Choosing the Right Masonry Waterproofing Products for Chicago Buildings

Chicago buildings face some of the harshest conditions for masonry in the country. Between freeze-thaw cycles, wind-driven rain, snow, and road salt, brick, block, and stone walls must be properly protected to prevent water intrusion and long-term damage.

At Roma Waterproofing Chicago, we specialize in professional masonry waterproofing for brick, block, and stone buildings throughout the Chicago area. One of the most important decisions we make on every project is choosing the right waterproofing system for the masonry being treated.

Not all masonry sealers are created equal, and the wrong product can lead to premature failure or moisture problems within the wall.

Chicago Masonry Requires Specialized Waterproofing

Chicago buildings commonly include several different masonry materials, such as:

• CMU / concrete block

• Split-face block

• Porous stone

• Harvard brick and other absorbent brick

• Chicago common brick

• Dense face brick

  
  

Many of these materials—especially CMU block, stone, and highly absorbent brick—are very porous. These types of masonry require penetrating breathable water repellents designed specifically for porous surfaces.

When properly applied, these systems penetrate deep into the masonry while still allowing the wall to release trapped moisture vapor. This is critical in climates like Chicago where freeze-thaw cycles can cause serious damage if water becomes trapped inside the wall.

Not All Waterproofing Products Are Designed for Porous Masonry

Some masonry sealers on the market are solvent-based products that advertise long warranties and deep penetration. These products can perform well on very dense brick surfaces, but they are not always the ideal choice for highly porous masonry such as:

• Concrete block (CMU)

• Split-face block

• Porous stone

• Highly absorbent brick

In addition, many solvent-based sealers are flammable and contain higher levels of solvents, making them less environmentally friendly than modern masonry protection systems.

Because of this, professional masonry contractors often select products designed specifically for the porosity of the masonry being treated rather than relying on a one-product-fits-all approach.

Why Roma Waterproofing Uses PROSOCO and Sika Products

At Roma Waterproofing Chicago, we use professional-grade masonry waterproofing products from PROSOCO and Sika, two manufacturers widely trusted in the masonry restoration and waterproofing industry.

These systems are designed to provide:

✔ Deep penetrating protection for masonry

✔ Excellent vapor permeability so walls can breathe

✔ Long-lasting water repellency

✔ Reduced environmental impact compared to many solvent-heavy sealers

✔ Professional-grade durability used on commercial and historic masonry projects

Products from PROSOCO and Sika are specifically engineered for masonry surfaces such as CMU block, porous brick, and stone, helping protect buildings while maintaining the natural appearance and breathability of the masonry.

Our Approach to Masonry Waterproofing

At Roma Waterproofing, our philosophy is simple:

Use the right waterproofing system for the specific masonry material.

For porous masonry such as block, stone, and absorbent brick, we apply penetrating water repellents designed to protect the masonry while still allowing moisture vapor to escape.

This helps:

• Reduce water absorption

• Prevent moisture intrusion

• Protect against freeze-thaw damage

• Extend the life of masonry walls

By selecting professional masonry protection systems from trusted manufacturers like PROSOCO and Sika, we help ensure reliable long-term results.

Signs Your Masonry May Need Waterproofing

If you notice any of the following issues, your masonry may need professional waterproofing:

• Water leaking through brick or block walls

• Damp interior basement walls

• Efflorescence or white staining on masonry

• Cracked mortar joints

• Dark or saturated brick after rainfall

• Interior moisture along exterior masonry walls

• 
  

These are often signs that water is entering the masonry and the wall system needs proper protection.
