Method to determine the resistance of geosynthetics to penetration by steel cone dropped from a fixed height, as a simulation of dropping sharp stones on their surface. Generally applicable to all geosynthetics. However, the test principle may not be applicable to some types of products. The specimen is clamped between two steel rings. A steel cone (45° tip angle, 1000 g) is dropped from a height of 500 mm onto the centre of the specimen. The degree of penetration is measured by insertion of a graduated cone into the hole.

Note: - Electrically cone release facility also available

• On Floor Modal
• Mechanical operated (Electrical release modal also available)
• Sample Size 150 mm (Test able)
• Total Drop height 500 mm ( ± 5 mm Adjustable as per sample thickness)

  3. Having marking of 1 mm interval for better result

Permeability of a geotextile must be substantially greater than that of the protected soil, so that water can pass freely from the soil through the fabric without build up of hydro static pressure. A high value of the permeability of the geotextile also infers that partial clogging will not reduce the permeability. The constant head test is carried out using a head of 50 mm of water.

Essential Accessories

• Overhead Tank
• Loading unit, 300-kPa capacity
• Cross Permeability Apparatus

These test methods cover procedures for determining the hydraulic conductivity (water permeability) of geotextiles in terms of permittivity under standard testing conditions, in the uncompressed state. Included are two procedures: the constant head method and the falling head method.

In Constant Head Test:- A head of 50 mm water is maintained on the geo textile throughout the test. The quantity of flow is measured versus time. The constant head test is used when the flow rate of water through the geotextile is so large that it is difficult to obtain readings of head change versus time in the falling head test.

In Falling Head Test:- A column of water is allowed to flow through the geo textile and reading of head changes versus time is taken. The flow rate of water through the geo textile shall be slow enough to obtain accurate readings.

Sample Size: - 50 mm
Head can be maintain of the sample : up to 40 cm
Suitable for both type of test :- Constant Head and Falling Head.

These test methods cover procedures for determining the hydraulic conductivity (water permeability) of Geotextile under standard testing conditions, in the uncompressed state. The system analyzes the rate of water flow through the specimen as a function by means of a two cylinder- system.

Measurement results are presented on the scale numerically, which is the velocity at a hydraulic height difference of 50 mm.
