Stone retaining wall repair firm in Colorado: Retaining wall drainage is an incredibly important part of building a stone wall. Once a few rows have been stacked, backfill the wall with rock so it matches the grade height in front of the wall, and then lay down perforated drain tile on top of the rock. Install drain tee fittings and a drain grate every 25 feet to 50 feet, depending on how much rainwater is expected to run down to the wall. Cut one block down to accommodate the drain grate. Screw the drain tile parts together so they won’t come apart when they get covered with more rock. Also, drain the tile to daylight at the ends of the walls whenever possible.
By using NFC you are basically increasing the depth of your retaining wall. Most masonry blocks would be an average depth of 200-250mm, by using NFC you are increasing that depth of your solid masonry block from 200mm up to 500mm (Infill depth) or more depending on the height of your wall. It is always recommended that every third or fourth block should have part of the back edge removed. This would give a far better adhesion tying the NFC infill layer and the NFC core filled blocks creating a far stronger structure.

Spacers are set to maintain spacing and support the form prior to the pour. Wire ties snug the form and resist the pressure of the wet concrete. Wales align the form and brace the studs in forms more than 4 or 5 feet high. Two horizontal walls are sufficient for most forms, but they should not be spaced greater than 30 inches on center. For lower, lighter walls, it is possible to cast the wall at the same time you cast the footer. Larger walls always require separate pours for the footer and wall.
A wall that leans into the soil it retains is less likely to be pushed outward by soil pressure than a plain-old vertical wall. Design and build your retaining wall to slope at a minimum rate of one inch for every one-foot of rise (height). Fortunately, working with retaining wall blocks makes it incredibly easy to achieve this “step-back” construction! The locking flange on the bottom edge of every block guides it to click into position slightly behind the lower block, preventing the top blocks from being pushed outward.
