It is generally not recommended to mount a panel directly on concrete in a residential basement where the walls are 2-3 meters below ground level, as it can lead to moisture and mold issues. Here are the reasons and recommended做法s: Moisture buildup

Concrete walls below ground level are exposed to moisture from the surrounding soil and groundwater. This moisture can penetrate the concrete and reach the back of the panel, leading to mold growth, corrosion, and damage to the panel.

Vapor barrier

Concrete is a porous material that allows moisture vapor to pass through. If a panel is mounted directly on concrete without a vapor barrier, the moisture vapor can condense on the back of the panel, creating a breeding ground for mold.To prevent these issues, it is essential to use a sill gasket and plywood behind the panel to separate it from the concrete wall. Here are the recommended steps:1.

Install a sill gasket

Apply a continuous bead of sill gasket along the bottom of the panel, where it will come into contact with the concrete wall. This gasket will act as a barrier to moisture and prevent it from penetrating the panel.2.

Attach plywood to the concrete wall

Cut a piece of plywood to the size of the panel and attach it to the concrete wall using masonry screws or construction adhesive. The plywood will provide a moisture barrier and a solid base for the panel to be mounted on.3.

Mount the panel: Mount the panel on the plywood using appropriate fasteners, such as panel screws or nails. Ensure that the panel is level and securely attached to the plywood.By following these steps, you can effectively separate the panel from the concrete wall and prevent moisture and mold issues.
