Runway
Compaction grouting densifies soils under existing or planned runway embankments for settlement control, stabilizes active sinkholes, and mitigates sinkhole activity for planned runways. Injection systems improve subgrade conditions prior to new runway construction, or beneath existing runways to improve conditions before new overlays. Vibro replacement stone columns and compaction grouting mitigate liquefaction for new runway embankments and expansions. Dynamic compaction densifies soils for runway construction. Wick drains accelerate the consolidation of soft soils to reduce runway construction schedules. Hayward Baker’s work provides support for many of the roadways in the U.S.
