Everything You Need to Know about Cattle Grids

Everything You Need to Know about Cattle Grids 

Owning livestock can definitely be a challenge. Especially when your cattle get out into the road trying to cause trouble. You likely already have an understanding of a cattle grid sometimes referred to as a stock grid, if you’ve made your way to this post. But let’s dig a little deeper into the details of what cattle grids do and what’s going to be the best solution for your wandering livestock problems.

What is a Cattle Grid?

So, what are cattle grids for? They are often used as an alternative to cattle gates or fencing, the typical cattle grid design is a large pit in the ground housing a ground level concrete or steel grid for vehicles to cross over, but your livestock will struggle manoeuvring the gaps. 

The goal is to prevent cattle moving from one section of land to another where they aren’t wanted. You will normally find cattle grids installed at the external fence line which separates private property and public road systems, or potentially two sections of land on private property. After all, your livestock is a strong source of revenue; you’d hate for them to go missing!

Like most products, there’s a variety of designs available and it’s important to make sure you’re installing the cattle grid that’s right for you.

Common Cattle Grid Designs

Flat Box Cattle Grid 

The most common cattle grid installed is a flat box design. This design consists of three components which we will discuss below.

The grid itself, often referred to as piping, is the first and most important component of a stock grid. These can come in a variety of designs, but all maintain that original goal of keeping livestock where you want them. 

Both concrete and steel grids have the option of being produced with either a round of flat top, however both with still create an illusion of a deep pit that will deter your animals. The differences between round top and flat top grids are that the round top creates uncomfortable footing for cattle, sheep and alike. The flat top design will provide a smoother drive when travelling over the grid in a vehicle.

Most cattle grids will have removable boxes inserted under the grid. These are to remove any debris that makes its way through.

Lastly, your cattle grid should have guard wings or fencing along either side. This will prevent your livestock from manoeuvring around the side of the grid. Some cattle grids will come with these installed, but there is also the option to build a fence after your installation.

Boxed Cattle Grid

The other option is a boxed cattle grid. Retaining key features from a flat box design, the boxed cattle grid is installed above ground level and has a steel skirt installed minimizing debris entering the pit. As the grid is above ground this means your install will also be a little different. A bank of dirt will need to be created on either side to move freely across the cattle grid.

The boxed cattle grid design will likely move over time, and it is recommended these are installed for short term use.

What Materials are Used for Cattle Grids? 

Concrete Cattle Grids

Concrete cattle grids are one of the most popular designs on the market. Typically reinforced with steel rods, they are weather resistant and are strong enough for your heavy-duty farm equipment, such as tractors, to travel over. 

Steel Cattle Grids

As an alternative, galvanised steel stock grids are also available. These grids are often more affordable to transport and will provide the same strength as a concrete grid. However, steel grids are typically more expensive to purchase and may have challenges with weather conditions.

Virtual Cattle Grids

Virtual cattle grids have stemmed from some “out of the box” thinking entirely. By painting alternating light and dark colours on the ground this creates the illusion of depth. Although virtual grids have been shown to work, once one of your cattle works out the trick, the rest will be sure to follow. The cost to maintain the illusion over time will likely outweigh the cost of installing a concrete or steel grid as well.

Cattle Grid Drainage 

It is important to ensure your cattle grid can drain any rainwater that will enter the pit. Installing pipes or adequate drainage holes will prevent a build-up of rainfall. Excessive moisture can lead to a build-up of debris which can be challenging to remove, or even unwanted plant growth within the grid. As previously mentioned, removable boxes within your installation will also assist with build-up under your cattle grid.

Cattle Grid Sizes 

Whether it’s a public double lane road or a private walking track, cattle grids are available in a wide variety of sizes. There will almost always be a product to suit your needs, custom designs are also available if that’s what your project needs.

Types of Concrete Reinforcement in Australia

Types of Concrete Reinforcement in Australia

What is Reinforced Concrete?

It’s one of the most popular building materials you will ever come across, used for everything from residential house slabs to walls, beams, columns and some truly exceptional architectural masterpieces. You’ve probably heard the term a lot, but what does “reinforced concrete” actually mean? Let’s get into the nitty gritty, so we can better understand the types of reinforced concrete, and where each is best used.

Steel Reinforced Concrete

Steel is the most commonly used type of reinforcement for precast concrete products on the market today. When exposed to hot and cold conditions, steel and concrete react extremely similarly, expanding and contracting to a similar degree. This fact, along with its extremely high tensile strength, steel – in the form of rebar, wire, mesh or cables – is often used to reinforce concrete products used for structural purposes and in situations where an extremely high level of strength and durability is required. Steel-Reinforced Concrete Products are heavy, but extremely strong, able to withstand the multitude of temperatures and conditions that the harsh Australian climate can throw at it. A large range of Civilmart products are reinforced with the highest quality steel, including our Reinforced Concrete Pipes.

Glass Reinforced Concrete

Glass Reinforced Concrete (GRC) is a technique in which glass fibres are added to the cement mix, in order to provide a lightweight yet strong final product. The nature of GRC mixes allows it to be poured quite thin, further reducing weight and ensuring installation of products are fast, easy and cheap. Glass Reinforced Concrete is known for its exceptional flexural strength, and can be used to create complex shapes without the fear of chipping or cracking. Civilmart stock a wide range of lightweight GRC pits, for use in various applications.

Fibres Used in Concrete Reinforcement

In addition to glass, there are several other fibres that can be used to reinforce concrete products. In fact, the practice has been around for millennia, as prehistoric builders used to mix fibres such as straw and horsehair into their early cement mixes in order to add strength to their structures. While that practice may be more than a little outdated, there are a variety of fibre reinforcements in use today.

Synthetic Fibre Reinforcement

Synthetic fibres are made from synthesised polymers of small molecules, and are used in concrete mixes primarily to counter the development of shrinkage cracks. Several different chemicals can be used to create synthetic fibres, but the most common are petroleum-based chemicals. Synthetic fibres can be more cost-effective than steel reinforcement, but don’t offer the same kind of strength and durability. In cases where high levels of strength is not required however, synthetic fibre reinforced concrete is beneficial to creating smooth, long-lasting surfaces that aren’t prone to cracking.

Carbon Fibre Reinforcement

Carbon fibre is known for its high strength and minuscule weight. Recently, carbon fibre has been adopted for use in creating Precast Concrete Products, to considerable success. Lighter than steel but strength on par, carbon fibre reinforcement is becoming a hot topic in the precast concrete industry. It’s still largely untested, but it’s ability to be used as rebar and mesh have meant that carbon fibre reinforcement is becoming an increasingly attractive option for high-strength uses.

Plastic Fibre Reinforcement

Used mainly as a secondary type of reinforcement, plastic fibre reinforced concrete – like synthetic fibres – is extremely useful in reducing shrinkage cracks and micro cracking. Reinforcing concrete products with plastic is relatively cheap and easy, and is often added to mixes on site more commonly than it is used in precast manufacturing.

Benefits & Disadvantages of Fibre Reinforced Concrete

Generally speaking, fibre reinforced concrete products are lighter and cheaper than their steel-reinforced counterparts. This means that they’re easier to manoeuvre and install, with many of our GRC Pits able to be picked up and moved by two people, without the need of a hoist or crane. 

With its lightweight nature though, comes a lack in strength. Steel reinforced concrete is still far and away the most trusted form of reinforced concrete for heavy duty uses, and is often – when factoring in the lifespan of the product – the most cost-effective solution for these larger projects.

The Ultimate Guide to Reinforced Concrete Pipes

The Ultimate Guide To Reinforced Concrete Pipes

Reinforced Concrete Pipes are one of our most popular products. Used primarily for stormwater drainage, Reinforced Concrete Pipes are a key building block in almost any subdivision, roadway or major infrastructure project. Before ordering, it’s important to understand different pipe types, sizes and configurations, to ensure you get the right product for the right job. As one of our most popular products, we are tried and true experts in Reinforced Concrete Pipe. Let us share our knowledge with you in this ultimate guide to Reinforced Concrete Pipes!

What is a Reinforced Concrete Pipe (RCP)?

A Reinforced Concrete Pipe (RCP) is a type of piping made from precast concrete, reinforced with steel rebar for added strength and durability. Available in an array of sizes, ranging from 300mm to 2100mm in diameter, Reinforced Concrete Pipes are used to direct the flow of stormwater runoff (and other liquids) beneath the surface of the earth. Most commonly used as in stormwater or sewer settings, RCP can also be used for large-scale irrigation projects, as culverts or in a range of other pipeline projects.

Why Reinforced Concrete Pipes?

Reinforced Concrete Pipe is the most common and most trusted product for pipelines and water transportation projects. It has been used for centuries in this role, alternatives have sprung up more recently that have caused some debate over which product is best.

High-Density Polyethylene (HDPE) pipes are made from high-grade, strength-tested plastic material and has been used in stormwater settings in recent times. HDPE pipes are considered to be a low-cost alternative to RCP given their price point at purchase. Given the additional costs involved in on-site installation however, including structural integrity tests, engineered backfill, on-site inspections and post-installation laser testing, total cost for HDPE pipes quickly adds up. 

In addition to price, Reinforced Concrete Pipe has been trusted for centuries and has a proven 100-year lifespan. This reduces the need for infrastructure rehabilitation projects, further reducing the ongoing costs of choosing RCP. HDPE pipe is a much more recent product that simply does not have the raw data available to guarantee lifespan claims.

RCP Joint Configurations

There are three main types of joint configurations for reinforced concrete pipe; Flush Joint, Spigot-to-Spigot and Rubber Ring Joint. Typically, Flush Joint pipes are used for heavy-duty stormwater applications, Rubber Ring Joints are used for irrigation, and Spigot-to-Spigot pipes are used at the end of pipelines, to be installed into a precast concrete headwall.

Precast Concrete Classifications

Reinforced Concrete Pipe can be offered in a variety of “classes”. When discussing precast concrete, “class” refers to the finish of the concrete. Class 1 concrete is highest standard with the most rigorous specification and is only recommended for use in very special features of buildings of a monumental nature. When it comes to underground piping, where visual quality is unimportant, Class 1 finish is not required and is generally not offered.

Civilmart offer Reinforced Concrete Pipe in Classes 2, 3 & 4. This allows customers the choice and flexibility of having lower class finishes on purely underground piping, while having higher class finishes on piping that is above-ground or in general view.

Why Choose Civilmart?

Civilmart have been creating reinforced concrete pipe for over 70 years. That’s 70 years of experience creating some of Australia’s highest-quality precast concrete, helping to build Australia as it is today.
