Getting from Point A to Point B quickly, safely and cost-effectively without damaging the underlying surface.
That’s SVE Portable Roadway Systems, Inc.
With our MUD-TRAKS® Series ; TRAKMAT® Series and emtek® Heavy Equipment Mats we offer a wide range of lightweight and heavy-duty mats that make it easy to get onto and off of difficult ground conditions as well as established lawns and landscapes. Mats come in numerous materials, sizes and thicknesses to handle applications from moving the lightest equipment over green grass and relatively flat terrain, to equipment up to 100,000 pounds over wet and challenging subsurfaces.
In addition to the mat system, we offer several complementary products that are used in conjunction with Portable Roadway Systems: Outrigger Pads, for trucks and cranes, Ditch Bridges, Trench Covers, Dozer Mats, Dirt Boards, Pole Jack Plates, and Cable Ramps. All of our products are Made In The U.S.A
GENERAL MAT INFORMATION
Load Bearing Capacity
To move heavy vehicles across wet ground or sand you have to answer the basic question of: “how much weight (in pounds per square inch or PSI for short) will the soil support?” The average workman does not usually have a way to directly measure the soil’s load bearing capacity. So here are some guidelines to help him determine what will work.
Let’s start with a frame of reference: A 200 lb. man with a size 10 shoe walking down a road is about 11 PSI. A pickup truck with an empty bed passing him is about 25 PSI. And a fully loaded tractor trailer, “road legal” by weight, going down the road is about 75 PSI.
*“Road Legal” means the tire weight meets the DOT standards for highway driving.
How a Mat Works:
MUD-TRAKS® are manufactured with continuous fiberglass strands that stiffen when tire load is driven over the mat until the tire load is spread over an area approximately 12 times larger than the footprint of the tire reducing the PSI of each tire. Please note*: in critical ground support situations, it doesn’t help to overload the vehicle.
The tough question is, “What if the ground won’t support a man walking without leaving a shoe imprint?” We should be able to help, but we need to know the vehicle weight per tire, and some measure of how soft the ground is. Go to Installation & Handling on this web site and open Using MUD-TRAKS Super Mats, paragraph 14 tells you how to make and use a “T” bar probe.

Plywood is designed primarily for use as exterior sheathing in the construction of homes. The lowest price ¾” plywood is now about $30 a sheet. It weighs about 67 lbs. dry and 118 lbs. soaking wet. It loses 30% of its strength when wet, and then it starts to dry rot. It has no traction surface, no rope handles, no hand cutouts, but it does have splinters. Plywood is no longer a cost effective, portable, roadbuilding material! Unless you truly have a one shot deal, a MUD-TRAK®; solution is the better value.
Our Mat Products
SVE’s mat products are designed to carry heavy loads, from 60 ton and more. In the Small Mat Series (mats weigh less than 100 lbs.): TRAKMAT®: a flexable mat that works best over lawns and ground areas that have the ability to support load. They are not intended for severe mud applications. MUD-TRAKS®: support extreme loads in near wetlands conditions. They can handle tire loads of any road legal vehicle in areas that, at least can support the weight of a man walking without leaving a foot mark. In the large Mat Series; emtek®Mats are defined by their size, and are set in place with machinery and used for large work areas, severe ground conditions, or where steel track equipment is required.. None of our mats are affected by water or insects. Their VALUE is years of service.
