 Our main brands

We offer multi-purpose non-shrink grouts, for structural and non-structural applications, including precision grouting, base plates, pre-cast components, machinery and equipment bases, anchor bolts, concrete repair, keyway joints, load bearing pads and other non-shrink applications.

Product lines featured in our construction grouts and concrete repair range include:

  • Class A Construction Grouts
  • Class C Construction Grouts
  • Concrete & Patch Repair

A high quality blend of Portland cement and non-shrink additives mixed with water produces a durable, high-strength material useful for grouting and general concrete applications on both indoor and outdoor projects.


Bostik cementitious grouts are examples of how formulated products offer specific qualities to the construction industry.

Grout Classification 

Cement has a natural tendency to shrink during curing. There are two common forms of shrinkage:

  • Early age shrinkage (also called plastic shrinkage) is predominantly due to water evaporating from the matrix
  • Post hardening shrinkage (also called drying shrinkage) is a result of ongoing chemical reactions and hardening

Class A grouts (also referred to as General Purpose) are non-shrink during the plastic state

Class C grouts (also known as Performance Grouts) are shrinkage compensated (non-shrink) during both the plastic and post hardened state

Applying the right floor primer can greatly improve adhesion of self-levelling underlay to subfloors resulting in a more secure and durable installation. Primers are materials used as a preparatory coating to enhance adhesion of overlaying compounds. They regulate absorption rate of porous substrates and improve adhesion to non-porous materials. Various impervious substrates are becoming a norm. Uses of appropriate primers are necessary to ensure good bonding to these substrates. Failure to do so can lead to de-bonding of coverings.


Structural repair and maintenance is an integral part of concrete repair and patch work, which can occur on both horizontal and vertical surfaces across a range of structural elements.

Bostik’s range of concrete and patch repair have been created to specifically meet the needs and requirements of the job without compromising on quality and performance. It consists of heavy duty, polymer modified mortar, fairing mortars as well as rapid setting concrete.
