Common Causes of Basement Moisture

Overview of How Water Can Infiltrate Basements

Understanding the sources of basement moisture is the first step in effectively waterproofing your basement. Common causes include:



• Hydrostatic Pressure: Water in the soil surrounding the home’s foundation can exert pressure (hydrostatic pressure) on basement walls, leading to cracks and water seepage.
• Condensation: Warm, moist air can condense on cooler basement surfaces, leading to dampness and promoting mold growth.
• Poor Drainage: Inadequate drainage around the home can cause water to pool near the foundation, eventually finding its way into the basement.
• Cracks and Gaps: Over time, the natural settling of a house can lead to cracks in the foundation and gaps around windows or doors, providing entry points for water.

In the comprehensive strategy of basement waterproofing, sump pumps play a pivotal role, acting as a dynamic defense mechanism against water intrusion. This essential tool not only mitigates the immediate challenges posed by water accumulation but also contributes to the long-term preservation of the basement's structural integrity. This section explores the basic mechanics of how sump pumps operate to remove unwanted water and discusses their critical function in preventing water buildup, thereby safeguarding the basement against potential damage.

How Sump Pumps Work

Basic Mechanics of Sump Pumps and How They Remove Water

At its core, a sump pump is ingeniously designed to efficiently manage and expel water that has accumulated in the basement, typically in a specially constructed sump pit. Here's how it functions:

• Water Collection: The sump pit, positioned at the lowest part of the basement, collects excess water, whether it seeps in through the foundation, walls, or floor. This can be due to rain, groundwater, or melting snow finding its way inside.
• Activation: As water fills the sump pit, it raises a float switch or activates a pressure sensor, which in turn triggers the sump pump to start.
• Water Evacuation: Once activated, the sump pump uses its motor to power an impeller that pushes the water out of the pit and through a discharge pipe. This pipe directs the water away from the home's foundation, typically to a storm drain or a dry well, effectively removing the threat of water damage.
