Pyrite Testing (IS 398-1:2017/SR21:2014+A1:2016) and Block Testing-Pyrite and Mica (IS 465:2018)

Ground Investigations Ireland Ltd. have been involved in the sampling and testing of pyrite in hardcore since 2007 and have been instrumental together with the late Dr. Brian Hawkins and Mike Eden of Sandberg’s in developing protocols for the investigation and evaluation of pyrite in hardcore and blocks.  We have carried out numerous investigations of hardcore and blocks containing pyrite which resulted in a number of high profile court cases.

We also offer the full range of testing blocks for Muscovite Mica which has caused serious problems in blocks particularly in Donegal.  We offer a full service for the evaluation of deleterious material (Pyrite and Muscovite Mica) in hardcore and blocks in both existing structures and for materials to be used in new structures.

James Lombard has served on the NSAI technical groups since 2012 and for the development of IS 398-1:2017; and IS 465:2018 and given presentations on these standards to various professional bodies.
