Standard PVD Prefabricated Vertical Drain Belt
Standard PVD (Prefabricated Vertical Drain) is a high-efficiency drainage material specifically designed for the treatment of soft soil foundations; it is composed of a high-strength plastic core wrapped in a durable non-woven geotextile filter.
By vertically installing these drains into soft soil foundations—often in conjunction with surcharge preloading or vacuum preloading techniques—pore water can be rapidly expelled. This accelerates foundation consolidation and settlement, enhances bearing capacity.
PVDs are widely used in various infrastructure projects, including highway and railway roadbed construction, port and terminal development, and municipal infrastructure projects.
