Inspect before signing.
Document damage or shortages on the Bill of Lading and notify P3 immediately. Stage pieces level on wood blocks—never directly on the ground.
P3 POLYMERSCONTRACTORS / FIELD WORKFLOW
Price it clearly.
Set it confidently.
Polymer concrete changes the material—not the familiar precast sequence. Start with the plans you have, then move from delivery through installation with the relevant P3 and component-manufacturer guidance close at hand.

01 / BEFORE THE BID
Start with what you have.
These are the main factors we use to quote every structure. If you have this information ready to go, it helps us turn pricing around quickly. If you don’t have it all, just send whatever plans and specifications you have. P3 can perform the structure takeoff, review the product requirements, and come back with any questions needed to complete your quote.
Send plans + request pricing- 01Structure diameter, total depth and component arrangement
- 02Pipe material, actual outside diameter and connection type
- 03Pipe invert elevations, opening locations and orientation
- 04Top configuration, access opening, frame and cover requirements
- 05Project loading and groundwater criteria supplied for product design
- 06Delivery sequence, component weights and requested delivery date
02 / DELIVERY + LIFTING
Plan the pick before the truck arrives.
Confirm component weights and use the embedded side lift pins with a spreader bar, standard chains and hooks. Keep chains within 30° of vertical and clear of the component.
Match the rigging to the marked lift points.
Verify the component weight and rated rigging. Lift only from the embedded side pins; do not use pipe openings or joint faces.
Protect the piece.
Keep chains off the structure, avoid impact and confirm that joining surfaces, connectors and lifting points are clean and undamaged.
03 / INSTALLATION
Four hold points prevent most avoidable problems.
01FOUNDATION Start level and fully supported.
Set on a firm, stable foundation. Replace unstable material with compacted crushed stone and provide the bedding required for the design loads.
DO NOT CONTINUE IFThe subgrade is soft, pumping, unstable or different from the approved condition.02JOINTS Clean, seal and fully seat.
Remove dirt, grease and contaminants. Install the project-specified butyl, gasket or polymer grout in the bell or keyway exactly as its manufacturer directs.
DO NOT CONTINUE IFA joint face is chipped, contaminated, misaligned or will not seat evenly.03PIPE CONNECTIONS Match the actual pipe O.D.
Install the selected flexible rubber connector in accordance with ASTM C923 and its manufacturer instructions. Corrugated pipe requires the specified adapter.
DO NOT CONTINUE IFThe actual O.D., opening, connector model or approved shop drawing do not agree.04BACKFILL Build evenly around the structure.
Use project-specified material, hand-place and tamp in 12–24 inch lifts, and keep heavy equipment off the manhole during backfill.
DO NOT CONTINUE IFBackfill is moving the stack, opening joints or loading a pipe connection.
04 / FIELD DOCUMENTS
Open the sheet for the product in front of you.
These are reference documents, not a substitute for the approved project submittal. Confirm the model, size, material, and revision supplied for your structure before installation.

OPEN PDF05 / FIELD MODIFICATIONS
Familiar tools. Better guidance before the cut.
Polymer concrete can be cut, cored, drilled, and ground with the same equipment and diamond masonry tools used for standard concrete. We recommend contacting P3 before any field modification so we can review the location and share practical guidance for a clean result.
- Confirm the proposed opening size and location
- Identify the structure and affected component
- Check the approved drawing and nearby interfaces
- Select appropriate cutting, coring, or drilling equipment
- Get guidance for finishing and sealing the modification
