The Award Winning Brick Brace Safety System. Reading is essential to gain further masonry alterations knowledge. When knowing every task is different, each project will be planned upon its own merit and carried out safely by using a combination/variety of temporary masonry support equipment most suitable of which also stabilises & supports all of the masonry and gives the correct fitting/working access. Different scenario's require far more preparation than only using Acrow props fitted with tongued attachments as they do not offer.
The correct fitting work space for every task without dangerously overloading the structure above. We created the Brick Brace to provide further options, to counter act all of the hidden problems of eccentrically propping.
To make alterations more controllable, safer and easier during the task and to ensure future generations are taught correctly. To Brace masonry, the force required upon the safety tools is estimated at 700N, for a safety factor of x 3 the force is 2.1kN.A recommended torque of 40Nm produces a force of 3.28kN which is more than adequate even allowing for some fall off in force as the tool beds in. This torque is also readily achievable on site and was also used in the test via a ratchet spanner. It also provides a force well below that to crush the end faces of the brick. When bricks were removed from below there was no distress whatsoever, no visible movement or cracking which suggested that the calculations are very reasonable. The stability & lateral strength of masonry is unpredictable & varies upon every structure of which depends on the length of the opening, the mortar mix, the age & the quality of the masonry.
All existing propping methods rely on the unknown variable lateral strength of the masonry to work safely. The fully tested Brick Brace safety tool increases the unknown variable strength of masonry by creating a force of 40Nm which through testing is proven to be strong and stable enough to prevent collapse. A tongued prop attachment was designed in the mid 1980s when openings were smaller and a cavity only 50mm but due to changes in construction design a typical cavity has now doubled to 100mm and 150mm+ upon newer properties for further thermal value and open plan living accommodation has also vastly increased the opening and steel sizes within a typical residential extension.
The safe working load is severely compromised by over extending even further from the wall to gain more fitting space when a. Ttempting tasks which require longer and wider steels with welded top/bottom plates for wider cavities when still only using the out of date tongued prop attachment. We have studied temporary masonry support for many years, more than anyone before us.

Superior results and time saved. The main cause of collapse during masonry alterations is overloading due to underestimating the weight of the load & over extending Acrow props fitted with tongued prop attachments from the wall to either avoid internal 1st floor wall damage or attempting to gain more fitting work space as over extending greatly affects the Acrow props safe working load. The Maximum Safe Working Loads. An Acrow prop, 3,400Kg.An Acrow prop used within the props and needles method, 1,700Kg. When fitted with a tongued prop attachment an Acrow props safe working load is severely reduced by at least 90%, from 3,400kg down to the maximum 340kg and can even reduce down to 0kg of which depends on the size & the working height of the Acrow prop, how plumb, how tightly fitted and how far the Acrow prop is positioned from the centre of the wall. To maintain the maximum 340kg safe working load the tongue must fully penetrate the internal skin when supporting a cavity wall, as seen in the drawing below. After taking the time to read and understand what the Brick Brace has to offer, I can now appreciate the impact this system can have on improving the safety of structural alterations. After all, structural alterations are the only general construction based procedures where NO training or advice is offered to any tradesman. For me, Brick Brace is not just a product; it has provided an understanding of the task, with clear guidance on the limitations of all the equipment. I also received very helpful advice and instructions from the guys at brick brace regarding my own project. I challenge you all to find another company so invested in your own safety when it comes to structural alterations! EXCELLENT, A+, GREAT, 100% POSITIVE, 5 STARS.

What is the nature of the task, is it remedial works or fitting a permanent support?Is it forming a new opening or increasing the size of an existing opening? Is the opening in a 4single skin of masonry, two skins or even more? Is the opening in the outer or the inner leaf of a cavity wall or in both? What is the age and condition of the masonry and what is the masonry material? What design (cavity or solid)? What is the size of the cavity? What thickness is the wall? Which bond is the masonry and which mortar mix, cement or lime? What are the existing ceiling heights?
What are the size and direction of floor/joists, are they load bearing onto the wall or are they non load bearing? Does the existing floor impede the internal fitting access? What height is the opening, ground floor, first floor or higher?Is a permanent support fitted underneath joists? Are the existing joists fitted within the web of the permanent support or is the permanent support fitted at the same height or below non load bearing joists? What opening size (including bearings) is required? What is the total weight of the load that requires support? Which variety of lintel/s or steel/s are specified or most suitable? Whats the length, depth, width, thickness and weight of the permanent support/s? How will the new permanent support be fed into position and how will any old lintels be removed? Which equipment or variety of temporary support equipment is designed to support the masonry correctly and also provides sufficient fitting work access without dangerously over extending and overloading the structure above?
The more temporary support methods known, the safer and easier the different tasks of supporting masonry become. Temporary support equipment options in alphabetical order; Acrow props, Brick Brace, Needles, Prop-Wise and tongued prop attachments. Using the Brick Brace in-conjunction with the traditional propping methods reduces labour & repair time without cutting corners or compromising safety, supports the masonry in between props and also improves the unknown variable safe working load of existing propping methods. Brick Brace with Acrow props, Brick Brace with Needles, Brick Brace with Prop-Wise or Brick Brace with tongued prop attachments and depends on the task at hand of which variety is most suitable.
The Brick Brace counter acts all the hidden problems of propping masonry. A tongued prop attachment dangerously misuses an Acrow prop due to the severe eccentricity of the load and because the web of a tongued prop attachment changes the direction of the load onto the side of the Acrow props inner tube of which is only designed for vertical loads (from the head plate down to the foot plate).
An eccentrically loaded Acrow prop curves and loses height when overloaded or over tightened which is the legal duty of the user not to overload and to work with an Acrow prop fitted with an attachment in a safe, professional & competent manner even though no warning of this is in place. The fully tested Brick Brace safety tool increases the unknown variable strength of lime & cement mortar masonry by creating a force of 40Nm which through testing is proven to be strong and stable enough to prevent collapse during alterations. Brick Brace safety tools are fitted three bricks apart in a cement mortar mix, a maximum of two and a half bricks apart in a weak/ lime mortar mix and within every perpendicular joint upon Block work.Drill out the required perpendicular joint/s with a 10mm masonry drill bit. Insert the Brick Brace safety tool/s and engage fully to the angled plate. Tighten the centre screw with a 19mm socket spanner; the masonry is now reinforced and ready for safer alterations and superior results, guaranteed. Brick Brace Sets Available at.
Superior access upon openings up to 2,250mm within cement mortar masonry & up to 1,800mm within lime mortar masonry. All Opening sizes up to 3,150 mm (14 brick lengths), supporting all 91 bricks within the triangle of masonry above the opening at any height, high or low, with full access to the task.The Brick Brace safety system allows openings up to 4,500mm (20 brick lengths) when using only one Acrow prop fitted central, see photo no9. Use as a safety belt above wider openings when propping to reduce the weight of the load and to prevent collapse. The Brick Brace safety system shares the load equally across the opening to reduce the risk of minor collapse in-between props a. Nd minimising the risk of an Acrow prop curving during a task. The Brick Brace also allows a prop to be maneuvered safely during a task. WHY USE THE BRICK BRACE? The theory behind a tongued prop attachment is to use fewer Acrow props and to reduce masonry damage and is marketed within that manner, which certainly is not the case when the maximum safe working load is only a fraction (1/5) of the correct propping and needling method (if used correctly) and when maintaining the 340kg safe working load the hole within both sides of the cavity wall or a 9 wall is actually larger than fitting a needle and with at least five times more fitting holes required than one 1,700kg safe working load needle. The misleading instructions have increased the risk of the user to underestimate the weight of the load and induces the risk of the user to overload the equipment through further eccentricities and has also suppressed the true level of knowledge that is required to safely tackle the many different tasks of masonry alterations.
9 brickwork can weigh over 600kg per square metre, (120 bricks plus mortar) which would require at least five Acrows and attachments per linear metre (at 167mm centres) on a larger opening on a typical two storey residential property, which could weigh 1,440kg per linear metre without roof loads and making the use of such products unsuitable & obsolete for that task. The traditional tongued prop attachment was designed in the mid 1980s when a typical cavity was only 50mm but due to changes in construction design a cavity has now trebled to 150mm with open plan living accommodation has increased opening sizes.
Attempting tasks which require wider steels with welded top or bottom plates for large cavities and still only using tongues is where more problems of overloading through over extending further from the wall arise. The new instructions updated Nov 2015 strangely suggest that propping an older style 9 wall by over 300mm eccentricity from the centre line of the wall to the centre line of the Acrow prop is acceptable even when the safe working load is reduced to an unknown quantity and when to avoid collapse the tongued attachment is totally dependent on the unknown lateral strength of the lime mortar masonry. The majority of tasks require far more fitting work space than tongued prop attachments can safely offer when still maintaining the maximum 340kg safe working load and when not dangerously removing the opening down to the full finished level without the permanent support being fitted as this increases the risk of collapse through accidental removal of loaded Acrow props during the demolition of the masonry. To reduce the risk of minor and major collapse only a few courses of masonry should be carefully removed to allow for the safe fitting of the permanent support.
Once the permanent support is in the final position and cured, the rest of the opening can then be removed down to the full finished depth. The Brick Brace, guidance, correct procedures, weight charts and proven strategies address all the main causes of collapse during masonry alterations and ensures future generations are taught safely & correctly.
