1. Retaining Wall Blocks / Stones Construction Requirements

(1) Masonry mortar materials used in retaining wall construction, including cement, sand, and water, must comply with construction specifications. The mortar must meet the design specifications outlined in the construction details and should be mixed thoroughly. One batch of mortar should be used up before it sets.

(2) The masonry body must be constructed using slurry masonry. During construction,砂浆 should be laid first before placing the stones. The stones should be layered and pressed in alternating horizontal and vertical joints for stability. The height difference between adjacent construction sections should not exceed 1.2mm, and each layer should be roughly leveled. The division points should be as close as possible to settlement or expansion joints.

(3) Before laying mortar, the stone should be wetted with water to ensure its surface is fully saturated, without any standing water remaining. The thickness of the mortar joints should generally be 20-35mm, with larger gaps filled with碎石.

(4) All stones must be placed on freshly mixed mortar, ensuring it is well-filled. There should be no direct contact between stone joints, and it is not permitted to construct by placing side-standing stones on the outside and filling the center.

(5) Mortar should be full and neatly jointed with a natural, even, and aesthetically pleasing appearance. The block stone should maintain a smooth surface. Any mortar splatter on the masonry surface should be cleaned off.

(6) Structural dimensions and locations of the masonry must comply with the construction details. Surface deviations within a 2-meter range must not exceed 30mm. Masonry joint widths: flat joints 15mm, vertical joints 20mm.
