What Our Customers Say

Over the years Keohane Readymix have been wonderful supporters of us in Innishannon Tidy Towns. If we need gravel, sand or readymix for a project it is just a phone call away. They receive any request with the utmost courtesy and deliver at any hour convenient to us.

They keep all the roads around their gravel pit in pristine condition and if you were to drive along the road fronting their works you would be totally unaware that any industry was going on in there. Over the years they have planted and enhanced the surrounding Bandon valley. Their tree planting has been a huge enrichment to our area.

Keohane Readymix is an example of a community conscious operation and we in Innishannon Tidy Towns are very appreciative of their support and their environmental concern for the Bandon Valley. We consider ourselves very lucky to have them as part of our community.

Consol Concrete specializes in mass concrete floors using Laser Screeds. As the sub-contractor responsible for laying and levelling large concrete pours on construction sites around Cork County, we are always happy to see the arrival of Keohane Readymix trucks to site. We were delighted to partner with them on the Courtstown Little Island Project.

Their quality and service are second to none which makes our lives that little bit easier. Very happy to recommend them.

Jonathan Nolan | MD Consol Concrete

It is my pleasure to recommend the services of Keohane Readymix. They have supplied MMD Construction with Concrete and Aggregate products for over a decade and in that period we have found that they take a very professional approach from tender stage to delivery and completion stage and have always provided innovative solutions.

Keohane Readymix are a very competent, skillful and proficient company and I would have no hesitation in recommending them.

Martin O'Brien | Purchasing Manager MMD Construction

KPH Construction has been buying from Keohane Readymix for many years. They deliver various materials to us a number of times every month including concrete, blocks, sand and aggregates. We also use Citymix in Cork city very regularly to deliver bags of sand, small quantities of concrete, blocks, and aggregate. Their trucks are a lovely size for fitting into tight spots around the city. They are extremely accommodating and their drivers very helpful onsite.

By this stage, we now know nearly all the drivers and everyone in the office by name. They provide excellent customer service and they couldn’t be more obliging, especially if you’re stuck – they will go out of their way to help you out. I wouldn’t go past Keohane Readymix for all our materials requirements. The product quality is always reliable, as is their service and I’m delighted to recommend them.

In many respects, Cahalane Brothers is very similar to Keohane Readymix in that we are both family businesses that have been in operation for many years based out of West Cork. We like to support other local businesses and first began buying from Keohane’s back in 1980. Since then, we have partnered with them on numerous projects.

We purchase mainly readymix concrete and blocks but they also supply us with aggregates and sand from time to time. In 2015 we worked with them on the Mill extension for Drinagh Co-op and we completed works on the new Clonakilty Black Pudding building, which we’re very proud of. Keohane’s have excellent technical knowledge and are very reliable in terms of supplying products that comply with all the latest technical standards and they have good follow through on after-sales service for example, concrete cube sampling for quality control purposes.

Their service is also second to none – the Keohane family themselves are very hands-on, especially when it comes to big pours, with well-timed deliveries and consistent quality from one load to the next. The level of contact with them is excellent – we know Mike and Eibhlin very well and wouldn’t hesitate to pick up the phone to them if we needed their advice or assistance. The fact that we’re a customer for over 30 years speaks for itself – Keohane Readymix is a very good company to deal with.

[Based in Dunmanway in West Cork, Cahalane Brothers Ltd provide construction services for Residential and Commercial projects in the Munster region in addition to providing service contracts for Cork Co. Co.]

Donal Cahalane | Project Engineer Cahalane Brothers Limited

We were very happy to work with Keohane Readymix on the Premier Inn project in Cork City Centre. Throughout the entirety of the project, Keohane Readymix demonstrated professionalism, reliability, and quality in their services as well as excellent customer service and support. We highly recommend Keohane Readymix to any construction project seeking reliable and high-quality concrete solutions and we look forward to working with them again in the future.

[Premier Inn Hotel Cork City Centre is located at Morrison’s Quay overlooking the south channel of the River Lee on a site that once housed the famous Moore’s Hotel. In a sensitive redevelopment of the heritage location, the new Premier Inn hotel was constructed alongside three own-door office buildings fronting onto the quay. Keohane Readymix supplied the readymix concrete, blocks and aggregates to main contractor Elliott Group on this prestigious project.]

Gerard McCaffrey | Group Head of Procurement Elliott Group

A family business like Keohane’s is a rarity in the construction industry today. We’ve used Keohane’s for supplies of materials for many years and on numerous construction projects, including the Courtstown Little Island Project.

We choose to work with Keohane Readymix for their personal approach, attention to detail and exemplary service, in addition to the quality products we know we can rely on. We share the same vision of delivering projects efficiently, effectively, and to the highest industry standards.

Dan O’Sullivan | MD Summerhill Construction

Michael [Keohane] and his team have a long history of supplying L&M Keating with consistently reliable high quality concrete in both our marine and building divisions. The technical expertise offered by Keohane’s is second to none.

It is my pleasure to recommend Keohane Readymix.

Richard Browne | Director L&M Keating

A trusted partner in our business, Keohane’s expertise and experience in agricultural builds has been instrumental in driving our farm developments. Their recommendations and advice on our new animal housing project from conception to completion has been invaluable.

The quality of their products and workmanship is of the highest standard. I wouldn’t hesitate to recommend Keohane Readymix for farm construction projects.
