Reliable Support Capacity: Settlement Control Auxiliary System 'Preload Shell Method'
Introducing a groundbreaking method for subsidence suppression by implementing preload on support structures and the ground to control sinking!
The "Preload Shell Method" is a subsidence suppression auxiliary system that integrates the ground and the support structure by setting a bag (jacket) between them and injecting non-shrink mortar into the bag, thereby ensuring reliable support capacity. The "Preload Jacket" is a bag made of seamless tubular fabric equipped with an injection port with a check valve, allowing for easy injection work due to the presence of the check valve. Additionally, the "Preload Mortar" is a premixed type of rapid-setting filling material (Denka Preload Mortar) developed for the Preload Shell Method.

basic information
【Other Features】 <Preload Jacket> - The jacket has a seamless structure without joints in the circumferential direction, ensuring stable quality. - Equipped with a check valve at the injection port, making the injection process easy. - It has water permeability and air permeability. - The injected mortar is subjected to pressurized dehydration, allowing for the formation of high-strength filling hardening material in a short time. <Preload Mortar> - By using the setting adjuster "Denka Setter D500," the curing time can be adjusted. - It has excellent fluidity and ensures high fillability. - It excels in pressurized dehydration and is non-shrinkable, demonstrating effectiveness immediately after injection. *For more details, please refer to the PDF document or feel free to contact us.*
