Why do I need Load Support Grid?

The LSG system confines materials and prevents lateral movement away from the applied load. The stabilizer grid acts as a large mat, by spreading the load over an extended area while increasing the load bearing capacity of the surface.

Bottom line, load support grid makes a strong foundation that will prevent rutting .

What sizes do the grids come in?

Each expanded panel of LSG Load Support Grid is 9′ L x 24′ W (215 square feet) and comes in one of three depths; 3″, 4″ or 6″

What is the minimum order quantity?

You can purchase as little as one grid (9′ x 24′, 215 sf).

What material is the LSG grid made of?

LSG Load Support Grid is made from virgin HDPE (high density polyethelyne).

How do I know what cell depth to use for my project?

You can always give us a ring at the office or shoot us an e-mail to discuss your project in detail but a good rule of thumb is:

LSG-3 is good for patios and walkways with pedestrian traffic up to 8,000 lbs.

LSG-4 is good for standard cars and pickup trucks up to 40,000 lbs.

LSG-6 is good for heavy trucks and fire access up to 80,000 lbs.

What if I have a slope that I will drive on?

It is OK! LSG Load Support Grid will work for slope protection and also provide the load support needed for a drivable surface.

What other materials do I need for my project?

Each project is different. The materials needed depends on what the top surface will be. Always double check with us but use this as a quick guide:

Loose gravel surface:

  • Non-woven geotextile fabric
  • LSG Load Support Grid
  • Rebar J-Hooks to keep the grids pinned down
  • Stapler to connect grids together (if needed)
  • Infill stone

Grassy surface:

  • Triax Geogrid
  • LSG Load Support Grid
  • Rebar J-Hooks to keep the grids pined down
  • Stapler to connect the grids together (if needed)
  • 50/50 mix of stone and soil as the infill

Paver surface:

  • Non-woven geotextile fabric
  • LSG Load Support Grid
  • Stapler to connect the grids together (if needed)
  • Stone infill
  • Pavers and bedding sand

Gravel-Lok bonded gravel surface:

  • Non-woven geotextile fabric
  • LSG Load Support Grid
  • Stapler to connect the grids together (if needed)
  • Stone infill
  • Washed and dried decorative stone
  • Gravel-Lok

Why do I need to use a non-woven geotextile fabric?

Not only does the fabric work as a weed barrier, its main purpose is to keep the infill stones inside the cells from migrating further down into the earth.

Do not use the fabric if the top surface will be grass or planted. Use Triax geogrid instead which will allow the roots to grow.

Do I need to connect the grids together?

Yes, connecting the grids together will ensure a continous matrix of cells without any weak areas.

If your project is small, you can drill holes and use 1/4″ zip ties to connect each grid. If it’s a larger project, we offer either a wide mouth or pneumatic stapler to make the connections faster.

What is the lifespan of LSG Load Support Grid?

LSG is made from HDPE plastic which will take at least 100 years or more to break down and decompose. It will last a lifetime!

When do I need to use Rebar J-Hooks?

Rebar J-hooks are needed when the top surface will be loose gravel or grass. This ensures the grid is pinned down and secured to the earth. If J-hooks are not used, stones could undermine the grid lifting it up over time.

The J-hooks are not needed if using pavers or Gravel-Lok.

Where can I buy your products?

We have authorized dealers throughout the country. Please visit the dealer section of our page, enter your zip code and local dealers will appear.

If there are no dealers in your area, we can ship directly to you. Please give us a ring at the office. 410-721-4844 or email info@celltekdirect.com

I’m installing Load Support Grid in a grassy paving application, do I need a gravel base below the Load Support Grid?

No. Unlike other grassy paving systems on the market, our grid is an “all-in-one” system. You do not need to install a gravel base below our grid.

How can I keep the grid spread open until I fill it?

Use rebar stakes around the perimeter to keep the grid open before and during filling. Once filled, remove the stakes and re-use them.

If your application requires J-Hooks, you can use the J-Hooks in place of the stakes. Do not remove J-Hooks.
