Aldabra (Test Bores)

HC Deb 17 November 1967 vol 754 cc211-2W

Mr. E. Rowlands

asked the Minister of Public Building and Works how deep were the test bores on Aldabra, carried out by his Department.

Mr. Mellish

To varying depths, up to 13 feet.

Dr. Ernest A. Davies

asked the Minister of Public Building and Works what tests he has conducted on the suitability of material from the East Channel of Aldabra for runway construction.

Mr. Mellish

No tests have been made on material from the East Channel itself, but laboratory examination of samples from test bores at the east end of the Atoll, and available information on the properties of chloroformations, indicate that the material to be excavated from the Channel would be suitable for filling under airfield pavements. Harder material for pavement surfacing would be available on the airfield site.
