Construction Instructions

To ensure a successful installation of SikaBit® PRO P-30-0 Sand, it’s essential to follow precise construction instructions. These detailed steps will guide you through the process, from substrate preparation to the final application.

Substrate Quality

• Structural Strength: Ensure that the supporting structure is of sufficient structural strength to accommodate the new waterproofing layers. For roofing applications, the entire roof system should be designed to withstand wind uplift loadings.
• Substrate Condition: The substrate must be uniform, firm, smooth, and free of any sharp protrusions, burrs, or irregularities that could impact the adhesion of the membrane.
• Cleanliness: The substrate should be thoroughly clean, free of grease, bitumen, oil, dust, and any loosely adhering particles that could hinder proper adhesion.
• Dryness: Make sure the substrate is dry. Do not apply the membrane to wet or damp surfaces.

Substrate Preparation

• Use appropriate preparation equipment to achieve the required substrate quality. This may include removing any debris, loose material, or contaminants.
• Address any irregularities or imperfections in the substrate by smoothing and leveling as necessary. Ensure the surface is ready to receive the waterproofing membrane.

Application Method and Tools

• Installation Procedures: Strictly follow the installation procedures as defined in the method statements, application manuals, and working instructions. It’s essential to adapt these procedures to the specific site conditions.
• Priming: Apply the appropriate primer from the SikaBit® P or Sika® Igolflex® P range to the prepared dry surface. The primer should be applied at the correct consumption rate as specified in the product data sheets. Allow the primer to dry fully before proceeding with the next stage of application. Always refer to the individual Product Data Sheets for precise primer details.
• Alignment: Unroll the membrane, align it correctly, and then re-roll it. Proper alignment ensures a smooth and even application.
• Overlap Dimensions: Maintain overlap dimensions as follows:
  • Side Overlap: 80 mm.
  • End Overlap: 150 mm.
• Torching Method: Use a gas burner to heat both the substrate and the backing film on the underside of the membrane. As the backing film starts to melt, the membrane is ready to adhere.
• Bonding: Roll the membrane forward and press it firmly against the substrate to create a strong bond. Ensure that a bead of melted bitumen is visible along the full length of the overlap sides and ends when laying the membrane. This visual indicator confirms proper bonding.
• Detailing: Pay close attention to detailing for internal and external corners, upstands, vent pipes, drains, support metalwork, or any other areas that require specific treatment. Detailing must adhere to recommended guidelines and best practices for torch-applied membranes.
• Protection: Throughout the construction process, protect the membrane from damage due to other site activities. Avoid excessive traffic or sharp objects coming into contact with the freshly applied membrane.

Maintenance

• To maintain the functionality of the waterproofing membrane during its lifespan, it is advisable to arrange for periodic inspections and maintenance.
• Inspection: Periodically inspect the membrane and detailing for any signs of damage, wear, or degradation. Check the functionality of auxiliary works, such as flashings, drainage outlets, and overflow pipes. Remove any debris, leaves, moss, or other vegetation that may have accumulated on the surface.

Important Considerations

• At low temperatures, take extra care when unrolling the membrane to avoid damaging it.
• Use suitable footwear to avoid puncturing the membrane.
• Do not apply the membrane to wet, damp, or unclean surfaces. Proper surface preparation is crucial for adhesion.
• Avoid over-torching the membrane as excessive heat can damage the polyester reinforcement (which melts at 260 °C), rendering the membrane un-usable.
• If the membrane is insufficiently heated during torching, it can lead to reduced adhesion to the substrate, between layers, or on the overlaps. In such cases, un-bonded areas must be lifted and re-torched.
• If a seasonal symbol is printed on the roll’s label, it is advisable to use the membrane during the indicated season for optimal performance.

By following these construction instructions meticulously, you can ensure the successful installation and long-term effectiveness of the SikaBit® PRO P-30-0 Sand waterproofing membrane in your construction projects. Proper installation is essential to achieve the desired waterproofing results and extend the lifespan of your structure.
