Landfill Solutions
Landfills are veritable organisms with a life of their own. Among civil engineering projects, they are undoubtedly among the most complex and sophisticated . Their environmental impact requires managing a multitude of extremely diverse situations, while delicately handling the material they handle: waste.
Since the 80s, landfill design has required compliance with specific regulations—updated by Legislative Decree No. 36 of January 13, 2003 —designed to improve the stability of these structures.
The Legislative Decree provides for measures, procedures and guidelines capable of preventing and reducing the negative repercussions of waste on the environment.
Geosynthetics for landfills
Landfill legislation provides that the competent local authorities can approve alternative design solutions , characterised by thicknesses lower than those established, provided that they guarantee performance equivalent to those resulting from the adoption of the foreseen thicknesses.
This is why an increasing number of local administrations, since the approval of the legislative decree, have adopted stratigraphies that provide for the use of geosynthetics for landfills. In Sineco International offers specific systems for the stability and drainage of landfills, with technical and economic advantages.
- Technical benefits: through the use of geosynthetics in natural materials, performances equal to or superior to those foreseen by the decree are ensured. This is useful for:
- reduce the loads on the waste body in favor of better stability of the landfill;
- reduce its final height and limit the performance uncertainties arising from the use of common natural materials which have a non-homogeneous nature.
- Economic benefits: by reducing the thickness of the base and cover stratigraphy, useful volumes are freed up for waste disposal, limiting the costs for the supply and transport of inert materials. Furthermore, set-up times are reduced and, in relation to the quality control and characteristics of industrial products, consistent performance can be guaranteed.
Our products for landfills
SINDRAIN
A mat composed of a three-dimensional structure of polymer monofilaments and geotextile filters. It boasts high drainage capacity and guarantees the health, longevity, and safety of the structure in which it is installed.
SINMAT
Three-dimensional geomat made of polymeric monofilaments useful for preventing erosion phenomena , avoiding the leakage of liquids and/or sewage, as well as improving the containment of the structure to which it is placed.
They are both products geosynthetics specific for promote landfill stability.
Long-lasting and easy to install, they are an excellent alternative to the granular materials required by law.
La combination of geosynthetics SINDRAIN (for drainage) and SINMAT (anti-erosion) facilitate the flow of sewage on the bottom of the landfill, perimeter drainage in trenches, surface drainage of rainwater and gases and water disposal. Also ideal for containment and reinforcement works.
Applications of our geosynthetics for landfills
Geosynthetics for landfills Sineco International are recommended for the implementation of controlled landfill projects, in the context of civil engineering. Among the most important applications:
Geosynthetics for landfill stability
Specific solutions to strengthen the structure , expanding the functions of
protection, separation, filtration, drainage and barrier, avoiding erosion and slipping that are harmful to the soil and the environment.
Geosynthetics for landfill containment and consolidation
Elements applicable to soil and foundations to increase the usable volume of the landfill. Useful for reducing the amount of soil required for embankments, increasing the stability and safety of landfills, and preventing waste—including solid waste—from dispersing into the environment.
Geosynthetics for drainage of liquids, gases and sewage from landfills
Systems designed to facilitate the drainage of liquids, gases, and wastewater while maintaining the hydraulic head. Ideal for maximizing waste control and preventing spills.
