U-Leg
No-float U-Legs eliminate subgrade barrier penetration common with most competitors systems and the concrete anchoring slab holds the forming system firmly in place.
Adjustable Clamp
The adjustable clamp allows the formwork to be micro-adjusted once the anchoring slab is poured over the bottom of the u-legs and prevents uneven joints.
Anchor Studs
Welded concrete studs independently anchor the frame into the surrounding concrete delivering structural load transfer and maximum service life.
EPS Former
Expanded Polystyrene formers can be cut with any desired custom slope and are used to create our standard radius bottom TFX systems, or any custom shape, cast-in-place concrete trench.
Deforming Groove
The center V-shaped section aids installation alignment with the adjoining former sections. After concrete placement, the deforming "V" will break free and enables easy deconstruction of the trench.
Intrinsic Trench Sediment Control and Safety
EPS Formers ensure there are no open trenches during concrete placement and curing. Formers can support light pedestrian traffic and remain in place during construction to serve as an EPA sediment and trash control BMP (best management practice).
Cross Ties
Metal cross ties hold structural steel rails tight to the foam former for consistent horizontal spacing.
Structural Rail
Most manufacturers use sheet metal overlay rails. Our structural steel angle is independently anchored to maximize load transference into the encasement concrete.
Color Coded Labels
Color-coded labels allow easy matching with other system components.
Pin Lock Retention System
Our patented four-point pin lock system provides longitudinal and vertical grate retention designed specifically to resist dynamic loading. The non-rigid system also eliminates thermal-induced stresses that traditionally cause concrete and bolt failures in frame and cover systems.
XHD Grate System
The advanced American-made ductile iron grate design yields faster inflow rates without any sacrifice in strength and less weight for ease of handling and installation.
