Investor Gresham Private Equity

When Gresham Private Equity bought offshore oil & gas pipeline repair company Walker Technical through a new company, ICR Integrity, in 2011 it employed 45 people and had sales of £6m a year. While it was already present in 12 international markets, there was significant potential to expand into new regions.

With Gresham’s support, ICR has since expanded into new territories in the Middle East and Asia Pacific and bought three companies to bring the company into new service areas so that it can now address three major markets in the sector: specialist repair, corrosion and mechanical engineering. Between 2011 and 2013, ICR’s turnover increased five-fold to £30m and employee numbers reached 166. With the business firmly set on the path to further growth, Gresham sold ICR in March 2014 to Graphite Capital.

We are delighted with the success of our growth strategy and with the support we received from Gresham and HSBC. From the outset Gresham supported our vision for ICR.
