Waterproofing and Protection Board Installation on Tunnel Walls vlog

In this vlog, I will be showing you how to waterproof and install protection boards on tunnel walls. This is a crucial step in the construction of any tunnel, as it helps to protect the walls from water damage and other forms of deterioration.

Step 1: Prepare the Tunnel Walls

The first step is to prepare the tunnel walls for waterproofing. This involves cleaning the walls and removing any loose debris. Once the walls are clean, you will need to apply a primer to help the waterproofing membrane adhere to the surface.

Step 2: Apply the Waterproofing Membrane

Once the primer is dry, you can apply the waterproofing membrane. This is typically done using a roller or brush. Be sure to apply the membrane evenly and to avoid any gaps or bubbles.

Step 3: Install the Protection Boards

Once the waterproofing membrane is dry, you can install the protection boards. These boards are typically made of PVC or other durable materials. They are fastened to the walls using screws or nails.

Step 4: Finish the Installation

Once the protection boards are in place, you can finish the installation by caulking any gaps between the boards and the walls. You may also want to paint the boards to match the surrounding environment.
