What is the correct sand and cement mix?

• The correct sand and cement mix depends on the specific application and requirements. It is essential to follow the recommended mix ratios provided by experts or local building codes to ensure proper bonding, strength, and durability of the mortar.

What is best to put between patio slabs?

• The best material to put between patio slabs is jointing compound or mortar, depending on the type of paving stones used and personal preference. Jointing compounds such as polymeric sand provide better flexibility and weed resistance, while mortar offers more stability and longevity.

What is the best base for laying a patio?

• The best base for laying a patio depends on factors such as soil type, drainage requirements, and personal preference. Common base materials include compacted gravel, crushed stone, or concrete. Ensure proper compaction and leveling of the base to provide a stable foundation for the patio.

Can you lay new slabs on top of old slabs?

• Yes, you can lay new slabs on top of old slabs, provided that the existing slabs are in good condition and properly leveled. However, it’s essential to ensure proper preparation of the surface and adequate bonding between the old and new slabs to prevent movement and instability over time.

Is sharp sand good for laying slabs?

• Yes, sharp sand is commonly used for laying slabs due to its coarse texture and good bonding properties when mixed with cement to create mortar. It provides stability and helps prevent movement of the slabs over time.

How do you lay a patio for beginners?

• To lay a patio for beginners, start by planning the layout and preparing the site. Excavate the area, level the ground, and compact the soil. Install the base material, such as gravel or crushed stone, and ensure proper compaction. Lay the paving slabs according to the desired pattern, leaving appropriate gaps for jointing material. Fill the joints with sand or jointing compound, and compact the surface. Finally, brush away any excess material and seal the patio if desired.

How many 600×600 slabs in 50 square metres?

• The number of 600×600 slabs needed for 50 square meters depends on factors such as the size of the slabs, the desired layout pattern, and the width of the joints. As a rough estimation, you may need around 100 to 120 slabs for a 50 square meter area.

Can you lay paving slabs with just cement?

• No, it is not recommended to lay paving slabs with just cement. Paving slabs should be laid on a properly prepared base material, such as compacted gravel or crushed stone, and secured with mortar or jointing compound to ensure stability and longevity.

Do you compact sand before laying slabs?

• Yes, it is essential to compact the sand base before laying slabs to ensure a stable and level surface. Use a plate compactor or hand tamper to compact the sand evenly and remove any air pockets, which helps prevent settling and movement of the slabs over time.
