quarries and pits mine a wide variety of minerals that are processed into
final end-use products or delivered in virgin form to the construction
industry and other specialty markets (ie. golf course sand and masonry
products). Typical Schmidt Aggregate products supplied and their end uses
Crushed Stone or Rock
Schmidt Aggregate’s Mencenberg
and Menzer Quarry’s
produce crushed stone from natural deposits of rhyolite and granite. Production
of these products requires blasting and excavating the broken stone from
these mines, followed by progressive stages of crushing, screening and
The company’s aggregate products range in size from riprap, where
each stone may weigh several tons, to manufactured sand for use in concrete
and asphalt applications.
Schmidt produces various size rocks and gradations of crushed stone for
specifications established by governmental agencies and our commercial
customers. Crushed stone is used in highway construction, railroads, airports,
water and sewage systems, and in residential and industrial building.
Rhyolite from the Mencenberg Quarry and Split
Stone Quarry is a rare and beautiful stone, which was formed by volcanic
activity. The word Rhyolite comes from the Greek word for stream (rhyax
+ the suffix lite). Rhyolite was named streaming rock because of its beautiful
flow bands created by thin layers of ash fall tuff that
originated from volcanic eruptions 35 million years ago in central Colorado
and deposited in the Castle Rock area.
This decorative stone is used in landscaping, retaining walls, and as
decorative face veneer for buildings and bridges.

Sand and Gravel
Schmidt Aggregate’s Fountain,
and Coal Creek
pits harvest sand and gravel from both glacial and alluvial deposits.
Surface mined natural sand and gravel resources produce specification
aggregate blends for asphalt, concrete, road base, and utility operations,
as well as masonry and golf course sands.
The company’s diligent quality control and flexible processing plants
ensure that a wide variety of products are available to mt the requirements
of federal, state and local agencies, as well as commercial and residential
Specialty sands are also produced for masonry and golf course applications.
The company’s golf
course sands are very fine grained and white, making them an ideal
product for sand traps and bunkers.
Asphalt is the most widely recycled product in the world.
Schmidt has been an environmentally responsible leader in recycling asphalt,
also known as RAP. Recycling asphalt helps preserve our valuable natural
resources, as asphalt contains significant amounts of petroleum products.
RAP is used by the Asphalt Division to supplement the manufacturing of
new asphalt, and can also be used as a crushed aggregate for road shoulders
Recycled asphalt is available to outside contractors from Schmidt’s
Colorado Springs and Castle Rock Distribution Depots.
