Research Paper: Investigation of pyrite heave in Dublin, Ireland

Pyrite Heave in Dublin

Mourice Czerewko (AECOM) and John Cripps (University of Sheffield) have published a paper on the investigation of pyrite heave affecting properties in Dublin, Ireland. The authors report on a case study from north Dublin, where pyrite bearing fill had been used below the new-build property floor slabs.

The paper, titled “Investigation of destructive ground heave affecting new-build properties constructed using pyrite bearing fill in the Dublin area of Ireland” follows prior research on the Irish pyrite problems (click here to view literature on the Irish pyrite issues).

Abstract

“Although structural damage caused by the expansion of bedrock and fills due to the presence of pyrite has been documented internationally since the 1960s, there is an apparent lack of awareness of the potential for these problems in the construction industry, particularly the domestic housing sector.

HomeBond’s Repudiation of Purchasers’ Claims

Homebond’s repudiation of purchasers’ claims – was it lawful?

Joseph Tyrrell (FCII, FCILA, FUEDI-ELAE), an insurance claims expert from Dublin, has published an extensive report on HomeBond’s repudiation of purchasers’ claims under the Major Defects Warranty in the HomeBond Agreement for Damage by Pyritic Heave.

report executive summary

In the report summary, Joseph Tyrrell writes:

“Following a wide-ranging investigation, I am satisfied that HomeBond’s rejection of hundreds of its warranty-holders’ claims was invalid, for reasons which I have examined in detail in the main body of this report…”

“It is astonishing, to my mind, that no one in authority appears to have looked closely at the reasons given for wrongfully turning down so many Purchasers’ claims, but it seems that this is what happened and that HomeBond has thus far got away with its shameful behaviour.

Book: Pyrite: A natural history of fool’s gold

A natural history of fool’s gold

David Rickard (Emeritus Professor at Cardiff University, Wales, UK) has written a book titled Pyrite: A Natural History of Fool’s Gold. The book was officially published today (25th June 2015) by Oxford University Press USA.

Synopsis from amazon

“Most people have heard of pyrite, the brassy yellow mineral commonly known as fool’s gold. But despite being the most common sulfide on the earth’s surface, pyrite’s bright crystals have attracted a noteworthy amount of attention from many different cultures, and its nearly identical visual appearance to gold has led to tales of fraud, trickery, and claims of alchemy.

Research paper: sulphate-generated heave rates in Ireland

Sulphate-Generated Heave Rates

Bryan McCabe and others at the National University of Ireland, Galway, have published a paper on the quantification of expansion rates of pyritiferous mudstone-siltstone from Ireland.

The paper, titled “Pyritiferous mudstone–siltstone: expansion rate measurement and prediction” adds to existing research on the expansion of pyritic fills published by Maher et al., (2011) and Sutton et al., (2013). McCabe et al., (2015) show that the density of pyritic fill and the depth of submergence in water strongly influence the rate of expansion. Furthermore, the authors found that pyrite content was the major control on the degree of expansion.… Read the rest
