Application: Tunels, highways
Surface Preparation
The surface of the tunnel walls and floor need to be cleaned and prepared for the application of the EVA waterproofing membrane. This may involve removing any existing coatings, smoothing out any rough areas, and ensuring that the surface is dry and free of debris.
Primer application
A primer is typically applied to the prepared surface in order to promote adhesion between the surface and the EVA waterproofing membrane. The primer may need to cure for a specified period of time before the next step can be taken.
Membrane Installing
The EVA waterproofing membrane is then applied to the prepared and primed surface using an adhesive or heat-welding method. The membrane is typically rolled out and cut to fit the dimensions of the surface, with care taken to ensure that it is installed without any wrinkles or bubbles.
Seaming
The seams between adjacent sheets of EVA waterproofing membrane need to be sealed in order to prevent water from seeping through. This may be done using heat welding or by applying a separate sealing tape.
Backfilling
Once the EVA waterproofing membrane has been installed and inspected, the tunnel can be backfilled with soil or other materials as necessary.
