Is it OK to put mulch over road base?

[Ganny000]

Hi, 

I’m thinking of getting road base and compacting it to my front yard of 7x3m

After that I’m planning to put mulch over it. Reason I put road base is so that I could park my car on it 

I’ve checked on a lot of website for ideas but never seen people laying mulch over road base

Thanks

Hey @Ganny000, 

I've seen people use a Crusher dust (which is  crushed from the same kind of rock as road base but much smoother) / Mulch combo, but that was to prevent plant growth, not park a car on it. I imagine road base would create a pretty uneaven surface?

Welcome to the Bunnings Workshop community @Ganny000. It's wonderful to have you join us, and many thanks for your question about creating a car park.

I think your idea will work as long as you level and compact the area. I recommend hiring a plate compactor to ensure the roadbase is solid. As @Remarka6le has mentioned, typically, you'd use crusher dust in combination with roadbase. The crusher dust works its way in between the larger rocks and helps to form a solid base. After you've compacted the area, I can't see any reason why you couldn't cover it with mulch.

You could also compact the soil and lay down Strol 0.5m² SurePave Plastic Pavers. You'd then be able to cover the plastic pavers with mulch.

Please let us know if you have any questions.
