From a small company set up at the home farm in 1990 producing ready mix concrete, RTU is now a hugely successful company working out of a purpose-built manufacturing plant in Newtownabbey.

As an innovator, RTU introduced Factory Produced (Tubbed) Mortar in 1992, Ultraflo Hemihydrate Floor Screed in 2008, Exposa Decorative Concrete in 2013 and Conveyored Concrete in 2016.

Our advanced batching plant has the capacity to produce over 90m3 of concrete per hour and our quality control systems ensure a perfect product is delivered every time.

RTU is also passionate about the environment and at our recycling plant we reduce, recycle and reuse materials whenever possible.

We are an innovative company, looking to the future, researching new products that will meet the ever-changing demands of our customers throughout Ireland.

RTU is committed to providing and maintaining the highest standards of health, safety and welfare for all our employees, whilst ensuring we comply with all relevant legislation.

We have a proactive approach to managing Health, Safety and Welfare through hazard identification, risk assessment and providing appropriate control measures.

We firmly believe in upskilling our employees to train them to a high level of competence and have a comprehensive training package on Health, Safety and Welfare.

To ensure ongoing improvements, we have an audit system in place to promote continuous improvement and behavioural compliance.

At RTU we firmly believe that it is our staff who make us successful. All our departments work seamlessly as a team to deliver the best product and service to our customers.

We understand that motivated staff make more productive staff, so we invest heavily in training and development to maintain a positive and happy workforce.

More importantly, our staff work in partnership with our customers in order to ensure a quality product is delivered on budget and on time, every time.

RTU operates a quality control system which ensures our products comply with the relevant British and European Standards. Our computerised batching plant ensures a consistent quality product with full traceability with each batch.

Our in house lab continuously tests raw material and finished product to ensure we produce quality products of the highest standard and to specification.

RTU quality control is third party accredited by BSI, and we sit on the MIA technical panel, which is the recognized authoritative UK voice on mortar technology.

RTU is dedicated to implementing and maintaining environmental operations which lead to improvements in the communities where we do business, and which foster a sustainable future for all.

This means continually seeking to reduce the environmental impact of our activities and implementing new technologies and methods of work which are targeted at the reduction or elimination of emissions and greater efficiency in the use of energy and resources.

We are committed to reducing, recycling and reusing materials wherever possible within our Newtownabbey plant and we actively abstain from damaging the natural environment. RTU operates an Environmental Management System compliant to ISO14001 and is 3rd party accredited by SGS.


Our vision is to expand nationally and be known as the number one preferred supplier in our industry; to be the company that consistently delivers the best quality and range of ready mixed building products.

We will never compromise on the quality of our service and product.

We aim to always attract the highest calibre employees and help them realise their full potential.


Through continued innovation, to produce the best ready mixed building products to meet the increasing demands of all our customers within the self-build and construction industries in Northern Ireland, and to deliver these products with the highest levels of customer service.


The service, quality of product and the expertise of staff at RTU makes my job as Site Foreman a lot easier. RTU is a great supplier, easy to work with and always dependable.

For the last five years, RTU have been the chosen supplier of ready mixed mortar to all our sites in the Greater Belfast area. They provide a competitively priced, high quality product and back this up with a very reliable delivery service.

I initially chose to use RTU because of their high level of service. They have a reputation for delivering on time and for a great range of quality products which are always of the same consistency. As a bricklayer working against deadline, all of these are very important. I find the staff in the despatch department very helpful and courteous. The drivers are the same. I would give RTU 10/10 for overall service.
