Unlike what civilization might have told you, water softener salt, or any kind of salt for that matter, does not directly impact the truth of your concrete.

You are watching: Will water softener salt damage concrete

So if her brine tank ruptured overnight, or her backwash drainpipe has to be leaking for a while, permit me set your mind in ~ ease and say your concrete will experience no straight damage. However, in colder environments, cold snaps an unified with salt could cause lower high quality concrete to suffer damages over time.

What impact Does Salt have On Concrete?

Most water softener salt is nothing more than simple table salt, or NaClNatrium Chloride or salt Chloride. That is because of this no an ext harmful 보다 spilling part salt on the floor or a deicing compound. Certainly, in warmer climates, there is nothing come be concerned about.

However, if you are planning on making use of water softener salt together a deicing agent, there are some points to take into account.

So, will Water Softener Salt damages Concrete?

Research has presented that even after prolonged exposure to NaCl over there is no straight effect top top the degradation of concrete. Water softener salt thus forms no direct threat to the problem of her concrete.

There is a factor why every docks are led in concrete, the pontoons of deep-sea oil rigs room made indigenous concrete, and why we usage rock salt almost everywhere our facilities to protect against automobile mishaps during the winter. It works!

Why chemical Erosion Is not An Issue

Although some research study does display that Ca2+ and also Mg2+ can cause harm to her concrete, the calcium and magnesium concentration in backwash are just not high sufficient to cause any damage.




When salt and also concrete are an unified in colder climates there deserve to be an additional effects that can prove detrimental come the condition of her concrete.

There space two mains methods in i beg your pardon salt can cause damage to concrete both that which space dependent top top the initial problem of her concrete.

Concrete destruction Due come Rebar Corrosion

If over there are currently cracks within her concrete this might make it feasible for melting snow and also ice to seep into your concrete and also reach the inner rebar.

Rebars' main component is iron, i beg your pardon oxidizes together it come into call with water. This process is increased when the water has salt.

As the rebar in concrete starts to rust that will increase causing the concrete to crack further. This in turn opens up an ext access to the rebar result in an ext rust and accelerating the process.

Concrete degradation Due come Spalling

Even there is no rebar, the porous characteristics of concrete deserve to be that is downfall in colder climates once using salt together a deicing agent.

The damages occurs v a process called spalling, whereby the water seeps into the pores in ~ concrete. In ~ low enough temperatures meltwater include salt that has seeped into the pores might start come freeze and also thereby expand, for this reason cracking the concrete.

Most concrete will stand up to a frozen cycle with normal water. However, as NaCl is a hygroscopicA substance the absorbs humidity from the air compound it boosts the volume that water took in within the concrete by up to 10% thereby raising the amount of development that occurs.

In cooler climates, it might be worth looking at ice cream melt options that frozen at reduced temperatures.

How lengthy Does the Take for Salt To damage Concrete

That is tough to say, while it can take a lifetime. If the concrete currently is in a poor condition, one overnight drop in temperature can be enough to damage your driveway past repair.

How To protect against Salt damages To Concrete

Some measures could be taken to protect against spalling of her concrete during chillier times. New concrete have the right to be made to withstand water growth through the use of air entrainment.

Because the the air bubbles in ~ the concrete, the becomes more flexible make it much less likely come crack throughout a freeze-thaw cycle.

How come Seal Concrete from Freeze-thaw cycle Damage

It is feasible to shield currently concrete from freezing damage by using a concrete sealant that will seal the pores within your concrete thereby staying clear of water indigenous seeping into it.

Will A Ruptured Brine Tank damage Your Concrete Floor?

As long as your water softener is not situated in one area wherein temperatures drop listed below freezing during chillier periods her floor will experience no damages from a tank rupture.

The salt can, however, you might want to completely rinse that off together it deserve to irritate her skin or could reason harm to pet paws if around.
