Leister EXAMO 100 Geomembrane Weld Seam Tester

The Leister EXAMO 100 is a compact, cordless-operated weld seam peel testing instrument designed for on-site destructive testing of geomembrane weld quality in civil engineering applications, accepting specimens up to 25 mm wide and 3 mm thick and delivering a constant tensile speed for reproducible results without external power supply.

On-Site Weld Seam Quality Verification for Geomembrane Civil Engineering Projects

Geomembrane installations in landfill containment, reservoir lining, canal sealing, and environmental barrier construction rely on weld seam integrity as the primary assurance of system performance. When a weld fails in service, the consequences – leakage, contamination, structural compromise, and contractual liability – are disproportionate to the cost of the verification that could have identified the defect at installation. Yet on large civil engineering sites across Oman and the GCC, practical barriers consistently reduce the frequency of weld testing: distance from power sources, the time cost of transporting specimens to laboratory-grade equipment, the inconsistency of improvised field testing rigs, and the absence of a purpose-built instrument that can be operated by one person anywhere on site.

The EXAMO 100 is designed to remove those barriers. Its cordless drill operation eliminates cable dependency. Its tool-free clamping mechanism reduces setup to seconds. Its constant tensile speed – controlled by the cordless drill rather than by operator effort – delivers the repeatability that meaningful quality assurance requires. The result is a peel testing instrument that civil engineers will use more frequently because using it no longer competes with productive site time – and where testing frequency increases, overall weld quality follows.

EXAMO 100 Testing Capabilities and Field Engineering Features

• Cordless Drill Operation: The EXAMO 100 is driven by a standard cordless drill connected via the included bit adapter, eliminating dependence on a mains power supply and allowing peel testing to be conducted at any point on the geomembrane installation without cable routing or generator access.
• Constant Tensile Speed for Reproducible Results: The cordless drill drives the pulling mechanism at a consistent speed throughout the peel test, removing the operator variability that undermines manual tensile testing methods and producing results that are directly comparable across multiple test locations and operators.
• Tool-Free Specimen Clamping: An innovative clamping mechanism secures test coupons without additional tools, enabling rapid specimen loading on site and reducing the setup time that discourages frequent testing during active geomembrane installation.
• Single-Operator Field Use: Because the cordless drill is self-contained and the clamping mechanism requires no tools, the EXAMO 100 can be fully operated by one person – with one hand on the device and one operating the drill – making it practical for individual quality inspectors working across large installation areas.
• Specimen Capacity up to 3 mm Thickness: Accepts test coupons up to 25 mm wide and 3 mm thick with a maximum test length of 100 mm, covering the geomembrane thickness range commonly specified in civil containment, hydraulic, and environmental engineering applications.
• Compatibility with Leister Geomembrane Welding Equipment: Designed to complement the full range of Leister GEO automatic welding machines including the COMET, COMET 500, COMET 700, GEOSTAR G5, GEOSTAR G7, TWINNY T5, and TWINNY T7, as well as Leister extrusion welding machines including the WELDPLAST S4, WELDPLAST 605, and FUSION 3 – closing the quality assurance loop across the Leister geomembrane welding system.
• Integration with COUPON CUTTER 500: Test specimens are prepared using the Leister COUPON CUTTER 500, which punches uniform-dimension coupons from the geomembrane for consistent and comparable peel test results – eliminating the dimensional variability of hand-cut specimens that affects result validity.
• Compact and Site-Ready Construction: At 1.4 kg and 283 mm in length, the EXAMO 100 is dimensioned for easy one-hand carry and transport across site, supplied with a plastic carry box for protection during storage and mobilisation between test locations.

Geomembrane Weld Testing Applications in Civil and Environmental Engineering

• Landfill and Containment Liner Quality Assurance: Conducts destructive peel tests on HDPE and PE geomembrane weld seams in primary and secondary containment liner systems, verifying weld integrity at the point of installation before backfill or overburden placement makes remediation impractical.
• Reservoir and Canal Lining Weld Verification: Enables on-site peel testing across large-area hydraulic containment geomembrane installations where weld seam count is high and consistent quality verification across the full installation is a project handover requirement.
• Environmental Barrier and Gas Barrier Inspection: Supports the quality assurance programme for geomembrane gas and environmental barriers in civil construction, providing a site-portable testing method that does not require removal of specimens to an off-site testing facility.
• Aquaculture and Irrigation Project Commissioning: Provides civil engineers on aquaculture pond and irrigation reservoir projects with a practical weld verification tool that can be used during installation – identifying substandard seams before the liner is put into hydraulic service across project sites in Oman and the GCC.
• Routine Quality Control on Active Geomembrane Installation Sites: The cordless and lightweight format enables quality control personnel to increase peel test frequency during active installation without disrupting welding productivity – supporting a systematic quality assurance approach on large civil earthworks and infrastructure projects.
