Sand types available
Preferred:
(If the goal is an "OIympic quality arena," then this is the only sand advisable/available.)
Makeup: Pure Silica Sand - Si02 (99.4% purity)
Durability: Long-lasting, due to non-porosity + adamant nature.
Customization: Available in custom blends of particulate sizes (ideal for different applications)
Sand cost: Slightly lower than Ravensdale, higher than CADMAN "bunker sand"
Delivery: Will be shipped via railcar to Monroe, to job site via local haulers
Less durable:
Product: Ravensdale
Makeup: Aggregate - largely consisting of Silica Sio2 (app. 70-90%, according to various authorities)
Durability: Eventually all non-silica components will decay into dust.
Will exceed lifespan of "bunker sand" below, with degradation commencing upon installation.
Eventually will degrade into:
70% to 90% Silica Sand
30% to 10% pulverized/decomposed stone dust
Customization: No
Sand Cost: Highest cost (more than Lane Mountain / ton, FOB sand pit)
Final cost would be comparable to Lane Mountain Silica.
Delivery: Must be shipped via truck from Ravensdale, Washington to job site overland.
Not advised:
Product: CADMAN "bunker sand"
Makeup: Aggregate - largely consisting of decomposed granite and shale, with some Silica
Durability: Non-Silica components will decompose into dust
(lifespan dependent upon traffic/use, freeze/thaw cycles, amount of watering, etc.)
Customization: No
Sand cost: Much more reasonable per unit
NOTE: Although initially less expensive, will require frequent replacement as the non-silica components decay.
Delivery: Locally Available - four (4) miles south of Monroe
(other sands are available, although we do not expect them to provide desired performance or durability)
