Why parapet wall maintenance is important…
A parapet is a low wall constructed above the roofline that usually spans around the perimeter of a building. Parapets may be purely aesthetic or functional, as they can hide mechanical equipment or act as a fire barrier.
The top of a parapet wall is vulnerable to moisture penetration problems. Choosing an appropriate cap is an effective way to eliminate potential water damage. CTC Masonry’s services for parapet wall repair in Chicago include tuckpointing, rebuilding, waterproofing, and more. We provide a variety of materials to cap off the wall. These materials include:
- Limestone
- Terra cotta/clay
- Precast concrete
These materials have different physical properties – choosing one over the other largely depends on the application and the aesthetic appeal you are looking for. We’re well versed in brick and concrete block repair, making us your best choice for parapet repair no matter what you have.
CTC Masonry takes on all types of parapet wall repair in Chicago using a variety of techniques. When the back side of the wall is completely exposed, both outer wythes should be constructed of the same material with brick on the backside. This brick should be protected by a roofing membrane or a chemical water repellent. Our parapet wall waterproofing methods are both proven and effective.
