Patch Repair

- Partial depth repair
- Full depth repair

Shutter and Cast

Beam repairs using shutter and cast method Important: Use of temporary propping |

Gunite/Shotcrete

Advantages: Good consolidation Speed of application High build Limitations: High set up costs Uneven finish Messy |

Carbon Fibre Reinforcement

External reinforcement of concrete members Thumb of thumb 50mm strip equivalent to 2No Y16 bars |

Internal and External Application of Carbon Fiber Reinforcement on Telecommunication Monopoles Towers.

We, in association with a professional structural engineer, have developed a method of increasing the capacity of existing telecommunication monopole structures by internally fixing vertical carbon fiber strips at predetermined positions.

The system has been deployed successfully on several Monopoles in locations varying from coastal, escarpment and inland sites. We have also completed work on a camouflage monopole in an urban area.

DE ALMEIDA (MOSSELBAY)

-Strong Wind at the coast

- 55 M HIGH MONOPOLE
- 9 M2 ADDED CAPPACITY
- Cost effective (Average R 50,000.00 per m2 added)
- Can be designed for specific site requirements (No redundant capacity)
- Further upgrading possible after initial upgrading
- Quick installation time
- Reduced safety risks – no scaffolding
- No external sand blasting or repainting required
- removal of existing antenna not required
- No re-camouflaging
- Weather has little influence
