2.01 Minimum and Maximum Cover Heights for HDPE

The maximum burial depth is highly influenc ed by the type of backfill and level of compaction around the pipe. General maximum cover limits for ADS N-12, N-12 ST, N-12 WT pipe, (ASTM F2306 and AASTHO M252/M294 Type S pipes) are shown in Table 3 for a variety of backfill conditions.

The encasement holds the flexible pipe in its circular shape and supports most of the external load. The pipe is an impermeable liner in a concrete conduit. The flexible pipe is designed for internal pressure by classical methods.
