COPTHORNE®
Inspired by the rich color and timeworn beauty of European street pavers, Copthorne offers more delicate dimensions than Town Hall. These proportions make it possible to design curved walkways and borders using Copthorne, without the need for cutting. Cast using Reala™ Technology for an authentic surface appearance, and using Ultima™ Concrete Technology to deliver up to four times the strength of conventional poured concrete, Copthorne offers timeless beauty for driveways, walkways, patios, vertical feature accents and more.

Deep, rich colors and a multitude of unique Reala™ textures combine to deliver the timeless beauty of Unilock Elegance. From the timeworn look of European cobblestones, to the classic luxury of riven natural stone slabs, our Elegance collection offers styles you can’t get anywhere else and thanks to Ultima™ Concrete, the look you purchase is the look that will last, with up to 4x the strength of poured in place concrete and EasyClean™ integral stain resistance.
Unlike after-market sealers which merely coat the top, EasyClean goes beyond the surface and becomes integral to the product during manufacturing. The result is enhanced surface color and protection from stains.
Only Unilock has the technology to manufacture Ultima Concrete here in North America, resulting in pavers and walls with up to four times the strength of poured concrete. The look you purchase is the look that will last.
A multitude of natural stone surfaces, brick and historic cobblestones were cast to create Unilock products utilizing Reala technology. The result is a wide variety of authentic textures with consistent dimensions which are more cost efficient to install.
The color of jointing sand you choose can have an impact on the overall look and feel of your paver patio, driveway or pool deck. Experiment with different options here.
COPTHORNE®
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:
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.
Sealers
The Americans with Disabilities Act Accessibility Guidelines (ADAAG) provides measurable criteria to determine compliance, not individual product evaluation. Gaps, joints or openings, greater than ½” horizontal and ¼” vertical should be avoided as they can disrupt wheelchair maneuvering (United States Access Board – Guidelines and Standards).
