Protecting underground pipes from potential damage due to soil stresses and backfill operations.

• Fabricated from resilient, closed-cell, chemically stable and inert polyethylene foam (Ethafoam).

• Multiple density construction with an inner core cushion, designed to yield then recover following expansion occurrence.

• Lightweight and flexible at low temperatures for easy installation.

• Protects pipe coatings from scrape, dent and puncture damage caused by contact with unfavourable backfill and environmental conditions.

• Resists severe degradation caused by exposure to hydrocarbons, bitumen, crude oil and liquid natural gas.

• Resistant to a wide variety of chemicals and common organic and polymeric soil contaminants.

• TEBS can be customized to each customer’s specifications.

• Resistant to insects, vermin and mould, and will biodegrade or crack.

• Performs consistently over a wide range of temperatures, resists cracking during cold weather installations.
