Buildings with 1–3 storeys located along coastal areas or islands such as Phi Phi Island often face problems of cracks, settlement, and deterioration due to humidity and sea air. If left unattended, the beams, slabs, and columns may lose their structural strength and pose serious safety risks.

Samsaen Engineering Co., Ltd., a civil engineering specialist in Phuket and Southern Thailand, provides structural repair services focusing exclusively on the most critical components — columns, beams, and concrete slabs — to restore stability and extend the lifespan of buildings.

Concrete beams are primary structural members responsible for transferring loads from floors and walls to columns. If cracks, spalling, or steel corrosion occurs, immediate repair is required to prevent structural failure.

🔹 Remove damaged concrete until sound material is exposed and reinforcement steel is visible.

🔹 Clean and coat reinforcement bars with anti-corrosion material to prevent future rusting.

🔹 Patch the area with high-bond repair mortar to restore the surface.

🔹 For severe damage, strengthen with additional steel reinforcement or FRP (Fiber Reinforced Polymer) to increase tensile and bending capacity.

👉 Result: The beam regains its original strength and can safely carry design loads.

Concrete slabs directly carry live loads from occupants, furniture, and equipment. If cracks or leakage are left untreated, structural deterioration and safety hazards may follow.

🔹 Inspect cracks and leakage through visual checks or Non-Destructive Testing (NDT).

🔹 Repair with mortar patching or epoxy injection for crack sealing.

🔹 For weakened slabs, strengthen by overlaying additional concrete layers or adding reinforcement.

🔹 Restore the load-bearing capacity and ensure serviceability.

👉 Result: The slab becomes durable, safe, and fit for long-term usage.

Columns are the most critical structural members, as they transfer the entire building load from beams and slabs to the foundation. Cracks or corrosion in columns can potentially lead to progressive collapse of the entire structure.

🔹 Remove spalled concrete and repair cracks caused by steel corrosion and material deterioration.

🔹 Strengthen with FRP wrapping or concrete jacketing to enhance load-carrying capacity.

🔹 In some cases, steel jacketing is used to increase axial load resistance.

🔹 Verify that the column meets engineering safety standards.

👉 Result: Columns regain structural stability, ensuring building safety and preventing collapse risks.

Structural repair is not just cosmetic crack fixing, but a comprehensive process to restore stability, safety, and longevity of the building. Repairing beams, slabs, and columns must be performed by licensed structural engineers with in-depth knowledge of engineering principles and material behavior.

All works are executed by professional structural engineers, well-versed in both safety standards and island-specific conditions, such as high humidity and sea air exposure.
