How to Repair Swimming Pool Cracks with Epoxy Injection? In Oman, 80% of swimming pools have significant water leakage. Continuous water pressure, temperature variations, and ground movement expose swimming pools. Over time, these conditions may cause structural cracks, leaks, or deterioration of the pool shell’s concrete. If not repaired properly, these cracks can lead to serious structural problems and costly water loss.

The attached photo shows the swimming pool before tiling, when it was filled with water to test its structural integrity. A significant water leak was observed throughout the entire structure.
Water Tech Fountains provides specialized swimming pool structural crack repair services in Oman using advanced epoxy injection technology, restoring the strength and water-tightness of reinforced concrete pool structures.
Common Causes of Swimming Pool Structural Cracks
Concrete swimming pools may develop cracks due to several factors:
- Improper concrete curing during construction
- Insufficient reinforcement or cover thickness
- Ground settlement or soil pressure
- Structural movement between the pool wall and the raft slab
- Honeycomb concrete or poor compaction
- Long-term water pressure inside the pool
Early identification and professional repair are critical to prevent further damage.

Cement bag paper is used as a packing material
- No rigid mechanical fixing to reinforcement
- Void pockets around fittings
- Poor compaction around pipe penetrations
- Likely honeycombing behind the faceplate
For swimming pools, fittings such as skimmers, inlets, and pressure jets must be mechanically
fixed before casting — not temporarily wedged with paper.

1. Structural Inspection and Crack Assessment.
Our technical team first performs a detailed inspection of the pool structure to identify crack patterns, leakage points, and potential structural defects. Reinforcement scanning may also be conducted to locate steel bars before drilling injection holes.
2. Surface Preparation
Loose concrete, plaster, and dust around the cracks are removed to prepare the structure for repair. The crack surfaces are cleaned and dried to ensure the proper bonding of the repair materials.
3. Injection Packer Installation
Small injection holes are drilled along the crack line at controlled intervals. Injection packers are installed to allow epoxy resin to penetrate deep into the concrete structure.
4. Crack Surface Sealing
The crack line between packers is sealed using epoxy paste to prevent leakage during the injection process.
5. Epoxy Resin Injection
Using specialized injection pumps, low-viscosity epoxy resin is injected into the cracks under controlled pressure. The resin penetrates deep into the concrete and bonds the cracked sections together, restoring structural integrity.
6. Repair Mortar and Surface Restoration
After the epoxy injection cures, packers are removed, and the repaired areas are finished using non-shrink fiber repair mortars. This restores the surface strength of the pool shell.
7. Waterproofing Protection
Finally, high-performance cementitious waterproofing systems with fiber mesh reinforcement are applied to ensure the pool’s complete water tightness.
