Concrete crib walls are gravity retaining walls which are constructed from precast concrete pillars which interlock to create a framework for drainage rock filling. Earth backfill and free-draining material remove hydrostatic pressure buildup better than many other popular retaining wall construction methods. Crib walls are affordable and can be quickly constructed almost anywhere.
The open web construction design featured in crib wall construction creates efficient drainage pores for removal of moisture from your soil and terrain. Koalas require minimal maintenance and can be planted with indigenous plants, and local wall garden varieties. Crib walls are flexible and can be built on slopes, hills, and around corners.
