THINGS TO KNOW

SienaStone Smooth

SienaStone is an engineered large module (min 500 lbs/250 kg ea.) retaining wall system with incredible capacities for both gravity walls and reinforced walls. SienaStone is mostly used in commercial applications or in residential applications where higher and stronger structural walls must be constructed.

Applications – Structural retaining walls for large embankments.

Capacity – Gravity walls up to 13’ (4m). Geogrid reinforced walls up to 39 ft. (12m).

Recommended Base Stabilization – one layer of DriveGrid stabilization grid between subgrade and base material. Use under Standard Base or Permeable Base.

Standard Base – Min. 6” – 8” of ¾” Crusher Run gravel (any road base standard in accordance with ASTM-D2940) compacted to 98% Standard Proctor Density (SPD).

Alternative Permeable Base – Min. 6” – 8” of ¾“ clear open-graded stone compacted to achieve full particle lock-up and consolidation. (Clear open-graded does not compact but does consolidate slightly by rattling the particles together.)

Leveling – Install SienaStone directly on a compacted granular base. Install level end to end as well as front to back. Poured concrete leveling pads, reinforced with rebar, are also a great way to accomplish leveling, especially for larger installations. You must ensure that the concrete is poured and finished perfectly in order to achieve a good visual appearance.

Connection – features a tongue and groove connection. Use appropriate concrete adhesive for connection between units where the key has been removed or for corners. Always read adhesive manufacturers’ directions prior to gluing.

Handling – This is a mechanically placed wall system. Special clamps for lifting are available for use during project.

Coping - This wall requires the SienaStone specific coping. Coping attaches with tongue and groove connection. No adhesive required.

Technology advances, new product offerings, and equipment improvements have led to safer and faster step build projects. It’s important for design/build contractors to stay accountable on these updates and to regularly assess whether their current processes and tools are efficient.
3D Landscape Design: Is it time to add it to your toolbox?
A meticulously hand-rendered landscape design plan is incomparable to anything else. The ability to draw every detail, from the smallest plant to the largest water feature, is a skill that creates functional works of art that, up until recently, drew customers. Today, however, landscape design has joined the rest of the design world: technology is king. As competition in the landscape industry becomes fiercer, owners are looking for anything that can help set them apart. 3D design is a great opportunity to do just that.
