When your hardscape design demands the vintage look of European clay brick pavers, Copthorne steps up to the plate. The slightly narrower scale allows exceptional flexibility when it comes to winding walkways and radius borders, minimizing the number of cuts you have to make. The versatility of Copthorne is expanded more when used to accent walls and outdoor living features. Manufactured with Reala™ and Ultima™ Technologies, you can be confident that your customer will be pleased that you recommended Copthorne for their project.
The surface of each Copthorne paver is uniquely cast using Reala™ Technology to capture the feel of Europe’s oldest brick streets. Made with Ultima™ Concrete Technology, you not only get that bygone look and feel, but with the assurance that Copthorne can be used in the most demanding of applications.
Recommended Base Stabilization – one layer of DriveGrid™" stabilization grid between subgrade and base material. Recommended depth 8” to 10” below pavers for maximum stability and performance. 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).
Standard Bedding Course – 1” thick of coarse sand– in accordance with ASTM-D2940 screeded over base.
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.)
Alternative Permeable Bedding Course – 1” thick of 1/4” clear open-graded chip stone – (ASTM No. 8) screeded over base.
Special Note: Concrete Direct Overlay – In some areas of the country and in some applications pavers are very successfully placed directly over concrete. Concrete as a base is in itself quite strong, but it can affect the structural integrity of the paver particularly in vehicular applications, where the concrete below is sub-par. The following considerations must be taken into account to insure that the concrete below the surface is ideal:
Concrete integrity – concrete must be in good condition, and not crumbling
Drainage slope – concrete below must be sloped away from all buildings and structures
Drainage holes – In lowest areas of the concrete, drill 1” holes in concrete (on 12” centers) and fill holes with ¼” chip (ASTM No. 8)
Base drainage - the area below the concrete must not be subject to frost movement
Surface - surface must be totally smooth and flat equivalent to the desired finished surface
Waterproofing - may be required when installing pavers over concrete where there is a basement or cold cellar below. Install an impervious rubber membrane over the surface prior to installing any pavers over the surface.
Jointing Sand - Use an impervious polymeric sand when installing over concrete
Jointing Material and Joint Stabilization
All sands must meet ASTM C144 or C33 Specifications. For best appearance and optimal performance,, keep jointing materials approximately 1/8” below the chamfer (bevel edge) of the paver.
Good Option: Ordinary sharp jointing sand in accordance with ASTM C144 or C33. (Common name: Concrete Sand)
Best Option: Any polymeric sand or ordinary concrete sand stabilized by a water-based or solvent-based joint sand stabilizer sealer. Always follow manufacturer’s application specifications and requirements.
Handling – This product has no special handling requirements.
Edge Restraint - Always install an edge restraint around the perimeter of any paver installation not restrained by building structures. Spike-in edge restraints come in plastic and metal and work well for most applications. A concrete curb or a sub-surface concrete wedge can also be installed to retain the edge.
Paver Compaction - Always use a protective polymer pad on the bottom of your compactor when doing the final compaction of the pavers. An alternative is to use a rubber-roller compactor for the final compaction.
Cleaners – Any cleaner specifically designed for pavers may be used for color restoration or general cleaning. Follow manufacturer’s dilution rates and application procedures. Always test a small area to make sure the results are as expected.
Product may be sealed for aesthetic or cleanliness reasons but it is not required

Copthorne by Unilock, is an old style paver emulating the look of European streets and courtyards.
Why Unilock’s Products Are Great to Install
Jeff Hummel from Hummel's Landscape explains why he chooses Unilock products first, and why the quality of the product makes it easy when it comes time to install.
Unilock products and service – best in the industry
Leon Raber from Creative Hardscapes talks about the quality and innovation of the Unilock product, and the wide range of color tones available. He also explains how he is most impressed with the contractor service provided by Unilock, and how the support makes him feel like family.
Why Unilock products are top tier
Dave Caroselli from Shearer Patio & Landscape Services explains why being creative in the hardscape industry is something that he enjoys and why he feels that Unilock product is top tier in the industry. He also talks about how the UniLyft system has helped him efficiently complete a project with speed and precision.

Where to Buy
Unilock has an extensive network of dealers with deep knowledge of our products.
A major portion of the landscape construction business is selling the right products for the right projects. When it comes to pavers and retaining wall systems with higher square foot prices, however, some contractors shy away from pitching them for fear of scaring away the customer. Unilock products like EnduraColor Plus pavers, while costing more, are actually very sellable to homeowners when presented in the right way.
Whether you operate a large company with an extensive team or you run a three-person operation, UniLyft will benefit your business in two specific ways. It will significantly reduce the time required to complete projects, and your staff will be both safer and less physically exerted during the paver installation process.
It’s been a few thousand years since the first roads were built, but there’s still no shortage of opinions about the right way to build them. For one reason or another, materials that have been good enough to get the job done for years come under scrutiny and are summarily deemed to be no longer acceptable. When it comes to building walkways or patios with interlocking concrete pavers, there’s one material commonly used for bedding that’s fallen out of favor (although not with everyone) in a big way: stone dust.
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.
