How to cure concrete blocks after palletising: why pallets need humidifying and the 2 common systems, shower room and inline roller shower.

Key takeaways

Moistening the pallets 24 hours after initial setting, before palletising, makes the most of the concrete's potential strength.
Slow drying prevents pieces from cracking and losing strength.
A 'shower room' (ceiling fitted with water sprayers) or a shower-type system at the roller-table exit are the two usual curing options.

Why is it important to humidify the pallets?

In this article, we look at why it's important to humidify pallets after the initial curing period, 24 hours before palletising.

Humidifying the blocks lets you make the most of the maximum strength concrete can provide, and slow drying prevents the pieces from cracking and losing strength.

How to achieve good curing after palletising?

There are two common systems:

Shower room: a building with a roof full of water sprayers. Pallets stay here for a few days before sun exposure, keeping them in a suitable environment until delivery to the customer.
Inline roller shower: a water mechanism at the exit of the roller table that soaks the blocks as soon as they're made, providing the water concrete needs for curing.
