What can we do for stadiums?

The concrete in stadiums deserve some special attention

What can we do for stadiums?
22 September 2020 Posted in

Stadiums large and small are the scene of sporting events, rock concerts, and other mass gatherings of humanity. And of course none of the visitors is thinking about the concrete supporting the event!
Markham
If you want your stadium to last its intended service life, at minimum maintenance cost, then there are some important factors to consider for the concrete.

Markham

TRAFFIC WEAR

Some parts of a stadium will be under high foot traffic usage. Other parts may be subject to vehicles. The slab surface will, of course, tend to wear under the constant traffic, ultimately resulting in concrete dusting and reduced coverage of the reinforcing steel.
Markham
That same traffic will bring water, oil and street grime onto the paths, floors and any concrete seating. Water carries contamination deep into the concrete, setting up the factors for corrosion of the steel.

Also, that same traffic will wear away any surface coating which is applied as a surface sealer. Surface sealer coatings are supposed to be re-applied periodically even when they aren’t under traffic. It’s doubtful how often that happens in accordance with the datasheet.
Markham
We’d like to introduce AQURON 2000 – multi-benefit concrete treatment.

AQURON 2000 penetrates deep into the concrete (around 150mm) and seals the porosity with anti-dust hardening.
No surface sealer to wear away! No need to re-apply – ever! The concrete floor slab is hardened and durable for the full intended service life of the structure.
Markham
Better still, if AQURON 2000 is applied at curing stage, there’s no need for a separate curing compound or time-consuming water curing. AQURON 2000 enhances concrete curing, equal or superior to 14 days’ water curing.

FOOD AND DRINK

High sugar levels aren’t just unhealthy for humans. Did you know that tomato sauce, and cola drinks, are both extremely toxic for concrete? Seeping into the concrete, sugary moisture will react within the concrete, destroying the protection the reinforcing steel requires. This applies to concrete grandstands, and any concourse or pathways.

Protect the concrete by sealing the porosity with AQURON 2000.

LOOK UP!

Another place that’s often overlooked (underlooked?) is a ceiling or soffit. This may apply under grandstands or in public car parks.
Markham
Here again, AQURON 1000 can help, by penetrating, sealing, and binding up the reactive elements within the concrete. AQURON 1000 is a very effective anti-dust treatment for concrete ceilings.

TAKE IT TO THE TOP LEVEL

… and you get the added factor of weather exposure.
Markham
Long story short, exposed concrete such as grandstands or roof decks absolutely must be protected against the weather.

Rainwater and wind combine to wear away exposed structures at the best of times. Add in that oil and road grime we mentioned, and you’ve got a serious recipe for premature concrete decay.
Markham
Steel corrosion and internal concrete reactants cause cracking. Little cracks become big cracks, and big cracks kill concrete.

Here’s where the AQURON waterproofing system comes into play.

 

This three-part system completely removes the need for a membrane and consists of

  • AQURON 300 waterproofing admixture
  • AQURON 2000 spray-applied penetrating treatment
  • CONQOR 47B delayed swell water stop for joints and penetrations

A complete waterproofing system, ideal for roof slabs and other exposed structural elements.
And by the way, it also suits basements. But, in a way, that’s another story.

EXTRA CREDITS

A frequently asked question we get is “Is AQURON compatible with line marking or epoxy coatings?” YES.

AQURON does not introduce any element not already present in the concrete.
Any coating designed for bare concrete will work as normal on AQURON-treated concrete.
Markham

So – if you’re designing or constructing a stadium (or a basement for that matter) why not get in touch? Let’s see how we can help make your concrete stronger, and last longer. And probably save you some time and money along the way.
