The CTL system is constructed of the following parts:
The concrete chambers are specially designed to work in conjunction with the CTL plastic parts. They are always in the H-20 versions. More information of these chambers can be found on ctprecast.com
In case you would like the 3" pipes run through the total chambers you have to specify this at the time of ordering.
The plastic structure is an assembly of single injection molded parts. For each available height the parts are easily snapped together. No hardware is used for the assembly. The parts are made from ABS (Acrylonitrile Butadiene Styrene), a material that already is in use in many subsurface applications. The material will holds its lifetime integrity in our Cur-Tech application.
The design of the structure and the way it snaps together gives the assembled structure its strength and stability. Each assembly can be an endless chain of parts without losing any stability. See the Product Testing page for more information about the results of the testing.
The back parts against the concrete chambers are made to swivel. This allows any slight gaps between the plastic and concrete parts to be closed.
The top plates are designed to slide back and forth to insure a tight fit between the plastic and concrete. The plastic straps that connect to the fin tops at the front insure that the CTL system cannot be installed improperly. This is a problem with some of the flimsy proprietary systems now on the market. The strap also makes installation and backfilling a snap.
The vertical sides of the fins have pins specifically designed for the Cur-Tech systems. These pins hold the filter fabric ¼" away from the perforations to avoid any chance of clogging. This air gap also helps promote growth of the biological mat.
The approved filter fabric used to cover the plastic parts is Contech c-46nw or similar. Click here to see more information. The fabric is tightly stapled to the vertical sides of the plastic parts to make the installation easier for the installer. See the section Video & Photos for more detailed information.
