Commercial Waterproofing Solutions
Water intrusion can cause serious problems for commercial buildings. When moisture enters basements, foundations, or below-grade walls, it can damage concrete, weaken structural materials, and create costly repairs over time. Businesses also face operational disruptions when water problems are not addressed quickly.
STL Polyjack provides commercial waterproofing in St. Louis, MO to help protect buildings from water damage. Our team works with property managers, facility operators, and business owners to identify the source of water intrusion and implement effective waterproofing solutions that protect the structure and extend the life of the building.
Why Commercial Buildings Experience Water Intrusion
Commercial structures are constantly exposed to moisture from rain, groundwater, and drainage issues. Over time, water can find its way through cracks, joints, and weak points in the foundation or walls.
Common causes include:
- Cracks in concrete walls or foundations
- Poor exterior drainage around the building
- Water pressure against basement walls
- Construction joints that allow water infiltration
- Aging waterproofing systems or materials
When water penetrates the structure, it can lead to concrete deterioration, mold growth, and long-term structural damage if left untreated.
Signs Your Commercial Property Needs Waterproofing
Water intrusion problems are often visible before they become severe. Property managers and building owners may notice several warning signs that waterproofing repairs are needed.
You may need commercial waterproofing if you notice:
- Water leaking into basement areas
- Damp walls or floors in lower levels
- Visible cracks in concrete foundations
- Standing water around the building foundation
- Musty odors or signs of moisture buildup
- Concrete deterioration near walls or joints
Addressing these issues early helps prevent larger structural problems and costly repairs later.
In some cases, water intrusion problems are connected to other structural issues beneath the building. Saint Louis Polyjack also provides foundation repair and injection grouting to help seal leaks and stabilize the structure. If empty spaces form beneath concrete slabs, void filling may also be needed to restore proper support.

Our Fix: Commercial Waterproofing Solutions
Saint Louis Polyjack uses proven waterproofing methods to help stop water intrusion and protect commercial structures. Our team evaluates the building, identifies the source of moisture, and recommends the right repair strategy based on the structure and conditions.
Our approach typically includes three steps:
1. Identify the Source of Water Intrusion
We inspect the building to locate cracks, joints, and areas where water is entering the structure.
2. Seal Cracks and Penetration Points
Specialized materials and injection methods are used to seal cracks and prevent water from entering the structure.
3. Stabilize and Protect the Structure
Once the leak is addressed, additional repairs may be completed to strengthen the structure and prevent future water intrusion.
