Masonry Sealing & Waterproofing

What is Masonry Sealing and Waterproofing?

Masonry sealing and waterproofing refers to the process of applying a protective coating to the exterior of masonry structures such as brick, stone, and concrete. The coating helps to prevent water and other elements from penetrating the structure, which can cause damage over time. This damage may include cracking, spalling, and other types of deterioration that can weaken the structure and make it less visually appealing. By sealing and waterproofing the exterior, you can protect your structure from these types of damage and prolong its lifespan.

Why is Sealing and Waterproofing Your Masonry Structure Important?

Chicago is known for its harsh weather conditions, which can take a toll on the exterior of masonry structures. The city experiences heavy rainfall and snowfall, as well as extreme temperature changes throughout the year. These weather conditions can cause water to seep into the masonry structure, leading to issues like mold, mildew, and structural damage. Leading to issues like; cracking, spalling, structural damage, or mold and mildew. By sealing and waterproofing your masonry structure, you can protect it from these elements and prolong its lifespan. 

The Process

Masonry sealing and waterproofing is an important process for preserving and protecting brick, stone, and concrete structures in Chicago. This process involves three main steps: preparation, repair, and application. The goal of masonry sealing and waterproofing is to prevent water damage and extend the life of the structure. This is especially important in Chicago, which is known for its harsh weather conditions and varying temperatures, which can take a toll on masonry structures over time. Whether you have a brick building, stone walls, or any other type of masonry structure, a proper sealing and waterproofing job can help ensure its longevity and stability.

Step 1: Preparation

Preparation is a critical step in the masonry sealing and waterproofing process. The goal of this step is to ensure that the surface of the structure is completely clean and free of any contaminants that could affect the effectiveness of the sealant or waterproofing material. To accomplish this, the surface may need to be pressure washed or cleaned with a chemical cleaner. This step is important because even the smallest amount of dirt or grime can create a barrier between the surface and the sealing material, preventing it from properly adhering to the surface.

Step 2: Repair

The second step in the process is to make any necessary repairs to the structure. This may include filling in cracks or gaps, replacing damaged bricks or stones, or addressing any other issues that could impact the effectiveness of the sealing material. This step is important because even small cracks or gaps can allow water to penetrate the structure, causing damage over time. Additionally, any damaged or missing masonry will need to be repaired or replaced so that the sealing material can be applied to a solid, continuous surface.

Step 3: Application

The final step is to apply the sealing material. This step can vary depending on the type of structure and the materials used. For example, a liquid sealant may be painted or sprayed onto the surface, while a membrane or coating may be applied. Regardless of the specific application method, it is important to have a qualified masonry contractor assess your structure and recommend the best course of action. The contractor will be able to determine the right type of sealing material, the appropriate application method, and the necessary steps to ensure that the sealing material is applied properly and will effectively protect your structure.
