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 TURBO GROUT is a rapid-setting, high-performance cementitious grout designed for fast repair and anchoring applications. It develops high early strength, allowing quick return to service, making it ideal for urgent repair works and time-sensitive projects.
The product provides excellent bonding, non-shrink properties, and durable performance under load.
MAK INJECT 1C SOIL is a single-component polyurethane injection resin specially designed for soil stabilization, ground sealing, and water control applications. It reacts with moisture present in soil to form a rigid or semi-flexible foam, filling voids and binding loose soil particles to improve ground strength and reduce permeability.
The product is ideal for geotechnical and underground applications where soil consolidation and water ingress control are required.
MAK HYDRO INJECT 2K 902 is a two-component hydrophilic polyurethane injection resin designed for effective sealing of water-bearing cracks, joints, and voids in concrete structures. It reacts with water to form a flexible foam or gel, creating a durable and impermeable seal that stops water ingress.
The system is specially developed for controlled injection applications where flexibility and long-term sealing performance are required.
