I am currently paving one half of my back garden, the intention being to have a nice little wiggle to the edge where the lawn is. I had aquired some old house bricks which I wanted to use to edge the paving to give it some character and support. However.... a friend has now told me I can not use these because they are too absorbant and will explode if they get frosty :p
Is this true? If it is will it take a long time to explode (How big an explosion will it be!!!!??? )
Thanks to any advice, this website has been a god send as I am a slight novice!
the bricks will absorb water and when its cold enough for them to frost/ice, then the ice will expand and start to split,crack and break the bricks into pieces, they probably wont blow up in a massive explosion or anything lol. but they shouldnt be used for this type of work because they will crumble through time into pieces causing the paving to creep and move apart.
