TF-14 vs. Hand Forming

TF-14 has revolutionized drain trench installation and performance. Check out the differences between TF-14 and hand forming.

TF-14	Hand Forming
Creates monolithic trench walls and floor	Requires installation of keyway and waterstop at cold joint
Rail accuracy assured by precision cut foam shapes	Complex carpentry skills required to create coplanar rails
Hundreds of feet installed per day with a crew of two laborers	Two skilled carpenters average 50 feet per day
Simple wood supports used for holding sections to grade	Requires sturdy and complex wooden form work
Standard radius bottom improves hydraulic flow	Square bottom creates turbulence and deposits
Forms can be left in for jobsite safety	Open pits are hazardous and collect jobsite debris
All necessary trench components available from one source in off-the-shelf design	Three separate sources for materials create risk of dimensional inaccuracies
