Save Your Sand With - SandMat & Super SandMat

Making a Sandy Beach? Build it to Last

The SandMat is a great solution for lakefront owners to create a beautiful sandy beach area between their grass and the deeper parts of the lake. It works by killing all lake weeds and preventing them from growing through the sand, and it prevents the sand from sinking and mixing with the dark soil of the lake front swimming area. It creates a barrier between the lake bottom and your sand. So just install the SandMats in the area where you want to place your sand and then dump the sand over it. Easy. The material is DNR-approved, lasts virtually forever, and is gas-permeable, (plastic tarps don’t work well, they trap gasses underneath, bubble up and sand slides off easily). It will greatly reduce the number of sandbags needed to create the sand beach area too. And for your ease of mind, we guarantee our SandMats for five years against defects in materials and workmanship.

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.

The sandmat allows you to make sandcastles on a lakefront property.
A sand beach is a great addition to your lake. Do it right the first time.

Hold your sand in place and suppress weed growth

The sandmat creates a sandy play area between the lakefront water and the weeds and muck that lie on the lakefront shore.
Putting a border between your lawn and sand creates a barrier that slows erosion from rain and snow runoff.

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.

SandMat or Super SandMat

What's the difference?

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.

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

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.

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

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).

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

Super Sandmat & SandMat FAQs

Absolutely! They provide habitat and protection for fish and waterfowl, they’re a food source, they recycle oxygen and carbon dioxide, they help prevent shoreline erosion and filter water particles. They become a problem when there is an overgrowth of aquatic weeds, especially on your beach front.
Yes, I leave mine in all year. You can take them out if you want to, but it's a lot of work and completely unnecessary.
Yes, but lily pads are a tough customer. The best thing to do is cut them back and put one of our Mats over them as early in the season as possible. If they're on shore, you can use a black, plastic tarp to place over them. The idea is the deprive them of sunlight. But they are tenacious!
I would. The thing about muck is, it releases a lot of gases in the summer and it moves around easily. The more tension you create over the top of it, the better off you are. Some people don't use all the plastic stakes, but for best results, I'd use them all.
It depends on what country, or state you're in, and sometimes, even what county or water body! If you speak with your regulatory agency, you'll want to tell them you're interested in installing a "seasonal benthic barrier." Most areas won't require a permit if it's something you put in and take out like a swim raft. If you're getting a MuckMat or BoatLift-Mat, it's primary purpose is to provide a "seasonal" platform to walk on. Most areas have no policy on lake bottom platforms.
It depends. If you have a lot of foot traffic, (boats, kids and dogs) that will keep sediment from building up. However, once a year or so (depending on how much sediment is floating in the water) you’ll want to sweep it off, blow it off, or if you’re really ambitious, take it out of the lake and wash it off. I don't suggest this last method, but it’s up to you.
Zebra mussels like structure, like your dock, your boat, or you if you stand still long enough. Our Mats are flat, like the bottom and aren't really attractive to zebra mussels. They move across the Mats, but don't stay there. They'll be about as scarce on our Mats as they are on open, sandy areas.
The only simple answer is use either a LakeMat Pro or a MuckMat Pro. The frame will keep it square and cause it to sink. I'd also suggest fastening some type of weights on the four corners to hold it in place until it settles on the bottom... yes, I'd leave the weights on it even after it settles.
No. That said, if someone is dumb enough to be fishing in shallow, weedy water, with a non-weedless hook, and they're dumber still to let it sink to the bottom and the hook gets stuck in the Mat, they will break their line trying to get it out. Doesn't happen often. At my current cottage, I've had eight Mats in for four years. Over that time I've had one lure caught on one Mat. Just pull backwards, and the lure comes out easily. If you have a bumper crop of dumb fishers, you may have more lures to pull out, but it's not likely.
Yes, it's especially easy to connect LakeMat and MuckMat simply by fastening the frames to each other. We had one guy who did 16 Mats! It's common for people to fasten two, three, and four together.
LakeMat and MuckMat will sink by themselves fairly quickly. It may take a few minutes. You can help it along if you wish.
