FAQs

What is the weight of each slab?

Each 3x2 slab weighs approximately 71kg.

What tools do I need for installation?

You'll need a shovel, rake, wheelbarrow, plate compactor, spirit level, rubber mallet, trowel, pointing tool, and lifting equipment or assistance.

What is MOT Type 1?

MOT Type 1 is a sub-base material used to provide a solid foundation and improve drainage for paving.

How should I mix the mortar?

Mix the mortar using a ratio of 3 parts sharp sand to 1 part cement. Add water gradually to achieve a semi-dry consistency.

What gap should I leave between the slabs?

Leave a 10 mm gap between each slab for expansion and to allow for pointing.

How long should I wait before using the paved area?

Allow the mortar to set for at least 24 hours after laying the slabs, and then let the pointing mortar dry for another 24 hours before using the patio.

Can I cut the slabs?

Yes, but it's recommended to use appropriate tools for cutting concrete slabs. Consider hiring a professional if you're not experienced.

How do I maintain the paved area?

Regularly sweep the surface to remove debris and use water and mild detergent for cleaning. Check and repair any damaged joints as needed. Consider applying a sealant for added protection.

Troubleshooting

Slabs are uneven or wobbly after installation.

Check and adjust the mortar bed under each slab. Ensure the sub-base is properly compacted and level. Re-level the slabs by adding or removing mortar as needed.

Water pooling on the surface after rain.

Check the slope of the paving. Ensure there's a slight fall (slope) of around 1:80 away from buildings. Re-level slabs to correct the drainage.

Mortar is cracking or crumbling.

Ensure the mortar mix ratio is correct. Repair the joints with a new mortar mix and allow them to dry properly.

Slabs are stained or discolored.

Clean the slabs with a mild detergent and water. Consider applying a sealant to prevent future staining.

Difficulty lifting and positioning slabs.

Use lifting equipment such as a slab lifter or seek assistance from another person. Always lift with your legs and not your back.

Setup, Compatibility & Care

Setup

  1. Prepare the Area: Clear the area of all plants, grass, and debris. Dig out the ground to a depth of 150–200 mm (6–8 inches). Ensure a slight slope for drainage.
  2. Lay the Sub-base: Add a 100–150 mm layer of MOT Type 1 sub-base and compact it firmly.
  3. Mix the Mortar: Mix 3 parts sharp sand to 1 part cement with water to a semi-dry consistency.
  4. Lay the First Slab: Apply a 30–40 mm thick mortar bed, position the slab, and level it using a rubber mallet and spirit level.
  5. Lay Remaining Slabs: Leave a 10 mm gap between each slab and check for level.
  6. Let the Mortar Set: Lightly spray with water and let the slabs set for at least 24 hours.
  7. Fill the Joints: Use a 4:1 sharp sand to cement mix, fill gaps, and smooth joints.

  • Sub-base: Compatible with MOT Type 1.
  • Mortar: Use a mix of sharp sand and cement.
  • Spacers: Use spacers or a piece of timber cut to size to keep spacing uniform.

Care

  • Cleaning: Regularly sweep the surface to remove debris. Use water and mild detergent for cleaning.
  • Maintenance: Check and repair any damaged joints as needed. Avoid using harsh chemicals.
  • Protection: Consider applying a sealant to protect against stains and weather damage.
