    Yeah its available here. The beams are inverted T section precast prestressed reinforced concrete and the blocks are blocks. This floor works by casting on a (usually) 75mm reinforced screed over which will normally incorporate underfloor heating.
    Go some contact numbers back in the office, can post them up tomorrow.

    Anybody seen or used this beam and block method for a first floor instead of precast.

    Is it even available in Ireland?

    Hey there,

    They are commonly called T-Beams in Ireland and can be ordered through most precast suppliers who will most likely get them from someplace like Oran Precast in Galway. I'm actually in the process of building a balcony with them. I will pour about 5 inches of a screed on top of them. They should be a good job and 50% cheaper than the quote that I got for hollowcore for the same job. I have heard of people using them instead of hollowcore for full houses with no problems. I suppose they just have more manual labour to them than hollowcore, but if you are doing a self build, you should be able do a lot of the work with them yourself and save labour.

    Regards

    Dan

    I was thinking of doing this myself so saving on the cost of labour.

    But was thinking would i reall be saving. How would you complete the ceiling below it to include light fittings etc.?

    Is there enough room underneath the blocks and the bottom of the tbeam for wires and plumbing to fit? how would you fix the ceiling to the t-beams then?

    In a word no. You will have to use a suspended ceiling so make sure that you allow for this when determining your floor to ceiling height.

    Was thinking that.

    What is the best way to approach suspending the ceiling?

    You can batten out and slab it yourself but now its hard work. Or you can get guys who specialise in this. Time wise its better to get the specialists but will obviously cost you a bit more.

    Just wondering what is the best way of securing the battens. would you drill into the standard blocks above and secure with rawlplug wedge anchors? or is there another method?

    There will be a gap between the Conc Block and the timber battens due to the fat edge of T beam below. Therefore fixing to the blocks is not practicle. Would require tieing wire etc.

    You cannot drill the underside of the beams so clips need to be used

    See below (Extract From JP Concrete Products Ltd )

    A plasterboard ceiling can be easily installed using metal clips, 50 x 50mm timber battens and plasterboard; this inevitably increases the fire resistance. Ceiling Clips
    An aid for fixing plasterboard ceilings to the underside of the beam at upper floors.
