Banking excavated earth in layers not exceeding 20 cm. in depth, breaking clods, watering, rolling each layer with ½ tonne roller, or wooden or steel rammers, and rolling every 3rd and top-most layer with power roller of minimum 8 tonnes and dressing up, in embankments for roads, flood banks, marginal banks, and guide banks etc., lead upto 50 m and lift upto 1.5 m.

Note:(Refer CPWD specification clause 2.10.5)If the banking or filling is not consolidated to optimim moisture content the quantity of filling work out after actual measurement should be deducted by 10% to arrive at the net payable quantity. The measurement of excavation as prescribed in this item especially for consolidation, is not for consolidation with optimum moisture content.Hence the deduction of 10% quantity from the actual measured and calculated quantity to arrive a correct quantity for payment is mandatory.
