"We have no reservations in recommending your method for soil nails and masonry anchors using the 32mm hollow GRP bar.
We have found they meet our specification for 'Cintec' anchors but are much cheaper and are exceptionally easier to use and adapt. Indeed we have had issues with Cintec where any change on site has meant the bars being returned to Cintec to be adapted at an extra cost and delay.
We have used them on numerous occasions including listed bridges and report no issues have ever arisen to give us reason to reconsider your proposals."
