PLASTIC TUBES

MAPLAD offers a complete range of plastic solutions for geotechnical applications, focusing on wells and hydrogeological monitoring, drainage and consolidation injections, with high-performance technical PVC pipes.

PVC pipes and filters for wells and piezometers

Threaded rigid PVC pipes and filters are designed for the construction of artesian wells, piezometers and groundwater monitoring systems. The quality of the extrusion and the care taken in drilling guarantee robustness, stability over time and excellent hydraulic performance.

  • Advantages
    • High mechanical resistance and resistance to ground pressure, with threaded joints that ensure hydraulic sealing along the column.
    • Lightweight and easy to handle, making it easy to handle and install even in deep holes.
    • PVC suitable for contact with drinking water and food liquids, in compliance with the main regulations.
  • Applications
    • Construction of wells for drinking water, irrigation, and industrial use.
    • Piezometers for monitoring the level and quality of groundwater.
    • Filters for wells and sub-horizontal drainage in hydrogeological and environmental interventions.
Drainage pipes and geotechnical plastic pipes for monitoring and consolidation

  • MAPLAD offers PVC drainage pipes and other plastic elements for controlling pore pressure and monitoring ground movements. The range includes grooved drainage pipes, sonic test pipes and plastic linings for measuring instruments, developed to operate in complex terrain and aggressive environments.

    • Advantages
      • High chemical resistance to aggressive groundwater, salts and washing treatments over time.
      • High drainage efficiency thanks to grooves calibrated according to the grain size of the soil and the large open surface.
      • Compatibility with major geotechnical equipment and ease of installation to reduce construction site times and costs.
    • Applications
      • Subhorizontal drainage for slope stabilization and reduction of pore pressure.
      • Linings for inclinometers and sonic testing tubes in the testing of piles, diaphragm walls and foundation structures.
      • Plastic solutions for geotechnical monitoring in road, railway, and underground structures.
Valved tubes for grout injections

PVC sleeve valve pipes are specifically designed for the controlled and selective injection of cement grout and special mixtures. The pipe is perforated at regular intervals and equipped with external elastic rings that act as non-return valves, allowing work to be carried out on individual levels along the hole.

  • Advantages
    • Precise control of the injection, with opening of only the affected sections and limitation of the dispersion of the coulis in the soil.
    • Possibility of performing repetitive and selective injections on the same hole, modulating volumes, pressures and mixtures over time.
    • Suitable for high pressures, suitable for deep consolidations, loose or cracked soils and work in sensitive urban areas.
    • Plastic material that can be easily shattered in the event of subsequent mechanical excavation, without damaging the tools.
  • Applicazioni
    • Soil consolidation through permeation and compensation injections under buildings, foundations and infrastructure.
    • Pre-consolidation of excavation faces in tunnels and underground works, from surface or pilot tunnels.
    • Iniezioni su micropali, tiranti e opere di sostegno per migliorare l’aderenza terrenoboiacca e la capacità portante.
