”Sun Geo Cube”
-Rainwater harvesting and infiltration system -
Sun Geo Cube is a rainwater harvesting and infiltration system material that increases the strength of facilities with its mating structure.
This is a system material for constructing rainwater storage and infiltration facilities that are required to be installed in accordance with the Law Concerning Measures to Prevent Flood Damage to Specified Urban Rivers.
By temporarily storing and infiltrating rainwater underground, they play an important role in controlling rainwater runoff and improving water utilization. Land can be effectively utilized by burying it under parking lots of shopping centers and distribution facilities, parks, schoolyards, sidewalks, and street trees.

Feature
High strength
The block members are lightweight and have high strength due to their mating structure. Block and cave materials work effectively as strength members.
Vertical load corresponds to T25 (soil cover thickness: 50 cm or more, after pavement)
50-year long-term durability and earthquake resistance (Level 2)
The product has obtained Level 2 seismic performance by horizontal alternating load test. The product satisfies chemical durability after 50 years by satisfying tertiary creep.
High porosity
The high porosity of 96% allows for volume savings in the dimensions of the storage and infiltration facility.
Easy installation & shortened construction period
The main block weighs only about 2 kg/piece and can be assembled by hand. Also, the curing period required for the construction of concrete storage facilities is no longer necessary, leading to a shorter construction period.
Compact transportation
The stackable design allows for compact storage and transportation. Special suspension belts allow pallet-less transport.
Mud and sand diffusion prevention wall system
We are also fully prepared for guerrilla downpours. Do you have any of the following concerns?
Muddy sand doesn’t go into the facility?
What happens if muddy water gets in?
Does the permeable sheet cause clogging?
This revolutionary system is designed to prevent the spreading of mud and sand inflow, making it easy to clean up and visually manage the space.
Material Specifications
Three types of systems can be constructed by combining Sun Geo Cube and sheets.
Storage system
Rainwater can be temporarily stored by laying impervious sheets (t=1.5 mm) on the bottom and wall surfaces. The impervious sheet is protected by a protective sheet.
Infiltration system
By laying protective permeable sheets on the bottom, top and wall surfaces, rainwater is temporarily stored and runoff is controlled. Rainwater gradually percolates into the soil through protective permeable sheets.
Irrigation system
By making the lower part of the structure a constant water storage type, a certain amount of stored water can be secured and utilized. The upper portion of the structure serves as a storage facility.
