croatia Geosynthetic Vertical Permeability Testing Apparatus
Product Description
1. Overview
The vertical permeability tester is a horizontal constant head testing instrument designed and manufactured according to the requirements of the Ministry of Transport's newly released "Test Specifications for Geosynthetics in Highway Engineering JTG E50-2006". It is suitable for testing the vertical permeability performance of various geotextiles and composite geotextiles with water permeability under a constant water head.
- Principle
Water flow (mm/s) perpendicular to the geotextile plane under a unit hydraulic gradient
