We ensure the ties are going to work by carrying out a pull test on each and every job we do to ensure the ties are going to do their intended job. We select the correct drill bit diameter for the masonry, i.e. dry pressed brick or extruded, and also the drilling action used, percussion or SDS. Percussion has a faster cutting action while SDS is more of a hammer action, This makes all the difference to how well the ties will perform once installed.


If your installer doesn't insist on a pull test on the ties, show them the door!!

We can locate the existing wall ties by use of metal detectors, visual inspection via wireless camera and examination of the cavity by removal of a brick(s).  Before, During or After the ties are installed we are able to test them for a proof loading as can be seen in the photos above.















​We have seen many times where the wrong drill, drill bit, or even the wall tie installation method selected has been incorrect and you can literally move the end of the exposed tie with your finger!


 Having been to jobs to instruct other remedial building companies' tradesmen, on the correct procedure and installation of replacement cavity wall ties, you can rest assured we know what we are doing.


Helicrete is dedicated to doing the job correctly with integrity and doesn't like to cut corners. We typically exceed the required pull-out force for replacement cavity wall ties by selecting the correct diameter drill bit and using the correct drilling action when creating the tie's pilot hole. Through experience we know when the tie is securely fixed during installation, if it isn't we will install another tie in close proximity. We would rather carry out the work correctly than just install the cavity wall ties and take the money.​​
