Floor-penetrating pipe collars are an item with a very high risk of leaking in construction projects. Why can you say that? Because the wire is the interface between different materials and concrete, the adhesion of concrete to those materials is not high.

Floor pipes commonly used in construction structures are metal pipes or PVC pipes. At the point of contact with concrete, these types of pipes always have certain gaps and that is the condition for leaks to attack your project.

Floor-penetrating pipes appear frequently in most construction projects and waterproofing the floor-penetrating pipes is also necessary to prevent leakage through this location. When constructing waterproofing for pipes passing through the floor, you need to pay attention to the following issues:

Requirements for the concrete surface before waterproofing the pipe neck through the floor:

– Remove and remove obstacles: formwork, wood, steel, debris, standing water, etc.

– Concrete defects such as pockets, pores, etc. should not be covered by cement mortar before waterproofing treatment.

– Chisel and use a cutter or wind stone to cut the excess steel whiskers on the concrete floor to a minimum depth of 2cm compared to the concrete surface.

–Water supply and drainage pipes penetrating concrete or technical boxes should be located and installed with mortar or concrete filling at least ½ of the concrete thickness. Technical boxes in toilet areas (if any) and boundary walls should be built and plastered with cement mortar to a minimum height of 30 cm to reinforce and waterproof synchronously with the concrete floor.

– Do not use water mixed with powdered cement to soak or apply cement slurry to maintain concrete items before applying waterproofing treatment.
