Pier & pad spacing will be determined by the manufactured hemes' written set-up instructions or any <br />local or state codes. , <br />4. The open cells between the ribbing on the upper side of thcpads may be f1l1ed with soil or sand after <br />installation to prevent any accumulation of stagnant water b. the pads, <br />5. A pocket penetrometer may be used to deterlr'~e the actual so11 bearing value, If soil-te!ting <br />equipment is not ~vailable, use an assumed soil value of 1000 lbs./ square foot. <br />6. All pad sizes shown are nominal dimensions and may vary up to liS". . <br />7. The maximum deflection in a sinale Jlad is 5/8" measured Itom the highest point to the lowest pamt <br />of the top face. (NOTE: Actual test results were less than S/8" ) <br />8. In frost areas, a 6" deep confined gravel base installed in well drained, non-frost susceptible soil is <br />recommended. <br />9. Pad loads arC the same when using single stack or double Htack blocks. <br />10. The maximum load at any intermediate soil value may be ".ietmnined as the average oftbe next <br />lower and next higher soil value given in the table below. <br />11. Any configuration (see reverse side) may be used to replace a home manufacturer's recommended <br />concrete or wood base pad. <br />12. If the home manufacturer shows soil densities greater funn 3000 lb. when using ADS pads, do not ex.ceed <br />3000 lb. soil pier spacings per set up manual. <br /> <br />Pad Size <br /> <br />Pad Area <br /> <br />1000 lb.
