Whether you are dealing with seepage in a basement, moisture in exterior walls, or recurring leaks in foundation areas, Winco is here to help you keep your home dry and protected.

Waterproofing vs Dampproofing in Residential Construction

Many homeowners are not sure which type of protection their home needs. While both systems relate to moisture control, they serve different purposes.

Dampproofing:
This is used on exterior cavity wall systems to keep moisture from entering and to allow any condensation to drain out of the wall system quickly. It helps maintain a dry and healthy wall assembly. This is common between stone, CMU, sheathing, and plywood on many residential structures. Winco understands when each system is required and uses high-quality products chosen specifically for your home’s construction style.

New Residential Waterproofing for Home Construction

Proper waterproofing during new home construction is essential. Unfortunately, it is also one of the most common areas where builders overlook important details. Missing membranes, improper application, and incorrect product selection can all lead to leaks that appear years later.

Winco delivers accurate takeoffs and installs systems the correct way from the start. We work closely with builders throughout San Antonio to ensure that critical waterproofing details are never missed. Our team covers all structural points where moisture can enter and uses premium products that meet residential building standards.

Remedial Residential Waterproofing and Repairs

Moisture problems in an existing home can be caused by foundation settling, clogged drainage systems, missing sealants, or aging materials. Winco has more than 30 years of experience identifying the true source of leaks and correcting them with durable, cost-effective solutions.

We avoid temporary fixes and instead focus on repairs that extend the life of your home’s protective systems. Sometimes a small additional step, such as surface pretreatment or a bond breaker that prevents three-sided adhesion, can improve the lifespan of a system by many years. These details are part of the Winco difference.

If you are looking for waterproofing solutions for a business, facility, or larger structure, Winco also provides a full suite of commercial waterproofing services. Our team handles everything from below-grade systems to large-scale sealant and membrane installations for commercial buildings across South Texas.
