Renowned for delivering high-quality projects ranging from intricate commercial buildings to expansive infrastructure projects, their dedication to excellence is renowned, along with a profound commitment to sustainability and environmental stewardship.


The diverse and often transient nature of John Sisk & Son’s projects presented a unique challenge: providing high-quality, functional, and sustainable workspaces for their on-site teams. The company sought a solution that would not only offer practical benefits but also align with their ambitious sustainability goals. They needed workspaces that were adaptable, eco-friendly, and reflective of their brand’s commitment to making a positive impact on the environment.

The Solution: Sustainability at the Core

“At Sisk, we’re dedicated to leading the way in sustainability, ensuring that our projects not only meet but exceed environmental standards. CabinTec’s innovative approach to eco-friendly cabins has been instrumental in helping us achieve our sustainability goals,” remarked Barry Murphy, Plant Operations Manager at John Sisk & Son.

CabinTec’s designs focused on energy efficiency, utilising sustainable materials, and minimising waste, thereby significantly reducing the environmental footprint of temporary construction site setups.

Tailored and Efficient

Working in close collaboration with John Sisk & Son, CabinTec developed customised cabins that were specifically engineered to meet the unique demands of each project site. Rapid deployment and flexibility were key, ensuring that these eco-friendly solutions were delivered swiftly and could be adapted or relocated as project needs evolved.

Promoting Environmental Welfare

CabinTec’s cabins were not only designed with sustainability in mind but also aimed to enhance the overall site welfare. By providing a comfortable, safe, and energy-efficient environment, these cabins supported John Sisk & Son’s workforce, fostering well-being and productivity on site.

A Partnership for the Future

Throughout the nine-week test period, the Sanispace Solar single toilet demonstrated excellent performance. Data gathered revealed the toilet was used an average of 16 times per day, indicating its reliability and efficiency in meeting the site’s sanitation needs. The solar panels provided 100% of the electrical energy required, even on days with minimal sunlight.

The Solar Toilet boasts an exceptional battery life, capable of operating for 20-24 days on a full charge. This remarkable autonomy is achieved through its efficient solar panels, which actively recharge the batteries from March to October, significantly reducing the need for external power sources. In the winter months, to maintain the batteries’ longevity and performance, it is advisable to top them up via mains electricity every 10-14 days, ensuring consistent and reliable operation throughout the year.



The implementation of the Solar Toilet brings numerous benefits, including reduced carbon emissions, minimised noise pollution, and decreased dependency on fossil fuels. In addition to its environmental advantages, the Solar Toilet also offers cost savings. Compared to a standard diesel-generated toilet, this unit can provide up to an 80% reduction in running costs.

One of the UK’s and Ireland’s top contractors Fox Contracts who are responsible for major landmark

projects, building roads and public infrastructure have recently invested in their cabin fleet with an order for 21 “Foreman” Anti-vandal cabins from CabinTec.

Fox Contracts recognised the build quality and long-life expectancy of the cabins as their reason to invest with Cabintec.

Fox contracts are also doing its part to help the environment by specifying eco-efficient and energy-saving cabins with double glazed PVC windows, high-density insulation, digital room thermostats, and energy-efficient heaters.


The cabins have been custom made, painted with the company’s colours and are made up of a

combination of toilets, drying rooms, canteens, and open-plan offices, all of which will be located at

different sites throughout the country.


We moved into phase 1 of our new manufacturing facility in January of this year, and we are excited

to announce that phase 2 will be complete by the end of summer.


With this expansion, we will have a purpose-built factory of 30000 sq/ft that will allow us to develop

more new products and reach new levels in our manufacturing capabilities.


Phase 2 will house our fabrication team, our new paint oven, and blast booth. The facility will enable

us to bring our entire production process in-house, giving us complete control over the quality of our

builds at every stage of production, while also letting us schedule production to meet demand.


We are excited about this phase, which will help boost the local economy and open up new

employment opportunities.
