The surfaces at NTPC Barh were heavily weathered and damaged, creating several challenges:
• Fungal and bacterial growth due to prolonged moisture exposure.
• Cracking and dust formation weakening the concrete substrate.
• Large-scale surface repairs required before coating application.
• High elevation work areas, causing logistical and safety difficulties during material shifting and application.
• Additionally, due to the scale of the project, maintaining cost efficiency and product performance was critical for long-term maintenance planning.
Makphalt proposed Mak Elastothane EMB, a high-elongation, eco-friendly,
polyurethane-based elastomeric membrane designed for heavy-duty
waterproofing and weather protection.
Damaged concrete areas were repaired to ensure sound
substrate for coating adhesion.
A total of 35 tonnes of Mak Elastothane EMB was applied by BEM
Enterprises, ensuring uniform film thickness and seamless waterproofing.
For high-elevation work zones, workers were secured with
ropes and harnesses, and material movement was carefully planned to ensure
safety and efficiency.
• Enhanced Durability: The coating provided a long-lasting barrier against moisture, dust, and fungal attack.
• Cost Efficiency: Reduced consumption and fast application ensured significant cost savings compared to competitors.
• Improved Aesthetics & Protection: The treated surfaces were revitalized, offering both aesthetic improvement and functional waterproofing.
• Client Satisfaction: NTPC appreciated Makphalt’s technical support, on-site safety management, and the superior performance of Mak Elastothane EMB under challenging site conditions.
MAK POLYPLAST SUPERLAY MINERAL FINISH is a five-layer polymeric waterproofing membrane featuring a 160 GSM non-woven polyester mat as its central reinforcement. SBS/APP polymer-modified bitumen is provided on both sides of the reinforcement to deliver high softening point, heat resistance and waterproofing performance.
The membrane incorporates a thermofusible high-molecular HDPE film on one side and UV-resistant mineral granules on the other side. Its polymeric construction provides 60% elongation and high tensile strength to accommodate structural movement and adapt to different contours.
MAK POLYPLAST SUPERLAY ULTRA is a high-performance SBS-modified elastomeric bituminous waterproofing membrane reinforced with a heavy-duty non-woven polyester and additional protective fleece layer.
The membrane features an engineered mineral crystal finish on the upper surface and a heat-activatable thermofusible film on the underside. It is designed to develop a continuous and uniform bond with freshly poured structural concrete, providing resistance against hydrostatic pressure and mechanical stresses.
Special selvedge technology enables secure side-lap welding using torch application or hot-air welding.
MAKFELT is a bitumen-treated hessian-base waterproofing felt conforming to IS 1322-1993. It consists of a continuous hessian sheet uniformly treated with bitumen and finished with mineral powder to prevent sticking between layers and provide additional surface protection.
MAKFELT is designed to be used as part of a built-up bituminous waterproofing system, with bitumen layers applied above and below the felt.
