Labor is the highest cost when it comes to patching tie holes in any water tight application.
Sigma Fiberglass Ties are the most cost effective option for creating a water tight seal when combined with our
hydrophilic swelling water stops.
Traditional forming methods required using non shrink grout, plug, or patching a she bolt inner rod and creates cold joints with the surrounding concrete.
The only labor required with Sigma Ties is the labor needed to cut the tie flush to the face of the concrete.
Non Standard Wall Sections >18"
Never order a custom snap tie or have your pencil rod cat heads slip again!
If your job has concrete sections that have various non standard thickness, Sigma Fiberglass Ties give all the benefit of traditional coil rod with the ease of finishing using a fiberglass tie.
Simply cut to the desired length on site, form, strip, and cut flush to the face of the concrete.
Sigma Fiberglass ties have been used in this application on a variety of projects from Post Tension high rise project and highway traffic barriers to large mat foundations replacing traditional pencil rod.
Sigma Fiberglass Ties are common practice in architectural concrete applications. The Sigma Fiberglass Tie is cut flush to the face and blends into the surrounding board form or form lined concrete creating a seamless or tie-less wall look.
CAN YOU FIND THE TIES???
The non corrosive nature of the tie ensures there will be no unsightly rust stains for life of the wall.
If you have ever had a call back for rust stains on your concrete walls, or want your project to look like new for years to come - Sigma Fiberglass Ties are the perfect solution!
Sigma Fiberglass Ties are made from a robust Vinylester Resin and E-CR glass which is proven to have the longest term durability in the most corrosive environments found on Earth.
When walls are formed where subsequent removal of snap tie heads and patching are extremely difficult or or she bolts, taper ties, or euro rods are being used and cannot be effectively pulled, Sigma Fiberglass ties is your "GO TO"
All that is required to finish the tie is a battery powered grinder.
Further, the carpentry crew can finish the ties without the need for a subsequent finishing crew to snap, sack and patch saving all that labor and material cost.
Single Side Forming
Sigma Fiberglass Ties have been used to single side form in various applications for years.
Sigma Fiberglass Ties are epoxied anchored in lieu of drop in anchors for single side forming. Or if forming into wood one can use our Wood Lag Bolt. It is recommended to have a minimum concrete strength of 2500 psi and an embedment depth of 1.6x the length of the nuts used the other side of the tie.
Sigma Rebar Hooks are also a great option for large mat foundations to eliminate running tie dozens to hundreds of feet across the form.
High Labor Cost
Sigma Fiberglass Ties take just seconds to finish once the forms are stripped with no additional patching compound needed. There is no longer a need to sack and patch, plug and grout, or finish any other type of form tie. All you need is a battery powered angle grinder.
If you consider that the wage range of a skilled concrete carpenter with all fringes included can vary from $40 - >$80/hr depending on region and union, a water tight patch where a push cone and PVC tube was used can cost up towards $40-50/tie location after product and labor cost! Finishing cost savings is why we can say that using our ties is LESS EXPENSIVE than using metal ties!
