Protecting your home from the unique challenges of Iowa's climate requires robust solutions.

Our proven methods, including meticulous excavation and advanced membrane systems, provide a long-lasting barrier against water intrusion, ensuring a dry and healthy basement for years to come.

Understanding Iowa's Water Challenges and the Need for Exterior Waterproofing

Iowa's geology, particularly around the Des Moines metro area, is characterized by significant deposits of clay soil. This clay is highly absorbent and expands when wet, exerting immense pressure—known as hydrostatic pressure—against your basement walls. When combined with heavy rainfall, spring thaws, and fluctuating temperatures that cause repeated freezing and thawing, this pressure can lead to cracks, leaks, and significant structural damage to your foundation. While interior basement waterproofing solutions address water once it has entered, exterior waterproofing proactively stops water at its source, preventing it from ever reaching your foundation walls.

Our Comprehensive Exterior Waterproofing Process

Our approach to exterior basement waterproofing is thorough and tailored to the specific needs of your Des Moines home. The process typically involves:

1. Careful Excavation: We begin by carefully excavating the soil around your home's foundation, exposing the exterior basement walls down to the footing. This step is performed with precision to minimize disruption to your landscaping.
2. Wall Preparation and Repair: Once exposed, the foundation walls are thoroughly cleaned. Any existing cracks or vulnerabilities are meticulously repaired using high-quality, durable materials to ensure a smooth and stable surface for the waterproofing application.
3. Waterproof Membrane Application: A robust, seamless waterproof membrane is then applied to the entire exterior surface of your basement walls. This specialized barrier acts as the primary defense, preventing moisture from penetrating the concrete or block.
4. Drainage Board Installation: Over the waterproof membrane, we install a drainage board. This material creates an air gap and provides a clear path for water to flow downwards to the drainage system, preventing it from pooling against the membrane.
5. Perimeter Drain Tile System: A new, high-capacity perimeter drain tile system (also known as a French drain) is installed at the base of the foundation, collecting water channeled by the drainage board and directing it away from your home, often to a sump pump system.
6. Backfilling and Restoration: Finally, the excavated area is carefully backfilled with appropriate soil, and your landscaping is restored as close to its original condition as possible.
