For non-vehicular applications such as embankment stabilization, the maximum slope is determined by the angle of repose of the bedding sand, typically around 35 to 38 degrees. For vehicular traffic, the highest slope in use is 18% (about 10 degrees) in a street in Colma, California. Special consideration is given to the drainage of the bedding sand at the bottom of the slope.

StreetPrint? can be installed very quickly with relatively little disruption, so it is usually much less costly and disruptive than concrete alternatives. StreetPrint? uses asphalt as its base. Asphalt is a flexible surface that is more likely to accept shifting due to weather extremes and can resist cracking commonly associated with other paving systems. Vehicle braking/accelerating and steering will not shift or break StreetPrint?, as often happens with brick pavers. See similar questions...

Concrete is an inexpensive and durable option, but it will crack. Pavers are more expensive but last longer, provide more of an interest from a design perspective, and are easily repaired if earth shifting occurs. Stone creates a beautiful and natural look but is the most expensive option. Many stone applications can be sandset, which is flexible to ground shifting. Occasionally stone requires a mortar setting, which is less tolerant of ground shifting. See similar questions...

In Europe, they have seen pavers last over 50 years. This is much longer than other pavements under normal residential use. See similar questions...

There is no way that we can prevent oil from dripping on concrete pavers. Yet, because pavers are more dense than regular poured concrete, they will be easier to clean if the stain is cleaned soon after it happens. If you are working around your paver patio, walkway, or driveway with paint, cement, or mortar and should accidentally spill this on your paver surface, you should clean it off right away before it has a chance to dry. Otherwise, it will stain your pavers. See similar questions...

The joints between pavers eliminate cracking that is normal to conventional asphalt and concrete pavements. Yes, if necessary. That is an item we will discuss with you when we come out to give you an estimate. See similar questions...

You will never see a crack running through a paver patio or across a paver walk, and of course pavers offer more design diversity. Back to top See similar questions...

Concrete pavers offer more design options (more colors and sizes), whereas clay pavers offer less maintenance. The cost is about the same. Concrete pavers tend to lay a bit snugger, making tighter joints and a more consistently flat surface. Clay pavers however hold their color much the use of chemical sealers. Although the concrete is died straight through the paver, the die still has a tendency to wash off the top over time. See similar questions...

Sealing is not essential in many applications but it offers some benefits like making spills and stains easier to remove. Liquid sealers are applied after the pavers are installed and are cleaned. Once applied, the sealers soak into the concrete and into the joints. The sealers in the joints help keep the joint sand in place and prevent weeds and ants, and sealers are essential for areas around swimming pools. See similar questions...

Pavers can be plowed or shoveled just like concrete or asphalt flooring. Do not chop or use sharp objects to break away any ice on the surface of your paved surface. Although salt will not damage your pavers, non-corrosive de-icing products are recommended See similar questions...

Absolutely! 12"-18" of compacted base material is recommended for residential driveways. A standard 2-3/8 thick paver can be used for light vehicular (cars and pickup truck) applications. A Colonial random pattern is most popular in these situations. See similar questions...

There is no problem with using pavers around trees. You should consider leaving a 4-foot area between the tree and the pavers. Consult your local landscaper for these recommendations. See similar questions...

Yes, you can put pavers over concrete. There can be cracks in the old patio as long as it is still level and has not "heaved" up in any areas. Concrete makes a great base for our products. We will still need to retain the border of your project. See similar questions...

slopes are the preferred limit. However, 1:1 slopes can be designed provided a proper stability analysis has been performed. Constructability also becomes an issue on steep (1:1) slopes with vertical elevations over 10' and will likely necessitate cables for placement. See similar questions...

Never mow on a slope greater than 15?. Always mow across the face of slopes, never up and down or diagonally. Do not attempt sudden starts or stops when mowing or on a slope. Avoid sudden turns and use extreme caution when changing directions on a slope. See similar questions...

Slope is defined as the change in height (rise) as compared to the distance up the roof area (run) and is measured in inches. For example, a slope of 4:12 means 4 inches of rise for every 12 inches in run. Some people call slope "pitch", but the technically correct term is "slope". See similar questions...

Radar signal penetration is a function of the material properties (aggregate, moisture content, amount of rebar, etc.) but typically we can map 300 to 350 mm deep in concrete that is well aged. See similar questions...

Yes, it requires a Zoning Permit ($75) to determine impervious coverage restrictions for the zoning district you are located in. See similar questions...

The main reason that people seal their Brick Pavers or Decorative Concrete is to create an enhanced "wet" look. This will deepen the colors and add a satin to semi gloss shine. It will also protect the pavers and cement from spills, oils, and the degrading effects of the sun. See similar questions...
