1 - TRENCH FLOOR PREPARATIONEnsure that the trench floor is smooth and firm, and within the design trench floor level limits of 80 mm minimum to 150 mm maximumbelow the bottom of the pipe, before placing any of the bedding.o lf the trench floor is in firm natural soil and an excavator is being used, it will normally be sufficient to trim it smooth with the excavator bucket.. lf the trench floor is in rock, backfill between peaks over 30 mm high with sand compacted to 100% of SMDD* before placing any bedding.. lf the trench floor has been over-excavated below design trench floor level, backfill with sand compacted to 100% of SMDD* to bring it back

up to design trench floor level before placing any bedding.o Remove loose soil or rock rubble from the floor of the trench.o lf the trench floor wholly or partially consists of: verv soft clay. loose sand. old or non-enqineered fill. or refuse, OR has isolated outcrops of

rock in it, OR has been disturbed by groundwater inflow, seek specialist geotechnical advice.

2 - BEDDING PLACEMENTDo not compact the bedding - simply rake or screed to grade. Dig out pockets to clear the pipe sockets.Avoid walking down the centre of the bedding during placing or after it has been placed.

3 - PIPE INSTALLATIONPlace the pipe firmly on the bedding, home it, and check that it is in contact with the bedding uniformly along its barrel.o For small diameter pipes, lift the end of the pipe and inspect the contact with the bedding visually. For larger or heavier pipes, check the

contact with the bedding by attempting to pass a hand under the pipe.¡ lf it is found that the pipe barrel does not have uniform contact with the bedding, pack in additional embedment sand.

Place a layer of embedment sand either side of the pipeup to half height of the pipe (DN 100 and 150 pipes) or100 mm loose thickness (DN 200 and 250 pipes).

Gompact by "walking in" using the toe of the boot topush the sand under the curve of the pipe. Ensure thatthe "footprints" are overlapping, and repeat until thesand takes no more compaction.

P|ace the remainder of the side support and the first 150 mm, loosethickness, of the overlay sand.

Gompact using an approved mechanical tamper with a plate notexceeding 150 mm wide. Keep the tamper close to the trench walland avoid any compaction directly over the pipe. Completesufficient passes to ensure no visible additional compaction on thelast pass.

Place a 100 mm thick (loose) layer of embedment sandeither side of the pipe.

Compact by "walking in" using the toe of the boot topush the sand under the curve ofthe pipe. Ensure thatthe "footprints" are overlapping, and repeat untilthesand takes no more compaction.

Place additional embedment sand up to half height of the pipe.

Gompact first by walking down each side of the trench withoverlapping footprints.

Compact next using an approved mechanical or hand tamper witha plate not exceeding 75 mm wide. Do not compact within 50 mm ofthe pipe. Complete sufficient passes to ensure no visible additionalcompaction on the last pass.

Place the remainder of the side support andthe first 150 mm, loose thickness, of theoverlay sand.

Compact using an approved mechanicaltamper with a plate not exceeding 150 mmwide. Keep the tamper close to the trench walland avoid any compaction directly over thepipe. Complete sufficient passes to ensure novisible additional compaction on the last oass.

Place the remainder of the overlay sand.

Gompact using a vibrating plate over the fullwidth of the trench to give not less than 100%of SMDD* as tested in the top 150 mm.
