2. Allow planting area soil surtace to dry out for one (1) day only prior to the hydroseeding
appication. Care must be taken not to allow the soil surtace to be super-saturated with
water prior to the hydroseeding installation. At the same time the soil surface should not
be bone dry. There should be some residual moisture within the first 114 inch of the soil
surface.
3. Hydromulching Application and Planting Schedule: the hydromulching shall be
applied in the lorrn of a slurry consisting of organic soil amendments, commercial fertilizer,
and other chemicals called for. When hydraulically sprayed onto the soil, the mulch shall
not form a blotter•like material. The spray operation must be so directed that the slurry
spray will also penetrate the soil surface so as to drill and mix the slurry components into
the soil, thus ensuring maximum impregnation and coverage.
4. Preparation of Hydroseeding Mixture: The slurry shall be prepared at the site and its
components shall be mixed to supply the rates of application as per section 2.11.
Application: The operator shall spray the area with a uniform visible coat using the dark color of the
cellulose fiber or organic amendment as a visual guide. The sluny shall be applied in a downward
drilling motion via a fan stream nozzle.
Time Limit: The hydroroolching slurry components are not to be lett in the hydromulch machine
for more than two (2) hours. tt slurry components are lett for more than two (2) hours in the
machine, the Contractor shall add 50% more of the originally specified seed mix to any slurry mix
which has not been applied within the two (2) hours atter mixing. The Contractor shall add 75%
more Of the original seed mix to any slurry mixture which has not been applied eight (8) hours after
mixing. Any mixture not applied atter eight (8) hours shall be rejected and disposed ot off-site at
Contractor's expense.
