The project presented unique technical and operational challenges:
• Severe cracking and water leakage across multiple points of the RCC dome.
• Compromised drainage system, accelerating water ingress and concrete decay.
• Fragile surface prone to chipping and damage from previous repair attempts.
• Restricted working hours (only after school hours) and strict pollution control norms limiting work windows.
• Unpredictable rainfall causing reapplication delays and surface failures.
• The need to retain the heritage terracotta appearance while delivering long-term waterproofing and structural safety.
Makphalt executed a multi-layered restoration and waterproofing system, combining advanced repair materials and high-performance coatings:
• Damaged sections rebuilt using Mak Microcon (high-strength microconcrete, >40
MPa) and Mak SBR Latexfor flexibility and adhesion.
• Mak Plast ShotCrete 401 accelerator enabled fast-setting guniting even in winter,
reducing early curing time to 15–30 minutes.
• A 20–40 mm shotcrete layer with Mak Crete MWP polymer provided structural
flexibility and crack resistance.
• Surface finished with Mak Polytop PMM polymer-modified mortar to smooth
contours and enhance durability.
• Application of Mak Elastothane EMB (black PU base coat) with Mak Polyscrim
Cloth reinforcement for crack bridging up to 2 mm.
• Top finish with Mak Elastothane EMW-WB (UV-resistant, water-based PU coating)
in terracotta color, restoring heritage aesthetics.
• Structural Integrity Restored: Verified by the consulting structural engineer, confirming long-term safety and strength.
• Comprehensive Waterproofing: Leak tests confirmed 100% watertightness post-application.
• Aesthetic Revival: The dome’s original terracotta look was preserved and enhanced.
• Sustainable Maintenance: A long-term maintenance contract was established to ensure easy future touch-ups and inspection.
• Client Satisfaction: The Modern School Board appreciated Makphalt’s technical expertise, site discipline, and respect for heritage conservation.
MAK PREMIX is an instant road repair compound manufactured using a blend of bitumen, graded aggregates, and high-grade polymers. It ensures immediate bonding with the existing road surface and allows fast, durable repairs without the need for heating or curing. It is ideal for quick restoration of traffic-worthy pavements in heavily trafficked areas.
Applications
Repair of potholes on roads and highways
Utility cut repairs in urban pavements
Airfield and industrial pavement maintenance
Emergency repairs in hot, cold, rainy, or adverse weather conditions
MAK FILLER BOARD is a pre-formed compressible board used as a joint filler in expansion and construction joints. It accommodates movement, prevents stress transfer, and provides a base for sealant application in concrete structures.
Applications
Expansion and construction joints in concrete
Used in floors, pavements, and slabs
Suitable for basements, retaining walls, and precast elements
MAK POLYSCRIM CLOTH is a high-strength polyester scrim fabric used as reinforcement in waterproofing and coating systems. It enhances tensile strength, tear resistance, and dimensional stability of membranes and liquid-applied coatings.
Applications
Reinforcement for liquid waterproofing systems
Used with PU, acrylic, and bituminous coatings
Suitable for joints, corners, and critical detailing areas
