Where does the DPC not appear to be provided?
At the places where the doors open, it is not something that should be offered. The highest level of the DPC should be at the same level as the finished floor level that was designed. Because DPC is made of cement concrete, it needs to be cured with water for seven days. Once it’s completely dry, a layer of bitumen with a grade of 85/25 should be spread evenly over the top of the surface.

Clear drawings and the design should be provided for intricate junctions, and premade cavity trays should be used.
Where in relation to the DPC do weep holes fall?
Bricklayers from MyBuilder have provided 8 responses. There is not typically a cavity tray at the DPC level, with the exception of situations in which something like a Radon Barrier is necessary. This barrier should overlap the inner wall, the cavity, and the outside wall. You would then want a cavity tray above with weep holes to complete the installation.
Where do horizontal and vertical DPC differ from one another?
Whereas a horizontal DPC works to prevent moisture from traveling upward from the ground via your walls, a vertical DPC is designed to prevent water from moving laterally across walls and surfaces that are likely to come into touch with one another. When walls of this kind are being rebuilt, we refer to the process as “returning” the walls.
