What types of concrete damage can Topseal repair?
Depending on the condition, repair work may include non-moving cracks, chips, spalls, divots, holes, damaged joint edges, failed patches and localized surface deterioration. Structural movement, extensive instability or active water entry may require additional specialists or work outside a flooring repair.
Can every concrete crack be permanently repaired?
No repair can guarantee that concrete will never crack or move again. A static crack can often be prepared and filled, but an active crack may continue moving. The likely cause, evidence of movement and surrounding slab condition should be evaluated before selecting a treatment.
What is the difference between a static and dynamic crack?
A static or dormant crack is not expected to experience movement significant enough to disrupt the repair. A dynamic or active crack is still being affected by settlement, heaving, vibration, thermal change or another movement mechanism. Dynamic cracks generally require flexible treatment or must be honoured through the flooring system.
What does it mean to honour a concrete joint?
Honouring a joint means allowing it to remain functional through the completed flooring system instead of rigidly covering it. Expansion, construction and isolation joints may need to be carried through the new floor and sealed with a material suited to the expected movement.
Can control joints be filled before a coating is installed?
Some non-moving control or contraction joints can be cleaned and filled flush with a compatible rigid or semi-rigid material. The joint type, age of the slab, expected movement, traffic and flooring system should be reviewed before it is covered.
Will a repaired crack show through a new floor coating?
A properly treated static crack may remain concealed, but future slab movement can cause a crack to reflect through the new flooring. Flexible membranes or reinforcement may be considered for some conditions, but they cannot overcome unlimited or continuing structural movement.
When should a crack be evaluated by an engineer?
Cracks accompanied by heaving, settlement, displacement, recurring movement, significant water entry or possible structural distress should be evaluated before a flooring repair proceeds. Topseal’s repair work should not be presented as a substitute for structural diagnosis.
Can damaged joint edges be rebuilt?
Yes, localized joint-edge damage can often be cut back to sound concrete and rebuilt using a compatible repair material. The filler or sealant within the joint must still be selected according to expected movement and traffic.
Can spalled or pitted concrete be repaired?
Localized spalls, pits and divots may be repaired when loose material is removed and the remaining concrete is sound. The depth of damage, exposure and intended floor system determine whether an epoxy mortar, polyurethane repair material, cementitious repair product or another solution is appropriate.
Can concrete repairs correct an uneven floor?
Localized repairs can rebuild depressions, damaged transitions and some low areas. Correcting widespread flatness, elevation or drainage problems may require concrete grinding, self-levelling material, sloping work or a larger resurfacing system.
Does moisture affect concrete repairs?
Yes. Active water entry, saturated concrete or moisture vapour can affect the bond and performance of some repair and flooring materials. The moisture source and product limitations should be reviewed before the repair is completed or coated.
Can repairs be completed before epoxy flooring?
Yes. Concrete repairs are commonly completed after mechanical preparation and before the primer or body coat is installed. The repair material must be compatible with the concrete, preparation method and complete flooring system.
How long do concrete repairs take to cure?
Cure time varies significantly by product, repair depth, temperature and exposure. Some fast-curing materials can be recoated or returned to traffic relatively quickly, while deeper or cementitious repairs may require more time. The actual schedule should follow the selected manufacturer’s instructions.
