We explain step-by-step how to check the air channel watertightness between the beads of a hot wedge weld with a pressure gauge and needle.

We explain step-by-step how to operate the hot wedge welder for HDPE geomembranes: preparation, calibration, dual-bead welding, and channel pressure testing.

We explain step-by-step how to operate the hot-air welder for geomembranes and plastic sheets: preparation, calibration, execution, and inspection of the seam.

We explain step-by-step how to operate the extrusion welder for HDPE geomembranes: joint preparation, preheating, bead application, and inspection.

We explain step-by-step how to assemble an electro-welded gabion: base preparation, panel assembly, filling with suitable stone, and tying between adjacent cages.

We explain how to assemble, tie together, and fill hexagonal wire mesh box gabions with stone: stone type, internal bracing wires, and lid closing for retaining walls, riverbanks, and slopes.

Here's how to use HDPE welding rod in an extrusion welder: compatibility check, joint cleaning, patch testing, and constant-speed application.

Here's how to install the Poly Lock to mechanically fix an HDPE geomembrane to a concrete structure: embedded in fresh pour or anchored to hardened wall, extrusion welding, and sealing.

We explain how to install nodular drainage sheeting on garden walls, planters, and green roofs: nodule orientation, cutting, fixing to the wall, overlaps, and top trim.

We show you how to fill, close, and stack geo-bags for temporary flood barriers and slope stabilization, using material available on site and manual handling.

Here's how to install the GCL step-by-step for waterproofing landfills, lagoons, and reservoirs: subgrade, perimeter anchor, overlaps with extra bentonite, and cover in less than 24 hours.

Here's how to install the drainage geocomposite behind a retaining wall: preparation, foot drain, unrolling against the wall, overlaps, and gradual backfilling.
