Super Block.
Yep its the Thai insulation block.
http://www.superblock.co.th/what-is.htmSuperblock is a building material that combines lightweight with high strength and provides a number of advantages over alternative building materials through superior properties such as thermal insulation, acoustic dampening and fire resistance. Superblock is manufactured from cement , lime and sand which are all acquired from the local market, and are mixed with water to form a slurry,then Aluminium powder is added, which is the only raw material imported The aluminium powder reacts with lime to form millions of tiny hydrogen bubbles which expand the mixture and then diffuse from the material to be replaced by air. This process forms the micro - cellular structure, which gives the material its lightweight and excellent insulation.
Q Con, more blocks.

Ok I admit that this has nothing to do with Thailand, but I like it
http://www.koicymru.co.uk/construct.htmThese pages are designed to give some advise to koi keepers in the UK who intend to build a pond, but are uncertain how to set about designing and starting the project.
It is not intended to give full details on how to build it, but give you some thoughts that should help you with the design. Every one has there own thoughts on what they want.
In the United Kingdom because of the long winters it is necessary to have deep ponds of a minimum of 4ft 6ins, and preferably five to six feet deep if you intend to look after large fish, or do not live in the south of the country. For this reason the ponds described here fit within this criteria, and smaller shallow ponds have not been considered.
