Dr. Fixit Crack-X Shrinkfree is a non-shrink filler for wider and structural cracks in concrete. The shrink-free behaviour is the point — an ordinary cement fill shrinks as it cures and opens a fresh gap at the edge of the repair it was meant to close.
Leakproofs by Betterwork specifies and applies Dr. Fixit Crack-X Shrinkfree as part of a complete waterproofing system. A material on its own does not stop a leak — what stops it is the right material chosen for the right defect, on a surface that has been properly prepared. That is why we deep-scan before we specify.

How it is applied
The crack is cut out to a proper profile, cleaned and dampened, then filled and compacted so no voids remain behind the face. Where the crack is still moving, this rigid fill is not the right answer on its own and a movement-accommodating treatment is specified instead.
Preparation is the part that decides whether the system lasts. Loose material and failed old coatings are removed, cracks are cut and filled, and the surface is cleaned and brought to the moisture condition the product requires before anything is applied. Skipping that stage is the single most common reason waterproofing fails in its first season, whichever brand is on the tin.
Key properties
- Does not shrink back and reopen at the edges
- Suited to wider and structural cracks
- High strength once cured
- Can be coated or plastered over
- For dormant cracks — live cracks need a flexible system
