should be done correctly and provide a permanent solution to your home. Remember though, exterior wall waterproofing cannot prevent water from moving deeply below your foundation walls. This water can move through your basement or crawlspace floor. In these cases an interior drainage system will complement your exterior efforts, not replace them.  An interior drainage system is not waterproofing. Interior drain systems are water management agents that relieve excess water from around and under your foundation.

Also, keep in mind that if you are moving the exterior water to a sump pump system, this system must be up to the task. Modern sump pumps, battery backup sump pumps and high quality sump basins are available to remove this collected water away from your home.
