Steps Built into the Wall
With a Radius Turn
Before excavation can begin, the
rise and run of the stair treads
must be determined and codes
must be met. Stairs can be built
by stacking two Clifton units and a
Step/Cap on top of each other for
more stability. A more economical
option is stacking one Clifton and
a Step/Cap. Stairs can be built in
front of the wall or into the wall
with radius turns or outside 90º
corners (see illustrations below).
The depth of the excavation will depend on the height required for the risers and if you are stacking two
Clifton units or one. Install and compact a 6" base as the footing. Break off the rear lip of each block and
place them onto the base across the width of the stair opening. Level each block front to back and side
to side. Fill the open cores of the units and the spaces between them with ¾" to 1" processed gravel
and sweep the units clean. Construct the next riser assembly by placing and compacting another 6" thick
gravel footing behind the first course of units. Now place a row of Clifton units onto the base and position
them directly behind the units in front. Install successive risers in the same manner for the number of stairs
needed. The final step is to adhere the Step/Caps with construction adhesive and allow at least 24 hours
to dry.
