SODDING DETAIL
SODDING SPECIFICATIONS
DESCRIPTION
Prepare soil, furnish and place limestone, fertilizer, sod and water, and other operations necessary for the
permanent establishment of vegetation from sod on yards, shoulders, slopes, ditches, or other areas. Adapt
operations to variations in weather and soil conditions so as to assure the successful establishment and growth
of grasses. Preserve the required line, grade and cross section of the area treated. The actual conditions
which occur during the construction of the project will determine the quantity of water used and mowing
required. The quantity of water or mowing may be increased, decreased or eliminated entirely at the direction
of the Engineer. Such variations in quantity will not be considered alterations in the details of construction or
a change in character of the work.
SODDING
(A) Handling and Storing Sod
Exercise extreme care during all operations of loading, transporting, unloading, storing, placing, tamping and
staking sod, to prevent breaking the sod sections and to prevent the sod from drying out. Any sod that is
torn, broken or too dry will be rejected. Torn or broken sod, if kept moist, may be used for filling
unavoidable small gaps in sod cover as permitted. Place sod on the designated areas within 48 hours after
being cut unless otherwise directed.
(B) Soil Preparation
Remove litter and other debris. Mow and satisfactorily dispose of weeds and other unacceptable growth on the
areas to be sodded. Bring the area to be sodded to a firm uniform surface at such elevation that the
surface of the complete sodding conforms to the finished grade and cross section as shown in the plans.
Scarify or otherwise loosen soil to a depth of not less than 5". Break clods and work the top 2" to 3" of
soils into an acceptable soil bed by using soils pulverizers, drags or harrows. Place limestone and fertilizer
before placing sod. The plan will state the kind and grade of fertilizer, and the rates of application of
limestone and fertilizer. Distribute the limestone and fertilizer uniformly over the area and thoroughly mix in
the top 5" of the soil by discing, harrowing or other approved methods. Prepare the area by harrowing,
draggin, raking or other approved methods to give a lawn type finish. Remove all trash, debris and stones
larger than 1 1 /2" in diameter or other obstructions that could interfere with the placing of the sod. Moisten
the finished surface with water before placing sod.
(C) Placing Sod
The plan will state the season limitations for sodding and the kind of sod to use. Sod handling and
placement will be continuous process of cutting, transporting and installing without appreciable delays. Install
sod within 48 hours after being cut and water immediately after installation. Place sod firmly and carefully by
hand within 24 hours after soil preparation is completed and accepted by the Engineer. Pack each piece of
sod tightly against the edge of adjacent pieces so that the fewest possible gaps will be left between the
pieces. Close unavoidable gaps with small pieces of sod. When placing sod on a slope, begin at either the
to or the toe of the slope. Place sod with the Ion edge horizontal and with staggered vertical joints. Turn
P P 9 9 99 1
the edge of the sod slightly into the ground at the top of the slope and place a layer of earth over it and
compact so as to divert the surface water over and onto the top of the sod. Stake sod in place by driving
stakes flush with the sod, on all slopes 2:1 or steeper, in drainage channels, on other areas shown in the
plans, and on any areas that are in such condition that there is danger of sod slipping. Perform staking
concurrently with sod placement and before tamping with sound wooden stakes which are approximately on inch
square or one inch in diamter and not less than 12" in length. Place enough stakes to prevent slipping or
displacement of the sod. Drive stakes perpendicular to the slope. Where backfill is necessary on cut slopes
to obtain a uniform sodding area, provide stakes of sufficient length to reach as [east 3" into the solid earth
underneath the backfill. On all areas, use metal staples in place of wooden stakes. The metal staples should
be 12" long, made of 11 guage new steel wire so as not to bend when pinned or driven through the sod.
Shorter staples may be used with the approval of the Engineer. Place, stake and staple the sod where
necessary, then tamp or roll carefully and firmly by acceptable means. If rolled, roller shall weigh 150 Ib/ft
of roller width. Take extreme care to prevent the installed sod from being torn or displaced. Do not place
sod when the atmospheric temperature is below 32'F. Do not use frozen sod or place on frozen soil.
(D) Watering Sod
Water carefully and thoroughly after sod has been placed and tamped. Perform watering as directed until final
acceptance. Application of water may be made by the use of hydraulic seeding equipment, farm type irrigation
equipment or by other acceptable means.
