Barlavento Landfill

The work included:

- Earthworks to shape the terrain for the creation of the new cell;

- Implementation of the waterproofing system and technical networks;

- Excavation for the extension of the leachate treatment lagoon.

Due to the high complexity of the project, a diverse set of specific tasks was required, of which we highlight the following:

• Clearing and stripping of the intervention area;

• Earthworks to shape the terrain for the confinement cell;

-Implementation of the waterproofing system for the base and slopes of the two compartments, consisting of:

.Passive Barrier - a 0.50 m layer of soil, reinforced on top with bentonite geocomposite;

.Active Barrier - a 2.0 mm thick HDPE geomembrane, protected on top by non-woven geotextile in the base area of the cell;

-Drainage mineral layer at the base of the cell, with a thickness of 0.5m;

-Leachate drainage system;

-Rainwater drainage system;

-Subsurface water drainage system;

-Cell degassing system;

-Access roads to the base of the compartments and perimeter circulation around the cell;

-Fire network;

-Service network;

-Electricity distribution and lighting network;

-Groundwater monitoring system.
