In this video I am with my mate Gil as we test the ground bearing capacity for a new garden room that I am working on, we do this to establish how many screws we need, what length screws we need and then the total number required to support our new structure.
By testing how much force it takes to remove the screw hydraulically we can do a mathematical calculation to establish the potential load, once we have established this we use a safety factor of 50% so if we feel that the loading is 2500kg we would safely assume that a load of 1250kg will be no problem.
Then we will work out the weight of the new structure allowing for live loads such as the effects of wind and the movement of people and placing of furniture etc, this will establish the minimum number of ground screws that we will need. Regardless of the minimum number we add screws where there may be a point load or additional loading so invariably we have a few more that we need.
Ground screws are a swift and economical way of forming a suitable foundation that is eco friendly and compared to a 1m deep mass filled concrete footing and brickwork and blockwork to dpc
