In modern construction projects, EPDM is one of the most popular materials. Since its invention, it has developed large popularity due to its temperature and weather resistant property, low price and durability.

  1. Splice tape is the primary and effective way of seaming EPDM. Applying the splice tape to seam EPDM reduces the assembling time almost three times. The time required to seam a tape is reduced to five man-minutes from twenty seven man-minutes after applying this splice tape.
  2. The next one is a seam roller. The seam roller present has 6 inch long seam tape and ergonomic handle. These two parts reduced the requirement of applying hand in putting a seam tape. A worker can apply a seam tape using this roller in a standing position. The joint impact of both the seam tape and seam roller offers a seam that was as fast as heat welding applications.

The roofing industry and the EPDM system is constantly updated, and the new flashing and seaming instruments introduce great advancements in installation speed and quality. Among the best companies offering these modern seaming techniques, LiteEarth is topmost one, whose products are now globally accepted for their quality and service.

LiteEarth utilizes EPDM – a high performance thermoset geomembrane – as the liner. As a thermoset, EPDM is seamed using an industrial grade butyl adhesive splice. Unlike the fusion welding of thermoplastics, the splicing method is more efficient and performed without the need for generators and welding equipment while providing much higher shear force resistance. The panel to panel seaming procedure is very simple and has been used for years in many industries.

EPDM LiteEarth seaming process:
Two edges – one along the side of a panel and the other at the end – are manufactured with approximately one foot of the material without the grass. A thin coat of primer is applied to the top surface of one panel with the geotextile and the bottom surface of another panel with the geomembrane. A 7” wide butyl adhesive strip is placed between the primed surfaes which are then joined under slight pressure. This procedure achieves a strong and durable seam that is impermeable to both water and air.

LiteEarth seaming achieved good test results for peel strength, peel locus of failure, shear strength and shear locus of failure.

LiteEarth EPDM seaming technology advantages:

  • No welding, no stitching, no sand infill
  • Strong peel, shear and temperature performance
  • Features rapid flash-off and curing cycle
  • Used in thousands of applications for more than 25 years
