On the Collection Page, tap on the "Estimate Your Wall" button to enter the estimating tool or tap on any of the other windows to visualize what you can do for your project.

Step 1: Draw Your Retaining Wall

Once in the estimating tool you may begin by drawing your retaining wall by entering the locations of your wall by simply tapping your finger on the screen to indicate the start of the wall, any location where a wall bend may occur and at the end of the wall.

If at any time you wish to remove an entry point, you may double tap on the screen to remove the last point. Triple clicking the screen will clear all the points on the screen.

You can navigate to the next screen by clicking the green arrow at the top right. The measuring tape button, also at the top rights of the screen is a switch between English units and Metric units and the question mark button is a link to this help screen.

After entering your wall locations, tap on the green arrow to continue.

Step 2: Add the Wall Heights

Enter in the wall heights of each of your previously identified locations. The wall height is defined as the total difference between the soil at the bottom of your wall to the top of your cap.

The app automatically defaults to the maximum allowable wall height of 6 ft. To change height values, simply tap your finger at the location which you wish to change the value, once highlighted, enter in your new wall height value ranging from 0 to 6 ft and then select OK.

Once your height values have been entered, tap on the green arrow to continue.

Step 3: What is Above the Wall?

The app allows you to select between three different top of wall conditions:

  • Flat – A wall that has grass or plantings directly above it with very little slope.
  • Slope – A wall that has grass or plantings directly above the wall, but has a maximum 3:1 slope.
  • Driveway – A wall that has a driveway above.

After identifying your top of wall condition, tap on the green arrow to continue.

Step 4: What Type of Soil Do You Have?

The type of soil you have at the location of your retaining wall can play a role in how the wall will behave once it is constructed. The app allows you to select between two soil types, clay soil and sandy soil. If you are not sure what type of soil you have for your project, assume clay soil. Once you have selected your soil type, tap on the green arrow to continue.
