Lake Weed Control – Green & Guaranteed!

SandMat – makes a great base to start your beach

It takes work to make a sand beach on an inland lake. You want it to last as long as possible. To make your new beach last, you need a base to keep it separated from silty lake bottom soils. If you’re putting sand over muck – you definitely need a barrier to keep your sand from sinking.

SandMats & Super SandMats will do just that.


A sand beach is a great addition to your lake. Do it right the first time.

SandMat - say goodbye to muck

Putting a border between your lawn and sand creates a barrier that slows erosion from rain and snow runoff.

Hold your sand in place and suppress weed growth

Sand, on a mucky lake bottom, doesn’t last long. Your sand is heavy — it sinks quickly in the soft soil — because sand is heavier than silty muck.

Your sand may move with waves, drift in currents, shift with turbulence and ice movement. You need a good base to hold it in place. (Ever put sand in your beach and your neighbor ends up with it the following spring?)

SandMat keeps your sand from sinking, drifting, shifting and mixing with lake bottom muck.

SandMats and Super SandMats provide excellent support for your sand — gives you great “soil separation” and suppress weed growth — both in the water and on shore.

What SandMat gives you:

  • Excellent “separation” between your sand and lake bottom
  • Suppresses lake weed growth beneath your sand
  • Lasts for years, nearly forever
  • Use on shore and in your lake
  • Connect multiple SandMats for larger areas
  • No Chemicals, “Green” method of weed control
  • Get extra support — with Super SandMat
  • Prevents sand from sinking in deep muck (Super SandMat)
  • Made in Grand Rapids, Michigan, USA

SandMat or Super SandMat – What’s the Difference?


SandMats are best used as a base on shore, or from shore into shallow water.

SandMat – Creates a sandy beach – from shore to shallow water

SandMat is made for shorelines and firm lake bottoms. As a base for sand, it creates a “separation barrier,” keeping your sand from mixing with lake bottom silt.

SandMats control lake weed growth and hinder new lakes weeds from taking root, keeping your sandy beach weed free. They provide excellent soil separation and a good solid base.

Super SandMat

Pictured is the Super SandMat fabric and grid. You assemble them onshore and place them in your lake together.

Super SandMat – Creates a sandy beach – from shore to shallow water

Super SandMat is a “souped up” SandMat, providing extra support for mucky lake bottoms. It works like a giant snowshoe. Super SandMat adds a grid under a SandMat. This extra support keeps you and your sand out of the muck.

Super SandMat does everything a SandMat does — plus provides the additional base support for sand on soft, lake bottoms — near shore.

The grid lays on the lake bottom, the fabric lays on the grid — you place the sand on top of the fabric to create a firm base and provide excellent soil separation.

For deep water sanding in mucky soil — consider MuckMat Pro

SandMat and Super SandMat are held down ONLY by sand placed on top — They have no weights or frames. We provide plastic stakes to temporarily hold them in place — they do not stay down on their own — you must add sand. (Most people use 3 to 8 inches of sand or gravel).

If you think you may want something with a frame you can also sand to, especially in deeper water, (over 2 feet) over very soft muck — take a look at MuckMat Pro. You can put sand on a MuckMat Pro just same as a Super SandMat — and it’s easy to work with in deeper water because the frame holds it in place on the lake bottom while you put sand on it. A MuckMat Pro is a Super SandMat with a rigid aluminized, steel frame.

SandMat & Super SandMat – now you’re ready to make your beach

SandMat and Super SandMat are the best base and soil separation you can get. The material lasts virtually forever, it’s water and gas-permeable — so it rarely bubbles, (plastic tarps don’t work, they trap gasses, bubble up and your sand slides off).

You’re ready to make a beach on your lake — we know it’s a lot of hard work — be sure to make it last. 

SandMats & Super SandMats come with plastic stakes to help hold them in place on the lake bottom while sand is added.

Note: Natural resource agencies in some states require permits to introduce sand or into lakes. They may have limits on how much sand you can use. Some require you to remove the same amount of soil as you put in. We suggest you check local regulations.
