Commercial Waterproofing in San Antonio

Professional Protection for Commercial Buildings and Facilities

Water intrusion can interrupt operations, damage interiors, weaken structural components, and create expensive liabilities for any commercial property. Winco of South Texas provides high-performance commercial waterproofing systems that safeguard your building and support long-term structural health. With more than three decades of experience, our team understands the unique demands of commercial construction in the San Antonio region and takes a detail-oriented approach to both prevention and repair.

Commercial buildings face greater exposure to the elements, heavier use, and stricter compliance requirements than residential structures. Even a small leak can escalate into mold, damaged insulation, structural deterioration, or disruptions to tenants and customers. Winco evaluates each property to eliminate moisture issues at their source and prevent new problems from developing.

New Construction Waterproofing

On any commercial build, proper waterproofing is only successful when planning, product selection, and installation are aligned. Winco works closely with general contractors, architects, and project managers to ensure every detail is executed correctly. Over the years, we have corrected countless issues created by incomplete drawings, overlooked installation steps, or mismatched materials. These mistakes can void warranties, cause long-term failures, and force costly repairs.

Our approach focuses on accuracy from the beginning. Each bid is clear, detailed, and built around real-world needs. We identify where systems should be placed, recommend the most reliable products for that specific application, and make sure installation supports the overall performance of the building envelope. Contractors appreciate that our takeoffs are dependable, our pricing is transparent, and our team knows how to anticipate potential issues before they impact the project.

Winco installs a full range of commercial waterproofing and dampproofing systems using specialty membranes, sealants, flashing, insulation, and repellents. These materials are selected based on durability and compatibility with the structure, ensuring your building is protected through every season and operating condition.

Remedial Waterproofing for Commercial Properties

Water intrusion in a commercial building requires a precise diagnosis and a long-lasting solution. Winco has spent more than 30 years repairing, restoring, and upgrading waterproofing systems across retail centers, government buildings, hospitals, industrial complexes, office buildings, warehouses, and other commercial sites. We understand how moisture travels through structures and how a failure in one area can create damage elsewhere.

Our goal is to correct problems with methods that improve performance rather than simply masking symptoms. Sometimes a small change, such as treating a surface correctly or applying a product with the right primer, can extend the life of a system by several years. We approach each building as if it were our own, taking the time to evaluate the conditions, verify the source of the issue, and recommend the best solution based on your budget and long-term goals.

Remedial services may involve updating old membranes, replacing failed sealants, repairing flashing, applying protective coatings, or installing negative-side waterproofing when exterior access is limited. Every solution is tailored to the building’s age, material type, and exposure.
