Thanks for all the replies, appreciate the input. Only now managed to catch up on the various suggestions. We will discuss this, and the wonderful advantage of Corefix a little further on. First, take a look at the video above where you will see just how powerful the Corefix dot and dab plasterboard fixings are. Why is Fixing to Dot and Dab Plasterboard a Problem?

Once the plug is in the wall, a steel tube is pushed into the end of the plug. This tube is hollow and very very strong. It is long enough to go right through to the masonry wall where it, after being hammered home, forms a really tight fit about 25mm into the masonry wall. It’s no secret, we love them! This hideous problem that has plagued us (and many many others) for many many years has now magically gone away thanks to Corefix. The steel tube, as you can see from both the video and the image below, bridges the gap in the dot and dap wall. 50% of the steel tube is held in the masonry which is how the load is supported at the other end of the screw. In 2017 statistics show that almost 80% of people are installing TV’s which range between 40 and 55 inches (Source Statisista.com). This is the number one problem with using ordinary plugs and screws to a dot and dab plasterboard wall. How Does Corefix Work?In terms of expense, I'm not too fussed. The cost of fixing the wall, water leak on the floor and broken copper pipes far outweighs the initial cost. Thought splashing out on the Corefix screws was the answer but it wasn't meant to be as straightforward as that. Remove any dust or debris from the hole before gently tapping the Corefix plug into place until the flange sits against the plasterboard. This clearly depends on the size of the television but with all the major brands such as Sony, Samsung & Panasonic all making flat screen TVs up to a staggering 100 inches and above in some cases, it really is important to know the weight of your TV and know your hollow wall plasterboard fixing will support the load. Below are some approx. weights for standard size wall mounted flat screen TVs* Corefix can be installed in less than one minute, without the need for specialist tools – all you need is a 10mm masonry drill, hammer, and a screwdriver:

The diagram shows what Corefix can hold and 250kg is almost 39.5 stone or 3/4 averagely built people – That is very impressive indeed. How and Where do I buy Corefix?Coach screws maybe. Ideally I'd use the 5 different 10mm holes I've already made into the wall. So they'd have to be 10mm x 100mm min in dimensions. Using a 4-inch wall plug, with the main body of the plug at a 10mm diameter, the Corefix wall plug is pushed into a 10mm hole. It is not pushed through the plasterboard however as the lip at the head of the plug will prevent that happening. A screw, in this gap, is not supported and any heavy load applied to the end of it will cause the screw to bend. This can result in cold spots on the wall which, in turn can result in condensation and condensation around the window reveals of a dot and dab plaster boarded room is very common.
