  • Excellent solution
    for the building sector
    ARGEX® is a natural, ecological, long-lasting,
    non-combustible and inert product.
  • Pre-fabricated Concrete
    ARGEX® expanded clay is used extensively in
    manufacturing lightweight blocks and pre-moulded panels.

    Lightness, mechanical resistance, thermal insulation, acoustical insulation and fire resistance
    are some of the properties of ARGEX® pre-fabricates
  • Geotechnical
    ARGEX® expanded clay has been widely applied on the main geotechnical works
    of the last few years throughout the Iberian Peninsula.

    This is an economical, practical and reliable solution to resolve geotechnical problems.
  • ARGEX® Expanded Clay
  • Flora and Landscaping
    ARGEX® is recommended for work in flora
    and landscaping, such as:
    Green roofs
    Horticulture (Agriculture and gardening)
    Substrate and covers of gardened areas
    Terraced gardens and flower boxes
    Cultivated beds
    Hydroculture or hydroponics
Wide range of applications:
ARGEX® allows greater energy savings, thermal and acoustical comfort in buildings.
ARGEX® expanded clay is an economical, practical and reliable solution to resolve geotechnical problems.
ARGEX® is recommended for biofiltration in wastewater treatment plants WWTP.
On roof gardens encourages an increase in biodiversity, contributing to a more sustainable ecosystem.

Product
Argex expanded clay is a lightweight spherical-shaped aggregate, with an internal structure made of ceramic foam with micropores, and a rigid and sturdy surface.
The different granule sizes may be provided on: 50-litre bags, BigBags of 1,5 m³, BigBags of 3,0 m³ and Bulk.
Aggregate sizes

Mortars and lightweight plasters with good thermal performance and fire resistant. The mechanical and physical properties of the aggregate make it suitable for use in prefabricated elements with special features.

Lightweight concrete with good thermal and acoustic behaviour and structural lightweight concretes for special projects and for rehabilitation works.

Lightweight concrete filling for insulation and regularization of floors in buildings, shape layers on roofs, bridges and viaducts.

Filler solutions with good thermal and acoustic behaviour, such as insulation and regularization of floors in buildings, form layers in roofs and for filling air-boxes in double walls.
