WRW are proud sponsors of the Cardiff Blues and Scarlets Premiership Select kit for this season's British and Irish Cup campaign.
The shirt will be worn exclusively by the respective regions' Premiership Select XV - a squad containing a mix of academy players alongside representatives from the regional clubs.
The new shirts were worn for the first time last Saturday when Cardiff Blues Premiership Select XV played London Scottish at BT Sport Cardiff Arms Park and the Scarlets took on Nottingham Rugby at The Bay.
Business Development Director Jon Williams said: "We have built a successful relationship with the Blues over the past two years, and are delighted to continue this into a third season. It is important to us to support the development of young talent across the region and this is highlighted in our deal to sponsor the shirts for the British and Irish Cup campaign."
"WRW has developed a great deal over the past 30 years to become one of Wales' leading construction companies. While the business has grown in that time to now deliver projects through the whole of Wales and Southern England, we are proud of where we've come from, and particularly proud, to be continuing our support of the Scarlets."
