Limestone Base

Limestone Base

Also referred to as Caliche, Road Base, Crushed Stone Base, or Flex Base. Limestone Base is a versatile crushed stone aggregate that can be used in applications ranging from landscaping and other home applications to large-scale road and highway construction. Limestone base is produced to be in 1.5 inches in size down to fines (small particles of rock) and comes in varying, naturally occurring colors such as gray, tan, and light brown. 


When compacted, the combination of limestone rock and fines interlocks to form a dense layer of stone with minimized voids between stones. As the fines settle into the voids and water evaporates from the compacted materials, the remaining minerals act like an adhesive, binding the gravel together. After just a few weeks, limestone base becomes a hardened, long-lasting material that will require minimal maintenance or repairs. 

Limestone base is an economical and aesthetically pleasing choice for driveways, roadways, parking lots, lay down yards, and much more.
