Harding County, NM Gravel and Landscape Rock Delivery
New Mexico Rock Supply brings gravel, stone and aggregate delivery in Harding County, NM to Roy, Mosquero, Mills and the surrounding ranch country. Base course is the material to start with.
It is what New Mexico calls road base, and it is the compacted layer that carries a drive, a parking pad or a slab.
Ground here is sandy and loamy over the Ogallala, with a cemented caliche caprock under much of the Llano Estacado. That caprock sits close to the surface in places, so the material you put down has to handle water that cannot drain away.
Ground Conditions Across Harding County
Spring through late fall is the working season. Winter wind and frozen ground stop compaction, and spring is the windiest and dustiest stretch of the year.
Time a delivery for ground that is dry and workable.
Wind erosion comes first across the Eastern High Plains, Llano Estacado and Canadian breaks. Open plains, dry springs and loose sand move soil, and storm runoff then cuts the caprock escarpment and the breaks.
Caliche caprock under shallow soil holds water near the surface. Low ground ponds after every heavy storm, so plan a drainage layer before you surface anything.
Repeated freeze and thaw works gravel drives loose every spring on the northern plains. Frost depth is commonly 18 to 24 inches around Clayton, Des Moines and Tucumcari, and less on the southern Llano around Portales and Clovis.
The county building official sets footing depth.
Materials Delivered in Harding County
Base course is the state base material.
Section 303 allows crushed stone, crushed or screened gravel, caliche, sand and recycled asphalt or concrete pavement. It sets two gradation bands, Type I and Type II, both passing a 1 inch sieve.
City specifications follow the same definition.
Order Base Course for driveways, parking pads, and slab and shed bases. The Type I and Type II bands describe how the material is specified in New Mexico, nothing more.
Stone screenings bed pavers and flagstone and fill joints, though crusher fines are the more common choice for that work in New Mexico. 3/8" Crushed Stone works as fine drainage, pipe bedding and a topping course over compacted base course.
Large River Rock builds dry creek beds and drainage swales. Fill Dirt raises grade and backfills before a base course lift goes down.
Mason Sand handles block, brick and adobe work, stucco coats and paver joints.
Choosing the Right Material
Quay County and Union County sit on the same ground as Harding County: sandy and loamy plains over the Ogallala, cemented caliche caprock, blow sand, and stony basalt and shale in the Canadian River breaks. The base and drainage choice is the same there.
San Miguel County spans more than one zone, reaching into the Sangre de Cristo, Jemez and the northern high country as well as the eastern plains. Where that high country begins, ground and drainage differ from the plains.
On plains ground, base course is the compacted layer for drives and pads. Where water stands over caprock, add drain rock or 3/4 crushed rock for a drainage bed.
On a slope or an arroyo bank, rip rap armors the edge against flash flow.
For a walkable surface, crusher fines pack firm and take color. Natural Pea Gravel and river rock suit beds and borders.
Topsoil and garden soil go over caliche, not through it.
