Details of Specialized Construction Projects

Item Roof Waterproofing Project Building Insulation Project
Purpose Prevent penetration of rain and snow, protect building structure Improve indoor heat retention, reduce energy consumption, enhance living comfort
Main Materials Waterproofing membranes (SBS, APP, etc.), polyurethane coatings, sealants Insulation boards (XPS, EPS), rock wool, glass wool, insulation coatings
Construction Process    1. Base cleaning
   2. Leveling treatment
   3. Laying waterproofing membrane/applying waterproofing coating
   4. Joint treatment, edge sealing
   5. Protective layer covering		    1. Wall/roof cleaning
   2. Adhering/fixing insulation boards
   3. Steel mesh reinforcement (if needed)
   4. Surface treatment (plastering or coating)
   5. Joint and node treatment
Functional Characteristics Anti-leakage, moisture-proof, crack-resistant Thermal insulation, energy saving and emission reduction, improved comfort
Construction Period Typically 5–15 days (depending on area and complexity) Typically 7–20 days (depending on area and construction method)
Construction Difficulties Joint treatment, continuity of waterproofing layer, waterproof penetration points Thermal bridge treatment at nodes, thickness control of materials, coordination with structure
Common Problems Leaks, blistering, cracking Uneven insulation effect, hollowing, cracking, moisture condensation
Maintenance Cycle 5–10 years (membranes/coatings require regular inspection) 10–20 years (insulation boards generally have a long lifespan)
Typical Application Areas Roofs, balconies, terraces, basement slabs Exterior walls, roofs, floors, pipe wrapping
