Why Acker-Stone?

Acker-Stone is not the average paver manufacturer, but a bit of a hybrid. We make traditional pavers but it’s in our ability to customize that makes us unique. With a large array of aggregates, special finishes, large format sizes, extensive color pallet, custom color capabilities, and through mix technology, we showcase endless design options. Our company caters to landscape architects, designers, and residential homeowners alike with looks that range from old world charm to contemporary and sleek designs. This is why we ask you experience the Art of Acker-Stone.

Through Mix vs. Face Mix Technology

Both through mix and face mix pavers are manufactured at Acker-Stone. Our face mix technology is next level due to the fine aggregates, sand, cement, reduced amounts of larger aggregates, a harder sand mixture and a high dose of pigment within the top ½” potion of the paver. This results in richer, more vibrant colors, a smoother and more refined texture, color longevity and a more wear resistant surface. Through mix pavers are the industry standard and constitute color throughout. The face of the paver is more coarse in nature and the larger aggregates on the top portion of the pavers are exposed immediately. The shades and depth of color may vary greatly due to this.

Is the base material important?

The base material absorbs the loads applied to the surface of the pavers. Without the compacted base the pavers fail as a result of rutting or sinking.

What type of material is used for the base?

The proper material is a crushed angular gravel mix typically referred to as a ‘crushed miscellaneous’ or ‘3/4 minus’.

What is the geotextile and is it necessary?

Geotextile is a heavy fabric that functions similar to that of a coffee filter. As water goes in and through the base, it prevents the base from migrating into the existing soils. It may be necessary in areas with high water tables.

What sand do I need to use?

ICPI guidelines should be followed by all installers. Please refer to ICPI Tech Spec 17 for further details. The bedding sands should conform to ASTM C33 or CSA A23.1

Is the bedding sand used for leveling the pavers?

The bedding sand should be loosely and evenly screeded at a depth of 1 to 1 1/2 inches. During the first compaction, bedding sand fills the joints from the bottom up and evens out any minor height differences between pavers. Bedding sand should not be used to bring up elevations and depressions in the base material.

Is the joint sand different from the bedding sand?

Bedding sand can be used to fill the joints, but may be difficult to sweep and vibrate into the joints. Dry bagged joint sands are typically finer, and sweep and vibrate easily into the joints ensuring good interlock.

Are there dye lots with pavers?

Although typically not referred to as dye lots, pavers are made of natural materials (cement and aggregates) which may cause minor color variations between pallets or batches. A contractor should lay the pavers from various pallets simultaneously to assure a good color mix.

Is the edge restraint important?

Without the edge restraint the pavers will not remain interlocked and will fail. There are many different types of edge restraints commonly used. The most common are metal, plastic, or concrete.

Do I need to seal the pavers?

Sealers offer benefits including color enhancement, joint sand stabilizing, and stain resistance. Areas such as pool decks, driveways, and backyard patios are commonly sealed to reduce staining.
