The soils engineer should <br /> monitor the excavation operation to ensure compliance with our <br /> �*:, <br /> recommendations . <br /> All fills required to bring the building pads to final grade <br /> should be placed as engineered fill. The subg rade of the slabs <br /> should be prepared to provide a moisture barrier . It is <br /> recommended that an impermeable membrane covered by at least 2 <br /> in-dh.ds.,.:, of moist concrete sand be placed beneath all interior <br /> s 'Ei s-on-grade. The impervious membrane should impede capillary' <br /> iii <br /> action while the moist concrete sand will aid in concrete curing <br /> and- finishing . <br /> Adjacent exterior finished grades should be sloped a minimum <br /> of---'one percent away from all interior slab areas to preclude <br /> Pn-di,.hgzof water adjacent to the structure. <br /> 20, <br /> 7Swimmin2 Pools : Any areas to receive swimming pools should <br /> b F-p epared , in general , as outlined in the "Spread Foundation" <br /> se.C.*i,,On- of this report.
