Pack of 10 x 6mm x 1 Metre Stainless Steel HELICAL Bars for Repairing Masonry Walls

Product Information

We have broken down the installation into simple easy to follow steps. The installation method outlined below applies to both window and door lintels. It is strongly recommended that you install helical bars at two levels above the failed lintel. The Easi-Fix Helical Drive Tie has been labelled as the more reliable and faster way to tie facades together. The ties can also be installed through cavity wall insulation, providing high strength and flexibility. Although the job may sound expensive, the installations costs are relatively low. In this article, we're sharing read on for more information on the several types of helical bars available and their different purposes. Below are the most common helical bars used for construction and structural repair purposes. What are Helical Spiral Bars? Helical bars are buried into slots made in the wall surface. The slots are typically orientated horizontally along the face of the wall and the bars are bonded to the masonry using a high performance polymer modified grout. What are the applications for helical bars?

Helical bars have great axial strength when grouted into walls. They are able to spread loads and accommodate natural and cyclical movements within a building whilst holding the components firmly together.The reinforcing bars are generally concealed within mortar beds to disguise installation. Once correctly installed, helically twisted bars provide strong reinforcement to fortify lintels and give a property a new lease of life. Installation is complete in seven easy steps, which are listed below. The Helifix HeliBar is a helical stainless steel reinforcing bar, with substantial tensile properties, used for strengthening and stabilising masonry in both new build and remedial situations.Push a helical bar into the incision about three-quarters deep. Ensure the grout encapsulates it and compress any grout that has been displaced. Sometimes lintels don’t exist in the first place. When there isn’t a lintel above a window, it usually means the masonry was built directly onto the window frames. In this instance you can create a new lintel using helical bars. You can do this by installing two levels of helical bars using the method outlined above.

Insert a second helical bar into the incision about halfway into the incision. Ensure a 10mm gap between the two bars. Helical bars when used for lintel repairs are available in three and seven metre lengths. These longer lengths allow the bars to extend beyond the window or door by the required 500mm. You can also cut the longer lengths to the exact size required. We recommend thixotropic WHO60 ®, which is a cement-based grout featuring added polymers.The BRE Load Tables are specific to the proprietary helical bars tested and bonded into walls with this purpose-made mortar. Shrink-compensated, the grout effortlessly bonds the bars to the masonry, setting in and around the deep troughs of the helix and delivering compressive strength combined with some flexibility, which safeguards against sudden failures when overloaded.Twistfix only supplies helicalbars produced with this advanced engineering.The upgraded bars areproduced in the UK's only manufacturing facility that, under one roof,takes in round wire and sends out finished helical products. Other manufacturers merely part-process pre-shaped wire thathas been cold roll-profiledby a third party. Helical spiral bars also provide extra strength in footings, parapets and retaining walls. They can be used during new construction or remedial work in existing buildings. Where timber lintels are used, often in older properties, you are at risk from wood rot (wet and dry) as well as wood boring beetles. This can affect the structural integrity of the timber and mean that need you to replace or repair them using helical spiral bars as outlined in this guide. The primary component of a masonry stitching kit is the helical stitching bars. These bars are often made of stainless steel and are twisted - helical refers to a spiral shape - to provide extra strength and flexibility.
