Trained crews. Controlled entries. Repairs where others won’t go.
Specialty Grouting Services are confined space entry experts, providing confined space grouting and repairs across Ontario — inside manholes, chambers, vaults, wet wells, tanks, and pipes. Where standard equipment can’t fit and untrained crews can’t legally go, we bring specialized, low-profile injection systems and people trained to use them safely.
What work do you perform inside confined spaces?
Inspections and condition assessments, troubleshooting sewer flow problems, injection grouting of active leaks, concrete benching repairs, pipe repairs, and ladder and landing installations. One trained crew handles the entry, the diagnosis, and the repair — see the Wellington North manhole repairs for a real example.
How do you make confined space entry safe?
By treating every entry as a planned procedure, not a climb down a ladder. Entries are performed by trained personnel with the monitoring, retrieval, and communication equipment the space requires, working to established confined space procedures.
Why hire a grouting contractor for confined space repairs?
Because splitting the job doubles the entries. A safety company can get into the space but can’t fix it; a repair contractor may not be equipped to enter it. Our crews do both — which means fewer entries, less downtime, and one point of responsibility.
Frequently Asked Questions
Generally, a space not designed for continuous occupancy with restricted entry or exit — manholes, chambers, vaults, wet wells, tanks, and pipes all qualify. If you’re unsure whether your structure requires entry procedures, ask us before anyone goes in.
Entry complexity, flow conditions in live structures, the repair scope itself, and travel. Combining inspection and repair in one mobilization is usually the most economical route.
Yes. We routinely work in active manholes and chambers, including troubleshooting and managing sewer flow while the repair proceeds.
Yes. Ladder and landing repairs and installations in manholes and chambers are a regular part of our confined space work — completed for municipalities such as the Township of Wellington North.
Yes, and it is the most efficient way to buy this work — one mobilization, a structure-by-structure report, and a repair record for each asset.
