THINGS TO KNOW

DuraMat

DuraMat is designed as an interlocking puzzle-like unit which locks with each neighboring stone to form a strong cohesive mat for use in erosion control applications and retention pond floors.

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 only.

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). When available, use architect’s or engineer’s specific site engineering for installation.

Standard Bedding Course – no bedding required. Install directly on base material.

Jointing Material and Joint Stabilization - Fill all holes with free-draining aggregate or as specified by engineer.

Handling – This product is heavy and a two-man clamp is recommended for placement.

Edge Restraint - A concrete curb or a “sub-surface concrete wedge” can also be installed to retain the edge.

Paver Compaction - For the final compaction, a “rubber roller compactor” will give you the best results without breaking the units.

Cleaners – Not applicable

Sealers - Not applicable

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).

Classic
Design trends rise and fall, but for something to be considered classic it needs to be both timeless and elegant. No two words could better describe the Unilock Classic paver. Available in a wide variety of shapes and styles, Classic pavers are made using a proven manufacturing process—blending cement, colors, and stone aggregates into a single batch and distributing the mix throughout the finished paver. This ensures a uniform look that is strong but capable of being formed into the wide variety of styles Classic is known for.

The Advantages of Installing Permeable Pavements
Permeable pavers look similar in size, shape, color, and finish to traditional pavers. The difference? They are designed with special spacer bars that increase the joint size between pavers.
Permeable Pavers and Rainwater Harvesting
There’s an emerging environmental consciousness across society that’s becoming ever more mainstream, and it’s expressed with the most clarity by the way consumers wield their wallets. It’s as much about how purchases fit into an eco-friendly lifestyle as it is about the products and services themselves.

What risks and benefits are there in providing sustainable outdoor living designs for homeowners? What kinds of sustainable material choices are available? These are questions worth evaluating when deciding how to operationalize sustainability in your landscape contracting business.
