How should reinforcement be installed in a Built-Up Roof (BUR) membrane?

In the installation of a Built-Up Roof (BUR) membrane, reinforcement should be embedded in layers of waterproofing material. This practice is essential because it allows the reinforcement to provide structural integrity and enhanced durability to the roofing system. When reinforcement is embedded properly, it helps to distribute stress evenly across the membrane, reducing the likelihood of cracking or other forms of damage that can occur due to environmental factors such as temperature changes, humidity, and physical stress.

Additionally, embedding the reinforcement in layers of waterproofing material ensures that it is fully bonded to the roofing system, which helps to prevent moisture intrusion and improves the overall effectiveness of the roof. This method creates a more robust and long-lasting roof assembly as opposed to placing the reinforcement above or along the edges, where it could be more susceptible to exposure and damage.

The option to not use any additional layers could compromise the effectiveness and lifespan of the roof, making it less resilient to common challenges faced by roofing materials. Thus, embedding the reinforcement within the waterproofing material is the best practice for achieving a durable and effective BUR membrane.
