We all want to live on the beach or a headland and have those awesome ocean views but none of us want issues like water ingress to our basements. So this was one of the issues that builder Wes Lochrin fom Ablock Builders was seeking solutions to.
Upon consulting with Actech, he decided to use Besealed Polybar to seal the joint between the slab and walls. Furthermore, AB-Lock Builders also decided to to use a combination of Besealed Zbar Connectors and UFOs on the FRP Tielock Bars, to stop water ingress along the soil nailing bars, that were anchored into the basalt rocks.
The site foreman, Zac O'Brien, had never previously used this system before and was understandably a little apprehensive at first. He believed that by tying the Besealed Connector onto the Tielock FRP might suffice.
However, he soon realized the workings of the Besealed Sealing UFO. The UFO rubber ring works close to the connector and both together operate as a Z-Bar Water Barrier. Furthermore, it also has the swellable properties of the Polybar.
Polybar is a an rubber hydrophyllic strip which is an alternative to the popular Hydrotite. Unlike Hydrotite, Polybar is 100% expansive rubber so can be more easily mechanically fastened to the previous concrete pour. If unconstraned, Polybar can expand 400% - but when encapsulated in the concrete, Polybar will create a swelling pressure to seal the joint upon the presence of moisture.
FRP Tielock is an alternative to metal Z- bars which doesn't corrode yet has similar tensile properties to Z-bar so was able to be used to help restraint the formwork of the basment wall to the bored pieres/shotcrete walls.
The BeSealed Zbar Connectors and UFOs work on a Z-bar or Tielock bar as a replacement for a a traditional Z-bar water barrier. It has the benefits of a physical barrier, but also has the chemically expansive properties of Polybar, so any moisture that tries to travel along the Z-bar/Tielock, the UFO and Zbar Connector can create a swelling pressing to stop the moisture from passing along the bar.

Wishing all our Victorian customers a speedy return to normal activity.
A typical usage of Z bar is to act as a restraint in wall forms to stop them blowing out. Tielock is a Zbar made from FRP - Fibre Reinforced Polymer - that has equivalent physical and mechanical properties to metal Zbar but does not have any corrosion characteristics.
Tielock FRP is used predominantly in applications where waterproofing or corrosion is an issue or where access to go back and patch conduit is an issue because such as at height.
Quay Civil is constructing an underground stormwater retention tank at the new Alex Ave Public School at Schofields and used Tielock FRP bars as a screed rail support as revealed in the resultant picture above.
Matt Strickland from Quay civil explained:
“We have been using this product for a couple of years now as when we do tanks, we cannot have any rust whatsoever and use TIELOCK FRP to set up internal forms and set downs, etc. Once we strip, we cut flush or drill the bar out 10 to 20mm deep and patch. We have used this method for sewerage tanks or tanks that have chlorine and never had a problem. It is very easy as we can use the same Z Bar fittings, we have on-site to set screed rails up that is higher than a bar chair can go.”
TIELOCK FRP (Fibre Reinforced Polymer) Zbar was specially developed for formwork applications. Its high corrosion resistance, high strength, cuttability and other features offer lots of benefits for all formwork applications.
TIELOCK FRP rebars have the same thread as Z bars and can be applied with all related standard accessories. After use, FRP formwork ties can remain in concrete as one-way rebars. Special parts like cones, conduit and water stops are not necessary. Being a Fibre Reinforced Polymer It has inherent corrosion resistance and avoids rusty bleeding on concrete surfaces.
As we continue to increase our range of formwwork products, we now also have introduced our own range of F17 Plywood compliant with AS/NZS 6669 with Independent Benchmark certification.
This stock is available in all 4 branches in 2400 x 1200 x 17mm and 1800 x 1200 x 17mm.
