What is TRUEGRID?

TRUEGRID is an eco-friendly paving alternative to concrete and asphalt that provides stability and storm water detention. TRUEGRID is super durable and storm water permeable to reduce flooding as well as stop rutting and erosion by providing structure for ground stabilization. Park/drive on the TRUEGRID surface and detain water underneath.

What makes TRUEGRID better than the rest?

TRUEGRID is the world’s strongest permeable paver at the best price. TRUEGRID has the highest possible compression strength and durability. TRUEGRID has the highest permeability and a maintenance free design. TRUEGRID is easy to install and the most affordable.

How heavy a load can TRUEGRID handle?

TRUEGRID can easily handle anything on the road or off road with over a million psf of load capacity.

Can TRUEGRID handle heavy traffic?

Yes! Better than any other system by far. There are multiple TRUEGRID installations that support over 300 18- wheelers traffic daily and heavy military vehicles. TRUEGRID has also performed well in scores of high end high traffic commercial drive lanes and lots.

How long will my TRUEGRID last?

25 to 60 plus years depending on traffic and application. TRUEGRID will typically outlast asphalt and last as long as or longer than concrete.

What makes TRUEGRID stand out as a paver?

TRUEGRID is the world’s strongest permeable paver, will outlast asphalt; can withstand the heaviest of loads and traffic. TRUEGRID is super simple to install and requires no staking or tools. It results in a more natural looking surface, either grass or gravel.

How do I install TRUEGRID?

The TRUEGRID System was developed to be very simple to install. Any contractor, landscaper, or DIY’er can easily do it the first time with little direction. We are also available for any needed guidance. DIY Install video coming soon.

Can you recommend a contractor to install TRUEGRID?

Email or call us for a preferred installer in your area. If you have a paving contractor or landscaper who you would like to use for your TRUEGRID project, feel free to have him contact us directly for installation guidelines.

Can you grow grass through TRUEGRID?

Yes. You may seed or use sod with TRUEGRID.

Can I seed or sod TRUEGRID?

Yes, TRUEGRID may be seeded or sodded.

What kind of rock should I use for base or fill material?

Base rock for detention and added drainage considerations should be angular, washed rock, 1” and under. If sub-surface detention is not a factor in your project, a compacted base such as recycled concrete or other road bases can be used.

You may use a wide variety of fill rock depending on what is locally available in your area and what the desired cosmetics of your project are. For ADA compliance it is best to use ½” diameter or smaller fill rock.

How to prevent weeds from growing in my installation?

You may use a porous landscape fabric between the soil sub-grade and the rock base to prevent weeds from growing from underneath.

How deep should my base layer be?

Typically, 4” to 6”. TRUEGRID can put installed directly without base on top of a compacted soil or aggregate base if additional detention beyond the 1.8” of TRUEGRID is not needed. Also, the sub-base depth can be increased beyond 6” if increased detention volume is desired.

Does TRUEGRID need edging when installed next to other materials?

No, simply transition or grade to surrounding landscape or hardscape.

Do I have to stake TRUEGRID to the ground?

No. TRUEGRID is robust and does not require staking. (Note: Severe slopes of 15% or steeper may require some staking.)

Can TRUEGRID be installed on sloped ground?

Yes. Generally, less than 15% slopes do not require staking.

Does TRUEGRID require extra clips or stakes to lock in place like other plastic systems?

No, TRUEGRID requires no clips or stakes.

What maintenance requirements are there for TRUEGRID?

None. TRUEGRID is a maintenance free system.

Is TRUEGRID permitted in my area?

Typically pervious surfaces are encouraged by most municipalities to reduce storm water runoff and flooding. Check with your local permit office or your contractor for local coding. If we can help, please call or email us.

Where is TRUEGRID made?

TRUEGRID is made in the U.S.A.

Is TRUEGRID ADA compliant?

Yes, TRUEGRID projects are ADA complaint when transitions are kept less than ½” and aggregate of ½” or under is used.

What is TRUEGRID warranty?

Five year warranty for workmanship and manufacturer’s defects. Check the installation contractor for installation warranty. TRUEGRID does not directly provide construction or installation services and does not warranty installation.

Can TRUEGRID be snowplowed?

Yes (View Technical Document). Skids on the corners of plow blades to raise the blades are recommended. Most plows have these already installed to prevent blade damage to asphalt surfaces.

What types of soil does TRUEGRID work with?

TRUEGRID works with all soils and in all climates. For unstable soils a geo-grid mesh or permeable pinpoint fabric may be helpful between the soil and the rock base.

Can TRUEGRID be installed in any climate?

Yes. The temperature range of the plastic is -58F to 198F.

How quickly can I install TRUEGRID?

Fast! The panels are pre-assembled in 4’x 4’ sheets. TRUEGRID can be installed at over 1000 sf per man-hour. Also, TRUEGRID is plenty strong enough to drive full gravel trucks on before the rock fill which speeds up the construction of a project tremendously.

How is TRUEGRID eco-friendly?

What are the environmental benefits of TRUEGRID? TRUEGRID is green from manufacturing through end use. TRUEGRID is made from 100% post consumer recycled HDPE. Using TRUEGRID allows storm water to permeate through the aggregate or grass fill so bioremediation can help remove pollutants from the water before it reaches the water table (Environment). Also, substituting TRUEGRID for concrete eliminates the CO2 emissions from the manufacture of cement. Enter the square feet of your project on our quote request page to calculate your environmental impact and benefits for your specific project (this feature coming soon).

Can I order TRUEGRID in other colors?

Other colors can be special ordered. Because we must use virgin plastic there is an up-charge and MOQ of 10,000 sf.

How do I stripe my parking lot?

 

Two ways. SuperSpotsTM are made to delineate parking are lock into the grid. Alternatively, you may paint stripes directly on the TRUEGRIDS’s encapsulated, non-overfilled gravel; these eventually may require repainting depending on traffic and wear.
How long will TRUEGRID stay permeable?

For the life of the installation when filled with the recommended clean, washed fill aggregate.

Does TRUEGRID help with flooding?

Yes, TRUEGRID reduces storm water runoff by providing water detention volume in the gird and the sub-base.

Can TRUEGRID be used in equine/livestock applications?

Yes, TRUEGRID prevents muddy stalls, trailways and pens, helping to prevent hoof disease. (Projects page photos)

Can TRUEGRID be used in fire lanes?

Yes, TRUEGRID is the perfect option to provide soil stabilization for fire lanes and fire engines and emergency vehicles. TRUEGRID meets code and has been installed in many such projects across the country. TRUEGRID Fire Lane typical cross sections can be found here.

Is TRUEGRID H20 and HS20 rated?

Yes.

How can I get detention space under the surface of TRUEGRID?

By using angular, clean stone 1” or under you can create detention which is calculated by multiplying the cubic feet of storage by 40%. This represents the void space in the rock sub- base and the detention capacity.

How can I transition a TRUEGRID lot to a concrete or asphalt lot?

Install TRUEGRID 1/8” to ¼” below the concrete or asphalt where it transitions to TRUEGRID. See transition detail here.

Can TRUEGRID be cut to fit any shape?

Yes, TRUEGRID can be easily cut on site with a handheld power saw.

What applications can TRUEGRID be used in?

Virtually any paving application except for high speed highways. Parking lots, equipment storage yards, driveways, fire lanes, sports fields, overflow parking, job sites, oil field rig sites, pathways, ADA compliant surfaces, horse and livestock stalls and trails, event parking, entertainment venues for parking and foot traffic, landscaping, temporary parking or heavy vehicle traffic, equipment pads, hot tub pads, pool skirting, golf course paths.

How is TRUEGRID manufactured?

TRUEGRID is injection molded in the USA from 100% post consumer recycled HDPE.

What is HDPE?

High density polyethylene, a tough, inert, groundwater neutral material.
