Promoting Better Practice During Masonry Alterations

The stability & lateral strength of masonry during alterations is unpredictable & varies upon every task, of which depends upon the length of the opening, the mortar mix, the age & the quality of the masonry.


The fully tested Brick Brace safety tool increases the unknown & variable strength of bonded lime & cement mortar masonry to 40Nm which through testing is proven to be strong and stable enough to prevent collapse.

The Brick Brace is designed to offer further & safer options, to give superior results with a safer fitting/working access and prevents the overloading of existing propping methods.

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.

The Missing Link To Safer & Superior Alterations!

We have studied temporary masonry support for many years, more than anyone before us. Our fully patented method of strengthening masonry before any alterations take place is the further preparation required for safer and superior results, GUARANTEED!

The main cause of collapse is overloading due to underestimating the weight of the load and when removing Strongboy’s further from the wall to either avoid internal 1st floor wall damage upon finished rooms and when attempting to gain more fitting work space as over extending greatly affects the safe working load.

The Maximum Safe Working Loads


A correctly used Acrow prop, 3,400Kg.

An Acrow prop, used within the props and needles method, 1,700Kg.

 Don’t Be Fooled By The Name!

When fitted with a Strongboy or any other similar designed product, 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 of a Strongboy must fully penetrate the internal skin when supporting a cavity wall, as seen in the drawing below.

hse 1

When removed from the wall to avoid internal wall damage or to gain further fitting/work space, the safe working load reduces to an unknown quantity.

We do not endorse the misuse of any temporary support equipment but anyone that continues to overload Strongboy’s through over extending from the wall to gain further fitting space and/or to avoid internal 1st floor wall damage, we highly recommend bracing the masonry beforehand to reduce the risk of collapse from overloading.


Fit a permanent support with ease at any height, replace lintels, replace cavity trays and D.P.C’s with nothing to impede. Re-instate a load point to reduce the weight of the load & safely reduce the number of impeding props from the fitting area. The Brick Brace reinforces & stabilises masonry for a number of different tasks, including under pinning & window replacement and is a further aid for all remedial works, brickwork renovations & repairs,especially alterations within lime mortars, as seen within the photo below.

Full Set £275.00

The Brick Brace safety system allows openings up to 4,500mm (20 brick lengths) when using only one Acrow prop fitted central and scaffold clipped to the horizontal scaffold tube.  

where to use 04

And also use the full set above larger openings when propping or needling to safely reduce the load & the number of Acrow props from the fitting/work area, to hold the brickwork in-between props and to also support the masonry as one whole piece rather than individual bricks as in the case of only propping.


The many different tasks of masonry alterations require far more preparation & knowledge than having the ability of using Acrow props fitted with Strongboy’s, as it’s not possible for a Strongboy to give the correct fitting work space for every task without dangerously overloading itself or through removing an opening down the full finished level before the permanent support is in the final position as this increases the risk of collapse through accidental removal of loaded Acrow props during the demolition of the opening.

To reduce risk, 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, then the rest of the opening can be removed down to the full finished level.

It’s urban myth that the Strongboy is suitable for every task, with the instructions changed by enforcement of the H.S.E in November 2015 and now read;

“Before using a Strongboy you should identify that it is a suitable method to carry out the intended works”.

The Strongboy has increased the risk of the user to underestimate the weight of the load due to 25 years of misleading instructions and has also suppressed the true level of knowledge that is required to tackle the many different tasks of masonry alterations safely & correctly.

We provide guidance to help, teach and influence the majority to change their bad habits, to help prevent the same needless reoccurring accidents and to ensure future generations are taught safely & correctly.

Strangely the theory behind a Strongboy 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 and when maintaining the 340kg safe working load the hole within both sides of a 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.  

Without warning! A Strongboy dangerously misuses an Acrow prop due to the severe eccentricity of the load and because the web of the Strongboy changes the direction of the load onto the side of the Acrow props inner tube of which is designed only for vertical loads from the head plate down to the foot plate.prop wise product wording 2

 An Acrow prop fitted with a Strongboy 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 a Strongboy in a safe, professional & competent manner even though no warning of this is in place.

 Guaranteed to pay for itself within two applications!

To fit the Brick Brace Safety Tool you require a hammer drill with a 10mm masonry drill bit to remove the mortar from the perpendicular joint and a 19mm socket spanner to expand the inserted Brick Brace.

The Brick Brace safety system requires a scaffold tube,Hammer Drill, 8mm and 10mm masonry drill bits, 15, 19, 21mm sockets and a ratchet. The 40Nm torque required to expand the Brick Brace is similar to tightening a scaffold fitting. To remove the masonry below, use a disc cutter and a light set hammer drill with the correct chisel fittings, a masonry or traditional hand saw is sufficient for lime mortar mixes, full instructions and a correct procedure are provided and also available to read or print via our instructions/download page.

Know your legal duties as a builder by reading our 2019 masonry wall propping guide.

The Brick Brace knowledge, guidance, correct procedures, weight charts and proven strategies address all the main causes of collapse during masonry alterations and will keep you within the C.D.M 2015 guidelines of which now also covers small  domestic projects.

For a superior safe working load the Prop-Wise uses the top head plate of the Acrow prop, rather than the Acrow props inner tube.

Designed with a flat head to ease internal use at ceiling heights and fits neatly into a tool bag.

The safest method of propping 4″ to 6″masonry.

Using fewer Acrow props due to the reduced eccentricity which also gives a superior safe working load.

Maximum safe working load 500kg, supplied with full instructions and Acrow prop guidance and is by far the safest tongued prop attachment on the market.

 (Builder From Surrey)

 Top quality product.

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!
