Water measures for existing structures in scenic areas! Construction methods suitable for extending the lifespan of structures.
No need to demolish existing structures without compromising the landscape! This construction method is suitable for the maintenance and preservation of openings, gaps, looseness, sagging, suction, subsidence, voids, and more.
The "Tosui CON Filling Method," suitable for measures to extend the lifespan of structures, is a construction method aimed at preserving and maintaining existing structures while maintaining landscape formation. In response to the aging of stone masonry and stone walls in riverbanks, waterways, and residential areas, a plant is set up on-site to inject and fill with Tosui CON (aggregate, cement, water, B.CON + S), which excels in permeability, strength, durability, and workability from joints and cracks. This helps maintain the stability of the stone masonry and suppresses piping phenomena by draining water from the joints. 【Construction Example】 Purpose: Water measures for existing structures in landscape areas Preservation and maintenance of openings, gaps, looseness, bulging, suction, subsidence, voids, etc. Proposal: Tosui CON Filling Method Features: - Does not compromise the landscape - Prevents backfill erosion - No traffic restrictions required - No need for demolition of existing structures - No noise or vibration - Suitable for water measures *For more details, please refer to the PDF download or contact us.

basic information
[Permeable Concrete Permeability Test (Constant Water Level)] This test was conducted in accordance with the constant water level method established by the Soil Mechanics Society. However, to verify and confirm whether the infiltration flow follows Darcy's law, the hydraulic gradient was varied, and the flow velocity was measured and graphed. To enhance the reliability of the permeability coefficient, a simple regression analysis was performed based on the relationship between the hydraulic gradient and flow velocity within the laminar flow region (i≦0.1, including the theoretical values of hydraulic gradient i=0 and flow velocity v=0). Permeability coefficient: K15 = 2.22 × 10^-1 cm/sec As stated above, the management standard for the permeability coefficient (1.00 × 10^-1 ≦ K15) is satisfied.
