As a rail transload yard for construction aggregates, we source crushed limestone products, crushed granite products, and natural sand (Type C33), and deliver it via railroad to our Oklahoma City location for local client use.

KLAVER CONSTRUCTION COMPANY, INC.
Klaver Construction was founded in June of 1945 by Bill Klaver, Sr. The new company had very few assets but no shortage of desire and vision. Its first job was a curb and gutter project in Hugoton, Kansas, for Broce Construction. In the early years the company did almost exclusively curb and gutter and municipal concrete paving. During the mid-1960s Klaver Construction started doing box culvert work, primarily extending existing culverts, to allow for highway widening. On January 1, 1996, Klaver joined the Sherwood Companies.
Today, the majority of Klaver Construction Company, Inc.’s work involves concrete box culverts and reinforced concrete box bridges. The Company’s area of operation is all of Kansas and Oklahoma but has also included an occasional project in Arkansas and Texas. Klaver thrives on large, difficult structures that many of its peers shy away from. Klaver is known and respected by the state DOTs and prime contractors alike for the quality of their work and their integrity.
A small but significant niche for Klaver Construction is the sale and rental of portable concrete median barriers (Type F3). In the early 2000s, Klaver realized there would be a tremendous need for these barriers as the old style median barriers were being phased out in favor of the F3 barrier. The Company devised a forming system and started producing the barriers in conformity with the new specifications. Within several years, Klaver manufactured several hundred thousand feet of this new product. Although no longer producing the barriers, the Company has become very proficient at setting barriers, sometimes totaling tens of thousands of lineal feet per project for prime contractors on large interstate highway projects.
