Bricks specs

Recommended Posts

Hi,

 

Part of the build is in a flood risk zone, with this in mind I was thinking of spec'ing bricks with less than 7% water absorption, this however limits the choices.

 

Do you think it is worth spec'ing such a low water absorption bricks? Also where do you call it, 7%, 10%, 13% etc.

 

Thank you in advance

Would using engineering bricks below dpc allay your concerns?

 

If other experts have done their job properly your above dpc flood risk must be very low.

It's also worth looking at the frost rating and the efflorescence rating.

Perhaps also where they are actually made. A lot of bricks with English sounding names are made in Belgium.
