Product Overview
APP Modified Bitumen Waterproofing Membrane
APP modified bitumen waterproofing membrane combines petroleum asphalt, APP (Atactic Polypropylene) polymer modification, reinforcement, and selected surface finishes into a torch-applied membrane system for roofing and waterproofing applications.
APP-modified membranes are commonly selected for projects where heat resistance (up to 130degC), dimensional stability, and durability under elevated roof temperatures are important selection criteria. This makes APP the preferred choice for hot-climate regions, high-solar-load roofing, and exposed mineral-finished roof systems.
TY-SHIELD supports project-specific APP membrane supply by reinforcement type, thickness, upper-surface finish, quantity, export packing method, and OEM private-label requirements. Contact our team with your project specification for a competitive factory quotation.
Available Configurations
Select the reinforcement, thickness and surface finish to match your project requirements. Contact us with your specification for a tailored quotation.
| Configuration | Reinforcement | Thickness | Surface | Recommended Use |

All thicknesses and surface finishes shown are available in standard production. Custom roll dimensions, packaging and private-label printing are available subject to minimum order quantity. Final configuration should be selected according to climate, substrate, waterproofing system design, exposure condition and local project specifications.
Applications
Basement & Foundation
Suitable for selected below-grade waterproofing assemblies where an APP modified torch-applied membrane is specified by the project system.
Underground Waterproofing
Suitable for selected underground structures, retaining walls, and project-specific waterproofing assemblies subject to approved system design.
Infrastructure Projects
Available for selected bridge, municipal, and water-conservancy projects subject to model-specific technical confirmation.
Key Benefits
Heat Resistance
APP polymer modification supports membrane stability in elevated temperature and high-solar-load roofing environments, maintaining integrity where standard membranes may soften.
Dimensional Stability
Reinforced membrane construction helps maintain the intended membrane geometry during installation and under normal thermal cycling in service.
Suitable for Exposed Roofing
APP membrane configurations with mineral granule surfaces are commonly specified for exposed hot-climate roof systems requiring UV resistance.
Project-Specific Configurations
Select the appropriate reinforcement, thickness, and surface-finish combination for non-exposed, multi-layer, or mineral-finished roof systems.

Installation Guide
Prepare the Substrate
Ensure the substrate is smooth, dry, clean, and free from loose material, sharp projections, standing water, oil, and debris.
Apply Compatible Primer
Apply compatible bitumen primer where required and allow the primer to dry before membrane installation.
Pre-Lay and Align
Unroll the membrane for positioning, align overlaps and details, then roll back the membrane section for torch application.
Heat and Bond
Heat the burn-off PE film and substrate evenly until the bitumen layer is ready for bonding, then roll forward with controlled pressure.
Packaging & OEM
Export Roll Packing
Rolls are vertically palletized and secured with heavy-duty strapping, stretch-film, and protective wrapping for safe ocean transit.
Branding Support
Custom wrapping films, private labels, and branded core sleeves available for wholesale partners.
OEM Labeling
Custom pallet labels, outer-package markings, and brand-specific core sleeves available.
Storage
Store horizontally in dry conditions between +5degC and +30degC in original packaging. Shelf life 12 months.
