Truck Tarps: Types, Benefits and Applications

Tarpaulins, or tarps as they are often called, are used in a wide variety of settings and industry. In the agricultural industry for instance, you can see tarps being used as covers for grain bunkers or livestock shelter. In the industrial sector, it is pretty common to see tarps being used as wall dividers or to cover items while in storage. In trucking and logistics, tarps are mostly used to cover the items being transported while on the road.

Covering truck beds and the items on them is just one of the many uses of tarps. They are used to cover the load on the truck, thereby protecting it from rain, sun, or snow and at the same time help to secure the load and keep them from falling off the truck bed. Sure, there are box vans or box trucks available, but there are certain items that only flatbed trucks are capable of transporting (e.g. lumber, construction materials, etc.) And when it comes to protecting the load on a flatbed truck, truckers generally rely on a good quality truck tarp.

Like many other items made from tarpaulins like factory dividers, bunker tarps, shelter cover and others truck tarps also come in different variants. More often than not, these classifications are based on the material the tarp is made from or the specific type of load it protects. However, most truckers generally classify tarps according to the following types: lumber tarps, steel tarps, and mesh tarps and each brings with it a certain versatility and suitability for hauling a specific type of cargo.

Type of Truck Tarps: Lumber Tarps

As the name suggests, lumber tarps are used by truckers who are involved in transporting lumber. They are generally made of heavy-duty material like Polyvinyl Chloride (PVC) or Polyethylene (PE), which are pretty much the same materials used in making other tarpaulin products like dam liners, temporary storage structures, and others. Obviously, these types of truck tarps are used to protect lumber from outdoor elements during transport; however, they can also be used for bulky and high-rising loads, and cargo that needs plenty of overhang.

Lumber tarps are designed quite differently from other types of truck tarps. In general, they are shaped and sized in such a way that that they are able to accommodate loads which can rise as high as eight feet above the truck bed.  Lumber tarps are usually sold in sets of two or three pieces, though they can also be bought individually. Lumber tarps, like other tarpaulin products (e.g. livestock shade structures, factory dividers, etc.) can also be custom-made, which is a perfect solution for truckers who have specific requirements and needs.

As mentioned earlier, lumber tarps can be made from different materials. Regardless of which material you choose, be sure to go for materials that are durable but not overly heavy. The weight of the material is an important factor to consider as the tarpaulin must be applied and tied down manually, and a heavy tarp is more challenging and more time-consuming to work with.

Type of Truck Tarps: Steel Tarps

As can be gleaned from its name, steel tarps are specifically made to cover steel products like pipes, cables, sheets, and others. Their design and the waterproof materials used in constructing the tarp should offer excellent performance when it comes to keeping the load dry and free from corrosion and rust. Most tarps used in hay sheds and temporary warehousing also have waterproof features as it is a necessity in keeping the bales of hay dry.

Like lumber tarps, steel tarps are also made from heavy-duty materials but are designed rather differently. One difference that you’ll immediately notice is that a steel tarp tends to be same in length as a lumber tarp but smaller in width. This is mainly because steel tarps are only intended to cover shorter and low-profile loads (loads that do not rise too high from the surface of the flatbed). A typical steel tarp is four-sided without flaps, have grommets and D-rings built in, and are generally secured with bungee straps.

Types of Truck Tarps: Mesh Tarps

One of the most commonly used truck tarps are heavy-duty mesh tarpaulins and are mostly seen on dump trucks and dump truck trailers. Unlike lumber tarps and steel tarps, mesh tarps aren’t made of solid materials, which means that they won’t be able to protect your cargo when it rains while you’re on the road. That said, mesh tarps are only used for covering cargo that isn’t damaged by moisture such as small rocks, gravel and sand. Aside from not being waterproof, truckers also have other issues with mesh tarps. For instance, mesh tarps tend to get snagged on debris such as nails or any protruding object in the truck.

Despite those issues, many truckers still use these types of truck tarps. They are lightweight which makes them easier to deploy and collect, durable, and available in a wide variety of colors. The holes in the mesh tarp also allows from ‘breathability’ which makes mesh tarps perfect for other applications like poultry curtains (although it can be rather challenging to find such a curtain in stores that sell poultry supplies in Australia).

Factors That Will Help You Decide Before Using Dam Liners

Dam liners are the most trustworthy method used in the prevention of water seepage and potential leaks in dams. If this is your first time using dam liners, here are a few factors to help decide wisely.

  • Material component of dam liners

Most of the dam liners sold in the market are made from a heavy-duty plastic material that has a rot resistant feature. What does this mean? The plastic component can withstand submersion in water and will not decay.  Dams lined with PE and rubber based lining materials have a service life of approximately 40 years or more, however, the integrity of dam liners can be decreased due to degradation brought by harmful rays of the sun with possible damage (poor preparation of surfaces or wear and tear).

  • Service life of dam liners

Dam liners can provide long years of service if proper installation is carried out. PE liners made from high-grade material are expected to last at least 10 years, but can be exposed to deterioration from UV rays. If you want to decrease UV exposure, better cover dam liners with soil of at least 300 mm. This common practice has been proven to extend the serviceable life of the liners. Another way to protect dam liners from possible damage is by installing a fence around the dam or cover with soil, especially if animals have a tendency to walk on these liners. Don’t forget to remove rocks, roots and other sharp objects that are lying underneath the surfaces of dam liners. If you cannot prevent these hazards from causing tears or holes, then, put underlay material like geotextile.

  • Material cost of dam liners

The material cost of dam liners is another important factor to consider. Careful assessment on how much liner material is needed for edging and trench on both sides. You may also take into account the slope of the dam walls. Why? Well, the deeper the dam, expect the dam walls to be a lot steeper and the edging to be wider. So, this simply means you need enough funding to proceed with the installation of dam liners.

  • Edging requirement

Edging is crucial in the installation of dam liners. In most cases, the amount of edging to be done will be based on the design of the dam. However, the standard edging required is at least 1 metre of extra liner around the area. If unsure of the ideal edging, consult an expert in dam design and installation.

  • Types of liner materials

The materials that can be used for dam liners do vary. Depending on one’s preference on design, method of application and allocated budget the common types of liner materials include polyethylene (PE) or Polypropylene (PP). Other materials used for dam liners are EDM and butyl-based rubber that has the longest service life of at least 30 to 40 years.

What To Consider When Building Farm Pond Using Dam Liners?

Are you building a farm pond using dam liners? You may think this project would only need digging a huge pit and filling it with water, but, there are other things that will help you get the desired outcome and here are some of them.

Purpose of the farm pond

Ask yourself this crucial question before you even start digging a farm pond and lining it with dam liners, “What is the purpose of this farm pond?” Is it intended to be a source of water supply for your farm animals? Or, perhaps you plan to fill it with fish and harvest them in a few months. Whatever answer you will derive will give you a clear estimate on how deep this farm pond should be. For example, if it is intended as a fishing pond, then the recommended depth is approximately 6 to 8 feet. However, if the pond will be used as a water source for your animals and other livestock, then, make it steep on sides to allow them to drink safely even when the water level dropped.

Surrounding watershed

When building a farm pond the surrounding watershed plays an integral part of the planning of design and size. Carefully inspect the surrounding watershed situated in your land area and find out where the source of water is coming from. For your peace of mind that the farm pond you will build and lined with dam liners will have a continuous supply of fresh water is locate the specific location of a watershed that could drain off water into your pond.

Type of dirt that you will dig

When starting a farm fond, expect a lot of digging. Of course, it would be helpful if you know the type of soil you will be digging into. For example, the best type of soil is clay-based to ensure water is preserved for longer periods. You also need to make sure that the dam liners you will place are durable enough to prevent future leakage. If not sure on what type of dam lining material would best fit the type of soil in the area where you build a pong, don’t hesitate to ask the experts.

Presence of pollution

Pollution can cause contamination to your farm pond. When building a farm pond keep distance to anything that will lead to chemical or oil spill. Remember, these harmful pollutants can contaminate the water source of your pond and be harmful to your animals or fish. So, the rule of thumb for first-timers planning to build farm ponds using dam liners, stay away from areas where high levels of pollution or toxins exist.

Weather condition

Yes, definitely a major factor to consider before starting a farm pond project is the prevailing weather condition in your area, Is it always hot or humid. If so, expect the water inside the pond to evaporate quicker. However, this can be resolved by putting top quality dam liners that can hold as much of water supply.
