Overview

 

Filter Point Linings provide erosion resistant, permeable concrete linings for structures constructed over firm subgrades and relatively low hydrostatic loads. Its double-layer fabric form is joined by interwoven filter points (drains) to form a concrete lining with a deeply cobbled appearance.

Filter Point Linings were the first type of fabric formed concrete system developed. As the use of this technology has spread worldwide, a variety of other forms have been developed to meet specific job requirements.

Application

 

Ditches, channels, canals, streams, rivers, ponds, lakes, reservoirs, marinas, and port and harbor areas.

Key Strengths

 
  • It’s relatively high coefficient of hydraulic friction helps in reducing flow velocity and wave run up.
  • The filter points provide for the relief of hydrostatic uplift pressures, increasing the system’s stability.
