Seeding or Broadcasting Natural Aggregates, Colored Glass,
Terrazzo Chips/Stone, Rock Salt, etc.
Into Wet Resin or Concrete
The possibilities are limited only by the imagination
or the whims of the client.

Often overlooked by resinous flooring and decking contractors, these aggregate and/or glass combo systems offer a whole new approach to a unique looking decorative surface for ramps, floors, and decks.
Decorative concrete contractors have seeded/broadcast onto fresh concrete for years. Specialty systems such as Lithocrete, have been developed around the seeding/broadcasting on fresh concrete.
A vast majority of broadcast chip sizes into concrete are #0 up to #3. Our experience is up to #4 chips size (~1/2" / ~12mm) but the machine may broadcast larger size especially with the SuperShute attachment.
(natural occurring beach aggregates)
A somewhat new wave in stone mix design is to add colored glass to the natural aggregates to accent the monochromatic bagged aggregate.
(Mix designs below and above consist mainly of #0 - #2 (~1/16" x 1/4" or ~ 2-8MM metric) terrazzo stone sizes, sometimes called 'terrazzo chips' in the US, and glass sizes.)

Some of these designs mimic a somewhat 'natural' (caused by illegal dumping) occurring beach glass and natural sand & small aggregate deposits.
Natural Occurring Aggregate Examples
The broadcast aggregate examples above and below, may be broadcast and topcoated to offer a great looking skid resistant, rustic looking surface. The stone can be topcoated, ground lightly to produce 'butte' profile rather than a 'mountain peak' topography, then topcoated after grinding, or even ground smooth.
(Keep in mind, the stone sizes in the pictures above and below are #0 - #2 US Terrazzo sizes (~1/16" - 1/4"), Metric 2 - 8MM (~1/16" - 1/4")
