What pier hole cleaning covers
Pier hole cleaning removes loose spoil, slurry and water from pier holes that have already been bored, using a vac truck's suction hose. It is a clean-out task only. Drilling the holes is a separate job for the piling or drilling contractor, and the clean-out is not new boring, utility potholing or general liquid waste removal.
The Sydney team operates 24/7. Talk to them about timing the clean-out around your drilling, inspection and pour.
What stays with your engineer and piling contractor
Whether a hole is clean enough, stable and ready for inspection or concrete is decided by the project's engineer or the person responsible for the footings. The clean-out crew removes material. It does not certify the hole, its depth or the ground around it.
Ground and groundwater conditions vary between sites, and some projects need drilling, cleaning, inspection and pouring to follow closely. Check the sequence and timing your engineer requires before booking, and share any written instructions with the team.
What to send for an estimate
- The number of holes, and the diameter and depth of each if known.
- What is in them: loose spoil, slurry, groundwater or rainwater.
- The site address, where the truck can park and the distance from the truck to the holes.
- Any project instructions on cleaning, inspection or timing.
- When the holes will be ready, and when inspection or concrete is booked.
- A site plan or photos of the holes and the access route.
Call the Sydney team on (02) 5302 6020 24/7 to talk through the job, hourly rates and an estimate, or send hole details, plans and photos through the contact form.
Where the collected material goes
Spoil and water lifted from the holes go into the truck's tank and are taken off site. How they are handled depends on what they are. NSW EPA's Waste Classification Guidelines allow liquid and solid fractions to be separated and assessed, so tell the team about any known contamination, fill or unusual material.

Pier Hole Cleaning FAQs
Does pier hole cleaning include drilling the holes?
No. This service covers cleaning out holes that have already been bored. Drilling is arranged separately with your piling or drilling contractor.
Will the holes be ready for inspection or concrete after cleaning?
That decision belongs to your engineer or the person responsible for the footings. The clean-out removes loose material and water so they can carry out their inspection. If they ask for more cleaning, call the team to discuss it.
How deep or wide a hole can be cleaned?
It depends on the equipment, the hole and site access. Send the number of holes with their depth and diameter if known, and the team will confirm whether the job suits a vac truck.
What if the holes keep filling with water?
Say so when you enquire. Ongoing inflow changes how the job is planned, and water removal may need to be timed with the inspection or pour. The dewatering guide explains what to describe.
