Slurry Clause Samples
The 'Slurry' clause defines the composition, quality, and handling requirements for slurry materials used in a project or contract. It typically specifies the acceptable mixture ratios, permitted additives, and standards for storage and transportation to ensure the slurry meets performance criteria. By clearly outlining these parameters, the clause helps prevent disputes over material quality and ensures that all parties adhere to agreed-upon specifications, thereby maintaining project integrity and safety.
Slurry. Use mineral or polymer slurry on this project to maintain the stability of the excavations. Manufacture mineral slurry from processed, high-sodium bentonite clays. Use polymer slurry that conforms to the manufacturer’s recommendations, that is site specific, and has been used successfully on a minimum of ten projects of similar size and scope. Adjust the percentage and specific gravity of the slurry used so that the stability of the excavation is maintained, and to allow for proper placement of the concrete. When using mineral slurry, adhere to the following requirements:
Slurry i. Seed as specified at a rate of 350 lbs./acre.
ii. Mulch: virgin wood fiber type applied at a rate of 1200 lbs./acre.
iii. Tackifier: Guar type or approved equal applied at a rate of 40 lbs./acre.
iv. Fertilizer: 19-19-19 granular applied at a rate of 500 lbs./acre.
v. Lime: Flowable liquid lime at a rate of 5 gallons per acre.
vi. Dye: Slurry must be green with dye added if not included with the mulch.
vii. Application rate: 3000 gallons per acre. Agitation must be maintained throughout mixing and application.
viii. Slurry shall be applied within 8 hours of the start of mixing.
ix. In lieu of hydro-seeding, seed may be drilled or an alternate method may be used. If an alternate method is used, seeding will have to be run in two directions. The second direction being at right angles to the first direction. Requests for using alternate methods shall be approved by the Project Officer prior to application of seed.
x. Sow seed at the rate of 5 to 8 lb/1000 sq. ft.
xi. Rake seed lightly into top 1/8 inch of topsoil, roll lightly, and water with fine spray.
xii. Protect seeded areas with slopes not exceeding 6:1 by spreading straw mulch. Spread uniformly at a minimum rate of 2 tons/acre to form a continuous blanket 1-1/2 inches in loose depth over seeded areas. Spread by hand, blower, or other suitable equipment.
xiii. Areas indicated on plan or exceeding 6:1 slope shall be protected with erosion control fabric, jute mat, or similar slope protection, installed according to manufacturer’s written instruction, and/or as approved by the Project Officer.
