Modernstone is our flagship segmental retaining wall system. In masonry retaining wall, weep hole is made by removing mortar at the side joints and distance between weeps is around 80 cm. For out-of-plane bending of solid grouted walls allowable flexural strength can be estimated based on flexural tensile strength of the grout per Equation 1. Though the MSJC code recognizes reinforced masonry shear walls with no shear, or horizontal reinforcement, it is recommended that mortarless walls be rein- forced with both vertical and horizontal bars. Base of the Wall. Place it so that the 3/8-inch gap is filled. Test data (refs. Texture: Medium Grain. The International Building Code (ref. Can I used dry Quikrete to achieve improved . 1) with Equations 7, 8 and 9. The compressive strength of theparging material should be equal to or greater than that of the masonry units. The purpose of both types of retaining walls remains the same: to prevent soil erosion and to maintain the contours of the land. When working with QUIKWALL, rubber gloves and safety glasses should always be worn during mixing and placing procedures. Each type will give your wall a different look and feel, so make sure you look at pictures to determine which would be the best fit for your house and landscape. Retaining Walls. Simply stack them in rows or mix heights within a row for a random look. Stresses in reinforcement and masonry compressive stresses are assumed to vary linearly with strains. The lip design helps to snug blocks against each other to create a tight interlocking joint. A 50 pound bag will cover approximately 50 square feet at a 1/8" thickness. Due to the roughness of the unit surfaces, high stress concentrations can result which can lead to higher non-proportional creep deformations. ASTM International, Inc., 2002. Segmental retaining walls are modular block retaining walls used for vertical grade change applications. Horizontally reinforced bond beam lintels can be created using a grout stop beneath the unit to contain grout.
