Gabion Retaining Wall Foundation

Gabion walls have a 35 void ratio.

Gabion retaining wall foundation.

Double width base gabion. Most gabion walls do not require concrete foundations. Gabion retaining walls can be designed and configured with a stepped front face or a smooth front face. Foundation testing small non engineered retaining walls are unlikely to require scala penetrometer foundation testing which accurately measures the subsoil bearing strength.

Foundation testing small non engineered retaining walls are unlikely to require scala penetrometer foundation testing which accurately measures the subsoil bearing strength. Most gabion retaining walls don t need concrete foundations. The extra width of the base gabion improves wall stability and reduces the bearing load on the subsoil spreading the load over a larger area allows gabion walls to be built on weaker subsoils without expensive foundations. Also the foundations are flexible and strong and can absorb the different founding conditions of poor clay or undrained soils.

Most gabion retaining walls don t need concrete foundations. When utilizing a gabion wall with a smooth front face the gabion wall should be placed on a 5 6 degree batter and is not recommended for walls above 18 high. The worst material for gabion walls to sit on is soft clay if the ground is likely to sink under baskets weight a gabion retaining wall may not be possible. Retaining wall design takes into account site conditions soil types and loads above and behind the retaining wall.

Gabion retaining walls in modern architecture gabion walls in modern architect designed homes gabion walls are an integral part of the design of the zeb pilot house. Larger gabion retaining wall solutions use thicker gabions at the base to spread the foundation load and improve resistance to overturning and sliding. Depending on the wall height a 50mm to 100mm layer of compacted 20mm road base crushed from either blue metal or basalt rock is all that is required for most gabion walls. Most gabion walls do not require concrete foundations.

The zeb pilot house in norway is a good example incorporating gabion stone cages in home design where they are used to build both interior and exterior walls.
