Apply a second bead of anchor grout into the slot, making sure that the first bar is completely covered. Trowel away any excess grout before adding the second helical bar. This bar should reach around half the depth of the slot and be at least 10mm from the first bar. This guide aims to answer these questions and take you through how to repair lintels with helical spiral bars. Mix the powder and liquid components of WHO-60 grout and load the mixture into an applicator before pumping a bead of the specialist grout from the rear of the slots and fill them half to two thirds full. 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? As owners and creators of a growing portfolio of best in class buildings, we are very aware of the considerable part the built environment has to play in carbon emissions and waste generation. We are therefore committing to ambitious yet realistic targets to ensure that our activity is having the lowest possible impact and where possible, making a positive contribution both socially and environmentally.

Insert a second helical bar into the incision about halfway into the incision. Ensure a 10mm gap between the two bars. The best way to do this is with an inspection to appraise if there are sufficient walls ties. With a cavity wall, you should be able to carry out a visual inspection, looking between the inner and outer leaves. If you are unable to get a good view of the existing wall ties and their frequency then you canuse a metal detectoror an endoscope camera. Our Easi-Fix Helical Bars are effective at stopping structural movement and returning stability. Easi-Fix is a specialist range of structural repair products that are precision engineered, highly effective and long-lasting.

Clear all loose debris from the newly chased apertures and use clean water to ensure they are thoroughly flushed out and wet-down before installation of the grout. Wetting the masonry reduces suction of the liquid from the grout.

General builders are able to buy Twistfix helical bars in a wide range of lengths and diameters; all with improved product tolerance and consistency. Helically twisted masonry reinforcementrods have for 30 years been used in the structural repair sector of the UK building industry; but do you know whether Helifix Helibars or Twistfix bars have been used? The original Helibars were invented and patented by Twistfix Director WilliamOllis, whorecentlyre-engineered his invention. These upgraded Twistfix bars are produced with a greater degree of product consistency to improve upon the performance of the early Helifix product. Polyester or epoxy resins are brittle once set and may cause sudden breakage of the beam when overexerted; they also have a mismatch of thermal and moisture movement characteristics that makes them less effective. How do you fixhelical bars into an existing wall to form a lintel? The ties can be installed using a SDS-Plus shank hammer drill to drive and countersink the tie. The unique design of the helical tie means the tie can be easily driven into a 5.5mm pre-drilled pilot hole. The fins of the tie undercut the masonry when being driven into the substrate to provide an expansion-free anchorage that will withstand tension and compression loads.

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. 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. Helical bars are extremely versatile - they can be cut to any length and bent to form the required shape. We recommend fitting them with Easi-Fix 2C cementitious grout or the PermaCEM Anchor Grout. Helical bars are a proven way of increasing the tensile and flexural structure of masonry walls. Retaining the strong belief that our portfolio of high quality, sustainable and technologically advanced buildings are best placed to take advantage of the evolving central London commercial property market.

Helifix HeliBar Remedial Helical stainless steel reinforcing bar for masonry repair and new construction 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.

We create sustainable and inspiring workplaces which are technologically smart, rich in amenities and promote employee wellbeing. 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. 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. At Permagard, we’ve been manufacturing innovative structural repair products for over 25 years. As an independent helical bar manufacturer, we work hard to remain market leaders and ensure compliance with all standards.With the addition of a second bar, the stress forces that act on the lintel are further redistributed. The tensile strength exhibited by a lintel reinforced with a helical bar surpasses the alternatives, often many times over. With the lintel restored, you remove the risk of the lintel failing and any dangerous repercussions. Installing Helical Bars for Lintel Repairs
