Geotextile Cone Drop Testers

Geotextile Cone Drop Testers | EN ISO 13433 Dynamic Perforation Testing

Geotextile cone drop testers measure how well geosynthetic materials resist penetration by a steel cone released from a fixed height, following the dynamic perforation method defined in EN ISO 13433. The technician clamps a specimen, drops a 1 kg cone from 500 mm, and reads the diameter of the hole it leaves. Smaller holes indicate tougher fabric.

Qualitest supplies three frames built on identical test geometry: an automatic station for production throughput, a manual unit for general laboratory work, and a compact model for constrained floor plans. Every version carries the 45° stainless steel cone, the 150 mm clamping ring, and the graduated measuring cone the method calls for.

Why Choose Qualitest for Your Geotextile Cone Drop Tester

Qualitest North America supplies testing and measurement equipment to laboratories, quality teams, and manufacturers, backed by responsive technical support and calibration service. The Geotextile Cone Drop Tester range is built for reliable, standards-driven results, so you can source confidently from a single partner. Our team helps you match the right configuration to your samples, applicable standards, and throughput, then supports you through installation and beyond.

Applications

Cone drop testing supports material approval wherever geotextiles go into the ground beneath coarse fill.

Geosynthetic Manufacturing: verifies perforation resistance batch by batch across woven, nonwoven, and needle-punched product lines.
Geomembrane Protection Layers: ranks cushion geotextiles that shield liners from angular stone in landfill capping and basal lining systems.
Road and Highway Construction: qualifies separation and stabilization fabrics laid on soft subgrade before the first aggregate lift.
Installation Damage Quality Control: screens delivered rolls on site, catching material that would perforate during placement.
Erosion Control and Hydraulic Works: tests filter fabrics installed beneath riprap, gabions, and channel armoring.
Railway and Ballast Applications: evaluates fabrics that sit directly under angular track ballast.
Testing and Certification Laboratories: generates dynamic perforation data for project submittals and CE documentation packages.

Geotextile Cone Drop Tester Range

All three models share the test geometry that governs result accuracy, so the choice comes down to automation level and available floor space.

Model Comparison

Model	Operation	Dimensions (W × D × H)	Net Weight	Description
QualiGTX™ CDT A	Automatic lift, release, and clamping	700 × 620 × 1360 mm	120 kg	Touchscreen-controlled station that raises the cone, releases it, and clamps the specimen without operator input. The rigid frame absorbs recoil across repeated drops, which suits production QC and high sample volumes.
QualiGTX™ CDT M	Manual lift and release	600 × 300 × 1500 mm	45 kg	Hand-operated frame with a latch-set drop position and manual clamping ring. Needs no power supply or software, so it suits materials labs, teaching labs, and site laboratories running moderate volumes.
QualiGTX™ CDT C	Manual lift and release	450 × 350 × 1500 mm	45 kg	Same manual mechanism in the narrowest frame of the range. The 450 mm width fits wall runs and aisle ends in laboratories where floor area is already committed.

How to Choose the Right Geotextile Cone Drop Tester

For production quality control and high throughput: choose the CDT A, where automatic lift, release, and clamping remove operator-to-operator variation across long test runs.
For general laboratory and site testing: choose the CDT M, which delivers the full method geometry with no power or software to commission.
For laboratories short on floor width: choose the CDT C, the narrowest frame at 450 mm, with the same manual operation as the CDT M.
For labs without electrical or pneumatic services: choose either manual model, since both run on mechanical action alone.
For repeatability across many operators: choose the CDT A, because automatic clamping applies the same grip pressure on every specimen.
