Wat is het verschil tussen geotextiel 120 en 150 gr/m²?

Geotextiel 120 gr/m² is geschikt voor lichte infrastructuurtoepassingen zoals toegangswegen met beperkte voertuigbelasting tot 3,5 ton. Geotextiel 150 gr/m² biedt superieure treksterkte van 9 kN/m voor intensievere infrastructuurprojecten zoals parkeergarages en industriesites met zwaar voertuigverkeer tot 10 ton/m². Beide gewichten zijn BENOR-gecertificeerd en bieden waterdoorlatendheid van 110 l/m²s.

Wat is BENOR-certificering?

BENOR is Belgische kwaliteitscertificering die garandeert dat geotextiel doek voldoet aan strikte nationale normen voor treksterkte, waterdoorlatendheid en duurzaamheid. BENOR-producten zijn getest door onafhankelijke laboratoria en geschikt voor aanbestedingen bij overheidsopdrachten. Voor gemeentelijke projecten is BENOR-certificering vaak verplicht. DM Covering levert certificeringsdocumentatie voor indiening bij aanbestedingen.

Wat is het verschil tussen geotextiel en worteldoek?

Geotextiel is primair ontworpen voor infrastructuurtoepassingen: grondscheiding, drainage, filtratie en stabilisatie bij civiele projecten en wegenbouw. Het voldoet aan BENOR-normen voor aanbestedingen. Worteldoek is specifiek gericht op onkruidwering in tuintoepassingen. Voor tuinprojecten bekijk onze worteldoek collectie, voor infrastructuur is geotextiel de juiste keuze.

Wat is de waterdoorlatendheid van geotextiel?

Geotextiel van DM Covering heeft een waterdoorlatendheid van 110 l/m²s verticaal. Dit garandeert efficiënte waterafvoer en voorkomt wateraccumulatie in fundering. De capaciteit is 5-10x groter dan ontwerpvereisten bij normale regenval, wat veiligheidsmarge biedt bij piekbelasting door wolkbreuken.

Is geotextiel geschikt voor aanbestedingen?

Geotextiel 120-150 gr/m² van DM Covering is volledig BENOR-gecertificeerd en voldoet aan Belgische kwaliteitsnormen conform normering NBN EN ISO 10319. Dit maakt het geschikt voor aanbestedingen bij gemeentelijke en provinciale infrastructuurprojecten. DM Covering levert certificeringsdocumentatie en technische fiches voor indiening bij aanbestedingsdocumentatie.

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.

Frequently Asked Questions about Geotextiles

Geotextile 120 g/m² is suitable for light infrastructure applications such as access roads and site paving with limited vehicle loads of up to 3.5 tons. Its primary function is soil separation and drainage. Geotextile 150 g/m² offers superior tensile strength of 9 kN/m and mechanical robustness for more intensive infrastructure projects such as pavements, parking garages, and industrial sites with heavy vehicle traffic of up to 10 t/m².

Both weights are BENOR-certified and offer a water permeability of 110 l/m² for efficient drainage. For government tenders, we recommend 150 g/m² for long-term performance.

BENOR is a Belgian quality certification that guarantees that geotextile fabric meets strict national standards for tensile strength, water permeability, and durability. BENOR products have been tested by independent laboratories and are suitable for tenders in government contracts and infrastructure projects.

The label guarantees consistent quality and performance according to Belgian building regulations. BENOR certification is often mandatory for municipal projects. DM Covering provides certification documentation for submission to tenders.

Geotextiles and root cloth are related but not identical materials. Geotextiles are primarily designed for infrastructure applications: ground separation, drainage, filtration, and stabilization in civil engineering projects, road construction, and heavy-duty applications. They meet BENOR standards for tenders. Root cloth is a specific type of fabric designed for weed control in landscaping applications, under gravel, mulch, or paving. For professional landscaping projects and weed control, view our root cloth collection. For infrastructure, drainage, and civil engineering projects, BENOR-certified geotextiles are the right choice.

DM Covering's geotextile has a vertical permeability of 110 l/m²s. This ensures efficient water drainage through the fabric to underlying drainage or soil, prevents water accumulation in the foundation, and reduces pavement degradation due to frost damage.

The capacity of 110 liters per square meter per second is 5-10 times greater than the design requirements for normal rainfall. This provides a safety margin for peak loads caused by cloudbursts. For paved surfaces and parking garages, optimal drainage prevents undermining of the foundation.

DM Covering's 120-150 g/m² geotextile is fully BENOR-certified and meets Belgian quality standards for mechanical properties, hydraulic performance, and durability. This makes it suitable for tenders for municipal and provincial infrastructure projects.

The BENOR label guarantees a tensile strength of at least 9 kN/m, water permeability of 110 l/m²s, and consistent pore size in accordance with the NBN EN ISO 10319 standard. DM Covering provides certification documentation and technical data sheets for submission with tender documents. Contractors benefit from pre-approved products.
