If you are looking for the best way to secure your half wall with concrete, then you need to learn how to build a knee wall on concrete. You will see that building a knee wall on concrete is very easy and it is not difficult at all. If you want to make sure that your half walls remain strong, then you must follow this guide. Building a knee wall on concrete requires no special tools or skills.
You might wonder why you would want to use a knee wall on concrete? There are many reasons. One reason is because it is easier than other types of half walls. Another reason is that it provides better protection against fire damage. And finally, if you have a basement or crawl space, then building a knee wall on concrete may provide additional protection from water damage.
Building a knee wall on concrete does not require any specialized equipment such as cement mixers or power drills. All you need is a hammer and some nails.
How Do You Build A Knee Wall On Concrete?
Step 1: Measure the length of the side of your house or apartment. For example, if your home has two stories, measure the distance between each level. Then divide this number by 2 to get the total length (in feet). Step 2: Use a tape measure to mark off the desired height above grade. For example, if you want your knee wall height to be 4 feet above grade, then measure down 4 feet from the bottom of the wall.
Use a level to make sure that it is straight and write this number down. Step 3: Mark off the ground at this height in a series of small lines across the entire length of the wall. Step 4: Using a hammer and nails, fasten the first row of 2x4s to the ground along where you have marked off. You want the top of your knee wall to be 6 inches higher than grade. Use a level to check that it is straight up and down. Step 3: Nail your 4×4 posts or 6×6 posts (depending on the height you need) every 16 inches on center. Be sure to use a nail angled in toward the center.
Step 4: Cut your plywood or sheet good to size for each side of the knee wall. For every line on the ground, you should nail down one 2×4. Make sure that all of the 2x4s are straight and level with each other. Step 5: Place a row of blocks where the second row of 2x4s will be located. This is the bottom row.
Using the same technique as before, place the 2x4s evenly across the row. The blocks should be flush against one side of the row so that it looks similar to a brick wall. Be sure the height above grade is equal for each piece. Step 5: Attach these with nails or screws through the bottom side of the plywood and into the 4x4s. Be careful to leave a little space between the top edge of the plywood and the wall to allow for drainage.
Step 6: Fill in with more 2x4s or 2x6s, fastening them to the 4x4s and plywood to form your knee wall. This will fill in the wall and make it stronger. You can then finish it with stucco or brick to match your house.
How Much Does It Cost To Build A Knee Wall On Concrete?
The cost of building a knee wall on concrete mainly depends on what type of materials you decide to use. If you want to build it out of wood, then you can expect the cost to be around $200 for materials. This is not including any costs for your own time. If you want to use brick or stone, then you can expect the cost to be around $600 for materials. Again, this is not including any costs for your own time.
All things considered, building a knee wall on concrete is a fairly simple and cost-effective way to protect your house or apartment from water damage. It provides great support for the foundation of your house and keeps the ground from eroding away from under it. Whether you live in an area prone to flooding or not, this is a project that you should consider doing sooner rather than later.
With the rising sea levels as a result of global warming, you never know if your home might be flooded some day. It doesn’t hurt to take preventative measures now rather than deal with water damage to your house in the future. And besides, it’s a good idea for anyone who has a basement or slab on grade house.
