Two inches of sand may be placed over the membrane for protection during construction and to aid in curing of the concrete. Site Drainage Groundwater was encountered in our test pits at depths ranging from eight to nine feet. Ha+�ever, it has been our experience that groundwater levels change significantly due to changes in rainfall amounts, sur£ace drainage or other factors. The excavation and site shoul.d be graded so that surface water is directed off the site. Water should not be allowed to stand in �ny area where buildings, slabs, or pavements are to be constructed. During construction, loose surfaces should be aealed at night by aompacting the surface soils to reduce the infiltration of rain into the soils. Final site grades shoul.d a�low for drainage away from the building foundations. We suggest that the ground be sloped 3 percent for a distance of at least ten feet away from the buildii�as except in areas that are to be paved. Pavement Areas All parking and re•idway areas may be supported on native soils or existing fills provided these soils can be canpacted to 95 percent density and are stable at the time of constr.uction. Structural fill and/or fabric may be needed to stabilize aoft, wet or unatable areas. In most instances twelve (12) inches of granular fill will etabi2ize the subgrade except for very soft areas where additional fill could be reguir�d. The upper twelve (12) inches of pavement subgrade ahould be compacted to at least 95 percent of the maximum density. Below this level a comgac�tive effort of 90 percent would be adequate. The pavement section for lightly loaded traffic and parking areas should consist of two inches of asphalt concrete (AC) over four inches of crushed rock base (CRB) or three inchea of asphalt treated base (ATB). Heavier loaded areas would require thiaker sections. We will *�e pleased to assist you in developing appropriate pivement sectzons or apecificationa for heavy traffic zones, if needed. Site Preparation and General Earthwork The building and pavement areas should 1� of all trees, surface vegetation, all organi.c de2et�rious material.
