Tenera was tasked with providing repair specifications of an exterior expansion joint at a hospital facility in Newmarket. Expansion joints, which accommodate the natural movement of structures due to temperature fluctuations, play a vital role in maintaining the integrity of the building. Over time, the material w sithin these joints can degrade due to exposure to the elements, necessitating periodic repairs.
Repair Method
The repair process began with a thorough cleaning of the joint to remove the worn-out material. This step is crucial, as any residual debris or deteriorated material would compromise the effectiveness of the new sealant. Once cleaned, the expansion joint was injected with a polyurea-based material. Polyurea is highly flexible, allowing the joint to contract and expand as the structure responds to temperature changes. Additionally, polyurea is known for its resistance to ultraviolet (UV) rays and other environmental factors, ensuring the joint remains protected against long-term exposure.
Benefits of Polyurea-Based Liquid Membranes
Polyurea-based liquid membranes offer several advantages in the context of expansion joint repairs. Their ability to stretch and recover allows the material to accommodate structural movements without cracking or losing its integrity. This flexibility is especially important for exterior applications where the joint is exposed to varying temperatures and weather conditions. Furthermore, polyurea membranes are highly resistant to UV radiation, preventing degradation from sunlight exposure. Their quick-curing properties also reduce downtime, which is particularly important in settings like hospital facilities, where minimizing disruption is essential.
Importance of Expansion Joint Injection
Injecting and maintaining expansion joints is critical to preserving the structural health of any building. Over time, the constant movement of the structure can lead to joint failure, allowing water infiltration and other environmental factors to penetrate the building envelope. This can result in costly repairs and potential damage to the structural components. By injecting expansion joints with durable, flexible materials like polyurea, building owners can prevent water ingress, improve the joint's longevity, and ensure the overall stability of the structure.
At the hospital in Newmarket, this repair ensures that the facility remains protected against environmental stresses, enhancing both safety and durability for years to come.
