Before installing the membrane, proper surface preparation is essential to ensure adhesion and optimal performance.

Applying a primer serves as a crucial intermediary step to enhance the bond between the substrate and the torch-on membrane, ensuring a secure and long-lasting waterproofing solution.

The application of the SHIELDO Sand membrane involves heating the material with a torch to create a seamless bond with the substrate.

Once the membrane is in place, finishing touches such as sealing the edges and seams are done to enhance water-tightness.

Conducting a ponding test on the torch-on sand membrane is crucial to evaluate its performance under standing water conditions. The test involves creating a controlled ponding situation on the membrane surface and monitoring any signs of water ingress or membrane failure. After 48 hours of continuous ponding, the following observations are typically assessed:

• Water Tightness: The membrane should demonstrate excellent water tightness, with no signs of water infiltration or leakage.
• Adhesion Strength: The bond between the membrane and the substrate should remain intact, ensuring long-term performance.
• Surface Integrity: The membrane surface should show no signs of damage, blistering, or delamination due to prolonged water exposure.
• Drainage Efficiency: Proper drainage of water from the ponded area is essential to prevent excessive stress on the membrane and substrate.
