Earth Friendly Segmental Retaining Wall Systems

Northern California with its hilly topography and sufficient annual winter precipitation and dryer summers poses as a perfect hot spot for soil erosion and gravity shifting, ultimately making retaining walls necessary for architectural development (residential and commercial).

While most retaining walls heavily dependent of solid fills and mortar work extremely well in many regions, the Segmental Retaining Wall offers many benefits, both structurally and environmentally.

How Segmental Retaining Walls Work
CastleLite Block’s SRWs replace traditional retaining wall hardscapes with landscape that doesn’t sacrifice any of the structural capacity necessary to adequately stabilize unruly slopes. Urban development density has seen a sharp increase over the past decade. With more and more San Francisco residents flocking to more affordable suburban living in the San Jose area, the population has been increasingly exploding. With this increase in population has also increased urban sprawl, drastically adding to the valley’s overall groundwater pollution. Needless to say, the need for smart-engineered, eco-friendly retaining walls has become a necessity.

The SRW Blueprint
Conventional segmented retaining walls (SRWs) are modular concrete hardscapes offering structural solutions at the expense of environmental and aesthetic considerations. CastleLite Block, however, offers a range of more eco-friendly engineered SRWs solutions providing the same solid engineering, but with an emphasis on restoring environmental and aesthetic benefits. This includes:

  • Local production
  • Lower carbon footprint
  • Nutrient uptake
  • Heat island mitigation
  • Habitat creation


Why Choose Eco Friendly Engineered SRWs?
CastleLite Block’s eco-conscious Segmental Retaining Walls are engineered with the exact same structural soundness and reinforcement techniques as all other solid hardscapes and other SRWs. The difference between other hardscapes, however, is that our SRWs offer modules that provide a structurally sound facing to the reinforcement zone behind the wall face.

The reinforcement zone is engineered by a myriad of factors determined by the slopes above and below the wall. These factors include:

  • Soil conditions
  • Site hydrology
  • Typography
  • Leeching
  • Ground Porosity

These factors drive the calculations used for the proper reinforcement design. These same conventional engineering methodologies are the same methodologies used for any other conventional SRW and traditional retaining wall systems.  Thus, the structural integrity of CastleLite Block’s SRWs are completely sound.
