Cracks in AAC block walls are not just cosmetic β€” they’re early warning signs of movement, weak bonding, and long-term deterioration.

At 91SkylineWorks Pvt. Ltd., we follow a systematic retrofitting approach to ensure durable and reliable crack repair:

βœ”οΈ Cutting & opening the cracks properly
βœ”οΈ Surface treatment using SBR Latex bonding agent
βœ”οΈ Fixing reinforcement chicken mesh with mechanical nailing
βœ”οΈ Rebuilding and sealing using high-strength SP40 Repair Mortar

This process helps improve bonding, reduce future crack propagation, and restore the wall’s integrity effectively.

Because real repair is not about hiding cracks β€” it’s about solving the problem at its root.

That small crack you see today… can become a serious problem tomorrow.

In many buildings, cracks are not just surface issuesβ€”they can indicate deeper structural concerns.

With Guwahati being in a seismic zone and exposed to heavy moisture, timely inspection is critical.

At 91SkylineWorks, our team of engineers uses NDT testing and advanced retrofitting methods to identify and fix problems at the root.

Soil Nailing Procedure

Soil nailing is a construction technique used to stabilize slopes, excavations, or retaining walls by reinforcing the soil mass. The method involves inserting closely spaced steel bars (nails) into the soil, which are then grouted into place, creating a composite mass that can resist the forces acting on it. Here's a step-by-step procedure for soil nailing:

1. Site Preparation

Survey and Design: Conduct a site survey to analyze the slope or wall and develop a design that specifies the length, diameter, spacing, and inclination of the soil nails based on soil conditions.

Excavation: Excavate the area in stages (called lifts) to the required depth. Each excavation is typically around 1 to 2 meters at a time to maintain stability.

2. Drilling Holes for Soil Nails

Drill Holes: Bore horizontal or slightly inclined holes (typically 10 to 20 degrees from horizontal) into the soil or rock mass. The diameter of these holes depends on the design but is usually between 75 mm and 150 mm.

Hole Length: The length of the hole corresponds to the design requirements for the depth of the nails, typically 3 to 10 meters, depending on site conditions and design.

3. Inserting the Nails

Steel Nails: Insert steel bars (commonly 25 to 40 mm in diameter) into the pre-drilled holes. The bars may be ribbed or deformed to enhance bonding with grout.

Corrosion Protection: If needed, provide corrosion protection for the nails, either by galvanizing the steel or applying epoxy coatings. Double corrosion protection is typically recommended in aggressive environments.

4. Grouting the Nails

Grout Injection: Inject grout (usually a cement-based mix) into the hole around the soil nail to bond the steel to the surrounding soil or rock. The grout is pumped under pressure to ensure full encapsulation and strength.

Grouting Techniques: There are two main grouting techniques:

Gravity Grouting: Gravity-based injection of grout, typically used for stable soils.

Pressure Grouting: Involves pumping grout under pressure for better soil contact and strength.

5. Facing Installation

Temporary Facing: Apply a temporary facing, such as shotcrete, wire mesh, or steel plates, to maintain stability during construction. Shotcrete is typically sprayed onto the excavated surface and nails to provide immediate support.

Permanent Facing: Once all nails are installed and stabilized, apply a permanent facing (shotcrete, cast-in-place concrete, or precast panels) to protect the surface and ensure long-term stability.

6. Drainage Installation

Drainage Provisions: Install drainage systems (such as weep holes or drainage mats) behind the facing to manage water buildup, which can cause pressure behind the soil nails and reduce effectiveness.

7. Monitoring and Testing

Pullout Tests: Perform pullout tests on some of the nails to ensure that they meet design strength requirements.

Monitoring: Continuously monitor the wall or slope for movement and stress on the nails during and after construction.

8. Final Finishing

Finishing: Once the nails and facing are in place and the structure is stabilized, apply finishing treatments, such as paint, protective coatings, or landscaping to improve aesthetics and further protect the system.

Key Considerations:

Soil Conditions: Proper geotechnical investigation is essential for understanding the soil type, water table, and other factors that influence nail design.

Nail Spacing and Inclination: These factors depend on the forces acting on the wall or slope and are determined during the design phase.

Safety: Ensure that the excavation is stable at all times to protect workers and avoid collapses.

Soil nailing is a highly adaptable and effective method for slope stabilization, particularly in urban areas where space is limited, and traditional retaining walls are not feasible.

πŸ—οΈ Retrofitting Services: The Importance of Treating Different Types of Cracks Without Delay! 🚧

Attention, homeowners and property managers! Are you aware of the various types of cracks that can appear in your buildings? Don't ignore these warning signs, as they could be indications of underlying structural issues. Today, we want to shed light on the different types of cracks and emphasize why they should be treated promptly by expert engineers.

1️⃣ Hairline Cracks:
These slender cracks, often barely visible to the naked eye, may seem harmless at first. However, they can potentially develop into larger cracks if left untreated. Hairline cracks are typically caused by minor settlement or temperature fluctuations. Although they may not appear threatening, addressing them early can prevent significant damage in the future.

2️⃣ Shrinkage Cracks:
As the name suggests, shrinkage cracks occur due to the drying and shrinking of building materials, such as concrete. They commonly emerge shortly after construction or major renovations. Although small in size, they can expand over time, leading to structural integrity problems. Prompt treatment by experts can prevent these cracks from widening and causing more extensive damage.

3️⃣ Settlement Cracks:
Settlement cracks are a result of uneven soil movement or improper building foundation. They often appear as vertical or diagonal cracks and can compromise the stability of the structure. Ignoring settlement cracks can lead to further foundation issues, including sagging floors, jammed doors, or even complete structural failure. Engaging expert engineers to assess and mitigate these cracks is crucial to maintain the safety and longevity of your property.

4️⃣ Structural Cracks:
The most severe and alarming type of cracks, structural cracks, can indicate major structural problems. These cracks are wider, deeper, and more noticeable than other types. They often result from significant structural damage, such as foundation settlement, excessive loading, or natural disasters. Immediate action by professionals is vital to assess the severity of the issue, recommend appropriate measures, and safeguard the building's occupants.

πŸ”§ Why Should You Rely on Expert Engineers? πŸ”§

βœ… Specialized Knowledge: Expert engineers possess in-depth knowledge of structural systems and can accurately identify the underlying causes of cracks.

βœ… Tailored Solutions: They can offer customized retrofitting solutions based on the specific type of crack and the unique characteristics of your building.

βœ… Preventive Measures: By addressing cracks promptly, expert engineers can help prevent further damage, saving you from costly repairs and potential hazards in the long run.

βœ… Quality Assurance: With their experience and expertise, professional engineers ensure that the retrofitting work is carried out to the highest standards, guaranteeing the safety and durability of your property.
