Fine sand and mineral aggregate are two common fillers used in waterproofing membranes, each serving different functions in different applications.
First, fine sand is a relatively fine filler with excellent filling properties and water permeability. It is typically used in applications requiring high water permeability, such as in roofing membranes, where it can enhance the permeability of the roof. Furthermore, fine sand has excellent compaction properties, effectively filling small gaps and improving the overall performance of the waterproofing layer.
Mineral aggregate, on the other hand, is a larger filler with excellent compressive and abrasion resistance. It is typically used in applications requiring high strength and wear resistance, such as in basement waterproofing membranes, where it can reinforce the waterproofing layer and enhance the overall strength and stability of the structure.
In summary, the main differences between fine sand and mineral aggregate in waterproofing membrane applications lie in their water permeability, strength, and wear resistance. Choosing the appropriate filler based on specific application requirements can effectively improve the performance of the waterproofing layer, extend its service life, and ensure the safety and stability of the building structure. I hope that everyone will choose suitable fillers when using waterproof materials to provide better protection for the building's waterproofing project.
