STRONGSET™ – One Concrete Mix for Countless Jobs Around the Property
Common Uses:
- New concrete construction including footings, sidewalks, slabs, steps and patios
- Setting deck posts, fence posts, sign bases and poles
- Concrete repairs or overlays above 50 mm (2 in)
Features:
- Ready to mix and place – just add water; ideal for DIY and contractor use
- Open to foot traffic in approximately 24 hours (job conditions vary)
- Versatile, general-purpose performance – great for slabs, steps, patios, walkways, and more
- Designed for placements 50 mm (2 in) and thicker
- Meets strength requirements of ASTM C387 – 27.5 MPa (4000 psi) at 28 days
Preparation, Mixing & Application:
- Prepare your site with properly braced formwork and a well-compacted, dampened sub-grade — no standing water.
- For post setting, excavate the hole below the frost depth with a diameter 100 mm (4 in) wider than the post.
- Mix each 30 kg bag with 2.7 L (2.85 qt) of potable water manually in a wheelbarrow or mortar box, or mechanically in a drum mixer, until uniform with no dry pockets.
- Place and consolidate the concrete to full depth, screed level, and finish only after bleed water has evaporated.
- Maintain ambient and material temperatures between +5 °C and +30 °C (40 °F and 86 °F) for at least 24 hours before and 48 hours after application. For temperatures below +5 °C, use PIVIT FAST STRONGSET™.

FENCESET™ – Fast, Simple Post Setting – Built for Installation Day
Common Uses:
- Fence posts
- Lamp posts
- Playset posts
- Sports equipment posts
- Mailbox poles
- NOTE: DO NOT use for structural applications such as deck posts, floors, slabs, sidewalks or footings.
Features:
- Mix and place in the hole without mixing equipment – no wheelbarrow needed
- Posts ready for use in approximately 3 hours
- Sets in 5-8 minutes – reduces bracing time and keeps installation moving
- Once the post is positioned, you can place the dry material, add water, and agitate to blend — then level and align right away. FENCESET™ is ideal for property projects and light-duty post installations where you want a clean, efficient workflow and reliable results.
Preparation, Mixing & Application:
- Excavate the post hole below the frost depth with a diameter 100 mm (4 in) wider than the post.
- Saturate the soil in the hole with water – damp but no standing water.
- Position the post in the centre of the hole. Add FENCESET™ and 2.8 L (3.0 qt) of potable water per bag around the post at the same time, then blend using a rod or hand tool.
- Ensure the post is level – bracing is not typically required as FENCESET™ sets in minutes.
- Do not rework concrete or move posts after the material has begun to set. Maintain temperatures between +5 °C and +30 °C (40 °F and 86 °F). For temperatures below +5 °C, use PIVIT FAST STRONGSET™.
