❓ Frequently Asked Questions

Waterproofing stops rain and moisture from entering the building, while thermal insulation reduces heat transfer. In Saudi Arabia, especially in Riyadh and Jeddah, combining compatible waterproofing and thermal layers on roofs or car parks can protect the structure and improve performance.

Yes, liquid and membrane systems can often be applied over existing roofs or under tiles after joints and cracks are repaired. Durability depends on the roof condition and moisture source, so a technical inspection is recommended before work, especially in hot, humid areas like Jeddah.

Liquid systems are flexible and fast for flat roofs. Membrane systems are durable against sun and foot traffic, making them suitable for exposed roofs. Polyurethane seals joints and corners tightly. Choose based on roof type, budget, use, and application temperature.

Life ranges from about five to 25 years depending on the system, workmanship, and climate. In Saudi Arabia, exposed roofs should be visually checked in summer, joints cleaned, and any cracks or blisters repaired immediately to prevent water leaks.

Yes, Matkel offers contractor pricing based on project size and supply period. Written warranties are available for compatible waterproofing systems that meet Saudi construction requirements, provided the surface is prepared and the product is applied correctly according to instructions.
