Sand quality is recommended to be at least as coarse as the native sand (NRC, 1995a). Beach nourishment replenishes sand lost to erosion and protects the adjacent upland from storm wave impacts. The beach can be "engineered" so that its dimensions, both cross-section and shore planform, will provide a level of protection for known or predicted storm events (NRC, 1995a).

The replacement of sand by up to 40% of incinerator ash exhibits higher compressive strength than regular cement mortars (Al-Rawas et al., 2005). Some desert sand can be used if mixed with other material (Cisse et al., 2012; Zhang et al., 2006). There are alternatives for building houses, including wood, straw and recycled material.
Wood, in the strict sense, is yielded by trees, which increase in diameter by the formation, between the existing wood and the inner bark, of new woody layers which envelop the entire stem, living branches, and roots.This process is known as secondary growth; it is the result of cell division in the vascular cambium, a lateral meristem, and subsequent expansion of the new cells.
