Final Soils Report March 5 ln2l
Probing and testing of the slab subgrade areas showed acceptable geotechnical conditions for
support of the proposed slab.
BASEMENT/GARAGE WALL SUBDRAIN
The subdrain for the basement/garage wall consisted of four inch diameter SDR 35 perforated
drain pipe (holes down), surrounded by one cubic foot per lineal foot of 3/4 inch rock wrapped in
filter cloth. The subdrain was placed in accordance with plans and geotechnical
recommendations. Proper outlets of the subdrain system are the responsibility of the contractor.
BASEMENT WALL BACKFILL
Backfill of the basement walls, as requested periodically by the contractor, was observed from
October 29, 2021 to November 2, 2021. The basement wall was backfilled with 3/4 inch gravel
to three feet from top of wall. A soil cap was placed above the gravels and separated by filter
fabric. Backfill soils were placed in thin lifts; moisture conditioned as needed and mechanically
compacted to a minimum of 90% relative compaction up to finish pad grade elevations.
Equipment used for compaction of fill soils consisted of mechanical hand compactors and a SVL
75. Earthwork was completed by Coast Concrete.

Hardscape subgrade areas around the residence were observed between December 13, 2022 and
March 2, 2023. Probing and testing of the requested hardscape subgrade areas indicated
acceptable geotechnical conditions for support of the proposed hardscape.
