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 SUPER SHIELD TPO is a high-performance, heat-weldable thermoplastic polyolefin (TPO) waterproofing membrane available in 1.2 mm and 1.5 mm thicknesses. It is designed for roof waterproofing and heat-reflective protection in both new and existing structures.
The membrane features a white textured heat-reflective top layer and grey bottom layer, providing long-term protection against water ingress and extreme weather conditions while maintaining flexibility and structural integrity.
MAK ELASTOTHANE ALP 111 is a single-component waterproofing coating based on aliphatic polyurethane technology. After curing, it forms a seamless, highly flexible and durable waterproof membrane with excellent crack-bridging performance.
Transparent Acrylic Dispersion Coating for Stone, Masonry & Concrete Surfaces
MAK CLEARCOAT AC is a high-performance, water-based transparent protective coating based on advanced acrylic dispersion technology. It is designed for natural stone, concrete, masonry, mortar joints and mineral façade surfaces, providing long-lasting protection while maintaining the substrate’s original appearance.
Its self-crosslinking polymer technology provides strong adhesion, high alkaline resistance and excellent protection against staining, efflorescence, dirt accumulation and water absorption.
