Rock breaking with hydraulic hammers where excavation meets bedrock — foundation and basement digs, drainage and ducting trenches, reduced-level formations and road formations. Broken rock is crushed for re-use as fill where suitable or carted away, and formations are cleaned off ready for engineer inspection.
Rock breaking uses a hydraulic hammer mounted on an excavator to break bedrock or large boulders that a bucket cannot excavate, typically in foundation digs, drainage trenches and reduced-level excavation. The broken rock is then dug out and either crushed for re-use as fill or removed. Rayco Civils carries out rock breaking across Ireland.
A site investigation or trial holes give the clearest answer before work starts. Otherwise rock often only shows once the dig is underway, which is why it is usually priced separately from ordinary excavation.
Breaking rock is far slower than digging soil and needs a hammer rather than a bucket, so the rate and the programme are different. Pricing it separately keeps the quote honest instead of loading every dig with a rock allowance.
Yes. Broken rock can often be crushed and re-used as fill or sub-base on the same site, which reduces both cart-away and imported stone.
Hydraulic breaking is noisy and produces vibration, so on built-up sites it is best kept to agreed working hours and neighbours told in advance.
