FAQ's

If you have a soft area in a road, parking etc., 2” minus is by far the best product to tighten up the area. 2" minus is a ground stone that forms a tighter pack with gravel fines. The larger 2” particles together with the fines create a mesh that binds and will help bridge the soft area. The 2” minus is adequate to drive on temporarily; however, capping with a finer granular product such as Granular M is recommended. It is recommended to place 2” minus with a machine, i.e. skid steers etc., as the material is difficult to shovel.
If the area is exceptionally soft, placing a layer of geotextile down first will help bridge the material and keep the softer substrate material from coming up through into the granular layer. We recommend placing 2” minus over the geotextile. 4” minus is also a recommended product for this application, however we find the 2” minus does a comparable job and is easier to grade and work with. As well, 2” minus offers a better temporary driving surface over 4” minus.
2" is ground rock used as a base layer for projects. We do not manufacture 3” Minus and recommend 2” minus. We find that the 2” minus is much easier to work with and grade. Often the base layer will remain through a construction project without fine gravel on the surface, which offers a better driving surface for temporary traffic. Some contractors offer a 3” minus or call it a Granular B Type II. This material will perform the same, but is more difficult to grade and the driving surface is not as desirable as a 2” minus. Although we do manufacture 4” minus, we use 2” minus ourselves 99% of the time when constructing a base layer, and we recommend the same.
The answer is none. Technically, Granular B (Type II) is a manufactured product, such as crushed granite that passes through a 4” screen. We manufacture our Granular B Type II with 100% granite as a 2” minus product. Some contractors manufacture as a 3” minus product. The 3” minus will perform the same but is more difficult to grade and the driving surface is not as desirable as a 2” minus.
All of our crushed stone products are Granite and manufactured at our local quarries. Granite is a superior product to Limestone. Limestone will breakdown quicker over time, will create a slimy surface when wet and will track into a house. Granite products will not breakdown, go slimy or track as easily.
