Retaining wall fill photo gallery construction of bridge abutment fills over compressible soils can result in substantial settlements as a result of the grade increase.
Preloading and or surcharging the soil is commonly used to alleviate this concern.
The blocks are made from cement and lightweight aggregate materials.
