Replacing current cinder block retaining wall with brick?
Comments (4)There are no absolutes in life, so I'll amend pls8xx's statement: The new wall will very likely fail if constructed as you say. You're in a freeze-thaw part of the country, which is why your footer needs to be below frost line. If you attempt to "float" the footer, the expansion and contraction of the soil will heave and crack the footer, the mortar joints in the CMUs, and the brick veneer. You also need to consider that with a 3' high wall, the forces attempting to knock it over are pretty intense. Without being tied to a proper footer, and without vertical steel reinforcement, those forces will eventually win and your wall will very likely fail. Again, no absolutes in life; the brick piers on my 100 year-old house go 6" into the ground and sit on bare earth. But if you're taking the time and expense to do something, why build in the probability of failure? As to the EP Henry wall solution... did that quote also include demo & removal of the existing wall and related sitework? If so, they may not be that out of line. If you approach it as a DIY job, you may be surprised at how quickly $X per ton of disposal adds up. If you do the project yourself, be fanatical about following the manufacturer's instructions. These systems are designed so they can be installed without special masonry skills, but you still need to be very accurate in preparing the base. If you don't feel like you're spending a ridiculous amount of time getting the first course of block perfectly level... well, you're probably not doing it right. If you want to put a fence back on top of the wall, Keystone makes a system that'll hold the fenceposts securely within the structure of the wall. Might be worth looking at. Best of luck!...See Moreanother 120 foot retaining wall
Comments (7)Yo...Mama...a good trick I've borrowed (stolen) from some rock makers goes as follows... Start by adding a small amount of dry oxide color to your mix that will represent the "middletone" of the rock you want. Apply your mix to the target surface and quickly shape it into the rough forms you want. In several paper or plastic plates, have the lighter & darker colors you want to add. Using a very stiff paint brush or even a masons brush, pick up the other colors from the plates and "dab" them straight into the fresh mix where you want them. Try to keep your brush or brushes fairly dry and don't cross-contaminate the light & dark colors as you work. Once you have a workable area colored you can begin to blend the colors a bit. Once set, you can also come back with acid etch stains for additional effects. Notes: "Dabbing" with a very stiff brush (like the masons brush) creates a nice coarse texture. Another trick is to get some crushed Mica and toss small amounts onto the surface while it's still damp for a very realistic stone effect. And remember, all of the colors mentioned above are absolutely permanent and will never fade. Hope these notes help as I look forward to seeing another of your amazing finished products. All my best --- Tango...See MoreQuestions About Deck Footings & Ledger Board Attachment
Comments (4)At the very least, you need to use a CBS66 for your fence post. They are really not designed for non top supported posts. I would actually probably suggest to sink a PT post directly in concrete and form your curb around that. The stem wall should not be affected by the bolts passing through, but I would be concerned with how you fill in that 2 1/2" gap between the ledger and the stemwall. You probably need to go to a larger bolt size. That spacer should probably 1/4" galv. steel with Mallable washers on each end. I would think that one 3/4" bolt every 2' would be sufficient unless you are way off the grade. If it were me, I would make the deck free standing of the house and avoid all of the other stuff in regards to attaching to the house. If the deck is elevated 3 or more feet off of the ground, that would possibly make more sense to attach to the house. Since frost is not a problem in your area, base rock is probably not needed. Just make sure that the bottom of your footing is flat and compacted....See MoreRetaining Wall Footing
Comments (4)Correct on the retained earth being the critical dimension. We she retaining walls that retain 0 earth (but are 3' tall) and require almost no footing, to a wall that retains more earth requiring a larger base on the L of the footing. The keystone blocks are engineered to tell you how to do this - but you should have some help from a structural engineer here - especially if you are retaining earth at all - you'll need to extend the footing back further on the earth side, etc....See Moredrdna801
