Refresh your patio in time for summer with U-Can’s guide to fixing a loose slab 

Firstly, you’ll need to chip away the existing grout in order to remove the loose slab. Do this using a hammer and chisel and brush away any debris. Then, use a spade to lift the slab out of place. If your patio was laid on a mortar bed then there might be some leftover mortar on the bottom of the slab or on the ground. Use the hammer and chisel to remove any mortar to create an even surface that will ensure the slab is secure once it’s been laid. If it was laid on a sand base, remove some sand to the depth of about 30mm.

Step 1

1 Take the U-Can mix in the bag mortar. Unscrew the spout and carefully pour in 2.5 litres of clean water. Squeeze out any excess air, screw the cap back on and lie the bag down flat on the ground.


Step 2

2 Knead the bag like you would a dough to ensure that the water is evenly distributed. Flip the bag over a couple of times to make sure that the mortar is thoroughly mixed.


Step 3
3 Now it’s time to re-lay the slab. Cut open the top of the bag of mortar along the dotted line and add five blobs onto the ground – one in each corner and one in the middle. Use a trowel to spread it evenly, the weight of the slab will help once it’s re-laid.


Step 4

4 Carefully lay the slab and tap it into place with a rubber mallet. If the slab sits above the level of the rest of the patio, lift it up and remove some of the mortar until you’re happy with its position.


Step 5

5 If you have a spirit level, use this to check your newly laid slab before using a pointing trowel to fill the gaps between the slabs with excess mortar. If you don’t have a pointing trowel, the back of a trowel handle will do the job. Leave the mortar for a few hours until fully dry before stepping on your newly-secured slab.
