Exterior Foundation Waterproofing In Chicago

When performing exterior basement waterproofing we excavate around the foundation to expose the poured concrete or masonry walls. After cleaning and repairing any cracks or damage, we apply a high-quality waterproof membrane, such as a liquid membrane or a durable sheet membrane, to seal the foundation. We also install a dimple board or similar drainage system to manage water buildup and reduce the risk of damage from wet soil or rising groundwater. The entire system is designed to prevent water from entering your basement, even during heavy rain or snowmelt.

By waterproofing foundation walls and the exterior of the basement foundation, you’ll enjoy healthier living conditions, maintain your home’s structural integrity, save on energy costs, and protect against future foundation issues.

Regular maintenance is key to ensuring that your waterproofing material remains effective over time. We recommend periodic inspections to check for any signs of wear, cracks in the concrete wall, or damage to the drainage system. It’s important to ensure that all components, including the drainage mat and any installed sump pumps, are functioning properly. Routine maintenance will help extend the life of your waterproofing system and keep your foundation protected against moisture.

While DIY methods for applying basic exterior waterproofing products exist, it’s highly recommended to hire professionals for proper installation of a complete waterproofing system, especially in areas like Chicago with extreme weather conditions. Our team uses specialized tools and we ensure that all components, such as drainage systems and membranes, are correctly installed to handle heavy rain, snowmelt, and rising groundwater.

In addition to exterior foundation waterproofing, we provide basement leak repair, moisture barriers for basement walls, and resealing basement walls. Our services also include installing basement window wells, egress windows, and window well coverings. 

We use premium exterior waterproofing materials including durable liquid membranes, self-adhesive or torch-applied sheet membranes, and high-quality drainage systems like a dimple board. These materials are designed to withstand extreme temperature fluctuations and manage both surface water and groundwater effectively. Additionally, they help prevent issues caused by rising humidity levels in crawl spaces or basements.

When water accumulates in the ground around your home due to poor drainage or heavy rainfall, it creates what’s known as hydrostatic pressure. This pressure pushes against your foundation walls, especially if they’re made from porous materials like concrete or masonry. Without proper waterproofing measures like a robust membrane or drainage system, this pressure can cause cracks in your foundation walls or even lead to water infiltration into your basement or crawl space.

Drainage is critical in any exterior basement waterproofing project because it helps manage both surface water (like rain) and groundwater (like rising water tables). We install systems such as French drains or perforated pipes along with a protective layer such as a dimple board or drainage mat. These systems work together to direct water away from your home’s foundation, reducing the risk of damage caused by excess moisture or rising groundwater.

Temperature fluctuations can impact certain types of exterior waterproofing materials, especially those that rely on adhesives or liquid applications. For example, some liquid membranes may have specific temperature limitations during installation to ensure proper curing. In colder climates like Chicago’s winters, it’s essential to use materials that are designed for low-temperature application.
