Can Heavy Rains Harm Your Driveway?

They say that when it rains, it pours. Does it ever come to your mind if heavy rains will damage your driveway?

If you notice on parking lots during rainy days, you see a lot of puddles of water, attesting to the truth of slippery when wet. Does your driveway is like this when it rains?

There are stories and experiences untold that driveways, walkways, and patios do not drain properly when the strong rain comes. In other words, the surface used on them is not as efficient to drain streams of water.

It is not the rain that is to blame here but the ability of the driveway pavement to release water runoff.

Collected water from rain if not dried up quickly will stay there and cause damage to the surface.

What kind of driveway or patio surface is most efficient in draining heavy droplets of rain?

Why Rain Destroys Your Tarmacadam Driveway

The type of driveway surface that is vulnerable to rain damage is tarmacadam. How?

Tarmac and asphalt are often interchanged but the difference lies that the latter uses bitumen, a modern variation sourced from petroleum distillation.

Tarmacadam surface is a highly porous material, with particles not as intact compared to concrete and block paving. Resin-bound on the other hand has the most sealed surface due to resin application that makes the pebbles compact.

Tarmac, for short, is a layer of crushed aggregates coated with tar. The tar is poured over the aggregates and flattened with a heavy roller to make the top surface smooth.

With the continuous outpouring, the water will eventually seep into the driveway’s foundation and begins to destroy its structural integrity.

Another reason why rain is potential damage to the tarmac is the poor drainage system. Once there is excessive pooling of rainwater because it has no way to drain out, it will serve as a puddle. The puddle will soften the spots due to changes in temperature and freezing of water that seeped in causing the cracks inside.

Problematic ground slope

Poorly installed driveway is exposed to damage when not fixed. An uneven slope in the construction of the driveway will let all of the rainwater stand in one place.

If your driveway is sloped directing water to a path that is not for proper draining, the water runoff will damage those affected by overflow. If there is stagnant water, it serves as a harbouring spot for mosquitoes.

What to do to protect your driveway

Replacing an old new driveway may be out of your budget. What you can do instead is take preventive measures so that you can still benefit from your driveway several years more.

Here are some tips to have a durable driveway:

  1. Fill small cracks before they get bigger and are difficult to repair. With cracks that turn into a hole, it is more damaging to your car, people, and the surface.
  2. Avoid chemical spills on your driveway surface. Most of the time, oil spills and other chemicals are the reason for premature aging.
  3. Conduct periodic maintenance. If possible or if budget permits, consider a resurfacing project to maintain your driveway’s integrity, especially when there a number of damages. Leaving those damage out for a longer period will only cause more damage in the end and will end you up paying more for repairs.
  4. Avoid parking on the same spot. This is to prevent your car from creating dips that will serve as spots for pooling.
  5. Ask for professional help for driveway maintenance if you have no plans of replacing the old surface yet. Their constructive assessment will provide you steps to protect your driveway and make it more useful for many years.
