VoidFiX Pro: hollow tile repair without lifting a single tile

If you can hear hollow tiles when you tap them, or worse, if they are starting to crack, you do not have to rip up the floor. VoidFiX Pro is a German-engineered, single-component elastic injection compound that flows deep beneath loose or hollow tiles, re-bonds the tile bed, and restores full structural integrity. No demolition, no mess, no retiling costs.

At just £49.99 for 1 litre, VoidFiX Pro costs a fraction of lifting ceramic or porcelain tiles, disposing of old adhesive, sourcing matching replacement tiles, and relaying the entire floor.

Made in Germany

Manufactured in Germany to exacting standards, VoidFiX Pro is a professional-grade formulation with ultra-low viscosity. It flows into cavities that thicker products cannot reach, giving a thorough fill every time.

Applied through drilled grout joints using a syringe or pipette, the fluid penetrates deep into the void before curing to a permanently elastic state. Repeated application is possible until the cavity is fully saturated, preventing future movement, hollow sound, and costly tile breakage.

VoidFiX Pro also seals fine hairline cracks in mosaic and terrazzo floors, protecting against moisture ingress and further deterioration.

Application requires a syringe. See the SUBSTRAT VoidFiX Injection Syringe (sold separately).
