THINGS TO KNOW

CONCORD WALL™ SMOOTH

Applications – Design and build projects such as planters, steps, grill islands, pillars, seat walls and water features. Can be used for straight and curved installations (Radius 5’ is the tightest radius).

Capacity – Gravity walls up to 24” (1m). Geogrid reinforced walls can be built higher with engineering from a professional engineer.

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 – Leveling retaining wall blocks directly on top of gravel is tedious and generally does not yield the best results. U-Grip Base units or universal base pads are recommended under all Unilock walls for improved accuracy and speedier installation.  Additional benefits include long term structural integrity and an overall better appearance.  Poured concrete leveling pads, reinforced with rebar, are also a great way to accomplish leveling, particularly 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 between layers. 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 – Avoid bumping units against each other to prevent chipping.

Coping - This wall requires coping. Choose a manufactured coping such as Pisa Coping, Universal Coping or any of our natural stone coping options. Install with tight joints or 3/16” gap between units and amend with an exterior latex caulking. Cutting may be required; a diamond blade saw is required to cut coping properly. Glue all coping using a specially formulated concrete adhesive that is strong and will not break down over time. Always read adhesive manufacturers’ directions prior to gluing.

Classic
Design trends rise and fall, but for something to be considered classic it needs to be both timeless and elegant. No two words could better describe the Unilock Classic paver. Available in a wide variety of shapes and styles, Classic pavers are made using a proven manufacturing process—blending cement, colors, and stone aggregates into a single batch and distributing the mix throughout the finished paver. This ensures a uniform look that is strong but capable of being formed into the wide variety of styles Classic is known for.

Pool Installers – Expand Your Business with Hardscape
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.
