THINGS TO KNOW

Tribeca Cobble

The sparkling granite, quartz and feldspar crystals embedded into the surface of Tribeca Cobble give it the look of real granite cobble setts that are used in many hardscapes today. With our proprietary EnduraColor technology, these non-fading minerals will provide endless performance with a lifetime of beauty and surface resilience.

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:

  1. Concrete integrity – concrete must be in good condition, and not crumbling
  2. Drainage slope – concrete below must be sloped away from all buildings and structures
  3. 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)
  4. Base drainage - the area below the concrete must not be subject to frost movement
  5. Surface - surface must be totally smooth and flat equivalent to the desired finished surface
  6. 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.
  7. 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.

 Sealers 

  • Product may be sealed for aesthetic or cleanliness reasons but it is not required
  • Use any sealer approved for concrete pavers
  • Select type for desired aesthetics
  • Product must be cleaned before sealing
  • Always read and follow manufacturer’s application procedures
  • Always test a small area to make sure the results are as expected

RELATED LITERATURE
Premium Pavers: Why Should You Recommend Them on Every Hardscape Project?
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.
Why You Should Invest in a UniLyft & How Easy It Is to Use
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.
Stone Dust Doesn’t Belong Under Pavers. Here’s Why.
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.
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.
