floor covering between strip foundations ?
Sounds obvious but eveyone seems to assume you just know.
If you build with strip foundations, what goes between them, i.e. on the sub-floor. Old days it was just earth, and lots of new houses are built on a slab, but if using strip foundations, what covers the sub-floor ? Simon. |

Old days it was just earth, and lots of new houses are built on a slab, but if using strip foundations, what covers the sub-floor ? IME most people seem to prefer deep strip aka trench fill foundations - i.e the concrete is brought up to 150mm or so of finished ground level. Topsoil should be removed from the area to be covered by the floor slab. The walls are built up to dpc/finished floor level and the floor slab is poured inside them, usually 100mm concrete on a polythene dpm on sand-blinded hardcore. You can get problems with the hardcore settling so it should be well compacted in layers of 225mm max and if the total fill thickness would exceed 600mm the floor should be suspended - i.e. bearing on the walls. Concrete beam and block is a favourite in this situation as it is quick and easy to install and provides a good working platform during construction. -- Tony Bryer SDA UK 'Software to build on' http://www.sda.co.uk Free SEDBUK boiler database browser http://www.sda.co.uk/qsedbuk.htm [Latest version QSEDBUK 1.10 released 4 April 2005] |
