Polyvinyl Chloride (PVC) Waterproofing Membranes

Applicate Standards:GB 12952-2011

Product Introduction

Polyvinyl chloride (PVC) waterproofing membranes are rollable waterproofing materials manufactured using advanced equipment and production processes, with polyvinyl chloride resin as the primary raw material, combined with anti-aging additives and other specialized additives.

Product Features

　　1、Long service life and excellent resistance to aging.

　　2、High tensile strength, high elongation, and minimal changes after heat treatment.

　　3、Good flexibility at low temperatures and strong adaptability to environmental temperature fluctuations.

　　4、Easy to install; welded using a hot-air gun, resulting in strong and reliable welds.

　　5、High resistance to chemical corrosion, suitable for specialized applications.

　　6、It has good malleability, making it easy and quick to work on fine details at the edges and corners.

Key Performance Indicators

Recommended Level 1 Waterproofing Design Plan

Scope of Application

　　It is primarily used for various types of roof waterproofing projects, including those in industrial and residential buildings, public buildings, and more:

●Internal-reinforced (P) membranes are suitable for mechanically fastened roof waterproofing systems;

●Backed (L) rolls are suitable for full-adhesive systems on substrate surfaces;

●Homogeneous (H) rolls are primarily used for detailing.

Construction Methods

Mechanical Fixation Method

　　Surface Preparation → Vapor Barrier → Installation of Insulation → Layout Marking → Installation of Waterproofing Membrane → Mechanical Fastening of Waterproofing Membrane → Hot-Air Welding of Overlaps → Detail Treatment → Quality Inspection and Acceptance

Full-Adhesion Method

　　Surface Preparation → Marking Out → Applying Specialized Adhesive → Laying Waterproofing Membrane → Welding Overlaps → Detail Treatment → Quality Inspection and Acceptance

Open-Laying and Capping Method

　　Surface preparation → Installation of waterproofing membrane → Hot-air welding of overlaps → Reinforcement of details → Quality inspection and acceptance → Installation of non-woven fabric → Weighting with gravel (or other weights)

Storage and Transportation

　　1、Products of different types and specifications should be stored separately and should not be mixed.

　　2、Rolls should be stored in a well-ventilated area protected from direct sunlight and rain. The storage temperature should not exceed 45°C.

　　3、When stored flat, rolls should be stacked no higher than 5 layers; when stored upright, they should be stacked in a single layer. Do not allow contact with acids, alkalis, oils, or organic solvents.

　　4、Prevent tilting or lateral pressure during transport; cover with a tarp if necessary.

5、Under normal storage conditions, the shelf life is 1 year from the date of manufacture.
