About the product

UltraCrete PY5: FLOWABLE POLYESTER RESIN SYSTEM

Ultracrete PY5 is a flowable, polyester resin perfect for anchoring bolts or bars, bedding lights in carriageways, for backfilling manhole covers and sealing surface cracks. PY5 conforms to HA104/09, is incredibly robust & withstands huge wear. Ultracrete PY5 boasts a 85N/mm² compressive strength gain in just one hour, this rapid set time means that the repaired areas can be open to traffic in as little as just 40 minutes.

  • Rapid strength gain
  • Excellent flexural & tensile strengths
  • Complies to Department of Transport Design Manual for Roads & Bridges;
  • Manufactured under a Quality Assurance Scheme BS EN ISO 9002: 1994

Typical Applications

  • Rapid installation of manhole frame gulley grates kerbs
  • Repair to spalled & damaged areas in concrete floors, paths & roads
  • Anchoring dowel bars
  • Installation of ductile ironworks
  • Jointing & repair pre-cast concrete units

How to prepare PY5 for anchoring dowels and bars

  • Holes should be either drilled using percussion drill or scabbled to provide roughened faces.
  • Pre-formed holes should be scabbled to provide a key.
  • Holes must be free from water, dust and any debris that might affect bond.
  • Dowels or bars should be either deformed or threaded; smooth bars are not recommended.

How to prepare PY5 as a flowable mortar

  • PY5 is the ideal accompaniment of PY4 when bedding ironwork.
  • Its flowable texture when mixed can be poured around the frame ensuring all voids are filled.
  • With its high early compressive, flexural and tensile strengths, this material creates a long lasting repair in the most arduous situations.

How to mix PY5 Polyester Resin Bedding Mortar

PY5 should be mixed by forced action mixer or by vigorous hand mixing with an appropriate tool:
  1. Add one tin of resin to the pack of filler/activator (or 2 tins of resin to the 2 filler/ activators).
  2. Pour resin from the tin into the outer bucket and slowly add the filler until a homogeneous mix is attained.
  3. Do not part-mix material. Use immediately after mixing.

How to apply PY5 Polyester Resin Bedding Mortar

  • Apply the PY5 material immediately after mixing.
  • Do not try to re-mix once initial hardening is evident.
  • Do not lay in standing water.
UltraCrete PY4 and PY5 are high-performance, fast-setting polyester resin systems developed by Instarmac Group plc for highway maintenance and ironwork reinstatement. PY4 is a rigid bedding mortar designed to support manhole frames and covers, while PY5 is a flowable resin used for anchoring, backfilling, and sealing applications. Both are engineered to deliver durable, long-lasting repairs in high-traffic environments where speed and strength are critical.
