Self-adhesive waterproofing membranes have different thickness specifications, mainly to meet different usage requirements and adapt to different construction environments.
Reasons for different thickness specifications Material properties: Membranes of different thicknesses are suitable for different environments and needs. For example, thicker membranes usually have better puncture resistance, abrasion resistance, weather resistance and aging resistance, can better resist external stress and extend service life.
Construction environment: Membranes of different thicknesses perform differently in high or low temperature environments. For example, thicker membranes are less likely to deform at high temperatures, but can better maintain their shape at low temperatures.
Use scenarios: Membranes of different thicknesses are suitable for different parts of the building. For example, thinner membranes are suitable for roof waterproofing, while thicker membranes are suitable for basements or underground projects.
Application scenarios of different thickness specifications 1.2mm to 2.0mm: Suitable for roof waterproofing, especially in high or low temperature environments, these thicknesses of membranes can provide better waterproofing effects.
2.0mm to 4.0mm: Suitable for waterproofing of concealed projects such as basements, subways, and tunnels. These thicknesses of membranes have better puncture resistance and abrasion resistance.
0.7mm to 2.0mm: Suitable for pre-paving/wet-paving waterproofing projects. These thicknesses of membranes can be firmly bonded with building materials such as cement to form a complete waterproof sealing system.
The impact of different thicknesses on waterproofing effects
Physical barrier effect: Thicker waterproof coating layers can provide stronger physical barriers, extend the penetration path of water, and increase the difficulty of penetration.
Resistance to external stress: Thicker coatings have better flexibility and tensile resistance, can better adapt to external stress, and reduce the possibility of cracking and breakage.
Durability: Thicker coatings usually have a longer service life, can better resist UV radiation and chemical erosion, and delay the aging process.
In summary, the different thickness specifications of self-adhesive waterproof membranes are designed to meet different usage requirements and adapt to different construction environments. Membranes of different thicknesses have their own advantages in physical barrier, resistance to external stress and durability.
