Executive Case Summary
The Karen Slope Containment Challenge
A luxury residential estate in Karen required structural waterproofing for a large concrete infinity pool and an adjacent 80,000-liter underground drinking water reservoir. Due to the villa's steep slope placement, any structural tank leakages could saturate the soil matrix and trigger landslides, risking the entire building foundation.
The Dual-Component Polymeric Basin
Phemat applied a fiber-reinforced, flexible dual-component cementitious tanking membrane to the internal walls. The swimming pool was treated with chemical-resistant epoxies to withstand chlorine sanitizers, while the drinking cistern was sealed with certified food-grade, VOC-free coatings to ensure safe potable water reserves.
⚠️ Ingress Challenge
The water tank required absolute chemical safety protocols to avoid drinking water contamination while resisting permanent hydro-pressures.
🛠️ Engineered Solution
Using certified food-friendly, VOC-free coating materials, the tank passed all public health certifications with superb structural performance and zero drop in daily water meter levels.
