Sources of the material can include either"pit run" or"crusher run." Crusher run material <br /> wiIl generally require sharp sand to be added to mixture (33% by volume} to ensure long term porosity. <br /> If there is difficuiry in finding Iocal sources to meet this sieve analysis, and alternative mixture can be <br /> created by mixing 2/3 crushed drainage rock (0.7�"dia) with 1/3 concrete or river sand. <br /> 2. Selected materials should be neaziy neutral in pH (range from 6.5 to 7.2) to provide adequate <br /> root zone develapment for turf. <br /> 3.
