Helical bars are stainless steel bed joint reinforcement rods used for strengthening and stabilising masonry walls. They can be used during construction but are most often used in remedial applications.<\/p>\n
Thor Helical bars are bonded into slots cut into the wall to strap or stitch cracked brickwork. They can be used to create deep masonry beams that reinforce panels of masonry and transfer structural loads from weakened zones to areas having firm support. The bars are ideal for the structural repair and strengthening of sagging or cracked brickwork, such as may be typically caused by:<\/p>\n

It is common to find a flat or shallow arch used for carrying brickwork above an opening. The original timber frame often acts as a fortuitous lintel that adds support the arch. Such arches are sensitive to cracking due to small movements of buttressing masonry. Additionally replacement of the window frame with a uPVC unit can undermine the support and provoke masonry arch failure.<\/span><\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_3″ _builder_version=”4.18.0″ _module_preset=”default” custom_padding_tablet=”” custom_padding_phone=”|||40px|false|false” custom_padding_last_edited=”on|phone” animation_style=”fade” animation_direction=”left” animation_duration=”1500ms” animation_delay=”500ms” animation_speed_curve=”ease” global_colors_info=”{}”][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” header_2_font=”Poppins|700|||||||” header_2_text_color=”#92bf50″ header_2_font_size=”25px” header_2_line_height=”1.2em” max_width=”500px” module_alignment=”left” custom_margin=”12px|||0px|false|false” custom_margin_tablet=”12px|||0px|false|false” custom_margin_phone=”12px|||0px|false|false” custom_margin_last_edited=”on|desktop” header_2_font_size_tablet=”” header_2_font_size_phone=”30px” header_2_font_size_last_edited=”on|phone” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” text_font=”Nunito||||||||” text_text_color=”#00224f” text_font_size=”17px” text_line_height=”1.65em” max_width=”700%” max_width_tablet=”700%” max_width_phone=”700%” max_width_last_edited=”on|desktop” module_alignment=”left” custom_margin=”-18px||||false|false” custom_margin_tablet=”-15px||||false|false” custom_margin_phone=”-15px||||false|false” custom_margin_last_edited=”on|phone” global_colors_info=”{}”]<\/p>\n Cracks can appear when the differing moisture or thermal movements result in tensile stresses that exceed the tensile strength of the materials used to build the wall.

The crack stitching process delivers a practical and durable masonry repair by introducing fully concealed tension straps into the wall, strengthening fractured masonry and brickwork. Cracks in house walls aren\u2019t just unsightly; they can be warning signs of structural problems. Brickwork can crack when a build-up of stress in a wall is more than can be resisted by the masonry. Stress may result from regular thermal or moisture movement or support failure. In either case, once the brick, block or mortar cracks, the pressure is relieved. However, the fractures may compromise the wall\u2019s ability to act as a restrained composite structural unit, leaving it weak and vulnerable to further damage. Horizontally strapping or stitching the masonry at regular intervals will strengthen cracked brickwork and enhance the walls\u2019 tensile, shear and flexural capacity. Extending the stitching bars 500mm beyond the crack on each side will allow them to disperse loads and relieve point-loaded stress. It is crucial to deeply fill stepped or vertical fractures to restore compressive strength and help weatherproof the area.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” text_font=”Poppins|300|||||||” text_text_color=”#FFFFFF” text_font_size=”15px” text_line_height=”1.8em” module_alignment=”left” custom_margin=”-5px||||false|false” custom_margin_tablet=”-15px||||false|false” custom_margin_phone=”-15px||||false|false” custom_margin_last_edited=”on|phone” global_colors_info=”{}”]<\/p>\n WHO-60, a polymer-modified and non-shrink thixotropic cement-based grout, bonds the twisted bars into slots pre-cut across the fracture to strap the brickwork on either side.

Helical reinforcement bars can be pre-bent at ninety degrees to form concealed straps for stitching cracks at a corner of a building. Alternatively, installing heavy-duty drive pins can reinforce external corners by tying flanking walls at regular intervals. Vertical cracks are common at the corners of masonry buildings. These fractures can occur for various reasons, including thermal\/ moisture movement. Perpendicular walls may expand towards an external corner, causing rotation of the brickwork and eventual cracking in the masonry near the junction. Alternatively, fractures can occur because of differential movements in a wall, such as a bulging flank wall meeting a straight and stable corner.<\/p>\n [\/et_pb_text][et_pb_button button_url=”@ET-DC@eyJkeW5hbWljIjp0cnVlLCJjb250ZW50IjoicG9zdF9saW5rX3VybF9wYWdlIiwic2V0dGluZ3MiOnsicG9zdF9pZCI6IjM0NzAifX0=@” button_text=”CONTACT US” _builder_version=”4.16″ _dynamic_attributes=”button_url” _module_preset=”default” custom_button=”on” button_text_size=”16px” button_text_color=”#FFFFFF” button_bg_color=”#92bf50″ button_border_width=”0px” button_border_color=”#47a145″ button_border_radius=”2.9px” button_letter_spacing=”0px” button_font=”Barlow|600|||||||” button_use_icon=”off” custom_margin=”30px||37px||false|false” custom_margin_tablet=”” custom_margin_phone=”” custom_margin_last_edited=”on|desktop” custom_padding=”15px|35px|16px|35px|false|true” global_colors_info=”{}” button_text_color__hover_enabled=”on|hover” button_text_color__hover=”#000000″ button_bg_color__hover_enabled=”on|hover” button_bg_color__hover=”#FFFFFF” button_bg_enable_color__hover=”on” button_border_color__hover_enabled=”on|hover” button_border_color__hover=”#FFFFFF” button_letter_spacing__hover_enabled=”on|desktop” button_letter_spacing__hover=”0px”][\/et_pb_button][\/et_pb_column][et_pb_column type=”2_5″ _builder_version=”4.17.4″ _module_preset=”default” custom_padding=”||||false|false” custom_padding_tablet=”||||false|false” custom_padding_phone=”|||40px|false|false” custom_padding_last_edited=”on|phone” animation_style=”slide” animation_direction=”left” animation_duration=”1500ms” animation_delay=”500ms” animation_speed_curve=”ease” global_colors_info=”{}”][et_pb_image src=”https:\/\/www.ebmwales.co.uk\/wp-content\/uploads\/2022\/10\/corner-image-1.jpg” title_text=”corner image” _builder_version=”4.18.0″ _module_preset=”default” width=”92%” width_tablet=”92%” width_phone=”92%” width_last_edited=”on|desktop” custom_margin=”1vw||||false|false” custom_margin_tablet=”1vw||||false|false” custom_margin_phone=”1vw||||false|false” custom_margin_last_edited=”on|desktop” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.18.0″ _module_preset=”default” background_color=”#8dc63f” background_color_gradient_direction=”270deg” background_enable_image=”off” custom_padding=”4px||0px||false|” top_divider_height=”36px” top_divider_flip=”vertical” global_colors_info=”{}”][et_pb_row column_structure=”1_2,1_2″ use_custom_gutter=”on” gutter_width=”2″ make_equal=”on” _builder_version=”4.18.0″ _module_preset=”default” width=”90%” width_tablet=”90%” width_phone=”90%” width_last_edited=”on|tablet” max_width=”100%” max_width_tablet=”90%” max_width_phone=”90%” max_width_last_edited=”on|desktop” custom_margin=”15px||||false|false” custom_margin_tablet=”15px||||false|false” custom_margin_phone=”15px||||false|false” custom_margin_last_edited=”on|desktop” custom_padding=”0px||60px||false|false” global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” header_3_font=”Barlow|700|||||||” header_3_text_align=”left” header_3_text_color=”#FFFFFF” header_3_font_size=”28px” header_3_line_height=”1.3em” width=”38%” width_tablet=”” width_phone=”” width_last_edited=”on|desktop” module_alignment=”left” custom_margin=”40px||||false|false” custom_margin_tablet=”” custom_margin_phone=”” custom_margin_last_edited=”on|desktop” header_3_font_size_tablet=”” header_3_font_size_phone=”30px” header_3_font_size_last_edited=”on|phone” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” text_font=”Poppins|300|||||||” text_text_color=”#FFFFFF” text_font_size=”15px” text_line_height=”1.8em” module_alignment=”left” custom_margin=”-10px||||false|false” custom_margin_tablet=”-15px||||false|false” custom_margin_phone=”-15px||||false|false” custom_margin_last_edited=”on|phone” global_colors_info=”{}”]<\/p>\n A series of helical bars, bent at a right angle, are bonded into slots with WHO-60 polymer modified grout.

Two parallel layers of bed joint reinforcement, each layer containing a pair of helical bars, represent a brick beam\u2019s upper and lower flanges. The deep masonry beams can span areas of masonry failure, redistribute applied loads, and enhance the wall\u2019s tensile, shear, and flexural capacity. Non-reinforced masonry panels are strong in compression but comparatively weak in shear and tension loads resistance. Walls can deflect and crack when subjected to increased loads and stresses. Such stresses may be induced by; localised ground movement\/ subsidence, lintel failure or moisture\/ temperature variations. Reinforced masonry has greater resistance to shear and tension loads as ductile steel reinforcement enhances it.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_3″ _builder_version=”4.18.0″ _module_preset=”default” custom_padding_tablet=”” custom_padding_phone=”|||40px|false|false” custom_padding_last_edited=”on|phone” animation_style=”fade” animation_direction=”left” animation_duration=”1500ms” animation_delay=”500ms” animation_speed_curve=”ease” global_colors_info=”{}”][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” text_font=”Nunito||||||||” text_text_color=”#00224f” text_font_size=”17px” text_line_height=”1.65em” max_width=”700%” max_width_tablet=”700%” max_width_phone=”700%” max_width_last_edited=”on|desktop” module_alignment=”left” custom_margin=”-18px||||false|false” custom_margin_tablet=”-15px||||false|false” custom_margin_phone=”-15px||||false|false” custom_margin_last_edited=”on|phone” global_colors_info=”{}”]<\/p>\n Reinforced brick masonry can strengthen masonry wherever it has lost its load-bearing capacity. It is commonly used to span areas of localised ground movement to alleviate the need for partial underpinning. In other instances, it can span between concrete pads or piles to reduce the cost of subsidence repairs. Bed joint reinforcement can also span window openings, strap external corners, stitch cracks, increase resistance to wind loading, and extend the centres of movement joints. An engineer should establish span and applied-loading to design a retrofit system to form effective deep masonry beams in existing walls. Using load tables from the BRE report on creating reinforced brick beams using Thor Helical bars, the specifier can determine the vertical distance between each pair of bars to establish the depth of the beam.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_3″ _builder_version=”4.18.0″ _module_preset=”default” custom_padding_tablet=”” custom_padding_phone=”|||40px|false|false” custom_padding_last_edited=”on|phone” animation_style=”fade” animation_direction=”left” animation_duration=”1500ms” animation_delay=”500ms” animation_speed_curve=”ease” global_colors_info=”{}”][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” text_font=”Nunito||||||||” text_text_color=”#00224f” text_font_size=”17px” text_line_height=”1.65em” max_width=”700%” max_width_tablet=”700%” max_width_phone=”700%” max_width_last_edited=”on|desktop” module_alignment=”left” custom_margin=”-18px||||false|false” custom_margin_tablet=”-15px||||false|false” custom_margin_phone=”-15px||||false|false” custom_margin_last_edited=”on|phone” global_colors_info=”{}”]<\/p>\n Forming masonry beams with helical bars can form part of a more comprehensive masonry repair scheme, including additional lateral and vertical restraint reinforcement. For example, retrofit masonry reinforcement systems and other retrofitted products for tying walls add restraint by securing reinforced masonry to timber floors or reconnecting external walls to internal walls at weak junctions.<\/span><\/p>\n [\/et_pb_text][et_pb_button

Thor Helical bars above door and window openings is a quick and easy way of creating or repairing brick arch lintels in buildings. The high tensile stainless steel bars utilise existing brickwork to form a reinforced brick lintel over a flat soldier course or curved masonry arch. Lintel failure occurs for a variety of reasons. Shallow or flat brick arches can fail due to inadequate buttressing on either side of the arch, concrete lintels tend to rotate, whist timber and steel lintels may degrade over time as rot or corrosion sets in. It is not uncommon for old timber or steel window frame to form a fortuitous lintel, which helps to support the brickwork above. When replacing these load-bearing windows and doors with non-structural uPVC units, support from the fortuitous lintel is lost, and the masonry may begin to crack as the brickwork sags.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_3″ _builder_version=”4.18.0″ _module_preset=”default” custom_padding_tablet=”” custom_padding_phone=”|||40px|false|false” custom_padding_last_edited=”on|phone” animation_style=”fade” animation_direction=”left” animation_duration=”1500ms” animation_delay=”500ms” animation_speed_curve=”ease” global_colors_info=”{}”][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” text_font=”Nunito||||||||” text_text_color=”#00224f” text_font_size=”17px” text_line_height=”1.65em” max_width=”700%” max_width_tablet=”700%” max_width_phone=”700%” max_width_last_edited=”on|desktop” module_alignment=”left” custom_margin=”-17px||||false|false” custom_margin_tablet=”-15px||||false|false” custom_margin_phone=”-15px||||false|false” custom_margin_last_edited=”on|phone” global_colors_info=”{}”]<\/p>\n Thor Helical bars have a long history of reinforcing and repairing brick arch lintels over openings. A section of the mortar bed is cut out immediately above the existing arch or lintel, and another is cut out further up the wall. The slots extend at least 500mm on either side of the opening. WHO-60, a polymer-modified cement-based grout, bonds a pair of spiral bars into each channel. The grout cures rapidly to create reinforced layers representing a reinforced brick beam\u2019s upper and lower flanges. The brick beam supports the masonry above and spreads the structural loads.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_3″ _builder_version=”4.18.0″ _module_preset=”default” custom_padding_tablet=”” custom_padding_phone=”|||40px|false|false” custom_padding_last_edited=”on|phone” animation_style=”fade” animation_direction=”left” animation_duration=”1500ms” animation_delay=”500ms” animation_speed_curve=”ease” global_colors_info=”{}”][et_pb_text _builder_version=”4.18.0″ _module_preset=”default” text_font=”Nunito||||||||” text_text_color=”#00224f” text_font_size=”17px” text_line_height=”1.65em” max_width=”700%” max_width_tablet=”700%” max_width_phone=”700%” max_width_last_edited=”on|desktop” module_alignment=”left” custom_margin=”-18px||||false|false” custom_margin_tablet=”-15px||||false|false” custom_margin_phone=”-15px||||false|false” custom_margin_last_edited=”on|phone” global_colors_info=”{}”]<\/p>\n The Building Research Establishment has carried out independent testing on this brick lintel system. The BRE has issued a report on creating or repairing brick arch lintels in buildings using Thor Helical bars. The information includes load tables for the masonry beams given the width of the span and the depth of brickwork between the top and bottom layers of reinforcement. Where lintels sag, a user may supplement this method of strengthening and repairing brick arch lintels by introducing remedial pinning ties installed vertically up through the arch and into the reinforced zone of the masonry beam. Where cracks have appeared above an opening, shorter helical bars can stitch them, and crack-repair mortar or a low-viscosity epoxy resin can fill the fracture.<\/p>\n
