Ace Sand Method: Mortar for Underwater Placement

Possible underwater placement with the incorporation of bentonite! Mortar for underwater placement using locally generated soil.

The "Ace Sand Method" is a construction technique that utilizes locally generated soil (especially sandy soil), river sand, recycled sand, and improved soil, adding a solidifying agent and water to fluidize it, and then pumping it to areas where backfilling is difficult. At that time, pumping sand with a concrete pump was revolutionary, as it made backfilling in narrow spaces easy, ensured sufficient water tightness, and contributed to shortening construction periods, attracting significant attention. To prevent material separation underwater, water-resistant agents and bentonite were mixed to enable underwater placement. *For more details, please refer to the PDF materials or feel free to contact us.*
