RD-6® Resistance to Soil Stress
Soil stress usually comes from backfill pressure as it settles around a pipeline. Typical result is a “bag and sag” at the 4 and 8 o’clock positions.
RD-6® has a Very High Resistance to Soil Stress
RD-6® has Very High Resistance to Soil Stress
The RD-6® soil stress advantage comes from its backing. The RD-6® backing is a high strength, low elongation polypropylene geotextile mesh. The RD-6® backing helps with soil stress three ways:
A. Higher Tensile Strength
Starts out stronger than HDPE shrink sleeves and tapes.
B. Less Stretchable:
A critical difference. 1/20th as stretchable as shrink sleeves or tapes.
C. More Resistant from Weakening from High Heat:
If your pipeline operates above ambient, polymers relax (begin to stretch) as you heat them. Polypropylene (used in RD-6®) has 75% higher resistance to this weakening than polyethylenes.
