Advanced pile encapsulation grout


A-P-E GROUT is an aggregate filled epoxy system that is especially designed for placement by the plural component method, both above and below the waterline. A-P-E GROUT is used with the Advanced Pile Encapsulation (A-P-E) process and other applications where grout must be placed in relatively large volumes.


  • Encapsulation of piles, columns, beams and risers when combined with translucent fiberglass reinforced plastic jackets.
  • Use with pipeline and structural repair clamps.
  • Repairs to structures of all types, particularly where difficult or underwater placement is required.
  • Mass in-fills, both above and below the waterline where controlled reaction times and relatively low exothermic heats are required.


  • High flow, self-leveling formulation.
  • Bonds under water (seawater or fresh) to wood, concrete or steel.
  • Provides good underwater bond strengths to properly prepared surfaces.
  • Plural component batching, mixing and pumping greatly reduces handling and clean-up problems.

The performance and effectiveness of A-P-E GROUT are dependent on the design and installation factors of each project.


Component A: White
Component B: Black
Components A and B, mixed: Gray


A-P-E GROUT is packaged as follows:
Component A:Ê10 and 100 gal (37.8 and 378.5 L) units
Component B:Ê10 and 100 gal (37.8 and 378.5 L) units
Component C:Ê50 lb (22.7 kg) bags
One 10 gal (37.8 L) unit of Component A and one 10 gal (37.8 L) unit of Component B, when mixed with six 50 lb (22.7 kg) bags of Component C, will yield approximately 3.18 ft3 (0.09 m3).


Mix Ratio
A:B (Binder) 1:1 by volume
C:A&B (Binder) 3.38:1 pumpable by mass

Bond strengths are highly dependent on the application and installation conditions. Consult your local Master Builders representative for additional information.


Methods of surface preparation, application and handling will vary due to the broad scope of specialized applications. For information on estimating, application, pump equipment and further recommendations, contact your local Master Builders representative.


Shelf life is 12 months minimum when stored between 50 and 120 mF (10 and 49 mC) in unopened containers.


  • Application temperature is 55 and 115mF (13 and 46 mC).
  • Minimum cure temperature is 55 F (13 mC).
  • To obtain maximum bond strength, local water conditions have to be taken into account and appropriate surface preparation procedures have to be followed.


Clean the mixed epoxy before it hardens. Solvents such as acetone, methyl ethyl ketone (MEK) or toluene may be used. Commercial epoxy strippers such as CONCRESIVE 6003 are recommended for hardened epoxy. Consult solvent manufacturer's usage recommendations.


A-P-E GROUT resin and curing compounds may cause allergic skin reaction. Materials are harmful if swallowed. Vapors may cause headaches, dizziness and nausea. Prolonged or repeated contact may cause eye irritation or other allergic responses such s skin irritation or dermatitis. Avoid contact with skin or eyes. In case of contact, wash skin with soap and water. Flush eyes immediately with water and consult a physician immediately. If used in confined areas, provide adequate ventilation. Use eye protection, protective clothing, rubber gloves and barrier creams. For detailed safety information, please refer to the product Material Safety Data Sheet (MSDS).
Part C: Silica sand contains free silica. Avoid breathing dust. Prolonged exposure may cause delayed lung injury (Silicosis).
Product Material Safety Data Sheets are available and should be consulted when handling products. These products are for industrial and professional use only; application directions must be followed.
