Road salt is an essential part of winter maintenance as it helps to keep the ground clear and safe.

However, if it is not stored/maintained correctly, it can cause problems such as clumps and hardening.

In this blog post, we will discuss why road salt clumps and how to prevent it from happening. We will also tell you about our gritting salt delivery service so that you can keep your premises safe when the season is here.

Common Reasons Why Road Grit Clumps

Warm Air and Moisture

One of the most common reasons why road grit clumps is because of the warm air and moisture, which can cause the salt to melt and then re-freeze. This process can damage the salt crystals and make them more prone to clumping.

Lack of Air Circulation

Another reason for grit clumping is a lack of air circulation.

If the salt is stored in an enclosed space without any ventilation, it can cause the salt to sweat and form clumps.


Another common reason for road grit clumping is incorrect storage. If the salt is stored in a humid or damp environment, it will absorb moisture from the air and start to clump.


Rain can also cause road grit to clump as it washes away the protective layer of salt that is on the surface of the grit. This exposes the grit to moisture and air, which can then cause it to clump.

And, living in the UK, the chances of rain are always high!

How to Prevent Road Salt From Clumping

The best way to prevent road salt clumping is to store it in a dry and well-ventilated place.

If you can, try to store the salt in a cool and dark place as this will help to prolong its life.

You should also check the salt regularly and break up any clumps that have formed.

How Long Can You Store Grit?

Road grit can last for a long time if it is stored correctly and kept dry.

However, if it is exposed to moisture or humidity, it will start to break down and become less effective.

It is important to check the salt regularly and make sure that it is still in good condition.

If you are unsure whether the salt is still usable, it is best to edge on the side of caution and purchase new grit.
