The Service

Sealing brickwork is an important part of masonry waterproofing, as it prevents water from penetrating the walls and floors of buildings. Brickwork is typically sealed with a silane-based water repellent to form a protective barrier against water. This water repellent must be reapplied at appropriate intervals  in order to maintain its effectiveness. Our team of skilled professionals specializes in sealing masonry to ensure your buildings stand strong against the elements. By implementing best-in-class techniques and materials, we strive to deliver high-grade sealing solutions that help in extending the lifespan of your brickwork.


Understanding the dynamics of sealing brickwork and masonry waterproofing is essential to the integrity of your building. The silane-based water repellent we use is carefully applied, forming a protective barrier against water. This water repellent is breathable, meaning any water that does get behind the brick is not trapped, and is allowed to pass through the brick or stone. This not only prevents immediate water damage but also combats the long-term effects of moisture, including mold growth and structural compromise. Remember that staying on top of sealing masonry is important. Regular reapplication of the water repellent  at the appropriate intervals is key in maintaining this protective shield, and our team is committed to assisting you in this crucial maintenance.
