Many applications use the most popular retaining wall style for medium to large heights. The four retaining walls most frequently are: Cantilevered Retaining Wall: Retaining walls alter a property’s landscape physically besides preventing soil erosion. In residential and commercial landscaping, retaining walls are typical. (Learn How To Build A Brick BBQ With Chimney) By the end, you’ll see many measurements needed to determine the size of your structure, which can affect your retaining wall height In our guide, you can learn more about building a retaining wall without a permit and how large it could be. Retaining wall construction isn’t like a regular building with upper or lower floors, yet many retaining wall designs are load bearing, such as tiered retaining walls.ĭo you need to build such a retaining wall and are unsure if you can build it yourself, or do you face permit requirements? How high can you build a retaining wall? Any retaining wall can rise more than ten feet, yet many walls are over three feet, and many municipalities require a permit to allow them to be constructed. One thing that could be tricky to fathom is how high can a retaining wall be. You can do certain things yourself, yet more substantial construction requires a structural engineer and many building permits. It’s not always simple to determine how high construction on your land may be.

Tamp as you go to ensure that there are no gaps. The gravel is put within the landscape fabric if it has been lined. Backfill The Retaining Wallĭrainage gravel should be placed in the excavation behind the wall. This will keep dirt from washing through the fill gravel and clogging the seams between the blocks.Ĭut landscape fabric into strips and drape them over the wall blocks, the bottom of the trench, and the dirt behind the wall. Install Landscape FabricĪlthough this step is occasionally skipped, it is a good idea to line the rear of the trench behind the retaining wall with landscaping fabric. For curved walls, the cap blocks must be cut along the sides to fit the radius of the wall. To secure them, apply exterior-grade concrete adhesive. Install the caps so that the fronts overhang the underlying blocks by about 1 inch. The top course is constructed with specific cap bricks, typically thinner than the wall blocks. The miter’s cut faces may be put together using exterior-grade concrete adhesive. If the wall needs to make a sharp angle, cut the blocks at a 45-degree angle where the wall changes direction. The best approach to cut blocks is generally to make a succession of cuts at progressively deeper blade depths. To cut the block, use a circular saw with a diamond blade for a smoother cut. ![]() Splitting can be accomplished by gently scoring the top of a block with a broad masonry chisel and hammer, gradually deepening the score until the block cleaves along the scored line. You may need to cut or break some blocks to complete the ends of the row at the ends of alternating courses. Continue for each block course until you reach the cap layer. Check that each block is moved forward such that the rear lip hits the blocks beneath. ![]() The block’s back lip should overhang and just touch the back of the previous row.įrom the middle, proceed to the left and right. This is known as a “running bond,” which guarantees the wall’s integrity by preventing vertical joints from overlapping. Establish Subsequent Coursesīegin the second course in the center of the wall, with the first block centered over a junction in the bottom base course. If you’re working with a side-to-side slope that necessitates a tiered trench, make sure the block courses line up properly as the wall increases. Use a staked string line to keep the edges of the blocks aligned on straight walls.Ĭheck with a carpenters’ level every few blocks to ensure the route is absolutely level from left to right and front to rear.
