No mix-design change
Keep your concrete recipe and structural design. SubLay C works in the soil contact zone around the asset.

SubLay C
Form 1 ready to pilotProtect buried concrete without changing the mix.
SubLay C turns ordinary backfill into a mineral corrosion shield around buried reinforced concrete, without changing the mix design.
Mineral protective bedding for buried reinforced concrete
Why SubLay C
Durability that fits how you already build.
SubLay C Form 1 is engineered protective backfill for the buried sides and base of reinforced concrete. Forms 2 and 3 use the same material system in precast and cast formats.
Other products protect the steel, the concrete mix, or the concrete surface. SubLay C treats the soil that attacks them.
Fits a normal foundation day
Place, compact, and backfill with clear thickness and QC guidance your contractors can follow.
Built for aggressive ground
Designed for the chloride, sulfate, and moisture exposure that eats ordinary backfill, including acidic sulfate-bearing coastal ground and salt-loaded roadside soils.
Protective by design for wide networks
A mineral bed meant for many buried assets, so durability work does not trade off against a clean contact environment around the structure.
Pilot with a monitoring plan
Start with a pilot pack: material, application guidance, and a practical monitoring plan.
How it works
Place a mineral shield. Keep your mix design.
Place SubLay C Form 1 around the sides and base of poles, foundations, and other buried elements. Ordinary soil stays outside that protective bed.
Cross-section: SubLay C sits around the buried part of the concrete structure so it does not sit directly in regular soil.
- 01
Prepare the contact zone
Clear and prepare the contact zone around the buried part of the concrete structure.
- 02
Place SubLay C Form 1
Place SubLay C around the sides and base of the submerged structure at the agreed thickness.
- 03
Compact
Compact to the civil specification agreed with your team.
- 04
Backfill remaining zones
Fill the rest of the trench with regular soil around the SubLay C bed.
- 05
Monitor on pilots
On pilots, install monitoring points and record lot ID, thickness, and date.
Delivery forms
