Fiberglass Ties+Board Form
Board formed concrete is an increasingly popular look when pouring an exposed wall. It’s achieved by forming with rough sawn or dimensional lumber, leaving the grain and knotty features of the wood as impressions in the concrete. Its an outstanding natural looking wall.
Fiberglass ties are ideal for board form work — they blend in and will never rust, which means NO STAINING, and because the ties are ground flush with the wall there is NO PATCHING.
If you own or rent steel-ply panels, pouring a board form wall with fiberglass ties is incredibly easy. See below for a step by step guide.
Application Guide
INSTALLATION
1.) Fasten boards to formwork
Set up one side of formwork (the one where the board form will be attached) and nail boards to wall.
2.) Drill slots
Drill or route slots in at the intended tie locations. Slots should be 5/16” wide and 7/8” tall to allow the loop to comfortably slide through.
3.) Feed ties through
Pass ties through slots and wedge bolt in place.
4.) Stage second side
Stage the other side of your formwork.
5.) Spay with form release
Spray boards and forms using a high quality, reactive form release.
6.) Pour concrete
Pour and vibrate the wall based on recommended pour rate for a 3000 lb, heavy duty loop tie.
STRIPPING
Cut the tie back
After stripping the panels and pulling the boards off the wall you will be left with the loop end of the tie sticking out. Grind or cut the tie flush using either an angle grinder with a diamond cutter or an oscillating multi-tool.
