Cobble Setts are a fantastic choice for creating driveways or garden spaces that combine durability and eye-catching style. These timeless paving stones not only look great but also stand up well to the test of time. Interested in adding Cobble Setts to your home? With the right preparation and method, you can achieve a professional finish that lasts for years. Here’s your step-by-step guide to laying Cobble Setts.
Step 1: Get Your Materials and Tools Ready
Before starting, gather everything you’ll need. Here’s a handy checklist:
Materials:
- Cobble Setts (ensure you have enough for your space)
- MOT Type 1 sub-base material
- Sand, cement, and water
Tools:
- Mixer or bucket for mortar preparation
- Trowel
- Wheelbarrow
- Pointing tool
- Spirit level
- Plate compactor
- Rubber mallet
- Spray paint
- String lines and stakes
- Measuring tape
- Rake and spade
- Protective gloves
Unsure how much material your project requires? Don’t hesitate to consult an expert for guidance.
Step 2: Mark and Prepare the Area
Start by deciding on the boundaries of your paved area. Use spray paint to clearly mark the space. Once marked, dig to a depth of around 230mm, removing any weeds, vegetation, and topsoil. Smooth out the ground as much as possible—it should be at least 150mm below your home’s damp-proof course.
Step 3: Level and Compact the Ground
Set up string lines across the marked area. These will help you spot any uneven sections. Remove peaks and troughs using a rake, then compact the ground using a plate compactor. This creates a stable foundation for your Cobble Setts.
Step 4: Lay the Sub-Base
The sub-base forms the backbone of your paving area, so don’t skip this step! Add the first layer of MOT Type 1 sub-base material to a depth of about 75mm. Use the plate compactor to compress it firmly. Repeat the process for a second layer to create a total depth of 150mm. Be sure the surface has a slight slope to encourage proper water drainage.
Step 5: Prepare and Apply Mortar
Now it’s time to mix your mortar. Combine three parts sand, one part cement, and one part water to create a wet, workable consistency. Spread the mortar generously over the sub-base, leaving enough space for the Cobble Setts. Typically, you should aim for a 15-30mm gap when the mortar is compacted.
Step 6: Lay Your Cobble Setts
Begin placing your Cobble Setts onto the mortar, leaving about 8 to 15mm of space between them. Use a rubber mallet to gently tap each sett into place, ensuring a snug, even fit.
Once the Cobble Setts are laid, mix one part sand with one part cement to create a jointing mixture with a smooth, wet consistency. Fill the gaps between the setts with this mix, using a pointing tool to compact it firmly.
Step 7: Allow Time to Set
After finishing, leave the area undisturbed for 24 hours to allow the mortar to cure. If rain is forecast, consider covering the area for additional protection. For heavier items or vehicles, wait a little longer before use to ensure everything sets securely.
