HydroStraw® Original is a hydraulically applied mulch with a specially formulated composition of annually renewable straw fiber, natural fibers for fiber matrix entanglement, and a non toxic soil stabilizer.


The primary fiber shall be produced from annually renewable straw fiber; all fiber materials should be free from plastic materials or other non bio-degradable substances. Fiber shall be of such character that the fiber will disperse into a uniform slurry when mixed with water.. Fiber shall be colored green, and shall not stain concrete or other surfaces.

  • 60 lbs per 100 Gallons for hose work
  • 75 lbs per 100 gallons for tower work

Increased performance can be achieved by mixing infield a hydro-colloid tackifier such as guar per manufacturer’s recommended rates.  It is imperative that the mulch be applied at the specified rate: too wet of a mixture will cause the fibers to be buried into soil. Mulch Fiber shall be applied as a slurry solution by means of hydroseeding. Mulch Fiber shall be applied at the specified rate per the specifications in a uniform manner. Care shall be exercised to ensure that the mulch application is uniform and even throughout the seeded area; mulch shall not be bunched or clumped up on the site. Care shall also be taken as to not create a shadowing effect on the site, mulch applications shall be started on the windward side of the project.
