Step-by-Step Guide to Install Split Face Block

Follow these steps to ensure a successful split face block installation, resulting in a durable and visually engaging outdoor feature.

Preparing the Site

1. Clear the Area: Remove all surface vegetation and debris from the site. Avoid using this material as backfill due to its potential to trap moisture and promote settling.
2. Excavate the Base Trench: Dig a trench that matches the designed width and depth. Typically, the depth should equal the height of one block unit plus 6 inches, while the width must equal the width of one block unit plus 12 inches to accommodate proper drainage and stability.
3. Base Material: Fill the trench with a clean 3/4" crushed gravel, around 6 inches deep. Compact and level this base to form a solid leveling pad, which prevents settling over time. Do not use pea gravel; it does not provide the same level of support.
4. Leveling: Verify that the base is perfectly level, both front-to-back and side-to-side. If the grade alters along the wall's length, create a stepped leveling pad to maintain a regular baseline for the blocks.

Laying the First Course

1. Place Base Course Blocks: Lay the first course of split face blocks on the prepared leveling pad. Ensure each block is level and consistently aligned with adjacent units. Utilize a level to check each position.
2. Adjust as Necessary: If any block does not maintain the desired level, remove it, make the necessary adjustments to the base, then re-lay it. This ensures a solid foundation for subsequent courses.

Mortaring and Stacking

1. Apply Mortar: Use a trowel or spreader to apply mortar on the top surface of each block in the first course. Ensure an even distribution, which offers strong adhesion for the next course.
2. Lay Additional Courses: Place subsequent courses of blocks on top of the first, staggering joints between layers for stability. Align each block carefully, using a level to check both front-to-back and side-to-side positions continuously.
3. Compress and Tidy: Apply firm pressure to seat each block properly into the mortar. Clean excess mortar promptly for a neat finish, enhancing aesthetic appeal.

1. Backfill: After stacking the split face blocks, backfill behind the wall with engineered material. This material aids drainage and adds stability, preventing soil erosion and ensuring wall longevity.
2. Install Geotextile Fabric: Place geotextile fabric between the backfill and soil to prevent sediment from clogging drainage paths. This helps maintain wall integrity over time.
3. Final Mortar Touches: Inspect the mortar joints for any voids or gaps. Make repairs where necessary to enhance the visual aspect and structural integrity of the wall.
4. Curing: Allow the mortar to cure properly for optimal adhesion. Keep the area wet as needed, ensuring the curing process achieves maximum strength.

Maintenance Tips for Split Face Block

• Inspect your split face block regularly for signs of damage, such as cracks or shifting. Address any issues promptly to prevent further deterioration.
• Clean the surface of the blocks periodically to maintain their appearance. Use a stiff brush and mild detergent mixed with water to remove dirt and moss. Rinse thoroughly afterward.
• Apply a sealant designed for masonry to increase the longevity of the blocks. Sealant helps protect against moisture, stains, and provides an additional layer of durability.
• Ensure drainage is effective around the blocks. Maintain proper landscaping and grading to direct water away from the wall, preventing erosion and settling.
• Trim vegetation near the blocks to avoid moisture retention and root invasion. Roots can destabilize the structure over time.
• Refill any gaps or areas where backfill has settled. Utilize gravel or soil to keep the wall stable and secure.
• Monitor the mortar joints between blocks. If any deterioration occurs, re-pointing with a suitable mortar mix helps maintain the integrity of the wall.
• Consider periodic power washing to remove tough stains. Ensure you use appropriate pressure levels to avoid damaging the block surface.
