In seismically active areas, improvement of loose, granular soils below the water table provides protection from damage related to liquefaction and lateral spread.

Liquefiable soil does not mean a site has to be abandoned, or that heavy foundations are required. Keller can apply several cost-effective techniques to mitigate liquefaction. 

Liquefaction is a common problem in earthquake-prone areas where soils lose strength due to the ground motion and behave like a viscous liquid, damaging overlying structures.
