Product Introduction

Description

Application

The Blue Seal Waterproofing Rubber Membrane is suitable for various applications. The product can be used in roofs, foundations, tunnels, and underground structures. It is ideal for use where traditional asphalt waterproofing is not practical. The product is also suitable for use in areas where temperature fluctuation is common. It has excellent adhesive properties and can be applied directly to various types of substrates, including concrete, metal, and wood.

Properties

The Blue Seal Waterproofing Rubber Membrane is designed to withstand harsh weather conditions. It has excellent resistance to UV radiation, oxidation, and chemical exposure. The product is also flexible and can easily accommodate building movement without compromising the waterproofing system's integrity. The blue aluminum foil layer provides protection against heat penetration, ensuring optimal temperature regulation within the building. The product has a high shear strength, ensuring that it adheres firmly to the substrate. It is also highly resistant to puncture, providing long-term protection to the building's foundation.

Construction Requirements

Before installing the Blue Seal Waterproofing Rubber Membrane, the substrate must be thoroughly cleaned and prepared. The substrate should be free of debris, dust, and any other materials that can compromise the adhesion of the product. The temperature of the substrate should be at least 5°C above the dew point. The product should be stored in a cool and dry place to ensure optimal performance. During installation, the membrane should be rolled out and cut to size. The backing material should be removed, and the membrane should be carefully placed on the substrate, ensuring that there are no air pockets. The membrane should be firmly pressed in place, ensuring that it adheres to the substrate.

Specification

1mx20m (20M2/Roll), 1.2mm or 1.5mm thickness. Length can be customized.
