They are very similar to hearting and could be ...
Sand is the primary material used in the construction of any building. There are many types of sand used in construction that provides strength and other properties to construction materials making the building strong and rigid. Construction Sands and Gravel are extensively used to prepare concrete that goes into the construction of buildings.

use. Several bridge designs are included in Appendix 1. When the span is less than 10 feet and the bridge is not subject to flooding, a simple puncheon type bridge may suffice. Crossings over 10 feet wide can often be crossed with a single-span bridge. These normally require the construction of cribs or fills on each bank, two to
Apr 29, 2009 The type of stone used, how it is finished and laid, and the width, color and profile of the mortar joints all contribute to the appearance of a stone wall or above ground foundation. Stone commonly used for walls and foundations include granite, lime- stone, sandstone and marble. Each comes in a variety of colors

The specific gravity of good building stone is between 2.4 and 2.8. Porosity And Absorption. The porosity of building stones depends upon the mineral constituent and structural formation of the parent rock. If stones used in building construction are porous, then rainwater can easily enter into the pore spaces and cause damage to the stones.
