Step & Landing Construction

Designing and constructing steps & landings out of brick, flagstone and segmental retaining wall stones in Philadelphia, Montgomery County, Delaware County and the Main Line PA. We can construct steps and landings with many different materials. The height and length of the change in elevation is measured to determine the number of steps, the height of each riser, and the length of each tread. This page is here to illustrate how we construct our steps, and should not be used as a how to guide for step construction. Many variables can affect how steps perform such as improper compaction against the foundation of new construction, soil type, depth of excavation, subsoil compaction, use of stabilization fabric, depth and compaction of modified stone base, and depth of bedding sand.
Steps shown were constructed by Robert J. Kleinberg Landscape Design and Construction. He is an ICPI Certified Concrete Paver Installer and a NCMA Certified Segmental Retaining Wall Installer. He is also an EP Henry Authorized Hardscaping Contractor, and has been designing and constructing patios, steps and gardens in Philadelphia, Montgomery County ( Lower Merion, Bala Cynwyd, Ardmore, Narberth ), Delaware County ( Havertown, Marple, Drexel Hill, Lansdowne, Springfield, Swarthmore, Ridley, Media, Upper Darby, Newtown Square, Radnor ), and the Main Line ( Bryn Mawr, Villanova, Gladyne, Wynnewood ) PA as a Landscape and Hardscaping contractor since 1986.

Step & Landing Construction

Before construction existing levels are checked, and the level for the steps or landing is determined. The height and length of the change in elevation is measured to determine the number of steps, the height of each riser, and the width of each tread. Attention has to be paid to level of the floor inside house, and the elevation of the threshold. Often the house itself is used as the top step into the house. This helps keep snow and rain away from the threshold and can cut down on the expense of the job. It is usually more comfortable entering and exiting the house if the top step, or landing at the top, is at least 18-inches wide. A call is made to PA One Call to determine if there are underground utilities in the excavation area.

Existing steps are removed, soil is excavated to allow for at least 6-inches of modified stone for the base, and at least 8-inches of buried wall stone. Laser level is used to determine elevations for the steps and the excavation.
For new construction (less than 10 years old) E.P. Henry recommends overdig stabilization to ensure proper compaction against the foundation of the house. (Improper compaction against the foundation is common in new construction).

Before Construction :

Existing steps removed, soil excavated, and subsoil compacted:

Stabilization fabric is installed over the subsoil. Modified stone 6-inches deep is installed in two layers and each layer is compacted. Notice laser level receiver and rod on the right side used to determine level.

Install Stabilization Fabric:

Install And Compact Modified Base:

One inch of coarse sand is spread level for the setting bed used to help level the wall stones. At Least one layer of wall stones is set below grade. Wall stones are filled with clean stone. For larger landings the area is filled with modified stone in 3-inch lifts and compacted. Smaller landings are built up solid with wall stones. Notice the third step goes solid all the way down to the base.

One inch of coarse sand is spread level to help set the wall stones:

At least one layer of wall stone is buried below grade. Wall stones are filled with clean stone:

Install additional layers with retaining wall adhesive, and fill with stone. Continue to add modified stone to fill landing area and compact in layers. Notice the stone on the second layer is still below grade on the left side. At least 8-inches must be buried on the side with the lowest grade. (The right side here)

Install additional layers with retaining wall adhesive:

Continue to build up and fill wall stones and landing:

Finish wall stones and start to install caps with retaining wall adhesive (bullnose pavers on this job). Corners are mitered here to bring bullnose edge to all sides of the steps. Pavers are installed in the top landing with a little crown to allow for drainage. Adhesive is not used on a few bullnose pavers in the corners yet to make installation of the railing a little easier.

Finish wall stones and start to install bullnose pavers (or caps) with retaining wall adhesive:

Install pavers in the landing with a little bit of a crown and finish installation of bullnose pavers:

(Railing installed by DeVito Brothers & Son of Ardmore, PA) After railing is installed the remaining bullnose pavers are cut around the railing and installed.
