Tetra™ LP Block
When a lower profile block is called for, consider the Tetra™ LP Block. You get all the advantages of the U Block, plus:
- Lower profile affords more media depth and height for air/water backwash
- 6" wider profile means fewer blocks, fewer joints, and less grout
- Can be cut in half lengthwise to avoid grouting space that will not accommodate a full width block
- Features Grout-Grip strip for greater installation strength
SAVAGE PLATE®
An underdrain installation is only as good as its media retention plate. Lightweight and easy to install, the SAVAGE PLATE® is a high-density polyethylene porous plate.
- Removable for inspection
- Compatible with water treatment chemicals
- Provides uniform flow distribution at a headloss equivalent to or less than gravel
- Eliminates gravel layer allowing additional media and/or longer filter runs
