Sewer Composite Manhole Rehabilitation Method "Eba Sheet Method"

Long-lasting corrosion-resistant manholes! A sewer composite manhole rehabilitation method that achieves material savings.

The "Evashito Method" is a composite manhole rehabilitation technique that involves attaching an "FRP sheet" to the inner wall of an existing manhole that has advanced corrosion, using an expansion frame, and filling the gap between the sheet and the existing manhole with mortar. The backside treatment of the FRP sheet creates a rough surface with the adhered silica sand, enhancing the adhesion strength with the filling material and achieving a complete integration with the existing manhole, resulting in strong durability. No heavy machinery is required, and no special skills are needed, allowing for construction in a small road occupancy area. By utilizing the existing manhole, material savings are achieved, along with a reduction in construction time, resulting in excellent cost-effectiveness. 【Features】 ■ High quality ■ High speed ■ Low cost ■ Can be constructed in a small road occupancy area ■ Achieves material savings by utilizing existing manholes *For more details, please refer to the PDF document or feel free to contact us.
