After the house points are located on the flat cut basement pad the crew follows the string lines with lumber to set the rails. The rails allow us to set the level and direction of the footing with a much higher precision than a trench footing installed by equipment and operator.
CONSTRUCTION sERVICES
The footing is by far the area where the most variables exist. It all starts with the end use in mind. How much earth does the wall have to retain and does it have to do it alone or with help? House footings utilize the wall connection to the floor system of the home for extra strength versus a Retaining Wall (RW) footing where the wall has to hold back the earth alone with nothing connected at the top.
PRE-CONSTRUCTION
After the concrete is pumped, short vertical dowels are placed into the wet concrete for the wall rebar. These short verticals will be extended to the full height of the wall and then horizontals will be added.
Retaining Wall footings require far more set up prior to concrete placement than do regular house type footings. Because the wall (added later) does not have a floor system or other connection at the top of the wall, R/W footings rely on a cantilever effect of a larger, heavier footing to hold the wall straight up and down.
After the inspections have passed concrete is delivered. Most all job sites require us to pump the concrete to the footing to place it with the most efficiency.
Retaining Wall footings require extra bracing and meticulous lining of the dowels. These dowels must be straight in line within a +/- 1/2". You will not be able to modify them after the concrete is set up.

The rebar is installed after the rails are leveled and remaining dirt is excavated by hand with shovels and picks. All ECF1 footing carry a minimum of (2) #4 sized pieces of rebar continuous throughout.
FOOTINGS
Our services range greatly following the experiences of the owners/operators. ECF1, LLC can assist in Pre-Construction Analysis as well as the actual work.
Retaining Wall footings also require a different method of vertical dowel installation. The dowels are different in that they have a leg bent at the bottom to add strength to the cantilever effect as that is the area with the most pressure on it.
Retaining Wall footings are a bit more difficult to get the concrete installed correctly around all of the vertical pieces of rebar. The concrete must be very level so the wall panels set level on the footing.
