Does Pressure Washing Damage Block Paving?
Most people look at water as the most innocuous substance on earth, but if you give it enough time and if it is in the right kind of conditions there is a pretty good chance that it may very well be the most destructive force currently known to human kind. Water can erode entire coastlines, and even something as innocent as leaving it in some concrete can result in it freezing when it gets cold which would make it expand as well thereby increased the size of the hole that it has already started to create.
The truth of the situation is that power washing services near me might hesitate to wash block paving for you because of how damaging water can be to it, especially if it is being ejected at a pressure level that is on the higher end of the spectrum. This is because of the fact that water can erode a sizable amount of the surface of your block paving since it has the pressure it needs to start doing damage, but you can take steps to mitigate the likelihood of such circumstances and results.
The most useful thing to do here is to spray your water at an angle. That will allow you to spread the water over a larger area which can then decrease its overall pressure. The pressure will still be high enough to clean the block paving of course, but it will stop well short of being so high that erosion will start to occur. The fact of the matter is that learning about adequate pressure washing techniques can show you how safe it can be as long as proper precautions are followed.
