![]() ![]() I was just too fking cheap to higher a decorator. Concrete blocks are naturally fire-resistent, highly durable, and its mass. Contact your Best Block representative for special requests and additional options. So I know a thing or two about retaining walls, building pools, landscaping and construction.Īs far as subing a custom home I could do it but would need quite a bit of help the first coupla times through.īTW U can call me Maurice as I even know interior design. 6x8x16 Knock-Out Bond Beam is a standard concrete masonry unit (CMU) that exceeds ASTM C90 standard specifications in all weight classifications. The re bar in the pool was set 4 inches on center, required 55 yards of Gunite and was 18 inches thick. One side of the pool itself acted as a retaining wall. If I recall the footing alone required 35 yards of concrete. On my last house I built 30 ft of 6 ft high, 105 ft of 5 ft high and 240 ft of 3.5 ft high CB retaining wall. So what you are in a sense building is a wall made of cement.īuilding a retaining wall otherwise with CB is a disaster waiting to happen. As a sample calculation, let us consider building a 3.0-meter wide and 2. Fire resistant (always check your local fire codes) Energy efficient. Precision concrete block for building masonry walls. Concrete blocks are naturally fire-resistent, highly durable, and its. Concrete cell fill calculator: sample calculation. It is energy efficient and resistant to mold, termites and fire. ![]() Add rain and strike three.įor a roughly 3 foot high wall chances are you will need a PERMIT.which will tell you what size block, how deep and how wide your footing has to be, how much re bar, and that you have to fill all the block cells with concrete. 6x8x16 Split Face Solid Bond Beam Block is architectural CMU that has the appearence of hand-chiseling to give wall designs a highly textured look. The horizontal pressure and change in coefficient of friction in the soil is a double strike. We,Silu Concrete, manufacture high quality 3 hole concrete hollow block having size 6816 inch in Hetauda. Last thing you want is for water or moisture to build up behind a wall like that. One of the main advantages of using concrete landscape wall units is they are typically mortar free and self weeping. I suggest you focus your research in that direction. ![]() There are special interlocking Concrete landscape units designed for your application. Retaining walls are notorious for failure, even knee height ones. The block has a compression strength of 2,200 psi and weighs 30 lb. Concrete Block for your next construction project. Features compression strength of 2,200 PSI for durability. Number of concrete blocks needed = 90 concrete blocksīy multiplying the core volume of a single concrete block by the number of concrete blocks needed to build the wall, we can then find the fill volume, as shown below:įill volume = core volume per concrete block × number of concrete blocks neededįill volume = 0.006424 m³ × 90 concrete blocksįrom our calculations above, we can now say that we need around 0.5782 m³ of concrete or mortar to fill the concrete blocks that we will use to construct our wall.Bad idea, even using a rule of thumb 1:4 width to height ratio for a parapet you exceed anything reasonable going that narrow. Made from high-quality concrete to ensure long-term use. Number of concrete blocks needed = 7.2 m² / 0.08 m² Number of concrete blocks needed = (3.0 m × 2.4 m) / (0.4 m × 0.2 m) Number of concrete blocks needed = (wall width × wall height) / (block width × block height) Now that we have all the details we need, we need to divide the total wall area by the area of a concrete block to find the number of blocks our wall needs: The core volume of a standard size 6-inch concrete block is approximately 392 in³ or 0.006424 m³. As a sample calculation, let us consider building a 3.0-meter wide and 2.4 meter high wall using 6-inch thick standard 8" × 16" (20 cm × 40 cm) concrete hollow blocks. ![]()
