Visual and workmanship inspection under D65 illumination — systematic examination for holes, thin spots, foreign inclusions, and coating defects against agreed acceptance criteria and master reference samples.

Mechanical and Interface Performance Testing for Single Rough Surface Geotextiles

Tensile strength and elongation at break per ISO 10319 and ASTM D4595 — wide-width strip specimens are pulled to failure in machine and cross directions to measure the ultimate tensile strength and elongation, verifying the geotextile withstands installation stresses and long-term tensile loads in reinforcement applications.
Grab tensile strength per ASTM D4632 — for quality control and specification conformance, the grab tensile strength of the single rough surface geotextile is measured using a defined jaw configuration.
CBR puncture resistance per ISO 12236 and ASTM D6241 — a plunger is pushed through the geotextile to measure the puncture force required for failure, simulating the stress from sharp stones, construction equipment, and backfill placement.
Static puncture resistance per ISO 12236 and ASTM D4833 — a pointed probe is driven through the material to determine the resistance to localized penetration by stones and debris.
Tear strength by trapezoid and tongue methods per ISO 10319 and ASTM D4533 — the force required to propagate a tear from an initial slit is measured to ensure the geotextile resists damage during installation and service.
Interface friction and direct shear testing per ASTM D5321 and ISO 12957-1 — the single rough surface geotextile is sheared against soil, sand, or geomembrane in a large direct shear box to measure the interface friction angle and adhesion, verifying the textured surface provides the required slope stability and anchorage performance.
Pullout resistance and anchorage capacity per ASTM D6706 — the geotextile is embedded in compacted soil and pulled out to measure the interface friction and the force required to extract the reinforcement, providing design data for retaining walls and steep slopes.
Creep and long-term tensile behavior per ISO 13431 and ASTM D5262 — sustained tensile loads are applied to the single rough surface geotextile for extended periods, and the time-dependent elongation is measured to predict long-term deformation under constant load in reinforced soil structures.

Hydraulic and Filtration Performance Testing for Single Rough Surface Geotextiles

Water permeability perpendicular to the plane per ISO 11058 and ASTM D4491 — the volumetric flow of water through the geotextile under a defined head is measured to determine the permeability coefficient and the permittivity, ensuring the material provides the required drainage and filtration function without excessive head loss.
Water flow capacity in the plane per ISO 12958 and ASTM D4716 — for single rough surface geotextiles used as drainage layers, the in-plane flow capacity is measured under defined hydraulic gradients and normal loads to verify the material can transmit water along the plane to drains and outlets.
Apparent opening size and pore size distribution per ISO 12956 and ASTM D4751 — the geotextile is sieved with graded glass beads to determine the filtration opening size, ensuring the material retains soil particles while allowing water to pass without clogging.
Clogging and gradient ratio test per ASTM D5101 — the long-term filtration behavior of the single rough surface geotextile is evaluated by measuring the change in permeability and the gradient ratio under cyclic flow with a soil-geotextile system, predicting the risk of clogging and the service life of the drainage function.

Heavy metals and extractable substances per EN 13249 and ASTM C1116 — the geotextile is leached with water and the extract is analyzed for heavy metals and other regulated substances to ensure it does not contaminate soil, groundwater, or concrete when used in construction.
Formaldehyde and volatile organic compound emissions per ISO 16000-3 — chamber emission testing verifies that the single rough surface geotextile does not release harmful VOCs or formaldehyde into the indoor air of covered or enclosed installations.
