Works have recently been completed to replace the eroding Portland stone entrance steps at the Institute of Civil Engineers. Although they had not long been installed the original stonework was heavily weathering at an abnormal rate. The cause was originally considered to be down to poor quality stone or stone that not satisfactorily dried prior to installation. It transpired the issue was down to the products the in-house cleaners were utilising.

What made this particular set of steps uniquely challenging was the retractable steps that slid back to expose a disabled lift. Our masons worked closely in tandem with the specialist lift contractor to reinstate the treads and risers with a suitable hard wearing bed of Portland stone.

We also provided advice on the future cleaning regime.
