GUIDELINES FOR INSTALLATION OF INDIAN SANDSTONE
Preparing the ground for paving depends upon factors such as site conditions, as well as the intended use of the area being paved. If the ground you are working on is firm you will only probably need to remove the turf and topsoil to a depth and allow 100mm of hardcore, and 60mm for the slab and mortar thickness's. If the ground area that you're working on is very soft or if the paved area is likely to have heavy traffic on it, you'd then need to allow for a depth of 200mm of hardcore, and 60mm for the slab and mortar thickness's.
If the area you wish to pave is going to be driven on it is recommended that a concrete slab be poured underneath the mortar bed, however an engineer may need to be consulted at this stage. In reality few areas are already level enough for immediate paving, so some areas need to be excavated whilst others need to be made up with compacted hardcore.
Note: For most paving scenarios we would recommend that you use a 25-35mm wet mortar bed on 100mm of well compacted hardcore when using natural stone
Some less experienced landscapers come across confusion about the correct way to lay natural stone! The larger surface area is the side of the slab you see when it is laid, this means that the joints between the slabs are smaller at the top than they are at the bottom. This also helps the pointing in order to get a better hold.
LAYING AND CUTTING
We recommend that whenever laying natural stone you should mix your paving
from 3-4 different packs (if laying a large area) as this will allow the colours to
blend and help to improve any shade variations which may occur between packs,
giving your patio a more natural look.
Use a wet or slightly wet mortar mix of 1 part cement to 5 parts building sand.
Start from a corner, or use a string to give yourself a straight line. Next you
should trowel five large dabs of mortar at each corner and in the middle of each
slab giving yourself a fairly full bed of mortar.
Due to the variations in thickness it is advised that you start with a thick slab and tap it down into the mortar until you find the correct level (use a rubber mallet to tap the slab down as it avoids cracking it). Once you lay the first slab lay the five spots of mortar for the next slab. You could also lay a strip of mortar where the next joint will be, this helps to minimise pointing afterwards. Ensure that you check all of the levels and falls during the laying process, you should do this by using a spirit level. This will help you to create a patio with a slight fall on it to ensure that it drains properly.
If the patio requires a lot of cutting we would advise that you hire a powered cutting tool with a diamond tipped blade. Some stones can be harder to cut than others and will require more work.
There are several methods and products in the market to help with the pointing of paving products. Air reacting jointing products (i.e. Geofix and Rompox), and the old fashioned cement and mortar mix.
We recommend that paving is laid allowing for a minimum 10-15mm joint.
If you are using a jointing product you should follow the instructions on the cover of the product, as failing to do so can result in a complete renewal of products being required again for the job. When using a cement mortar mix we recommend using a wet mix (but not sloppy) to produce a more permanent waterproof finish. Always make sure you clean the excess cement mortar mix from the paving using a sponge when the mortar is still wet, or a wire brush and some acid cleaner when the mortar has hardened.
