Cambridge Has The Joint Sand Stabilization Program
That’s Right For Any Need
By Steve Jones,
President PAVE TECH

SandLOCK is the only brand that offers both PREMIX and ADDITIVE. These field-proven organic products are economical and better environmental alternatives to chemical joint stabilizers. Ideal for flexible and semi-rigid pavingstone systems, they form a natural “glue” in the joints while preventing sand loss due to wind, traffic and moisture. Unlike water-dispersed, polymer-based stabilizers, the material in SandLOCK will not dilute. The absorbent material — comprised of tiny sponge-like elements — swells and binds to provide a greater resistance to washout. Only minimal water infiltration is allowed through the joints. Water-based polymers dissolve to form a paste compromising performance. The sand may crack and wash out of the joints over time. Compare these other features:
• Non-toxic and odorless… safe for use around plants, animals and people.
• No harsh chemicals are needed prior to installation.
• Non-staining and will not alter the paver’s original color.
• No surface residue remains if instructions are followed.
• Pavement is ready for traffic immediately.
• Remains flexible during thermal movement.
• Will not chip out or break apart from wear… any moisture instantly heals cracks.
• Works in all climactic conditions… will not break down from ultraviolet light.
• Reduces weed growth from wind blown germination and is effective against ants.

Choose SandLOCK PREMIX
SandLOCK PREMIX is the only organic, premixed, structural joint sand. Be especially cautious of low grade, low priced premixed products that promise extra strength. Brands that cut costs by reducing the additive ratio will not only under-perform, but may not work… period.

SandLOCK PREMIX activates by flooding the surface with water… no additional clean up is needed after setting. Save time … no mixing on-site. Save labor… dry SandLOCK PREMIX sweeps faster. Reduce risk… leave proper mixing ratios to PAVE TECH, the industry experts. SandLOCK PREMIX is packaged in conveniently sized 50 lb. bags. Bags must be stored in a dry area.

Structural sand with properly sized grains and gradation is critical to optimum performance. PAVE TECH ensures that the sand used in SandLOCK PREMIX is the absolute finest structural sand available in the region.

Compare for yourself; conduct a Field Test using SandLOCK PREMIX and another brand:
• Add a small amount of water to a competitor’s brand of premixed stabilized sand and roll into the size of a meatball.
• If it is slimy on the outside of the ball, there is too much additive in the premix and performance will be compromised.
• If you can poke the ball (as if it were the Pillsbury Doughboy) without it cracking, the ratio of additive to sand is correct. PREMIX has been tested to assure a perfect ratio every time.

Choose SandLOCK ADDITIVE
Still the most economical method, SandLOCK ADDITIVE is an ideal choice when mixing a joint sand stabilizer with joint sand on the job site. SandLOCK ADDITIVE is the only organic additive on the market today. It is available in 2- and 25 lb. pails. Compaction and stabilization are both done at once. After pavers are installed, simply mix approximately 3 – 4 pounds of SandLOCK ADDITIVE for every 100 pounds of joint sand, then sweep, compact and activate by flooding with water after all material is swept clean from the surface. Allow to set. No additional steps are required.

How To Build Square Corners, Finished End Walls And Fixed Length Walls With MaytRx® Double-Sided, Multi-Face Wall Units

MAYTX®/PYZIQUE

Rather than having to purchase corner units separately as with other wall systems, contractors can create corners from standard wall stones. Along with its finished double-sides and five faces, Cambridge MaytRx offers real value-added advantages. The five stone system is designed to make building square corners and finished ends as easy as splitting a MaytRx A, B or Y stone. First, split each of these wall stones from front to back along the groove that is provided on the top. Retaining wall adhesive should be used
on corners.

Use a block splitter capable of cutting a concrete product that is 6 inches high. The “new” face will have the same texture as the MaytRx Split Face. Hammering on the new face will “distress” the face to match MaytRx Renaissance. Splitting with a hammer and a mason chisel is an alternative but will require more time and the split will not be as precise. Saw cutting is another option for making half stones but should only be used if the cut stone is to be placed within the wall — not on ends, corners or columns because the texture of the new face will not match the rest of the facing on the wall.

To achieve a finished face on both sides of the square corner or on the end of the wall, set any of six wall stone pieces (two each from stones A, B, and Y) at the corner or end. Start each layer, after the base course, at the square corner or end and build away from this point.

Fixed length walls are special applications that have two square corners or a square corner and a fixed end. The wall between the two ends must be of a fixed length for each layer. For each layer on a fixed length wall, start at both a square corner and finished end and build toward the middle.

If the full or split wall stones do not exactly fit the final gap in the layer, there are two alternatives to consider. The first alternative is to change one of the wall stones adjacent to the gap so that the new gap will be the size of one of the faces of an A, B, X or Y MaytRx wall stone or one of the six half wall stones. The second alternative is to measure the gap and split or saw cut a piece off a MaytRx wall stone to fit the gap exactly. Splitting a filler wall stone to 2 inches wide or less is difficult. A thin filler wall stone will often break before it is set. If the gap is 2 inches or less, change one of the wall stones on one side of the gap to make it at least 3 inches wide. (top)

a winning competitive edge.

School For Advanced Segmental Paving Opens Its Doors

Located at the PAVE TECH Training Center in Franksville, Wisconsin, the new “School for Advanced Segmental Paving” is the first of its kind in North America. The 1000 sq. ft. multimedia conference/training room was completed at the beginning of April, and the first meeting of the Founding Board members was held on April 16, 2005. “We are pleased to announce that both the facility and the meeting exceeded our expectations,” reported Steve Jones, PAVE TECH’s president. Progress is continuing on the program, which will provide indoor, hands-on training and educational opportunities mainly for skilled foremen, superintendents and field oriented company owners. A portion of PAVE TECH’s 14,000 sq. ft. warehouse expansion will be set-up specifically for hands-on work.

“We are very proud of our long association with PAVE TECH,” said Charles Gamarekian on behalf of Cambridge, “and I’m pleased to have been asked to chair the Training Center’s Scholarship and Fundraising Program.”

The curriculum is tailored to experienced, professional pavingstone contractors and not designed for basic training. New paver installers are encouraged to refer to the “Vocational Student Training Manual” published by PAVE TECH and attend Cambridge-sponsored ICPI Installer Programs.

PAVE TECH is currently accepting sponsors and classes will be scheduled primarily off-season during winter months starting in December 2005. Please check www.pavetech.com/school.htm often for updates. (top)

The Twelve Value-Added PREMIUMS of Cambridge MaytRx Double-Sided, Multi-Face Wall Systems

By Paul Adam, C.E.,
Inventor of MaytRx® Wall System

1. Corners are made by splitting existing units and therefore, the need to order and store additional pallets containing corner units is eliminated. This is an important PREMIUM for stocking and non-stocking Cambridge Distributors.
Tell contractors how integrated corners also assure uniformity of color throughout the finished wall.

2. Cambridge Pavingstone color matching is a big PREMIUM for stocking Cambridge distributors. Tell contractors how easy it is to offer their customers a truly finished look — a wall system that actually matches the pavers.

3. Double sides are an important PREMIUM because of the many design
possibilities not available with single-sided walls. Tell contractors that they get
PREMIUM value with little or no premium pricing over single walls.

4. MaytRx double-sided capstones can also be used as caps for Cambridge Pyzique®. This is an important PREMIUM even if you don’t buy or stock the entire MaytRx system. Tell contractors to consider this as an option
when building Cambridge Pyzique walls.

5. All four shapes (offering five face sizes) are conveniently packaged on the same pallet. This important PREMIUM conserves yard space and makes ordering a lot easier. Tell contractors how the building process is accelerated because the installer easily accesses all four shapes used in the system.

6. MaytRx Caps can be soldiered in a freestanding wall without cutting. Soldiering is achieved by sporadically setting some of the wall stones vertically (on end). This feature creates another PREMIUM value. Tell contractors how this can save time because cutting is not necessary.

7. If needed, the MaytRx “A” Wall Stone shape and Cap Stone can be soldiered in a landscaping wall for a real PREMIUM appearance. Note also that the MaytRx Cap Stone is 11 in. deep while other MaytRx wall stones are 10 in. deep. Tell contractors how unique placements such as these can add extra dimension and more of the look of a natural stonewall.

8. The sides of MaytRx Wall Stones are manufactured with a smooth machine finish for a tight fit. Tell contractors how this PREMIUM can clinch a sale with customers who prefer a system that does not allow daylight to be seen between the butting points of two wall stones.

9. MaytRx Wall Systems offer two textures – Split Face and Renaissance – in a large variety of colors. Tell contractors that this PREMIUM choice is hard to find in other brands.

10. Cambridge offers free help in pre-bid engineered walls and engineering referrals for stamped drawings. This PREMIUM removes the fear often connected with selling engineered walls. Tell contractors that it is possible to get larger type wall projects without liability or hassle.

11. Cambridge transports Cambridge MaytRx Wall Stones on the same truck as Cambridge Pavingstones — a PREMIUM that translates to efficient logistics and maximum use of space on trailers. This is a PREMIUM for smaller dealers. Tell contractors how this helps keep MaytRx competitively priced.

12. As the inventor of the MaytRx Wall System, I am available for technical questions — almost 24/7. Tell contractors how this PREMIUM value that provides straight answers and fast solutions, is also available to them by calling Paul Adam at the MaytRx Hotline: 515.720.8601. (top)
