★★Notice★★★ We participated in the 5th Wakayama Prefecture Kensanpin Construction Materials Fair.★★★

There should still be expenses that can be cut. Please consult with us.

K.F. is a company that challenges various issues with the themes of environment, disaster prevention, and recycling. We handle various materials related to slopes and civil engineering, rooftop greening, and thornless lifting wire slings, among others.

• Rainwater infiltration facilities

Utilizing resources, moving towards the construction of a circular society that approaches zero emissions [Plant-Induced Spraying Work].

The plant-induced spraying method is a resource-circulating greening technique that effectively utilizes raw chips from felled trees and uprooted materials as a growth substrate. Wakayama Prefecture Ken Sanpin Registration Number H23-754 【Features of the Plant-Induced Spraying Method】 1. It allows for the effective use of felled trees and uprooted materials. 2. It has high erosion resistance and does not erode even in bare ground conditions for long periods. 3. By incorporating a specialized microbial active enzyme called "Haeru-chan," it avoids plant growth disorders caused by nitrogen starvation, decay, and the generation of harmful substances due to undecomposed chips. 4. The sponge effect due to the three-dimensional entanglement of chips is notable. Additionally, its high erosion resistance and the uneven surface of the growth substrate make it suitable for greening through natural invasion promotion (without seeding), as it facilitates the establishment of airborne seeds. *For more details, please contact us or download the PDF to view.

Acquired VE through NETIS registration! A simple spraying method framework aimed at creating green slopes and disaster prevention, preventing washout and surface erosion of slopes and embankments, and preventing surface peeling!

The Easy Shelf Method is a simplified spraying framework that can be adopted when it is determined that the conventional site-sprayed framework standards are excessive. It is positioned as a greening foundation work, preventing erosion and surface washout on slopes and embankments, as well as stabilizing the base material. We have recently obtained VE certification from NETIS. (NETIS number: KK-160021-VE) The Easy Shelf Method features a framework that is flexible and easy to construct, allowing for the preservation and restoration of green spaces. The benefits of retaining trees include environmental conservation and the reinforcement effect of tree roots, which can also help prevent avalanches. It is advisable to keep trees such as oaks, chestnuts, and beeches, while it is better to cut down planted cedars, dead trees, and trees with poor vitality. A significant feature is that the framework is a site-cast sprayed framework, using only rebar and metal fasteners (glass stands) for the framework structure, which improves workability and shortens construction time compared to conventional spraying frameworks. 【Features of Glass Stand】 - The punched steel plate structure is strong against deformation from external forces. - Reduces the occurrence of cracks after spraying. - The abundance of openings and cuts eliminates mortar edge separation, making it easy to bind and enhancing workability. - Can be stacked for easy transportation.

The Easy Shelf Method for simple spraying can be utilized as a countermeasure against the frequent short-duration heavy rains occurring recently!

The Easy Shelf Method, promoted by the National Slope Disaster Prevention Association, which is managed by K.F. Corporation, can be utilized as a countermeasure against the recent frequent short-duration heavy rains! 【Countermeasure Situations】 1. As a countermeasure against erosion and collapse of slopes due to surface water: Easy Shelf Method + Vegetation within the frame 2. As a countermeasure against sliding collapse due to infiltrating water: Easy Shelf Method + Mortar spraying within the frame 【Comparison with Precast Grid Frames】 1. All beams are continuous, increasing resistance to ground collapse. 2. Surface water can be smoothly drained. 3. It is closely attached to the ground, making it less susceptible to erosion. 4. It is expected to have a suppressive effect on surface collapse.

It's called "Sanbo" because it's three bars! It's a simple spraying method framework using three rebar!

This is a type that uses three rebar rods for the Easy Shelf method of simple spray application frame construction. The Easy Shelf method is conducted under the association system, but if you are considering joining the association in the future, it is also possible to sell it in the form of a trial construction. NETIS Registration Number: KK-160021-VE 【Simple Spray Adhesive Frame - Easy Shelf Method Sanbo Type】 1. The punched steel plate structure is designed to be strong against deformation from external forces and exhibits an extremely high holding capacity in relation to the specified rebar positions. 2. It can be stacked for transportation, improving work efficiency. For more details, please contact us or download the catalog.

• Special Construction Method

Extremely high holding capacity for the rebar position in the simple spray application method framework!

This is a glass stand type that uses four rebar rods, designed for the purpose of creating green slopes and disaster prevention, under the Easy Shelf method of simple spraying frame construction. NETIS Registration Number: KK-160021-VE **Features of the Easy Shelf Method Power Stand:** 1. The punched steel plate structure is designed to be strong against deformation from external forces, exhibiting an extremely high holding capacity relative to the specified rebar positions in the design. 2. It can be stacked for easy transport, enhancing work efficiency. **Features of the Easy Shelf Method Glass Stand:** 1. The glass stand, with its punched steel plate structure, is strong against deformation from external forces and demonstrates an extremely high holding capacity relative to the specified rebar positions in the design. 2. The outer dimensions of the glass stand are designed to ensure a cover of 40 mm at all points relative to the finished shape, helping to reduce the occurrence of cracks after spraying. 3. The glass stand features numerous openings and cuts that eliminate mortar edge cutting and facilitate easy binding, resulting in excellent workability. The glass stand can be stacked, making it easy to transport.
