The main differences in waterproofing membranes are in terms of material, thickness, and scope of use.Common waterproofing membranes on the market include asphalt waterproofing membranes, polymer waterproofing membranes, and coating waterproofing materials, which differ in material, performance, and application scenarios.
Material differences:
Asphalt waterproofing membranes: Mainly made of asphalt and fiber materials, with good corrosion resistance and aging resistance.
Polymer waterproofing membranes: Made of materials such as polymers and modified asphalt, with good toughness and temperature resistance.
Coating waterproofing materials: Made of materials such as polymers, asphalt or chloroprene rubber, suitable for waterproofing repairs on roofs, foundations, and other parts.
Thickness differences:
Polymer waterproofing membranes are thinner, while Asphalt waterproofing membranes are thicker.
Scope of use differences:
Polymer waterproofing membranes are mostly used for flat roof waterproofing, basement walls, underground passages, etc. of buildings.
Asphalt waterproofing membrane can be used for waterproofing in various building parts.
Advantages, disadvantages and applicable scenarios of different types of waterproofing membranes SBS waterproofing membrane:
Advantages: Good waterproofing performance, can effectively resist rainwater penetration, service life of about 15 years, suitable for cold areas in the north.
Disadvantages: Short service life when exposed, about 4 years, and the construction level has a greater impact.
Applicable scenarios: Suitable for cold areas in the north and buildings with higher waterproofing requirements.
TPO waterproofing membrane:
Advantages: Light weight, good weather resistance, service life of up to 30 years, suitable for complex roof shapes.
Disadvantages: High requirements for construction methods, and it is necessary to ensure that the bonding is firm when fully glued.
Applicable scenarios: Suitable for roof waterproofing projects that require long-term durability.
PVC waterproofing membrane:
Advantages: Good overall performance, service life of about 10 years.
Disadvantages: Not environmentally friendly, plasticizers will be released over time, affecting durability.
Applicable scenarios: Applicable to building roofs that require better waterproofing effects.
Polyurethane waterproof coating:
Advantages: Good waterproofing performance, but cannot be used exposed and has a short lifespan.
Disadvantages: Lifespan is less than 2 years when exposed.
Applicable scenarios: Often used in conjunction with other waterproof membranes to enhance the waterproofing effect.
