compactor with a piece of carpet or rubber mat under the compactor to prevent the pavers from being scratched or damaged. After each pass of the compactor sweep in more jointing sand and compact again before sweeping off excess sand. (see Figure 10). Figure 10 For small areas, pavers can be compacted by using a hammer and a hardwood plank.

built into each mix design and you should be familiar with what constitutes good concrete: 1. Cement and water combine chemically to bond the sand and coarse aggregate together. Ground granulated blast furnace slag and flyash may also be used as cementing materials, but always in combination with cement.
