The Pro-Seam is designed, engineered and built by DEMTECH with two things in mind... The highest seaming production possible with a portable low cost welder and the most user friendly operation. We succeeded with flying colors.
The Pro-Wedge Model VM-20
The low cost, lightweight wedge welder that does it all! It is the top choice of installers worldwide for welding everything from thin PVC to geotextiles to thick HDPE geomembranes and everything in-between.
The Pro-Wedge Model VM-20FK
The Model VM-20FK has all the great features of our flagship Pro-Wedge with the addition of a removable in-house fabrication attachment. Great for high production seaming of flexible geomembranes on a concrete floor or in a track system.
The Pro-Wedge Model XL
The PRO-Wedge XL, Model 500-0100XL Wedge Welder, manufactured by DEMTECH Services, Inc., is the new standard of the industry wedge welder for production welding of thicker HDPE geomembrane seams. Drawing from many years of experience in the plastic welding industry, we've designed features and functions into its design to satisfy the needs of the most demanding welding technicians on the most demanding job sites.
