Geomembrane Impermeability Tester

Hydrostatic resistance, permeability, and burst strength testing to 2.5 MPa.

A geomembrane impermeability tester measures how well a barrier resists water passing through it, either as a pressure threshold or a flow rate. Labs qualify geomembranes, geotextiles, and composite liners before they reach landfills, canals, tailings ponds, and tunnels. Methods follow ASTM D5385 and ISO 811 practice. Pressure ratings on this range reach 2.5 MPa.

Qualitest offers this family in two forms. The GIT GM handles static water pressure on a dedicated frame, with an option that adds hydrostatic burst strength. The GIT A consolidates four test methods, adds permeability coefficient measurement, and generates reports directly on the instrument. Both share a 0.5 pressure accuracy class and automatic pump water supply.

Why Choose Qualitest for Your Geomembrane Impermeability Tester

Qualitest North America supplies testing and measurement equipment to laboratories, quality teams, and manufacturers, backed by responsive technical support and calibration service. The geomembrane impermeability 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

Impermeability testing supports any project where a barrier layer carries a containment obligation over its service life.

  • Landfill and Waste Containment: qualifies base liners and cap systems for leachate head resistance and seepage rate before construction.
  • Water Conservancy and Hydraulic Works: verifies liners for canals, dams, reservoirs, and irrigation channels under sustained head.
  • Mining and Tailings Facilities: evaluates barriers for heap leach pads and tailings ponds that hold process solution for years.
  • Highway and Railway Engineering: checks geomembranes and geotextiles used in subgrade drainage, embankment protection, and tunnel waterproofing.
  • Building Waterproofing: measures water penetration resistance of membranes specified for basements, foundations, and roof assemblies.
  • Geosynthetics Manufacturing QC: runs batch release testing on smooth, textured, and geotextile-backed production lines.
  • Third-Party Laboratories: delivers documented barrier performance data for certification, material qualification, and dispute resolution.

Geomembrane Impermeability Tester Range

Three orderable configurations cover the range from single-method testing to a full automated barrier program.

ModelTest MethodsTest Cell SizeDescription
QualiGTX™ GIT GM (Hydrostatic Resistance)Geomembrane static water pressure resistanceø30.5 mmA dedicated hydrostatic frame with stainless steel clamping, 10-inch touchscreen, and automatic timing. Suits labs that run one test method at high volume and want a straightforward, repeatable pressure-hold instrument.
QualiGTX™ GIT GM (Dual-Function)Static water pressure resistance and hydrostatic burst strengthø30.5 mmThe same frame with an adjustable pressurization rate, which lets one unit run both pressure-hold and rupture tests. Suits labs that report burst strength alongside water tightness without buying a second instrument.
QualiGTX™ GIT A (Automatic)Geotextile hydrostatic resistance, geomembrane hydrostatic resistance, permeability coefficient, burst strengthø30.5 mm and ø200 mmA microcomputer-controlled system with dual test cells, a perforated support plate for large specimens, temperature monitoring from 5°C to 60°C, and automatic report generation. Suits labs covering the complete anti-seepage program on one platform.

How to Choose the Right Geomembrane Impermeability Tester

  • For a single test method at high throughput: choose the GIT GM hydrostatic resistance configuration for the simplest operation and lowest cost of entry.
  • For labs reporting both water tightness and rupture pressure: choose the GIT GM dual-function configuration, which adds an adjustable pressurization rate for burst testing.
  • For permeability coefficient work: choose the GIT A, the only model with temperature monitoring, which matters because water viscosity shifts the measured coefficient.
  • For large-area geotextile specimens: choose the GIT A for its ø200 mm cell and perforated support plate; the ø30.5 mm cell alone limits you to small-diameter membrane specimens.
  • For labs needing digital records: choose the GIT A for automatic report generation and data upload rather than manual transcription.
  • For a mixed material portfolio: choose the GIT A, which handles geotextiles and geomembranes on one frame instead of splitting work across instruments.
