An instant emergency shelter which hardens to concrete and can be set up in an hour is to be manufactured in Wales.
Will Crawford and Peter Brewin, both 28, created the "concrete canvas" shelter while studying at university in London together.
Mr Crawford said the pair, who were inspired by the material used to make plaster casts, have already had interest from the military and aid organisations.
He said, "It takes two people about an hour to put it up, then it takes 12 hours to set.
"The shelter can be used in post-disaster and post-conflict situations. They are ideal for extreme environments, and they also offer protection from small arms fire and shrapnel.
"Interest in the shelters has been phenomenal so far."
The building, which is fireproof and designed to last for up to 10 years, is delivered in a bag.
Water is added, to activate dry concrete within the material, and the structure is then inflated, pegged down like a tent and sprayed with water.
The completed building, which sets as solid concrete, stands at 54 square metres.
The shelters are to go into production at their plant in Pontypridd in eight months' time.
The former students of the Royal College of Art and Imperial College, London, will also be selling concrete cloth, the material used in the shelters, within the next two months. …
