Monneli Epogrout PC Extra

Flowable Epoxy Grout for Pile Treatment

EPOGROUT PC Extra is designed as a pile head treatment. The applied product seals the pile head with a continuous, fully bonded and totally waterproofing barrier. The system prevents the underground water to seepage by capillary force along the reinforcement bars into the pile cap. Such protection will prevent any possible water leakage to the building and will protect the pile caps reinforcement from corrosion. It can also be used in anchors, rails, cranes and bridge bearing seats.

Application Information
Instructions for use

Surface Preparation

The pile head surface must be clean, sound and uncontaminated. Remove all dirt, laitance, grease or any other foreign material. Remove all loose particles or defected concrete. Use EPOFINISH or BETOCEM HR to repair / re-profile the pile head.

The pile head surface should be cleaned and completely dry just before applying the product.
Pile reinforcement bars should be straightened, clean and free from rust. Steel bars may be protected by the application of one coat of BETOFER or EPOZINC (steel primers).

EPOGROUT PC EXTRA is a fluid product. Fix a complete leak proof wooden formwork around the pile head. Use sealant, foam or rubber strip to seal the joints in the formwork and to close the gaps between the formwork and the pile head. Coat the formwork from inside with a high quality release agent to ease the de-bonding of the shuttering afterwards.


EPOGROUT PC EXTRA is supplied as a three-component kit consisting of base, hardener and a bag of selected, graded aggregate. The resin and hardener components should be stirred separately for three minutes or until thoroughly blended. The contents of the hardener should be added to the base component and stirred with a heavy duty drill until all the components are thoroughly blended. Then slowly add the entire amount of aggregates to the resin while the mixer is still running. Partial mixing of the three components should not be allowed under any circumstances.


Pour the mixed products steadily form one side only to eliminate the entrapment of air, assuring a continuous flowing of product. It is advisable to calculate and mix enough each time quantity for one pile or multiple of pile.

The mixed product should be strictly placed within the product pot life. Watch the formwork while placing the product, if any leakage is noted, seal the leaking spot immediately.

Once the product dries, the formwork can be removed. Clean the surface by sanding it manually to remove all traces of release agent, and to provide an adhesive key with the successor recommend waterproofing system.


Tools and equipment should be cleaned with SOLVENTE 10 immediately after use. Hardened material should be removed mechanically. Spillages should be absorbed with sand or sawdust and disposed of in accordance with local regulations.


n Do not apply EPOGROUT PC EXTRA if the temperature is less than +5⁰C

n Partial mixing of the product components should not be allowed under any conditions

n EPOGROUT PC EXTRA should be placed in a thickness between 10 mm to 100 mm per layer

n Extra care should be taken when applying at high temperature as pot life of the mixed product will shorten automatically

n It is recommended to shade the working area while mixing and placing EPOGROUT PC EXTRA.
