Expansion joints in concrete can be sealed with a variety of materials depending on project requirements and the type of joint.
Some types of grout, such as epoxy grout, such as Teknobond 700 or polyurethane-based grout, have improved chemical resistance.
Superplasticizers are one of the most common and effective additives for increasing the plasticity of concrete
Expansion joints are planned gaps in a structure that allow control of deformations caused by thermal or mechanical stresses, and also reduce the likelihood of cracks and damage in concrete or stone.
In most cases, priming the concrete before applying the varnish is the desired procedure
