If you need to lower the water table below an excavation, keep water out of foundations, pits, or tunnels, or just need to dry solid materials at your site, you’ll need a dewatering solution.

There are a lot of choices out there, from submersible dewatering pumps to towable diaphragm pumps, electric trash pumps and more.

The type you’ll need varies depending on how much liquid you need to move, and how fast, as well as factors like what the liquid is and how far you’ll need to lift it. Sludge and debris require different pumps than you’d need to move lighter materials like rainwater and wood debris.

So, how do you know you’re choosing the right one for your job?

Here are five things you need to consider when choosing a dewatering pump:

1. What’s in the Water You Need to Move?

Water almost never comes alone – almost always, your dewatering system will also need to move gravel, sand, mud, or even trash. The amount of sediment and other debris in the water you need to move determines the kind of pump you’ll need.

If you need to move heavy materials like gravel and mud…

You’ll need a pump that can handle solids. Trash pumps are usually centrifugal pumps that have a large

discharge opening to avoid clogs. Heavier solids may require a shredder.

Diaphragm trash pumps like the Wacker Neuson Diaphragm Trash Pump PDT2 come in gas and diesel-powered models and are often ideal for these situations.

If your site only has light materials like sand, rainwater, and wood…

A simpler electric dewatering pump can do the job of moving clear water and water with light sediment and natural debris. For example, BJM R Series submersible dewatering pumps work well to lift light debris.

2. How Much Water Do You Need to Move, and How Fast?

The size of your pump is also an important consideration for keeping your site and workers safe.

Undersized pumps run the risk of flooding your job site when they can’t keep up with demands.

As a general rule, the bigger the piping and the larger the motor, the more water you’ll be able to move, and the faster it will work, but more isn’t always better – if you oversize your pump, you can pump the site dry and burn out the motor.

Pumps running significantly outside their ideal flow levels also can cavitate, which wears seals and bearings.

Calculating the ideal flow rate, in gallons per minute, will help you find the right pump – for help with this, contact our expert technicians.

How far does the water need to go?

You’ll also need to keep in mind where the water is going. The vertical distance you have to move liquid affects which type of hosing or piping you’ll need.

If you’re pumping into a tank or up high, you’ll need to consider friction loss, which reduces the effectiveness of a pump. As the static head (or distance you need to lift liquid upwards) increases, so does the amount of pressure that you’ll need to keep up with the inflow.

3. Choose the Right Type of Pump: Centrifugal vs. Displacement Pumps

Most dewatering pumps use centrifugal force or displacement to move water.

Centrifugal Pumps

Centrifugal water pumps use rotation to move water into the pump and pressurize the discharge flow. On most construction sites, centrifugal water pumps are a tool of choice.

Standard, trash, and submersible models are all typically centrifugal pumps.

These pumps are highly versatile and work well to move all thin liquids quickly. They also need to be filled with the liquid before use to work well. Low flow can damage the impeller, as can solids.

Positive Displacement/Rotary Pumps

Positive displacement water pumps typically use a diaphragm which contracts to pull liquids into the pump. They typically are used for very dense, viscous liquids with a lot of solids.

Though they can produce high pressure and aren’t as vulnerable to low flow, they tend to be more expensive and slower than centrifugal pumps.

4. Gas vs. Electric Pumps

Dewatering typically occurs early on during a project; there likely won’t be a built-in power supply on site.

Dewatering pumps come in both gas/diesel fuel powered and electric options.

If you’ll need to dewater your site for an extended period of time, an electric pump you can hook up to a permanent power source is probably your best bet. Electric engines also need less maintenance and can be less expensive to run depending on current fuel prices.

If the power source will be temporary, a diesel-driven pump is probably a better choice.

5. Submersible vs. Self-Priming Pumps

The best pump choice for construction is usually a submersible pump. Submersible “incapsulated” pumps can be completely submerged in liquid and work to effectively remove both liquids and solids suspended in the liquid from your site.

“Self-priming” pumps are smaller and can be more portable and easier to use, but they also tend to leave dewatered solids in the pit and stall frequently. Especially as the distance, your suction hose has to travel increases, self-priming pumps quickly become more expensive and time-consuming than they’re worth.

How to Find the Right Submersible Water Pump

There are several important factors to consider when choosing a water pump:

• Type of liquid and how fast you need to move it
• Your power source – gas or diesel? How big is your generator?
• How far your liquid needs to be moved
• What type of pump will best suit your site’s needs

Trench rollers are particularly well suited for compacting cohesive soils under excavations, roads, and parking lots.

Compaction works by removing air pockets from the soil, and when you need to compact soil in tight spaces, trench rollers are the best tool for the job.

Trench rollers essentially punch the dirt and vibrate it, making it denser by shaking the particles into closer alignment. This process helps eliminate settling, cracking, and heaving when building driveways, sidewalks, floors, foundations, and walls.

Once soil is properly compressed, it holds a lot more weight. This is critical to prevent surprise “voids” in the soil which cause defects after a project concludes.

Here’s a quick guide to make sure you’re maximizing your investment, choosing the safest and most effective option, and getting the best trench roller for your project.

Things to Consider When Looking for a Vibratory Compactor

Trench Width

The key advantage of a trench compactor is its maneuverability in tight spots.

Depending on your project, you can choose between several widths to minimize the number of passes you need, while choosing a model small enough to maneuver easily, even through the narrow trenches you need to compact. Some models also have built-in sensors to let you know when you’ve achieved the density required for your project.

Safety

Trenches made in loose soil are often prone to collapse. In the past, when compactors had to be pushed manually through a site, this posed significant additional risk. Today, many options for trench rollers are remote-controlled from a distance effectively increasing site safety.

Most also offer built-in safety features such as an automatic shutoff when the trench roller senses that the operator is too close, or when another object collides with the roller.

For example, The Pro Group offers a built-in safety feature in its trench rollers which includes a prominently placed infrared receiving eye on top. This ensures that the remote-control contact is maintained permanently, even in trench shoring.

Compared to previous models, modern rollers also have enhanced stability over uneven terrain, improving their reliability.

Soil Type

Most rollers are either “sheepsfoot” rollers or smooth rollers. Deciding which is better for you depends on your project and the soil type.

If you are working in clay-heavy soil, or another cohesive substate, a sheepsfoot trench roller effectively mixes these layers together to achieve better compaction.

On the other hand, smooth rollers run over the layers without mixing them. They work best on granular materials like sand or gravel.

Pro Tool offers a wide range of compaction rollers suited to every task. You can check out our fleet of cutting-edge walk-behind rollers, trench rollers, and other vibratory rollers in various sizes and weights here.

We’re always glad to talk to our customers, though we know that replacing parts and repairing equipment aren’t usually your ideas of fun. For that reason, this article suggests ways to realize the maximum possible value from your equipment and tools. Guess what? When a tool or piece of equipment breaks, the culprits are often either Mother Nature or ourselves.

Mother Nature’s Messes

The most common environmental factors that affect a tool or piece of equipment are:

• Extreme temperature
• Direct sunlight
• Dirt, dust, and mud
• Water

Obviously, it’s important to not leave your tools near water and mud, but also consider the long-term damage of exposing a tool to direct sunlight, freezing temperatures, and dust-laden environments. Thankfully, high-quality tools are designed to withstand the occasional splash of water and other elements. It’s the consistent negligence of a tool or equipment that can cause damage.

High-Quality Material Means Durability

Speaking of high-quality tools, when it’s time to purchase one, spend as much as you can afford. Although it’s natural to want to save money, don’t do so at the expense of quality. In general, the tools and equipment that are more expensive are that way because they are made with:

• Long-lasting materials
• Better design
• Sturdier housing

For example, a tool with tougher housing can better resist the invasion of dust or moisture that will damage the moving parts inside. A better-designed tool is less likely to have its internal components damaged if it’s dropped.

What You Don’t Know Can Hurt Your Tools

Construction equipment and tools can also suffer damage at the hands of untrained or negligent operators. For example:

• Using a tool at maximum power for an extended period of time can wear it out prematurely
• Using tools or equipment in ways they weren’t designed to handle
• Using incompatible accessories

It’s important to read the operation manual when you purchase a piece of equipment or a tool. It contains crucial information about:

• Calibration
• Maintenance
• Safety warnings
• Troubleshooting

If you’re unsure of anything, request a demo with one of our experts.

Tips to Extend Tool Life

Hanging on to your tools for a long time can seem like a losing battle against Father Time and Mother Nature. However, your ammunition is to be proactive in cleaning, maintenance, and storage.

Regular Maintenance

Get in the habit of starting the workday with a daily checklist of your machinery. This can help you spot worn-out parts. You’ll have time to get the part replaced, saving you from unexpected breakdowns.

Other maintenance routines include:

• Servicing and calibrating tools and equipment on schedule
• Maintaining fluid and oil levels
• Greasing parts
• Cleaning away dust, dirt, and mud
• Replacing fuel filters, chains, and belts

Pay Attention

Working at a fast pace can be the enemy of your tools and equipment because you might not notice what’s right in front of you:

• Noise—If you hear any strange noises, like grinding, popping, or whining, stop using the machine and get it checked out immediately. Make sure employees know to report unusual noise or behavior of equipment.
• Wear and Tear—Replace worn-out drill bits and saw blades. Using them causes the tool to work harder, wearing it out sooner.
• Heat—When you’re working with a tool, feel the battery pack frequently. If it’s hot, stop using the tool and let it cool down. This also applies to the gear box of any machine you’re operating.

Before leaving the worksite for the day, make sure all tools are stored away or at least covered up to protect them from dust and dirt. If possible, keep tools and equipment in a temperature-controlled area.

If you work in the construction industry, you already know that residential air compressor and air tools aren’t going to cut it. The demands of your job require something that’s durable and dependable.

This article covers the basics of a specific type of air compressor – the portable industrial air compressor. This type of compressor is permanently attached to a trailer that can be towed by a pickup truck and powers multiple industrial air tools.

Using a Portable Industrial Air Compressor

On a construction jobsite with limited access to an electrical power source, it’s quite common to find a portable industrial air compressor that runs on diesel fuel. This section provides the general steps for running a portable diesel air compressor; for specifics, check with a Pro Group expert or request a demo.

Safety Gear

• Besides wearing goggles and closed-toe shoes, you should also wear ear muffs for protection from the noise of the diesel motor and air tool.
• Place wheel chocks behind the portable air compressor’s wheels to prevent it from rolling during operation.

Maintenance Check

1. Check the level of all fluids:
   • Compressor oil
   • Coolant
   • Engine oil
   • Fuel level
2. Check the inside of the compressor for debris, loose connections, and the position of safety covers and guards.

Running the Air Compressor

1. Turn the battery switch on.
2. Open the release valve.
3. Start the diesel motor.
4. Close the release valve.
5. Turn on the compressor and wait for the air tank to fill up. When the air pressure gauge indicator stops moving, the air in the tank is fully pressurized.
6. Attach the tool hose to the regulator valve.
7. Connect the air tool to the hose.
8. Adjust the air compressor regulator to match the tool’s pressure.

Tips:

• While running the air compressor, monitor the pressure gauges. The air pressure must remain below the maximum pressure allowed for the air tool.
• If you switch tools, you might need to adjust the pressure again.
• When you are finished, release the drain valve.

Standard Industrial Air Tools

The portable industrial air compressor can provide power to the following types of industrial air tools:

• Chipping Hammers—You can use the multipurpose chipping hammer for light chipping or heavy cutting.
• Paving Breakers—Performing the same vertical demolition as a jackhammer, a paving breaker can be found in a variety of sizes that make it suitable for small jobs all the way up to heavy duty concrete demolition.
• Rivet Busters—Originally used for cutting and forming metal rivets, the rivet buster is relatively light, but has the same power as a heavier jackhammer. You can use it for vertical, horizontal, and overhead work.
• Rock Drills—You can use a rock drill to drill vertically in concrete or underground in bench mining. It’s also used for drilling blast holes and quarry work.
• Rotary Drills—Another versatile tool, the rotary drill can be used vertically or horizontally to drill holes in brick, rock, and other masonry. You can also use it to chip, scarify, and clean welds.

The Many Advantages of Industrial Air Tools

Compared to an electrical tool, industrial air tools last longer. They don’t generate heat while running, which is more comfortable for the operator. The lighter weight of the air tool also lessens operator fatigue and risk of long-term injury.

There’s a safety advantage as well. If an air hose springs a leak, no contaminants are released, as happens with hydraulic systems. Also, air tools do not pose a risk of fire or electrical shocks.

Versatile and rugged, loaders are construction site workhorses. Their adaptability and a long line of compatible attachments make a skid steer or compact track loader indispensable for many jobs.

While both wheel-driven skid loaders and their track-driven counterparts can be used in a variety of applications and work environments throughout the year, each has distinct advantages under certain conditions.

Skid Steer Advantages

If you’re buying rather than renting, a skid steer produces its first benefit even before it’s delivered, checking in with a sticker price that is often 30 percent or so lower than a track loader of similar capacity. Tires are cheaper to replace than tracks, so ongoing operating costs can be less of a hit as well, especially when working on hard surfaces. Asphalt and concrete are kinder to tires than they are to tracks, so if most of a company’s jobs involve working on hard surfaces, a skid steer may be the better option.

Consider choosing a skid steer rental or purchase under these conditions:

• Confined Work Spaces – Wheels allow skid steers to make tight turns. They can “pirouette” or pivot on one wheel, dragging – that is skidding, hence the name – the real wheels through a 0-degree turn radius. When walls, drop-offs, or other space confinements prevail, this turn-on-a-dime capability can make all the difference.
• Speed – In addition to making faster and shorter turns, skid steers also hit top working speeds of 10 to 14 miles per hour. This is about 40 percent faster than comparable track loaders. A few additional miles per hour may not sound like much, but it adds up, and the faster the job gets done, the more quickly you can move onto the next project.
• Portability – Because they don’t require the understructure on which track loaders rely, skid steers are lighter. They can be easily loaded and transported from site to site.

Track Loader Advantages

A skid steer likely is the best choice when surface and weather conditions are ideal, but when the going gets tough, a track loader could be the better option. They are best when tackling muddy, rocky, and slippery jobsites. Their tracks creating several benefits when working surfaces are challenging:

• Weight Distribution – Though their undercarriage components make track loaders heavier than comparable skid steers, the entire bottom of each track comes into contact with the ground. This greater surface contact spreads out the weight, so the machines do not become bogged down in mud or sink in snow. Tracks also tread more lightly than tires, causing less damage to landscaping and less time required for site maintenance.
• Accessibility and Maneuverability – Better traction on mud, sand, and ice allows track loaders to operate where their wheeled counterparts cannot. They may be able to recommence work immediately after a downpour, when drier conditions would be needed in order to bring in wheeled loaders. Greater productivity and shorter completion times equal greater profits.
• Track Life – While it is true that tires are cheaper than tracks, tracks offer significantly more operating hours than tires. They cost a bit more to replace, but you don’t have to replace them nearly as often if working on softer surfaces.

Snow Removal

With winter in full swing, loaders can be adapted for use in plowing or blowing snow. As is often the case, the jury is still out on whether tracks or skids are best suited for the job. Greater tractive power may allow a track loader to push and clear larger loads on level surfaces.

However, a wheeled skid steer’s heavier ground bearing will prevent slipping when plowing on inclines. The higher per-square-inch weight on the tires also bears on the blade, creating superior scraping power for one-pass snow removal.
