Gravel-Lok user testimonial


We purchased the Gravel-Lok about a month or so ago, and it worked out really well. We redid our pathway to the front door entrance. It looks even better than we expected. The amber cast works great with our overall landscape tone and sets off nicely against the green lawn and stone house.

Thank you so much for an awesome product and solution.

Gravel-Lok is great for Xeriscaping!

(via - solutions for sustainable living)

Xeriscaping refers to the conservation of water through creative landscaping.

Originally developed for drought-afflicted areas, the principles of xeriscape today have an ever broadening appeal. With water now considered an expensive and limited resource, all landscaping projects, residential or commercial, can benefit from this alternative.

Xeriscapes do not have a single look - almost any landscaping style can be achieved. The principles can be applied to all or part of a yard, in any geographic region of North America.

Xeriscape Benefits

Saves Water. For most of North America, over 50% of residential water used is applied to landscape and lawns. Xeriscape can reduce landscape water use by 50 - 75%.

Less Maintenance. Aside from occasional pruning and weeding, maintenance is minimal. Watering requirements are low, and can be met with simple irrigation systems.

No Fertilizers or Pesticides. Using plants native to your area will eliminate the need for chemical supplements. Sufficient nutrients are provided by healthy organic soil.

Improves Property Value. A good Xeriscape can raise property values which more than offset the cost of installation. Protect your landscaping investment by drought-proofing it.

Pollution Free. Fossil fuel consumption from gas mowers is minimized or eliminated with minimal turf areas. Small turf areas can be maintained with a reel mower.

Provides Wildlife Habitat. Use of native plants, shrubs and trees offer a familiar and varied habitat for local wildlife.

C&S Companies install Gravel-Lok pathway in Syracuse NY

C&S Companies, ranked as one of the nation's leading engineering and architectural design firms, recently hired Anthony DeMarco & Sons to install a 2000 sf Gravel-Lok pathway at their campus headquarters in Syracuse, NY.  C&S has been in business for 42 years, has 8 offices throughout the US, and employs over 400 people.

They learned about Gravel-Lok through Paragon Supply in Syracuse, NY, an authorized dealer of Gravel-Lok C&S prides themselves on advancing creative ideas and practical solutions and found Gravel-Lok to be appealing for its "green" feature of permeability combined with the beautiful look of natural stone.

The pathway meanders through their campus and past a sediment pond.  They used a non-woven geotextile fabric, Cell-Tek's 3" cell depth recycled Load Support Grid (LSG-3), filled the cells with #57 clean, washed, angular stone, and added a layer of 1/2" size decorative stone before applying the Gravel-Lok liquid to bond the stones together.

Gravel-Lok News: Stone Scaping with Gravel-Lok


Businesses strive for eco-friendliness

  When environmentalist and lawyer Clay Henderson began touting eco-friendly ideas more than a decade ago, he said he was "swimming upstream."
Now such efforts by businesses to be greener are part of the norm.
"There clearly seems to be a realization that the more you conserve, the more it will save you money," said Henderson.
Henderson said he is glad to see so many businesses helping to save the environment. "You are seeing more and more green businesses," he said, while acknowledging an improved bottom line is at the heart of the movement

Job Corps students show off pavement for Earth Week

LONG BEACH - Job Corps students celebrated Earth Week Tuesday by demonstrating the advantages of using permeable pavement instead of concrete to keep polluted runoff from reaching the sea. The display at the Long Beach Job Corps Center was part of a week-long attempt to raise awareness of the environment, sustainability and climate change.

Earth Day is Thursday and Earth Week continues through Sunday.

Water hitting the permeable pavement sinks through the layers, returning to the ground instead of running off into storm drains and carrying bacteria or trash to rivers and oceans, Meredith Reynolds, Long Beach Sustainability Coordinator, said.

You and storm water: A major source of pollution

via McClatchy Newspapers; By Terri Bennett

How would you feel if you knew that you and your neighbors are the biggest source of water pollution in the U.S.? Well, it's true.
It's generally not intentional, but each day we all do things that add up to one big problem.

Storm water runoff is just what it sounds like: water from rain or snowmelt that flows over the ground. Impervious surfaces like driveways, streets and parking lots prevent storm water from being absorbed into the ground, contributing to the flow of runoff.

Storm water flows downhill to the nearest storm drain. What most people don't understand is that anything that enters a storm drain flows untreated into a nearby creek, river or lake. These rivers and lakes are the source of drinking water to 85 percent of Americans and a valued resource for swimming, boating or fishing for all of us.

Rainwater-absorbing lot designed to curb runoff

The new lot will have a drainage system that will absorb storm water and cut down on the amount of runoff into a nearby lake.
The work is part of a federally funded project aimed at improving water quality in the small Iroquois Lake in the southeast part of the park.
The Olmsted Conservancy received a $1.4 million grant from the Environmental Protection Agency to cover most of the work at Iroquois and some similar work to help Willow Pond at Cherokee Park. The money was secured by former U.S. Rep. Anne Northup while she was in Congress.
The expanded amphitheater parking lot at Iroquois is expected to be complete by early summer. The Cherokee project will be complete later this spring when the final native plants are added.

Coming Together for Clean Water - Stormwater Pollution

"What, where, and how communities build will affect their residents’ lives including access to clean water. More pavement and non-porous surfaces mean less area where water can soak into the ground, where it recharges our water supplies and nurtures ecosystems. Stormwater that isn’t absorbed runs over these developed areas, picking up contaminants and sediments that eventually flow into rivers and streams."

'Building Your Green Home' panel discussion

A four-bedroom, 4,200-square-foot home to be built later this year in Upper Makefield was designed to rest lightly on the land, starting with high-density cement-panel basement walls set in gravel.

The building will be constructed of structural insulated panels that minimize wood use and chemical off-gassing. It will have super-high-efficiency windows, ground source heat, a storm water cistern for irrigation, an upgraded septic system, native, drought-resistant landscaping instead of a lawn, pervious paving and durable fiber-cement siding that uses recycled wood.

Paving material that lets rainwater percolate into the ground is under consideration, whether in the form of pervious asphalt or manufactured paving stones.

Hartke says his Holicong-based architectural partnership found it difficult to find pervious asphalt to pave its own parking lot about seven years ago, but, he says, "Now, you can find a supplier. Almost all asphalt manufacturers can provide it."

Will the system stay permeable forever?

As a permeable system the Gravel-Lok bonded pavement is full of voids which allow water to pass through. Like any other permeable pavement those same voids will eventually get clogged with dirt, dust, debris and this will reduce permeability over time . There are vacuum services specifically designed for porous pavements which are becoming increasingly popular. Recommended cleaning depends on site conditions and the amount of sediments the system is exposed to. Without maintenance, typical permeable systems become completely clogged within 5 - 7 years.

What type of maintenance can I expect with the Gravel-Lok pavement?

Gravel-Lok is relatively maintenance-free and no annual treatment is necessary. If the system is being used for vehicular traffic some loose stones may occur depending on the type of stone used and degree of abuse. Typically, you can expect about 1% of stones to dislodge or become loose in about a 5 year period. If desired, a disturbed area can be treated with more Gravel-Lok.

Will snow plowing affect the pavement? What about salt?

Snow plowing has the potential to damage the pavement but this can be minimized if you use a rubber blade on the plow and exercise caution. Obviously, the type of stones will make a difference too. Harder stones such as marble and granite will be more durable. Softer stones are going to be more vulnerable. A snowblower would be a safe machine to use. Additionally, it is completely safe to apply salt for melting ice and snow.

How does Gravel-Lok perform under freeze/thaw cycles?

If installed properly, with adequate base materials that allow for drainage, Gravel-Lok will withstand freeze/thaw cycles. If freeze/thaw cycles are a concern then we suggest creating expansion joints (saw cut) at appropriate intervals.

What type of maintenance can I expect with the Gravel-Lok pavement?

Gravel-Lok is designed to be maintenance-free and no annual treatment is necessary. If the system is being used for vehicular traffic some loose stones may occur depending on the type of stone used and degree of abuse. Typically, you can expect about 1% of stones to break off or become loose in about a 5 year period. If desired, a disturbed area can be treated with more Gravel-Lok.

How long will it last?

If installed properly the Gravel-Lok pavement will have the same lifespan as other forms of pavement such as concrete or asphalt.

How strong is Gravel-Lok?

Gravel-Lok is a system. The top layer of bonded aggregates has the structural integrity of asphalt. The key to any pavement surface is the foundation it is built on. Below the bonded aggregates is Cell Tek's Geocellular Confinement System which constrains open-graded aggregates. The passive resistance of the infilled cells prevents lateral movement and distributes the load over a wider area. The system also reduces the impact on the subgrade up to 28% while reducing the amount of base material required.

Leveling Stones with a Lawn Roller

A lawn roller is the best solution for leveling out stones prior to installing the Gravel-Lok bonding agent.  The roller flattens out the stones helping to create the smoothest surface possible.

Cured Product: MSDS

One of the primary concerns when placing permeable materials near plant life and over soil is the longterm safety of the product. Will the product leach into the ground? Is it carcinogenic? These are questions commonly asked by design professional when considering which product to use. On the Cell-Tek website you can find posted a copy of the Gravel-Lok MSDS (cured Product) report.

In the report you will discover that Gravel-Lok in its cured state becomes an inert substance meaning it becomes chemically inactive. The physical state is a solid which is not soluble in water. The cured product is stable and not reactive.

The toxicological findings show that it is not considered a carcinogen with the following agencies:
1. International Agency for Research on Cancer (IARC)
2. National Toxicology Program (NTP)
3. Occupational Safety and Health Administration (OSHA)

Building a Tradeshow Booth: Mants Show 2010

This year for the Mants show we created a puzzle display layout.  The reason for this when rectangular samples are laid out most people think that we are making block paving stones.  We wanted to create an interesting design that poised the question:  What is this?
It worked the audience found our display puzzling and attractive and was a huge hit at the Mants show in Baltimore, Maryland.

Step 1:  
We projected on two sheets of plywood a puzzle layout.  We traced the outline with a magic marker

Step 2:
The plywood was cut out into the puzzle shapes.  The puzzle was then put back together and a 3 inch aluminum divider was put in place to separate the different aggregates used for each puzzle piece.

We were unable to get the puzzle pieces apart so we picked up the whole display with a fork lift and loaded it on a pick up truck and brought the whole unit to the tradeshow.  Weighing in at 1600 lbs. it was quite a venture.

The Finished Tradeshow Booth
