AJ Wood Civils first started using ‘Boltcracker’ in June of 2015 on our flagship project at the time ‘Baron’s Quay’ in Northwich comprising of a large-scale steel frame on high specification foundations.
Upon trial we found the invention to be a great time saving product for we were not required to install a product such as ‘Denso-tape’ around the bolts as would usually be required when installing bolt boxes, the traditional way.
Once the foundations were cast, to our joy we found that not only were these products saving us time pre-pour, but they also did a much better job of allowing the bolts to be ‘cracked’ the next day, ensuring adequate movement of the bolt for ease of steel frame installation.
Everyone who has constructed these works will have come across the issues with using the traditional method, the next day some bolts may have little to no movement when being cracked, resulting in over strenuous manual handling whilst trying to pry the bolts using various tools. This product thoroughly removed this risk as we were more than satisfied with the end results. So much so that we have used this product ever since.
To summarise AJ Wood Civils have used bolt crackers on over 42 projects and to this day have not had any issues. The product is inexpensive, takes a matter of seconds to install, saves time and money on both labour and materials, and permits a timeframe, unparalleled by any other product, in that these will allow the bolts to be cracked at any point after the pour before the steel frame is ready to be installed, rather than the traditional method which by its very nature stipulates approx. 24-hour timeframe to complete.

I first come across Boltcracker in 2017 when I visited our building supplier and seen it on show. When I seen it I decided to have a look into it and then trialed it on my job. The reason I wanted to trial it was to cut time and the mess of dealing with Denso tape and also having to crack the bolts the next day as sometimes we pour on a Friday meaning the need to have a lad in on a Saturday to ensure the bolts had been cracked. I found that using this product did cut time and mess but also worked a lot more efficiently than the Denso method as all my bolts would crack with ease even days after poured. After the trial I have used the product on all my jobs since and will continue to do so.
