There are various topics related to waterproof materials and construction. In fact, from the source of waterproofing, water leakage actually comes from “holes” and “seams”. you ‘re right. So the question that all waterproofing must consider is what materials and construction techniques should be used to prevent water from entering through the “holes” and “seams”. Of course, this is just a basic concept in theory.
The reality is that when we do waterproofing for any subject, we need to consider more factors besides the waterproofing effect. For example, whether the appearance is beautiful, the durability of waterproof effect, safety and environmental factors, cost factors, and so on.
Taking roof waterproofing as an example, there are three basic knowledge that we need to understand:
- The essential layer of roof waterproofing is intermittent waterproofing, which is directly affected by natural environmental conditions. So the characteristics of the roof waterproof layer must be dynamic and subject to changing conditions, and a certain durability period should be considered.
- The roof waterproof layer is a waterproof building attached to the foundation layer. Generally speaking, the current foundation leveling is still mainly based on cement mortar and fine aggregate concrete. Therefore, the “holes” and “joints” on the foundation leveling are the key to dealing with roof seepage, water breakthrough, and delamination phenomena. Based on years of theoretical and practical experience in the industry, the setting of roof waterproofing layers should at least include three levels: base sealing layer, main waterproofing layer, and progressive reinforcement layer, in order to form a relatively complete set of waterproofing layers.
- The role of grassroots blockade layer, main waterproof layer, and progressive enhancement layer
