How to Fix Loose Floor Tiles Without Removing Them
Quick answer: You can usually fix a loose floor tile without removing it, as long as the tile isn't cracked and the floor underneath is sound. Make a small access point in the grout line next to the tile, inject a flowable bonding adhesive into the hollow space underneath, weight the tile while the adhesive cures, then regrout. Tiles that are lifting across a whole area, sitting on a damp or broken subfloor, or cracked right through need a different repair.

How to tell if a floor tile is loose
- It rocks or clicks when you step on one edge.
- It sounds hollow when you tap it with a coin or the handle of a screwdriver, compared with the tiles around it.
- The grout around it keeps cracking or crumbling, even after regrouting.
- One edge sits higher than its neighbours.
A hollow sound on its own isn't proof the tile is loose. Some tiles were laid with gaps in the adhesive and never move. If the tile doesn't move and the grout is intact, keep an eye on it rather than repairing it straight away.
Why floor tiles come loose
| Cause | What you'll notice | Can you inject? |
|---|---|---|
| Not enough adhesive under the tile when it was laid (gaps or "dot and dab") | Hollow sound, slight rocking, cracked grout | Yes, this is what injection repair is for |
| Floor movement, such as a timber subfloor flexing | Several loose tiles in a walkway, grout cracking in lines | Yes, but stiffen or secure the subfloor first or it will happen again |
| Water getting under the tiles | Loose tiles near showers, baths or sinks; staining or damp | Not until the leak is fixed and the floor has dried out |
| Heat or expansion with no movement joints (tenting) | Tiles lifting up into a ridge across a whole area | No, this needs lifting and relaying with movement joints |
| A cracked or broken tile | Visible crack through the tile | No, replace the tile |
How to fix a loose floor tile without removing it
This is the method for an intact loose or hollow tile on a sound floor, using Injectafix. Always follow the instructions supplied with the product for hole size, tip preparation and curing.
What you'll need
- Injectafix Pro 300ml with a caulking gun, or Injectafix Easy Squeeze, which needs no gun
- A drill with a suitable bit, as specified in the instructions
- A vacuum or brush to remove dust
- Clean-up wipes for excess adhesive
- Something heavy and flat to weight the tile
- Matching grout, such as Twist & Grout
Step 1: Check the tile and the floor
Confirm the tile is intact and the floor beneath is sound and dry. Check for underfloor heating pipes or cables, and any waterproofing or tanking membrane, before you drill.
Step 2: Make an access point in the grout line
Following the instructions for your Injectafix format, make a small access point through the grout line beside the loose tile. Control the depth carefully and don't drill into the subfloor.
Step 3: Clear the dust
Vacuum or brush out the access point so dust doesn't block the adhesive or weaken the bond.
Step 4: Inject the adhesive
Inject slowly into the void under the tile. Stop if the tile starts to lift. You want to fill the hollow, not push the tile up.
Step 5: Weight the tile
Press the tile level with its neighbours and weight it while the adhesive cures, as directed on the pack.
Step 6: Clean off any excess straight away
Wipe away adhesive on the tile surface before it hardens.
Step 7: Leave it to cure
Keep foot traffic off the tile for at least 24 hours, or longer if the pack says so. Check the tile is solid before walking on it normally.
Step 8: Regrout
Once the tile is firm, rake out the old grout around it and regrout with a matching colour. New grout won't hold over old grout, so remove it first.
Hollow tiles: repair now or leave them?
Repair a hollow tile if it moves, if its grout is cracking, or if it's in a heavy walkway or under a heavy object. Hollow tiles under load tend to crack eventually. If a hollow tile doesn't move and its grout is sound, it's safe to monitor it.
Cracked grout is often a loose tile problem
Grout fills the joint; it doesn't hold the tile down. If a tile is moving, new grout around it will crack again within weeks. Fix the tile first, then regrout. Read why grout cracks.
Loose bathroom floor tiles
Find out why they're loose before you repair them. Check for leaks around the shower tray, bath, toilet and sink, and for soft or damp flooring. If water has got under the tiles, fix the leak and let the floor dry out fully first. If the floor has a waterproof membrane, make sure you don't drill through it.
When to lift and relay instead
- Tiles are lifting into a ridge across a whole area (tenting).
- The tile is cracked right through.
- The subfloor is soft, rotten, crumbling or wet.
- Most of the floor sounds hollow and is moving.
Frequently asked questions
Can you fix loose floor tiles without removing them?
Yes, if the tile is intact and the floor beneath is sound. A flowable adhesive injected through the grout line fills the void and re-bonds the tile without lifting it.
What's the best adhesive for loose floor tiles?
For a repair without lifting the tile, use an adhesive designed to be injected: it has to flow into a thin void and bond to both the tile and the floor. Standard tile adhesive is too thick to inject, so it only works if you lift the tile and relay it.
How long before I can walk on a repaired tile?
Keep traffic off it for at least 24 hours, or longer if the pack instructions say so.
How much adhesive will I need?
It depends on the size of the void under the tile, not the size of the tile. Each Injectafix pack is 300ml; check the product page for pack options.
Will regrouting fix a loose tile?
No. Grout doesn't bond the tile down, so the new grout will crack if the tile keeps moving. Re-bond the tile first.
