Portable Footings
& Riser Support

When dealing with a swampy area that does not have high enough or stable enough banks, our portable footing and riser support is your answer.

The footing is made of 3/16" steel and hot dipped galvanized. The riser support holds the bridge up off the ground when you do not have sufficient bank height for the bridge to sit above the waterline . This portable footing and riser support is exclusively our invention and is patented.

With its flow-thru design, it minimizes the obstruction of the water flow and it will compensate for spring's wet conditions. A bridge approach is usually needed when a riser support is used. u.s Patent No 6,421,863
