Concrete setting delay agent "Dispalite" (joint treatment agent)

Concrete setting delay agent "Dispalite" (joint treatment agent)

Registered in the Ministry of Land, Infrastructure, Transport and Tourism's "New Technology Information Provision System"! Design Comparison Target Technology

Dispalite is a concrete joint treatment agent and setting retarder that provides excellent uniformity and high-quality joint surfaces, ensuring safe and reliable results. The standard type "Dispalite CR" for horizontal joint treatment delays the setting of concrete by spraying the concentrated solution when the bleeding water has receded after concrete placement, allowing for efficient and effective joint treatment. Additionally, we offer Dispalite ER, which further extends the setting delay time, and Dispalite DV, designed for vertical concrete joints. 【Features】 ○ Uniformity → Achieves a high-quality joint surface that is uniform and free of inconsistencies. ○ Reliability → Significantly alleviates time constraints during work, enabling efficient and reliable joint treatment operations. ○ Safety → No adverse effects on concrete or reinforcing steel. ○ Former NETIS registration number: No. KK-990050-V certified as "Design Comparison Target Technology" (registration ended). For more details, please contact us or download the catalog.

Introduction to Slit Engine Technology: Reinforced Soil Retaining Wall "Steel Slit Wall Method"

Introduction to Slit Engine Technology: Reinforced Soil Retaining Wall "Steel Slit Wall Method"

The wall is made of steel, so its demand is not affected by the supply situation of concrete.

The "Steel Slit Wall Method" is a reinforced earth retaining wall construction method that pursues enhanced durability, safety, and disaster mitigation through the use of steel wall materials and chain reinforcement. Since the wall surface is made of steel, it is rich in strength and flexibility, and by utilizing the friction resistance and workability provided by the chain reinforcement, we are confident that this method will be effective in future civil engineering projects, especially in reconstruction sites following the Great East Japan Earthquake, where a shortage of concrete is anticipated. 【Features】 ○ Lightweight → The wall material weighs 20 kg per sheet, and the chain is easy to carry in bags. ○ Strong → The steel wall surface is fully integrated, providing high rigidity. ○ Fast → Standard construction area of about 30 m² per day, no concrete foundation required, and easy assembly. ○ Trademark registration No. 4880758 (frame type) ○ NETIS registration No. KK-120014-A (mesh type) For more details, please contact us or download the catalog.

Large Block Retaining Wall "SP Block III-1, 2, 3"

Large Block Retaining Wall "SP Block III-1, 2, 3"

Speed Soil Retention Prefabricated Method SP Block III-1, III-2, III-3

Each block of "SP Block III-1, III-2, III-3" has the form of a cantilever retaining wall on its own, preventing the top wall from toppling over, while the backfill of crushed stone or concrete placed on the base slab acts as a counterweight for stability. The Speed Soil Retention Prefabricated Method involves stacking products that have enlarged face and control lengths of conventional block walls into a box shape, applying backfilling (behind filling) work, and constructing to a specified height. 【Features】 ○ Each block functions as a cantilever retaining wall ○ Adjacent wall bodies are connected with bolts through a single hole on both sides of the cantilever ○ Drainage holes are provided at a rate of one per approximately 1m², allowing drainage for each layer of blocks ○ NETIS registration KK-010046-V For more details, please contact us or download the catalog.

Flexible cantilever retaining wall "Free Wall (Box-type Retaining Wall)"

Flexible cantilever retaining wall "Free Wall (Box-type Retaining Wall)"

Retaining wall constructed with precast products and single-sized crushed stone.

■NETIS CB-040038-A (Publication period ended) ■This is a retaining wall that obtained construction technology examination certification from the Public Interest Incorporated Foundation Civil Engineering Research Center in March 2004. ■Due to its flexible structure, it reduces the stress generated by the slight movement of the retaining wall against soil pressure during an earthquake, thereby suppressing cracking and collapse of the wall. ■The ground reaction force during an earthquake is relatively small, and it demonstrates adaptability to differential settlement of the foundation ground and backfill soil, maintaining the overall safety of the retaining wall. ■The layer of single-sized crushed stone has extremely high drainage capacity, which inevitably stabilizes the backfill soil. ■Since there is almost no work involving rebar, concrete, or formwork at the construction site, significant reductions in construction time and improvements in cost-effectiveness can be achieved. ■The product can be used in a reversed manner, making it easy to construct curves. ■The stepped shape has a three-dimensional aesthetic appeal, and it is possible to consider ecosystem preservation through planting and natural greening using each small step. ■The maximum wall height in construction achievements is 21m. (Please consult us regarding applicable heights) *For more details, please download the materials or contact us through our company website.*

Precast concrete products for road use - precast guardrail foundation

Precast concrete products for road use - precast guardrail foundation

Excellent workability and outstanding in reducing construction time.

When installing guardrails using conventional methods, issues arise such as the tensile stress of the vertical wall exceeding the allowable value and instability against overturning. As countermeasures for conventional methods, increasing the thickness of the members or adding reinforcement for stress, and widening the base plate for overturning are some of the solutions. To address these issues, we have developed an independent protective fence foundation called "Precast Guardrail Foundation."
