PumperDump is the Solution to Pollution | The Responsible Choice

Our previous blogs explored the importance of effective concrete washout management to prevent damage to the environment. Today, we’re going to take a closer look at both the environmental impact of concrete washout as well as what makes PumperDump the responsible choice for your construction projects. It goes without saying, concrete remains one of the most widely used substances in construction projects in the world. Undeniably, it’s one of the most commonly made materials on the planet, and the demand for concrete is astronomical. As the population increases and cities expand, the demand for concrete only increases. The prevalence for concrete is one thing, but it is not the whole story. It’s also the case that the materials which make up concrete can be quite hazardous. Is concrete washout really that bad for the environment? It’s reasonable to wonder if all the racket made over concrete washout is all that justified. After all, concrete structures can be found far and wide, and they don’t seem to be harming anything. Is this perhaps just a case of the NSW Environment Protection Authority (EPA) being overly-cautious and simply extending its reach beyond where it belongs? In short – NO. Concrete washout really is that harmful to the environment. Sure, concrete structures are everywhere. Once concrete dries, it becomes a stock-still substance that no longer poses a threat. Before that, the concrete mixture – and the water that was used in it (not excluding the water that was used to clean off the tools and trucks) – is corrosive. This material contains, grout, plaster, cement, mortar, stucco and other materials that contain harmful chemicals. The danger arises from these materials leaking into local water sources. As previously mentioned, concrete washout water has a toxicity level greater than ammonia and near the same pH level as chlorine bleach. It’s obvious as to why PumperDump tries so hard to prevent these substances from reaching our local water systems. What can we do about concrete washout? So now that it is evident that concrete washout is permissibly harmful to ecosystems, including our waterways. We’ve established that the regulations and precautions implemented by the NSW Environment Protection Authority (EPA) are not mere overreactions. What now? What can be done about concrete washout? Good news, there are several ways to approach concrete washout. An approach to concrete washout that used to be very popular was washout pits and washout bags. We’ve discussed before why these “solutions” are a thing of the past. There are many risks – both environmentally and financially – that come from choosing either washout pits or washout bags. We do not recommend it. You simply do not want to make use of inefficient washout systems. Doing so risks:
  • Contaminating lakes and other swimming areas with high amounts of zinc and iron, which have proven to cause diabetes, cancer, skin irritation and other adverse side effects
  • Exposing fresh waterway to corrosive, caustic concrete washout water and materials that may result in all kinds of damage to ecosystems
  • Allowing calcium, magnesium oxide, and calcium – conventional ingredients in ready-mix concrete – to infiltrate our soil systems
What’s the responsible option PumperDump offers alternatives to the inefficient washout systems. We have brought together innovative technology, patented concrete washout separation units and blowback units, a dedication to efficient and quality services, and a passion for ethical environmental practices to bring the industry the best concrete washout solutions. All in all, we understand the importance of needing to tackle construction projects affordably and efficiently, whilst also maintaining ethical environment practices. PumperDump is the responsible choice. We are your solution to washout pollution.

Introducing PumperDump’s New 5m3 Patent Pending Blowback Bin

Transforming industry experience, a wealth of knowledge and continuous system innovation for concrete pumping and concrete waste collection, PumperDump has been a player in the concrete pumping industry for years.

With the roaring success of the 2m3 (2 Cubic Meter) blowback bin which launched more than 10 years ago, it was not difficult to notice the gap in the market for something a little bigger. After months of planning and trialling, we are proud to introduce the new 5m3 (5 Cubic Meter) blowback bin to the streets of Sydney. 

Our latest innovation would not be possible without the collaboration of some important players in the industry.

We would like to thank Bincorp for the manufacturing of the bin, De Martin & Gasparini for assisting during the construction and for trialling the bin, and WATPAC for permitting this bin to be trialled on their site. We would also like to give thanks to Azzurri Concrete for their input during the construction.

This video shows the second blowback in the same bin without being emptied. PumperDump believes a modest improvement as such could save concrete pumping companies, builders and concrete suppliers money over the duration of a project.

How you ask?

While the delivery line is short and the bin is set in place, you will be able to get a couple of blowbacks into the same bin before it needs to be emptied. Depending on who is paying for the current blowback truck, this could reduce the blowback bill considerably. The bin is also ready at your disposal if there are any problems to occur during the pour – so no waiting for a blowback truck to arrive when time is crucial.

For builders, concreters or concrete suppliers who care about sustainability, there is far less truck movement, reducing the carbon usage associated with a blowout as well completely eliminating the use of plastic, strongly keeping to our policy of no plastic in any of the equipment or waste stream.

Lastly, for the concrete suppliers. There is no need to immediately cart concrete to your yard – reducing fuel consumption, turnaround time for the next load is much quicker, as well as reduced tipping or carting fees for the removal of waste concrete brought back to your yard.

So, depending on who you are in the industry there is a saving for you!

As this is a new system, we have a very limited number of 5m3 (5 Cubic Meter) bins. Nonetheless, we are more than happy to talk to any party interested in using a 5m3 on their current or new projects.

Agreeing on a Problem that Needs to be Solved

In summary, the problem associated to the residential builder, is the same as the builder who uses the washout bags, washout trays and piles the concrete in a heap. They all have a degree of hidden costs associated with the handling of the concrete washout waste.

These range in degree of costs in the areas:

  • Use of plastic
  • Use of onsite plant
  • Time for manual labour to clean up messes
  • Extra tip fees
  • Uncontained water runoff and possible pollution infringements
  • Giving the recycler a plastic contaminated product to recycle
  • Unnecessary carbon emitted
  • Unsustainable practices while dealing with concrete waste
  • Onsite safety

I ask you, is this because the builders view the concrete industry like it was in the 1930’s, or because they believe there is no other option on how to deal with this waste, or is it because builders just don’t notice all the hidden costs associated with this process?

Building the Sydney Harbour Bridge

I have on many occasions taken people through our cost comparison chart and they have agreed with the cost savings in using PumperDump, then continue to go back to the same old ways. Change is hard, I know because I also need to do it, but change is what drives improvement.

Even though the word “Sustainability” hasn’t been shouted until recently, the practices have always been there when improving site safety, the environment and the bottom line. Sustainability is now expanding the core areas and the responsibility along the chain is becoming more accountable.

The belief that the waste in the bin is someone else’s problem, is now coming back to the creator of the waste. Builders need to and are becoming more aware of their responsibility on running a building site.

Concrete pumping has never been scrutinised under a microscope, but if viewed through a sustainable lens, builders can reap large benefits over large projects when these practices are implemented.

If you are facing the same problems as theses other builders and are willing to look for a solution and a better way, give me the time to show you what we can offer.

My next post,  what you have told us you need, to solve this problem.

A Sustainable Solution

Builders have been telling me that they need a sustainable solution to address the problem.


Sustainability is defined as the ability of a system to exist constantly at a cost, in a universe that evolves towards thermodynamic equilibrium, the state with maximum entropy. In the 21st century, it refers generally to the capacity for the biosphere and human civilisation to coexist. For many in the field, sustainability is defined through the following interconnected domains or pillars: environment, economic and social. 

Sustainability is not environmentalism and people in the construction industry are slowly recognising the difference.

The Venn diagram shows how sustainability intertwines different areas to achieve a better outcome. Sustainability is slowly becoming the way to do business as large funding organisations are requiring better accountability before finance is approved.

Adams, W.M. (2006). The Future of Sustainability: Re-thinking Environment and Development in the Twenty-first Century. Report of the IUCN Renowned Thinkers Meeting, 29–31 January 2006 (PDF). Retrieved 16 February2009.

The increasing focus and relevance of sustainability in the construction industry is more than just ‘being green’, sustainability encompasses, social, environment and economic, and I believe that “concrete pumping” as an industry, needs to be viewed in a new light as it has a major role in construction and the hidden costs and opportunities for a sustainable process should not be overlooked.

My next post, a solution proposed.

Aggravating the Process and Contributing to the Waste

I have tried not to make any comments in the past posts but, I was confused why the builder was even using the tray when all they would do is tip it into a pile on the ground. The pile of concrete is contaminated with plastic from the tray lining like the other methods mentioned in my previous posts.

The piling and removal of the concrete would mean double, even triple handling of this waste. This pile would only amount to a very small portion of the leftover concrete on this site. What a mess!

Concrete mixers have also poured their remaining concrete on the pile instead of returning it to the batching yard. This will save the builder money, but now the builder will need to organise a machine on site with a hammer to break up the concrete before it can be loaded and taken to a tip or recycler.

The mess left over is quite obvious. It may bother some builders and maybe not others, having a site with this amount of slurry left that could create a hazard, a cost and generally poor look.

My next post,  summary of the problems.
