asked the Minister for the Environment if he has given serious consideration to the use of pre-stressed concrete floors as a competitive substitute for imported flooring which offers many of the following advantages: (1) fire resistance and safety, (2) cost competitiveness, (3) native material is used in their manufacture, and (4) quality is guaranteed as they are satisfactorily produced under strict control; and if he will make a statement on the matter.
Written Answers. - Pre-stressed Concrete Floors.

I can assure the Deputy that I have given serious consideration to the use of pre-stressed concrete floors in houses as substitute for timber flooring. I had this matter examined recently by my Department's inspectorate who have advised me that, on the information available to them, this type of floor is likely to be more expensive than the traditional timber flooring normally used in housing.
It is considered that pre-stressed flooring would be more appropriate for the construction of office blocks, flats and factories etc., and that it would have only limited application in housing construction. In relation to fire resistance and safety, I am advised that the traditionally constructed timber floor can meet the requirements as laid down in the proposed building regulations. On the question of the use of native materials, I wish to reassure the Deputy that local authorities are encouraged to use such materials wherever possible and practical.
Regarding local authority housing, it is a matter for the authorities themselves to plan their schemes and submit them for my approval. If any such plans contain proposals for pre-stressed concrete flooring they will be considered on their merits in relation to suitability, cost competitiveness etc. Should the Deputy have any information or evidence to support the use of this type of flooring I will be pleased to have it considered by my Department's inspectorate.
