Light Weight Backfill Material For Retaining Wall
Geofoam is a lightweight fill in compliance with astm d6817 that gives you control over your geotechnical project.
Light weight backfill material for retaining wall. Wet cast densities range from 20pcf to 120pcf reaching strengths of 20 psi to 3 000 psi. The pervious concrete can be used in place of traditional foam fills methods as well as retaining wall fill. From design and timelines to materials and costs and ultimately control over your results. 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.
Retaining walls were also designed using conventional sand as the backfill material for comparison purposes. When comparing the overall cost for the retaining wall using shredded tires with the retaining wall using sand a substantial cost saving was realised by the use of shredded tires. For example when considering what to use for retaining wall support terefil provides the perfect retaining wall backfill. However this requires additional cost and time to implement.
The stability of the wall system is derived from the interaction between the backfill and soil reinforcements involving friction and tension. Strength at 1 strain the material remains in the elastic range and will not be susceptible to creep or experience plastic yield. By definition a retaining wall is a structure that is used for supporting the soil mass laterally so that the soil on different sides of the wall is retained at. Eps lightweight backfill and landscaping applications.
Lightweight flowable fill. Low density cellular concrete ldcc is a lightweight fill material primarily used in geotechnical applications ldcc is made by the injection or blending of pre formed stable foam into cement based slurry. Retaining buried wall backfill eps geofoam applications technical data by epsia 2012. Foam control geofoam is engineered to give you the greatest possible control for your project application.
Preloading and or surcharging the soil is commonly used to alleviate this concern. When you have built your retaining wall then you will need to add some backfill to the hole in order to shore up the wall and prevent any type of collapse of the underlying structure when you are ready to add your backfill to the hole you should make sure that you have enough suitable material to install in the hole and also take care that you avoid problems such as collapse of the.
