The substantial proportions and unique color blending of Town Hall is modelled after historic North American clay street pavers. The look of Town Hall is timeless, which makes it a popular choice for driveways, patios, walkways and more, in either traditional or permeable applications. The rich colors and classic shape also make it popular for borders, banding and other accents in pavers, walls and vertical features. To ensure projects receive a random appearance, Town Hall textures were cast from a multitude of different surfaces using Reala™ Technology, and Ultima™ Concrete Technology was used to create superior durability. The result is vintage, streetscape charm that stands the test of time.
Town Hall pavers combine the timeless beauty of historic clay bricks with the functionality, performance and colorfastness that only Elegance™pavers from Unilock can deliver. This paver can be used for both permeable and non-permeable projects.
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.
