Save Money on Concrete Hose Accessories

Concrete hoses

Concrete and plaster pumping equipment and hoses especially, get a lot of wear and tear over the course of many jobs. Replacing hoses can be expensive and is not always necessary. Did you know that you can have your used hoses repaired for a fraction of the price of a new one? This goes beyond the usual servicing, because needed parts are actually replaced and tested.

United Equipment Sales can save you money on your existing concrete equipment by having us do any of the following repairs:

 Install a new weld-on end (metal ring part) to convert your regular hose to a heavy duty hose out of it. We fill the grove with steel so it takes longer to wear it through. They come in different sizes from 5” to 1 1/2 “ to fit all your needs. There are different types: heavy-Duty, Metric, Grooved, Male/Female. Each one is machined on computer-controlled equipment from quality carbon steels.

Install a new clamp and snap couplings
Grooved, heavy-duty & metric, both non-adjustable and some adjustable sizes. All of our clamps have been redesigned with very “user-friendly” handles and come with gaskets and safety pins. They are also all steel construction (not ductile iron), for added strength and gold colored zinc coating or painted green.

Install a ferrule (metal end) When have a bad end, we cut off the hose behind the original ferule and replace it with a new stem and internally expand it into the ferule (which grabs the hose on both sides so that it can’t back up).   We can use a heavy duty or a threaded end. If you need an adaptor, we also manufacture our own with threaded end, with coupling. Size vary from 2 “ to 1 ½”.

Slabjacking accessories

You can also replace different sizes of shotcrete nozzles for shotcreting tunnels and swimming pools. They come in 2 sizes: 1 ½” to 2 ½” nozzles with tips. They can get really worn out after many jobs.

 
NOTE: a clean out ball should always be used after every job to make sure that you get 99,9% of the cement out of the hose. This will extend the life of your hose and equipment.

The good news is that we ship anywhere in the world. Most of the cases we can turn around your order in less than 3 days depending on the amount the work needed. Accessories can be shipped the same day.

How To Repair Broken Concrete

Cracked concrete

damaged concrete slab

If you live in a house that is over 50 years old, chances are you have cracked concrete somewhere on your property or a slab sinking. Whether the problem is in a foundation, a sunken sidewalk, a concrete patio surface, a damaged pool deck, concrete stairs, a parking lot or a factory floor, uneven and cracked concrete floors are not only unsightly and potentially dangerous but they also decrease property values and in some case can even result in safety hazards. The reason why so many people don’t ever address the problem is that the idea and the cost of pouring a brand new concrete pad can be too much for most property owners and especially in tough economic times. So what is one to do? Is there a lesser painful and costly alternative?

There is and it is called slabjacking, a.k.a mudjacking.  Considering that you can do a permanent foundation repair and re-level your floor for less than half the cost of pouring new concrete, this is great news. Wait, there is more, you are not only saving on cost, but you don’t have to pay for the usual demolition, removal and dumping. This means that not only you can repair the problem in record time (it can be done in one day because you don’t have to wait for the grout to cure), for about half the price and with a lot less disruption in the area (think costly damage to your landscape)!

How to repair damaged concrete slab:

Let’s say that you decided to mudjack your driveway. All you need to do is drill holes through the slab and pump a sand/cement mixture under the slab until it is filled. Complete the job by sealing up the holes with a cement mix to conceal them. Job done! Over time the strength of the repaired slab is similar to having poured a brand new concrete slab.

What equipment should I use?

Mudjacking equipment

For a big jobs you may need a full size trailer line pump.
For smaller jobs like smaller walk-ways and slabs, you may want a gas model machine with variable displacement (50-900psi).

The only green solution

Mudjacking is not only quicker, cheaper and faster it is also greener because not you are not wasting all the additives to do the job like fuel to operate equipment, manpower, waste removal & dumping of all the broken concrete. Mudjacking is a great affordable solution for everyone in need of durable and practical repair.

5 TIPS TO SAVE MONEY ON CONCRETE PUMPS

Putzmeister-TK303 concrete line pump

In difficult economic times, we all need to learn to do more with less. This often means extending the life of our equipment by treating it with a little extra TLC. Prevention is the key.

Here are a few tips everyone should follow to do just that with concrete pumps:

 1.      Grease your machine

Main parts: lubrication of pump’s pivot points
Frequency: approximately every 2 hours of use

Note: Failure to grease your pump could result in potential failure of bearings and bushings, breaking down of equipment on the job, loss of productivity, costly repairs…

2.      Check fluid levels

Minimum: hydraulic oil, engine oil & slosh box
Frequency: Daily before starting the job.
Since it only takes a minute, don’t skip this step. Start making it part of your job routine.

3. Clean the pump

Areas: Pump water through the pump and the hose simultaneously.
Frequency: End of job/daily

Note: This isn’t something you can postpone, depending on the temperatures, concrete can harden in the pump and hoses anywhere from 0-2hrs!

4. Hire an experienced operator

There are many advantages to have an experienced operator.
Here are a just a few:

a. Safety on the job:  Knowing how to quickly react to pumping problems is paramount. It can save lives.

b. Proper hose connection (many deadly accidents have happened because of this).

c. Overall inspection of pump and hoses prior to starting the job.

5. Follow the manual’s procedure

Take a moment to scan through the manual that came with your pump. Only dealers will provide you with a manual when purchasing a used pump (brokers don’t always do) so if you are serious about your work, contact a dealer first. They will stand by their products and will help you make a more educated decision.

4 Questions to ask when buying a used concrete pump

 

Used concrete pump Mayco ST-30

 

Whether you are a home owner looking to make some home improvements, a general/subcontractor or a concrete pumper, having good and reliable tools will make all the difference on the job, whether or not you can complete it in time and within the budget. So here are a few questions you should be asking when researching to buy a used concrete pump:

1. What is the pump capability for the job requirements?

a. What is the right volume/yard per hour (yph) you need
If you don’t get this right, the pump will operate too slowly.

b. What is the maximum aggregate size?
If you don’t get this right, you won’t be able to get the job done, you risk
incurring thousands of dollars in equipment repair, you could blow a hose
fitting, endanger your work crew and you could also damage nearby property!
So make sure you get this one right!

c.  What is the proper hose system?
If you don’t have the right hose diameter or length, you won’t be able to get
the job done. Too large aggregate could plug the hose and damage the pump.
If you don’t have the right hose length, you will delay the start of the project
having to locate and purchase the correct length hose. You get the idea…

2. What is the condition of the used pump?
This is by no means a perfect science since used pumps don’t come with
maintenance papers but you can get some idea of usage is left. The appearance
of the pump will provide some indication of previous maintenance work.
Parts wear out over time…

3. What is the age and the number of hours the pump has been used?
Depending on the number of jobs you have lined up, you will need to know this
before deciding the best brand/model for you.

4. Can I get a price comparison between a new and used concrete pump?
Based on your budget and the volume of jobs you anticipate, make sure to do the
math before you buy so that what you get will fit your future needs.

These are some of the most important questions you need to ask. They should
cover most of your bases and help make an educated decision based on important information.
