Backfill material becoming frozen in cold weather.
DIRECT BENEFITS Mechanical Padding:
Reduces damage to the pipeline coating and pipe from rocks and hard materials that may be situated in the spoil pile;
Ensures better and more consistent compaction during the backfill process which contributes to preserving the integrity of the pipeline by securing it in place;
Facilitates maximum ditch spoil replacement and soil compaction during the backfill process;
Eliminates soil contamination, what comes out of the ditch goes straight back in during the backfill process – the Green alternative; and
For underground electrical cable, mechanical padding reduces cable damage from rocks and hard material that may be in the spoil pile and facilitates even heat dispersal through consistent soil compaction.
BARGAIN PRICE INSURANCE
Mechanical padding is not just a specialty item for backfilling pipelines where there are known deposits of rock and hard material;
Mechanical padding is the optimal method of backfilling a pipeline ditch; and
Proper use of mechanical padding can virtually eliminate any risk of damage to the pipe coating or pipe during the backfill process.
Availability of backfill;
Cost of backfill;
Quality of backfill material;
Project specifications; and
Backfill is the final critical stage in the pipeline construction process after lowering in the pipe; and
If the pipeline is not properly backfilled, all of the earlier steps such as coating the pipe, welding the pipe, scanning the welds, coating the joints, etc. in order to assure the integrity and long-term viability of the pipeline are at risk.
