Cattle Guard Foundations – Setting A Texas Gate

Installation

Cattle guards are an indispensable part of managing livestock. Their simplicity and ease of use, combined with their longevity, make them the ultimate Texas gate.

Cattle Guard Foundations

Although some have mounted cattle guards to railroad ties for support, the most permanent and recommended installation method begins with a concrete vault.  The vault serves two purposes:

  1. Keep the dirt from behind the walls of the vault area from creeping in
  2. Allow the footings to provide proper support

A concrete cattle guard foundation will ultimately be a thick, four-walled ‘box’ and is recommended to be poured after the arrival of the cattle guard. The depth of the walls is not a one-size-fits all measurement, but is determined by the local conditions such as drainage, soil type and freezing levels. It is important that a contractor who is familiar with the site conditions be consulted so that the foundation will provide a solid and stable base for the cattle guard to rest on.  The support beams do not rest on the vault walls, only on the footers to transfer the weight of the passing vehicles to the ground.

Generally, it is suggested a trench, about a foot deep and wider than the guard itself be dug. The cattle guard foundation walls should be at least six inches wide to make up the ‘vault box’ so that dirt will not collapse the walls and the footers should be large enough to support the passing vehicle weight and transfer the load to the ground.  We typically see 12 inch walls that are eighteen inches deep to support each load-bearing beam of the guard.

Depending upon your soil conditions, drainage may be achieved with a deep crushed-rock base such as a French drain or by running PVC piping through the concrete walls to discharge any excess water. Some areas may allow for natural drainage, but without proper removal of any water, the foundation and thus the guard itself may be compromised. Effective drainage is vital to the longevity of the crossing and should be done with the best possible long-term solution in mind.

Boxed Cattle Guard Installations

A boxed cattle guard is a great choice for temporary use in low traffic areas or construction sites. Laid directly on flat ground, they can be spiked into the soil, railroad ties or a set in a firm gravel mix to help eliminate movement. They are great for low volume access areas and don’t require a vault to be dug underneath. A steel skirt is welded directly to the frame and will help keep the area below clear from creeping dirt. Very popular with construction sites, the guards may be moved from location to location and be used as dirt shakers, or washout areas to clean equipment before leaving a job site.

Best used in situations where the cattle guard will be used temporarily, these versatile installations will do well for all types of applications.

Cattle Guards are the Ultimate Livestock Gate!

Cattle Guards are the ultimate invisible livestock gate

By Barn World Livestock – sales@barnworld.com

Cattle guards offer ease of access to your livestock pastures, farm and ranches while keeping your animals safe from wandering. The simple design allows vehicles to pass through a fence line holding most ranch animals without having to stop and open, then close a gate. If you have through traffic or other people working on your farm, you never have to worry about an open gate in the middle of the night.

Take a look at some of the more common options to find the fit that’s right for your crossing.

Top Rail Options:

Barn World offers each of the cattle guard types below with either round pipe or flat pipe on top. The top pipe runs perpendicular to the direction of vehicular traffic and rests directly on the c-channel or i-beams underneath. The weight of the vehicle is transferred from the pipe, to the beams and then to the ground.

 

Flat Top Rails

is ideal for areas of high speed traffic such as public roadways and other crossings with a lot of traffic moving at a faster clip. The finish allows for a more smooth transition of the barrier with the least amount of ride disruption to the passengers and vehicle. They can commonly be seen in use by state & federal highway projects.

Round Top Rails

are of the same design as the flat pipe and come in 3-1/2 or 4-1/2 diameters.  The round pipe causes a bit more vibration on passing vehicles,  but is seen as a more effective deterrent to livestock.   The curvature of the pipe creates less of a balancing surface for hoofed animals creating more discomfort on the foot and leg if stepped on.  It is very difficult for hoofed animals (goats excepted) to get a secure footing feeling while balancing all of their weight on such a small, rounded surface.

The curved pipe also creates an optical barrier for livestock.  The curvature of the round pipe creates shadows that offer an optical barrier for the animals.

A study was done comparing the effectiveness of traditional round pipe cattle guards to white lines of roughly the same width painted on a black road surface to create the illusion of depth. The painted lines were found initially to be surprisingly more effective than first thought. When cattle were introduced to the markings, they we not interested in testing the barrier, but when they had had some time to inspect the painted surface, the eventually were able to overcome their initially hesitation and cross without effort.  Once they were able to determine the road was indeed flat, they did in fact cross easily. The optical illusion of a barrier did deter them for a time, but when there was a incentive to cross it, they did. The researchers found that they still preferred to go around the markings, but didn’t have a problem crossing once the ‘jig was up’.

Round Steel Rails are Effective

The traditional round top rail cattle guard, couples the optical deterrent with the physical to provide the most effective obstruction. Livestock that are motivate to attempt a crossing and are brave enough to place a hoof on the guard quickly discover that the footing is unbearably unstable and will usually withdraw their hoof.  After that initial uncomfortable encounter with the steel round pipe, they will typically avoid it at all costs.

We have had reports of some aggressive or spooked bulls attempt to jump over the obstacle.  This is usually done in times of panic and some of the larger more athletic bulls can jump six feet or more on occasion.  For these more muscular and nimble ‘jumpers’ and eight foot (in the direction of travel) cattle guard has proved to be more than enough to show the animal that it’s a barrier not to be contemplated.

Cattle Guards Don’t Work With All Animals

Of special note, even round topped guards do not work with all animals. Smaller hoofed farm and ranch livestock such as goats and some sheep can be very nimble and often have no trouble tip-toeing through. Animals with soft pads on their feet are able to balance on the round piping and although not a comfortable footing, they are able to walk across if they desire.

Vaulted vs Boxed Cattle Guards

A second option available in the selection of cattle guards is the boxed vs. the traditional vaulted that requires a footing to rest on. The boxed is designed to lay directly on the ground in low traffic areas without a concrete foundation.

 

The boxed cattle guard

Boxed guards have a steel skirt surrounding it. The skirt may be either welded into place or be removable.  The integral box is a steel skirt welded directly on that creates a barrier for dirt to creep underneath. With this type of box, installation may be made directly on the ground without the need of footings or digging. To clean out any debris that may have built up over time, it is simply drug out of place and then slid right back in.  At near 12 inches tall, dirt ramps are built up on either side to allow vehicles to cross over.

This type of installation is considered less permanent and is very popular in low traffic areas and construction sites needing an equipment washout area or a dirt rumble to clean vehicles before they enter a pubic roadway. They are also more ‘portable’ and may be move from job site to job site if necessary.

 

Cattle Guard Installation

is done with a concrete foundation (although other materials are also used; for example railroad ties) and a ‘vault’ area is dug underneath to collect debris. Typically, a rectangular concrete foundation is poured to keep the dirt walls from falling in and to provide support to the beams that run in the direction of traffic.  Although not considered a difficult endeavor, an experienced contractor who is familiar with the local soil conditions and frost / freeze levels is highly recommended. If not properly supported, changes to the soil during freezing, water saturation or runoff may affect the structural integrity of the crossing and the cattle guard itself.

ATV Cattle Guards

There is also a cattle guard specifically designed for ATV use in crossing fence-lines.  We’ve custom built these for golf carts passage as well. Simply cut whole in your fence-line and drop this guard into place. One you connect your fencing the vertical supports in the middle, you’re done. That’s all that’s needed!

Drive-over Gates

Another alternative to traditional cattle guards.  These gates pivot and allow the it to lay flat for a vehicle to safely cross over and then return to their upright position automatically.  This type of gate has been successfully used in busy feed lots with lots of tractor and truck traffic and provides yet another secure means of keeping livestock in place while allowing access to busy areas.

Cattle Guard Load Ratings

The American Association of State Highway Transportation Officials or AASHTO, supplies maximum load ratings necessary for highway bridges and all crossings that support traffic. The common load design specifications are shown in the table below:


Per Axle Load Ratings
H-15 (12 tons per axle)
H-20 (16 tons per axle)
U-54 (25 tons per axle)
U-80 (30 tons per axle)

 

These ratings are used by engineers who issue certificates of design reports and certify builders to ensure the product meets the load requirements for the ratings used above. To achieve the designation, manufacturers must use specific welding techniques, materials and designs before the guard can be certified and used in a public roadway.  For most highway crossings, the 16 ton per axle or H-20 rating is used.

 

Driveway Cattle Guards

When used on private property, the grids don’t require an engineer’s certification and are therefore more economical than the rated. Designed for use on private property, they can be made from the same materials and design specifications as the rated.

All cattle guards sold by Barn World are built to withstand fully loaded semi-trucks and large farm equipment. They are very popular with traditional farm and ranch operations.

Concrete Cattle Guards

Note that we do offer and alternative to steel: concrete cattle guards forms. These poly forms create a livestock barrier that won’t allow a hoof to slide down between steel rails. They taper together into a 2 inch base as shown below.
