Firstly, let’s start by busting a common myth which we hear all the time. Will pressure washing damage my driveway? Concrete is not invincible.

Yes, it’s tough wearing and can withstand almost all weather conditions. Still, as far as its potential to be damaged, concrete is just as vulnerable as anything else when treated incorrectly.

You may be wondering how a tool designed for cleaning can damage your driveway. After all, pressure washers only use water, and water is harmless, right? Wrong. Operate under extremely high-pressure jet streams; pressure washers can cause irreversible damage to everything from paintwork to concrete surfaces, which can lead to costly repairs and sometimes hazardous results.

What kind of damage can a pressure washer cause?

• Depending on the kind of concrete you have on your driveway, a pressure washer can do anything from creating lines to leaving pitted holes or completely deteriorating the joints between slabs.
• If pointed too directly or too close to a vulnerable area, the washer can create cracks in the jointing sand between paving slabs – leaving the surfaces uneven and loose.
• It merely speeds up the ageing process of the concrete, leading to accentuated weathering which, if untouched, could otherwise take years to surface.

Though not all these potential risks are applicable for all types of driveway, whether you have paving slabs or solid concrete does not exclude you from the threat of irreversible damage.

How can a pressure washer damage a driveway?

The damage caused comes not from the equipment itself, but the misuse of it – and this is often down to a lack of experience and understanding.
Setting the pressure too high and pointing the jet at a surface directly. And even holding the stream on a specific area for too long, how a pressure washer can cause damage often occur quickly and without warning.

How can I avoid damaging my driveway during pressure washing?

As with any new piece of equipment, they are reading the instructions before using the washer will allow a new user to familiarise themselves with the operation of the tool.

I would suggest that you try the jet on an area which is unlikely to be subject to damage; aiming for some solid brick or an area of concrete which is unlikely to cause any hazards.

We are helping you to practice pointing the jet with the optimum precision and angling.

And, of course, if in doubt, professional pressure washing cleaners are trained to use the equipment not just effectively but also safely – ensuring a great clean and finish, while also protecting your driveway from the hazards that misuse can cause.
