Are you struggling with cost issues due to unintended flow of fresh concrete into underground cavities, drainage ditches, or air raid shelter remnants during the construction of cast-in-place concrete piles, resulting in incomplete pours or significant overages of planned quantities? The Resophon Pier Method is a patented technique that physically prevents excessive outflow of fresh concrete by attaching a permeable chemical fiber net to the rebar cage. It minimizes unnecessary material costs associated with concrete outflow and ensures that the finished shape and quality are maintained as designed. It is compatible with a wide range of construction methods, such as earth drilling and all-casing methods, and can be easily implemented on-site without the need for additional special machinery. It helps avoid unexpected outflow risks and contributes to optimizing construction costs. 【Features】 - Prevents outflow of fresh concrete into underground cavities and mine remnants - Reduces excessive pouring amounts and material costs - Compatible with earth drilling and all-casing methods - Improved workability with simple installation of the net *For more details and case studies, please check "Download the Catalog."

In construction sites with nearby underground drainage systems or existing waterways, there is always a risk that the poured concrete will leak into the drainage, causing blockages in the waterways or leading to runoff accidents downstream. The Resophon Pier method is a construction technique that minimizes concrete leakage by attaching a specialized mesh fabric (made of polyethylene) to the outside of the rebar cage. This effectively prevents outflow troubles to nearby structures and drainage systems, achieving both environmental consideration for natural discharge points and safe construction simultaneously. We provide a solution that dramatically reduces construction risks and neighborhood troubles in urban areas and waterfront projects, particularly in public works involving close proximity construction. 【Features】 ■ Guards against concrete leakage into nearby drainage systems and waterways ■ Prevents blockages in waterways and environmental pollution at natural discharge points ■ Reliable shielding effect with polyethylene mesh fabric ■ Significantly reduces environmental troubles in close proximity construction *For details and site achievements, please check "Download Catalog."

In sites where the backfill after the removal of existing piles and the fluidized treatment soil layers are in close proximity, there are challenges such as ground collapse during excavation, leading to the inflow of uncured filling materials into the borehole, or the formation of irregularly shaped new piles connected to the existing ones. The Resophon Pier Method employs a high-strength net surrounding the rebar cage, which effectively absorbs lateral pressure and ground collapse, strongly maintaining the proper shape of the new piles. This method significantly streamlines the backfilling process after removal and the complex protection procedures, resolving issues related to design strength deficiencies and failure to meet shape management standards due to irregularities. Experiments have confirmed that the impact on surface friction is equivalent, achieving high reliability in construction on demolition sites in narrow areas and redevelopment projects. **Features** - Prevents ground collapse and inflow of uncured materials at the site of existing pile removal - Prevents the new piles from becoming irregularly shaped and maintains their form - Maintains surface friction equivalent to that of standard concrete piles - Suitable for pile quality management in demolition and redevelopment sites *Please check the technical data and test results by downloading the catalog.*

When constructing place-driven piles in peat layers (peat bogs) with an N value of 0 or in soft humus layers, the lateral pressure from the fresh concrete can cause significant bulging (lateral expansion), leading to distortion of the pile shape and a sharp increase in concrete consumption. The Resophon Pier Method minimizes unnecessary concrete protrusion in ultra-soft ground by attaching a lightweight and durable permeable net to the rebar cage. It enhances the accuracy of the calculation for the driving position, maintains the shape, and optimizes concrete usage. This reliable technology, recognized as a NETIS registered technology (KT-240066-A), strongly supports the assurance of pile quality and economical construction in extremely poor ground conditions. 【Features】 ■ Suppresses bulging in peat layers and humus layers with an N value of 0 ■ Optimizes concrete placement volume and improves cost-effectiveness ■ Obtained NETIS registration technology (KT-240066-A) ■ Achieves reliable shape and quality control even in soft ground *Please check "Download Catalog" for construction results and procedures.

The "Resophon Pier Method" is a construction technique that suppresses the outflow of concrete into voids such as abandoned coal mines, air raid shelters, and underground drainage, thereby reducing material waste and construction costs, while also contributing to the quality assurance of piles. It involves covering the rebar cage with a dedicated "Resophon Net." Joint research with Kyoto University has shown that even when the net is attached, the surface friction force is comparable to that of standard concrete piles (approximately 0.9 to 1.1 times), and methods are available to reduce it to about 0.9 times, which is equivalent or on the safe side. This is a NETIS registered technology that can be widely applied, ranging from site-cast pile methods such as earth drills, reverse, and all-casing to underground continuous wall methods. 【Features】 ■ Suppresses unnecessary concrete outflow, allowing for reductions in material waste and construction costs ■ Contributes to ensuring the shape of piles and the quality of concrete ■ Lightweight polyethylene net makes attachment to the rebar cage easy ■ NETIS registered (Registration number: KT-240066-A), Patent No. 3963921 *For more details, please refer to the materials.
