Longley has three production plants in London, Dewsbury and Northern Ireland with the capacity to produce flooring for 30,000 new homes a year.
Latest filed results for the year to July 31 2018 show Longley made a pre-tax profit of £1.14m from a turnover of £22.7m.
The deal was announced in a positive set of interim results from Ibstock which revealed a pre-tax profit of £41m from revenue of £203m.
Ibstock Chief Executive Officer Joe Hudson said: “We are pleased to be announcing today the acquisition of Longley Concrete, a highly complementary addition to our concrete business.
“Overall, market fundamentals in the UK are stable, with low interest rates, high employment levels, good mortgage availability and the Government’s Help to Buy scheme all remaining supportive.
“This should continue to underpin activity levels in the new build housing market over the medium term.”
Ibstock’s existing concrete business includes the Forticrete, Supreme and Anderton brands.
