Residential Foundation Seismic Retrofit: FRP Grid Foundation Reinforcement Method

Construction while living in the house is possible! A new seismic reinforcement method for residential foundations that can be adapted even in narrow spaces has arrived!

In conventional residential foundation reinforcement methods, long curing periods were often required due to construction circumstances and the need to secure working space, making it difficult to carry out work while living in the home. The "FRP Grid Foundation Reinforcement Method" achieves both construction in narrow spaces and while living in the home. The method involves "chipping away the decorative mortar of the existing foundation" → "fixing an FRP lattice to the existing concrete with anchor pins" → "applying a specialized mortar at a minimum thickness of 15mm," making it possible to work even on small sites without the need to relocate outdoor units, piping, gutters, etc., or remove flooring materials. Additionally, it is possible to complete the work in an unprecedented short time of as little as 3 days. 【Necessary Qualifications for Design and Construction】 ■ Designers - First-class/Second-class/Wooden Architect - Participants of the seminar "Seismic Diagnosis and Reinforcement Methods for Wooden Houses" (organized by the Japan Architectural Disaster Prevention Association, etc.) - Participants of technical seminars organized by our company ■ Contractors and Construction Managers - Participants of technical seminars organized by our company *The technical seminars organized by our company are conducted in a format where the responsible person visits directly.

Repair of the drainage connection and main pipe with a strong integrated method: "FRP Internal Reinforcement Method."

Partial repairs of steps, pipe misalignments, joint misalignments, cracks, etc. in the drainage pipes. Extension of the lifespan of sewer systems, agricultural water, industrial water pipes, etc. (light curing, heat curing).

The FRP internal reinforcement method (light curing) is a technique for partially repairing unevenness, pipe wear, joint misalignment, cracks, and other issues that occur in sewer pipelines. The repair material is attached to the construction machine and is introduced from a nearby existing manhole, then transported to the targeted defective area. Next, the repair material is pressurized and adhered to the pipe wall, and by using a heater or ultraviolet lamp built into the construction machine for thermal curing or light curing, a high-strength FRP pipe is formed. [Applications] ● Extending the lifespan of aging or damaged sewer systems, agricultural water, industrial water pipes, etc. ● When repairs are desired only for specific areas rather than the entire span. ● When the differences between sound and deteriorated sections can be managed. ● When costs need to be kept as low as possible.

Aitec Corporation Business Introduction

We will challenge the long-life extension of the life cycle cost of concrete structures.

Concrete structures were recognized until recent years as maintenance-free. However, as reported by the media in recent years, there have been numerous cases of structural damage caused by the corrosion of steel due to chloride ions and the neutralization of concrete. Additionally, concrete structures can be damaged by alkali-silica reactions, freeze-thaw cycles, and acid rain. Furthermore, due to societal demands for increased efficiency in road transportation, the design loads for road bridges have been increased since 1993. However, many bridges continue to be used under outdated design standards. These structures often lack sufficient load-bearing capacity, and many are experiencing damage due to overloading. The myth of concrete structures as maintenance-free permanent structures has become a thing of the past. At Aitec Co., Ltd., we challenge the long-life cycle of various concrete structures that support our daily lives with the latest repair and reinforcement technologies. For more details, please contact us or download our catalog.

Reinforced Soil Wall Method RRR-C Method

Cutting soil reinforced earth wall method

The RRR method (Reinforced Railroad with Rigid Facing-Method) is a new soil retention technique (reinforced soil wall) developed as an alternative to traditional retaining wall methods, utilizing the principles of reinforced soil engineering. Traditional retaining walls are structures that, from a mechanical perspective, aim to support external forces (earth pressure) exerted by the soil through the weight of the structure and the ground reaction of the foundation, opposing the soil and embodying a philosophy of countering force with force. In contrast, the reinforced soil wall method promotes the stabilization of the soil itself by placing tensile reinforcement materials within the soil, representing a structural philosophy that seeks to coexist with the soil.
