If you own an older septic system, you know the frustration of having to dig every time service is required. At Planes Precast Concrete Ltd., we’re proud to be the only supplier in the Kingston area carrying Polylok’s risers, lids, adapter rings, and safety screens—products designed for easy retrofits that are approved under the Ontario Building Code. These upgrades make septic maintenance safer, faster, and more cost-effective for both homeowners and contractors.
Why Retrofit with Polylok?
Risers & Adapter Rings – Access Without the Digging
Polylok risers bring your septic tank access right to ground level, eliminating repeated excavation. Adapter rings provide a secure, watertight connection between the riser and your existing tank lid.
Secure, Long-Lasting Lids
Polylok lids include gaskets that form a watertight seal, preventing surface water infiltration and controlling odors. They’re strong, lockable, and provide safety for families by preventing accidental entry.
Safety Screens – Protecting Your Drain Field
Polylok safety screens prevent solids from leaving the tank and clogging your drain field. This simple addition helps extend the life of your system and prevents costly failures.
