Using AB Fieldstone's two piece system for straight walls is quick and easy. Lay the top course down on the bead and press firmly. Do you still need to figure out the square footage for your project? Marty: From the ground, essentially is what you want to do..
Kendall: All right, very good. And are there other types of block we could use in a project like this? Marty: Right. There are several other types of block and size and colors to choose from. Most of the others have a lip on the back and they have a batter so they step back each course. They just kind of all fit into each other?
Marty: Right, these are angled already so we can alternate them to do a straight wall or turn them around to do a radius. Kendall: Ah, OK. Marty: Oh, so very easy to use. Very simple and then again cutting we would be using our hammer and chisel or the saw and splitting those in half. We have a manor stone, which is 6 by 16 and weighs 60 pounds and then a cottage stone 4 by 12 which is 40 lbs. Marty: Sure, so you have a lip on the back of the block that just really helps you align the block.
So, this would sit on top and the next course would sit on top and the lip would you have butt that out and that would align the block, the lips can be aligned for the base course..
Kendall: But.. Kendall: Oh, great. Summertime is backyard improvement season for homeowners and it seems that many people enjoy the cost savings and sense of satisfaction of completing a Do-It-Yourself DIY landscaping project.
Building with retaining wall block is a popular choice for DIY landscaping projects ranging from raised garden beds to taming hillsides and creating terraces or stairways. Not sure what you want to build? After the base course of block is installed, you will need to install perforated drainage pipe behind this first course of block. Water will flow down through the backfill material to the base of the retaining wall.
The drainage pipe will be located here to move the water away from behind the wall. Water hydrostatic pressure is the leading cause of retaining wall failures. Adding proper backfill to your retaining wall is extremely important as this is a key element in helping divert water away from the back of the wall, eliminating hydrostatic pressure, the leading cause of retaining wall failure. NOTE: If using block that requires pin connection, insert pins prior to backfilling to prevent gravel from plugging pin holes Description in Step 4.
The width of backfill area will vary depending on your specific project, but expect to fill 12 inches behind the back of installed block units. Backfill and compact behind each course before installing additional courses. NOTE: For compaction, a vibrating plate compactor or hand tamper is suggested. Do not use jumping or ramming type compaction. The next step will be to start adding additional courses. This is where your landscape wall will really begin to take shape.
Continue alternating between steps 3 and 4 until your retaining wall has reached the desired height. Each retaining wall block style will require a specific method of connecting each unit to the course below.
As you add additional courses, you will utilize the connection method specific to the style of block you are using. The final step to finishing your wall project is the addition of a wall cap. There are a variety of caps to choose from that compliment each individual wall style.
The addition of a cap adds a finished look to the final product. See all available wall caps. Once the wall has reached the desired height, clean off the last course of block in preparation for the cap or coping to finalize the wall. This can be accomplished by brushing with broom or hosing off. Once units are dry and clean, use construction adhesive for a mechanical bond. Cap may be flush or overhanging as required by aesthetics and design.
