Stonewall Step Installation

The "Cut" Method

With the “cut” method, a gravel base is used under each stair. An advantage to this procedure is that it allows you to adjust the height of the rise. Generally, 6" to 8" is acceptable, although local building codes may specify the required height. The depth of the excavation will depend on the height required for the risers and the coping style used. The height of the first riser should measure from the top of the tread to the finished grade.

Stonewall -

Start with the corners and build them as you normally would in the style you want, either curved or 90°. To avoid the automatic step-back as you construct the side walls, do not use the pins to connect the full size Stonewall units. Instead, lay each course vertically, with no setback and bond the units together using our SRW Adhesive. Otherwise, you will need to cut the riser and coping units to fit the space created by the step-back developed in the side walls. Once the side walls have been erected, you can start the stairs at the front or set them in from the corners. At least one full size Stonewall is used under each stair tread to provide stability. The depth of the excavation will depend on the height required for the risers and coping style used. Install and compact a 6" gravel base as the footing. Place a row of Stonewall units onto the base across the width of the stair opening and level them front to back and side to side. Fill the open cores of the units and the spaces between them with 11/2" processed gravel and sweep the units clean. If you have decided to use two courses of Stonewall units for each stair, insert the pins and position the second row.
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 Stonewall units onto the base and position them directly behind the units in front. Finish as noted above. Install successive risers in the same manner for the number of stairs needed.

Treads

Once the stair risers have been constructed, you will need to set the treads. Adhere the style coping unit you have selected with SRW Adhesive as instructed in Section 7 - Capping the Wall. Position the treads to provide a 1" overhang. Allow the adhesive to cure at least 24 hours before opening the stairs to traffic.
