Sonomastone plays in the same arena as our other machine-placed walls but the false joints in each unit give the appearance of small hand-placed block. Couple that with our “triple unit placing clamp”, which we will loan you, and your installation will happen at lightning speed. Sonomastone, is a made-to-order product which requires a minimum order quantity. Speak to your local Unilock Territory Manager for more information about engineering and how to order.

THINGS TO KNOW

Sonomastone

A machine-installed wall with the look of hand-placed units. The combination of unit-size, design and a patent-pending installation clamp gives you unrivaled installation productivity, making SonomaStone one of the most efficient heavy-duty retaining wall systems available today.

Applications – Structural retaining walls for large embankments.

Capacity – Gravity walls up to 13’ (4m). Geogrid reinforced walls up to 39 ft. (12m). Refer to site engineer’s specifications for exact installation requirements.

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 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 SonomaStone specific coping. Coping attaches with tongue and groove connection. No adhesive required.

Like most pool construction companies, you’re always looking to increase your bottom line. Maybe you’ve considered hardscape installation in the past. Maybe you’ve even tried it, only to suffer losses and issues.
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.
