Beyem Thick Grout

Beyem Thick Grout

One-component, shrinkage compensated and slightly expansive fluid mortar for anchoring and filling  in thick layers.

About this product

BEYEM THICK GROUT is a one-component, shrinkage compensated and slightly expansive fluid mortar for fillings and precision anchorages in thick layers. Formulated with special cements, selected aggregates, to improve adhesion and  initial and final mechanical strengths. 

  • Easy to mix and  apply.
  • High initial and final mechanical strengths.
  • High adhesion to concrete, mortar or steel  reinforcement.
  • Excellent flow properties. High self-levelling and filling power.
  • Free of chlorides and organic fibers.
  • Very low shrinkage behaviour. Slightly expansive.
  • Free of aggressive substances for concrete and steel reinforcement.
  • Both internal and external use. 

Anchoring of reinforcement steel bar, concrete or machinery. Reinforcement of concrete elements through formwork. Filling machinery bedplates. Fixing bolts. Filling cavities, voids, gaps and recesses in concrete. Filling by pouring under support plates ensuring perfect load transmission.


BEYEM THICK  GROUT is suitable for:

  • Concrete  ( floors, screeds, formworks) 
Preparation of substrates

Concrete must be free from dust, loose material, surface contamination and materials which reduce  bond or prevent suction or wetting  by anchoring and filling materials. Steel reinforcements must be free of rust, grease, oil and other adhesion impairing contaminants (Sa21/2 degree). Where necessary, concrete  must be cleaned by sandblasting, high pressure water jetting or other approved mechanical methods that do not cause vibration or impact, to leave a clean and keyed surface. Rusty exposed reinforcement must be cleaned by    metal brushing or sandblasting. Absorbent substrates should be previously wetted until they are saturated, preventing waterlogging, and applying the mortar  once the surface has a matt appearance.

Smooth, slightly absorbent or very damaged substrates should be treated to obtain a surface with minimum guarantees of roughness and tensile strength. Minimum roughness of at least 5 mm. For more information regarding substrate preparation, refer to the recommendations provided in EN 1504-10.

Instructions for use

Mix manually of mechanically BEYEM THICK GROUT with  2,75-3,50 l per bag of clean water until a homogeneous, fluid  and lump-free consistency is obtained. Mixing water must be between 11-14 % by dry mortar weight, depending of  consistency (pourable, flowable)  and mechanical strengths needed. Do not add more water to the mortar than the recommended amount and do not remix.

Pour the mixed grout into the header box/hopper ensuring continuous grout flow during the complete grouting operation to avoid trapping air. Use steel banding or chains to assist flow where necessary.

For filling under plates, an air outlet should be provided, so that air can come out easily during the filling

with the product. On large surfaces, vibrating with a rod or ramming into place with hardwood tamping tools and mallet is recommended. BEYEM THICK GROUT can be applied in thicknesses not less than 30 mm and not more than 100 mm per layer. Finishing can be done with trowel or float as soon as the mortar has started to stiffen. 

Cautions and recommendations
  • Do not apply below 5ºC or above 30ºC.
  • Do not apply when there is risk of frost, rain, strong wind or direct sunlight.
  • Do not add water in excess of the recommended dosage .
  • Protect the mortar applied of early dehydration, using suitable  curing methods. The curing operation in humid environment is essential for at least 24 hours after application.
  • This product is not recommended for surface levelling.
