Parapet Wall Repair

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 parapet wall repair services 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.

CTC Masonry takes on all types of parapet wall repair projects in the Chicagoland area using a variety of techniques. When the back side of the wall is completely exposed, both outer wythe’s 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 waterproofing methods are both proven and effective.

Reasons for parapet wall deterioration…

  • Improper flashing installation 
  • Improper coping material
  • Failure of masonry due to weathering
  • Water damage

With the harsh seasons Chicago experiences, it is important to properly maintain these walls, as they are an important component of the masonry and roofing system.
