The remaining concrete on the top step has been coated with a bonding agent to increase the adhesion of the new concrete.
Steel mesh is then screwed down onto the old concrete and 1½” of concrete is applied to the tread portion of the stair. A final ½” of fine, finish concrete (i.e., with smaller aggregate) will be added to the top of the stair.
Our plan is to do the tread (top) portions of each of the other stairs, and then return to the top to apply about 2” of concrete to the riser (front) portion of each stair.
The edge of each stair will also be rounded off and the tread portion brushed to provide greater traction during bad weather.
Since the old concrete has degraded because of the amount of salt that must be applied during the winter to melt snow and ice on the stairs, a roof will be installed over the stairs. The new roof will reduce the amount of snow and ice that land on the stairs, and therefore should also reduce the amount of salt that we need to apply to keep them clear during the winter.
The work should continue through the coming week. Our thanks to our dedicated Trustees for these comprehensive repairs and improvements that should give us many years of maintenance-free use!
