P J Edwards & Co Ltd was founded in 1972 in Dublin by Mr Joseph Edwards and initially concentrated on, and became identified with repairs to masonry arches and bridges using pressure grouting and guniting techniques. The successful delivery of these restricted access and awkward working conditions projects rapidly led to a reputation which allowed the company to progress into many other geotechnical activities. These included rock anchors, soil nails, concrete repairs, micro-piling, underpinning, marine works and ground stabilisation.

The company's growing reputation also allowed it to secure many high profile contracts associated with famous landmark structures in Ireland such as the St Patrick's Bridge in Cork. By the 1980s the company had expanded into the bored piling field and had become the leading piling contractor in Ireland.

The UK arm of P J Edwards now operates from a base in Scunthorpe, Lincolnshire, but delivers projects on a nationwide basis across the UK installing piled foundations for a wide range of functions.

Similar to the Irish business, the UK business benefits from the support of a shared internal fleet of drilling rigs which now incorporates rigs up to 130t in weight, and with capability to install bored piles up to 2.4m in diameter, and 50m in depth.
