Hello,
We have a sloped shared driveway and one side has just cracked from a truck going up and down the driveway. On closer examination, it is clear that the soil underneath has eroded and the concrete did not have any support anymore. What could we do to repair the damage and give it more support to ensure it doesn't get worse?
Thanks.
Hi @Shane,
Given the erosion beneath the concrete, the best course of action would be to cut out the broken and unsupported section entirely, fill beneath it and re-pour a new slab in that area. That way, you can ensure the base is properly compacted and supported before the new concrete is laid, which is essential for long-term durability, especially on a sloped driveway that sees vehicle traffic.
As for the rest of the driveway, it would be wise to have it professionally assessed. A contractor can check for any other voids or soft spots under the surface and determine whether any soil stabilisation or filling is needed to prevent further sections from failing the same way. If voids are present elsewhere, they can often be filled with flowable fill or a polyurethane injection to restore support beneath the slab without needing to remove it.
Please let me know if you have any questions.
Mitchell
