Despite the poor weather in June, revenue climbed 15% to £280.1mln (H1 18: £244.3mln) in the six months ended 30 June,, while pre-tax profits jumped by a similar percentage to £37.1mln (H1 18: £32.5mln).
Public sector and commercial sales – which account for two-thirds of revenues – were up 21% year-on-year, including an 11% boost from the Edenhall concrete brick acquisition.
Chief executive Martyn Coffey said the first-half performance, coupled with a “strong” start to the second half, means the board “is increasingly confident of at least achieving its expectations for 2019”.
He added: “The group continues to outperform the Construction Products Association's ("CPA") growth figures, despite ongoing political and Brexit uncertainty.
The CPA's recent Summer Forecast predicts a decrease in UK market volumes of 0.3 per cent in 2019, followed by an increase of 1.0 per cent in 2020, while the underlying indicators in the New Build Housing, Road, Rail and Water Management markets remain supportive.”
