Transverse & Longitudinal

Utilised on bridge decks, highways and other surface areas that may require improved drainage and or better surface traction for safety reasons.

Transverse and Longitudinal Grooving

  • Grooving improves drainage
  • Which improves traction
  • Which improves safety

The objective of grooving is to provide better drainage on the deck surface. Grooves are saw cut into the bridge deck surface transversely, or perpendicular to the direction of the traffic, after the concrete has cured. Bridge deck grooving is done by diamond blades that are ganged, or arranged at spaced intervals, on a shaft. The depth of cutting and spacing as well as the width of the diamond blades are determined by an engineered design.
