KIS INTERNATIONAL SCHOOL – PATHUM THANI (Lotus Building) Structural Strengthening and Crack Repair for Long-Term Safety

Project Overview

The Lotus Building at KIS International School in Pathum Thani exhibited significant cracking and lateral sway due to side pressure, which compromised the structural integrity of the reinforced concrete columns. Left unaddressed, these issues could pose long-term risks to safety and usability.

To resolve this, Smart and Bright Co., Ltd. executed a comprehensive repair and strengthening protocol using state-of-the-art materials and methods.

Materials and Methods Used

✅ Crack Repair:

Employed SmartInjection EP21, a high-pressure epoxy injection system
Fully sealed and restored the monolithic nature of the columns
Prevented further crack propagation and deterioration

✅ Structural Strengthening:

Wrapped the entire column height with SMARTFIBER SHEET UT70-30
A high-strength CFRP (Carbon Fiber Reinforced Polymer) material
Significantly improved shear and flexural resistance to counteract sway

🛠️ Installation Process

Structural inspection and crack mapping
Pressure injection of SmartInjection EP21 into identified cracks
Surface preparation and wrapping with SMARTFIBER SHEET UT70-30
Quality control using Non-Destructive Testing (NDT)

✅ Project Outcomes

Columns structurally restored and reinforced to handle operational loads
Reduced sway and increased safety for building occupants
Enhanced building performance while preserving original design

Demonstrates engineering excellence in educational facility retrofitting
