Geotextiles for Professional Infrastructure Projects
Professional geotextile fabric (120-150 g/m²) with BENOR certification for contractors and civil engineering projects requiring soil stabilization, drainage, and separation of soil layers in infrastructure. This permeable separation fabric acts as a filter layer between different soil types and prevents mixing in access roads, parking garages, paved surfaces, and industrial sites. Polypropylene geotextiles are available in weight categories of 120 g/m² for light infrastructure and 150 g/m² for heavier loads such as railways, dewatering, and granular drainage mats.
Tensile strength of 9 kN/m with elongation at maximum load of 45% longitudinal and 55% transverse guarantees mechanical robustness against ground movements and load variations. Water permeability of 110 l/m² vertical ensures efficient drainage and prevents water accumulation in paved areas. A thermal and mechanical bonding process results in superior performance per unit weight compared to traditional woven geotextiles. Available in widths of 2 m, 4 m, and 5.25 m with lengths of 10 m, 50 m, and 100 m for efficient installation over large areas without excessive seams.
Woven vs Nonwoven Geotextiles
Nonwoven geotextile fabric is thermally bonded and offers excellent filter and drainage properties for infrastructure projects. This variant is ideal for separating soil layers, protecting drainage systems, and as a filter layer in road construction. Woven geotextiles offer higher tensile strength and are suitable for soil stabilization under heavy loads. DM Covering supplies nonwoven geotextiles with BENOR certification, specifically developed for Belgian infrastructure standards and professional civil applications.
BENOR Certification & Hydraulic Properties
The BENOR label guarantees compliance with Belgian quality standards and performance criteria for professional civil applications and government project tenders. Consistent pore openings accommodate various soil types, from clay to sand, without clogging, filtering, or loss of permeability after installation. Water flow capacity, often several times greater than design requirements, increases the safety margin of drainage systems and prevents failure during peak rainfall.
Maintains hydraulic properties under pressure, soil layers, and vehicle loads up to 10 tons/m², making it suitable for access roads, parking garages, and industrial paving. Durable polypropylene resistant to biological degradation, chemical attack, and UV degradation in closed-pack soils. Life expectancy of 25+ years in closed-pack applications without UV exposure.
Geotextile Applications in Civil Projects
Access roads and pavements: Geotextiles as a filter layer under the foundation distribute loads and improve drainage of the roadbed. Separating the bearing layer from the underlying weaker soil prevents subsidence and pavement deformation in construction and infrastructure projects. Parking garages and industrial sites benefit from the separation between the bearing layer and the soil, reducing material use by up to 30%.
Railways and dewatering: A drainage layer around railway sleepers and ballast bed prevents subsidence and extends the maintenance intervals of railway infrastructure. Granular drainage mat filter layer protects drainage pipes from clogging with fine material and guarantees the long-term functionality of dewatering systems in buildings and sports complexes. Ponds and waterways: Protection of pond liner, separation of soil and water in professional water features.
