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 aggregates since 2007 and have been instrumental together with the late Dr. Brian Hawkins and Mike Eden (Sandberg LLP) in developing protocols for the investigation and evaluation of pyrite in both aggregates and blocks.  We have carried out numerous investigations of aggregates and blocks containing pyrite which formed essential evidence in several high profile court cases.

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

James Lombard has served on the National Standards Authority of Ireland (NSAI) technical groups since 2012 and was instrumental in the development of IS 398-1:2017; and IS 465:2018. James has delivered presentations on these standards to various professional bodies and stakeholders.
