Introduction to the application of the"Duba Zhilou"system

　　"Duba Leakage Control System"is a comprehensive leakage control solution that integrates advanced materials,scientific design,and professional construction methods.Its core philosophy is"accurate diagnosis,eradication of lesions,and long-term protection",and it is widely applied in the following five key areas.

　　1.Underground engineering:

　　Solution:

　　For crack leakage,high-pressure grouting technology is employed to inject"Duba No.1"special polymer grout,achieving water-bearing operation,instantaneous water stoppage,and micro-expansion filling.

　　2.For large-area leakage,apply"Duba 2"high-elasticity and strong-adhesion grouting material to form a new waterproof layer on the upstream face of the structure,achieving self-repair and sealing of the original waterproof layer.

　　3.For weak links such as construction joints and deformation joints,the"two cuts and one block"treatment plan is adopted.Multiple precautions are taken to ensure dynamic sealing effect.

　　II.Industrial factory buildings:

　　Solution:

　　The construction process of applying"Duba"UV-resistant waterproof coating(one cloth with three coats)to the joints of metal roofs or leakage points on concrete roofs,through material curing,forms a continuous,seamless,elastic,and high tensile strength waterproof coating,effectively blocking the water infiltration path and achieving the goal of leakage control.It adapts to thermal expansion and contraction,and eliminates leakage caused by vibration.

　　III.Indoor space:

　　Solution:

　　The indoor leakage areas are treated using targeted minimally invasive leakage water management technology.A specialized small drill bit(with a diameter of 1-3mm)is used to drill holes and inject specific Baba grouting materials.Leveraging the expansion,curing,or chemical reaction characteristics of the grouting materials,cracks and pores are filled,cutting off the leakage water channels.A fully sealed waterproof layer is formed under the floor tiles,thus achieving the purpose of water stoppage and waterproofing.

　　IV.Building roof:

　　Solution:

　　Adopting the"Duba"roof waterproofing layer renovation scheme,using DFA high-performance non-cured rubber asphalt waterproof coating combined with elastomer modified asphalt waterproofing membrane,and incorporating a drainage board system,forms an integrated solution for waterproofing,drainage,and root resistance.This effectively eliminates the hidden dangers of water leakage.

　　5.Building exterior walls

　　Solution:

　　Using"Duba"transparent waterproofing agent for exterior walls,it endows decorative materials with excellent water repellency without altering the appearance of the exterior walls,achieving"breathable"waterproofing.

　　For cracked walls,first apply"Duba"flexible exterior wall waterproof putty and anti-crack mesh cloth for leveling and reinforcement,and then apply waterproof coating to form a rigid waterproof layer.
