Frequently Asked Questions
What if I do not waterproof expansion joint?
Waterproofing expansion joints is crucial to prevent water infiltration, which can cause structural damage and deterioration. It ensures the building’s durability and reduces maintenance costs by keeping the joints sealed against moisture.
Can we waterproof an expansion joint that was not previously waterproofed?
How long can waterproofing of expansion joint lasts?
Waterproofing of expansion joints is very long lasting, depending on the materials used, environmental conditions, and maintenance practices. If application done properly, it lasts long.
How waterproofing of expansion joints can be done?
To waterproof an expansion joint, first joints will be filled with PU (Polyurethane) sealant to create a flexible, watertight barrier. After the sealant cures, lay Tapik Joint Seal Tape over the joint and secure it with a moisture resistant adhesive. This combination ensures a durable and flexible waterproofing solution.
why waterproofing of expansion joint is comparatively costly than other areas?
Waterproofing expansion joints is comparatively costlier because it requires specialized materials and techniques to accommodate joint movement and ensure a durable, watertight seal. The process often involves more labor and precision compared to other areas.
What happens if I delay waterproofing the expansion joint and wait until water leaks?
Waterproofing expansion joints is not easy and becomes even more challenging if done after the top layer of the RCC slab is in place. It requires breaking and cleaning the joints and edges, which is labor-intensive and costly. The current cost of proper waterproofing is much lower than future expenses for labor, debris disposal, and repairs. In some areas, it may become impossible to waterproof effectively later, making partial work ineffective. Therefore, addressing waterproofing needs promptly is more practical and economical, especially in the case of expansion joints.
