Garden paths: walkway slab and stone blocks (Part 2)
STEP 2. Your lay-out
Plan the future path or a platform on district: draw contours; hammer pegs on bends and turns; pull on them a cord almost at ground level.
STEP 3. Preparation of a line
Now it is necessary to take out the top fertile layer of the ground and on what depth? So that the gravelly-sandy pillow (lining) plus a stone blocks was located. Thickness of a pillow depends on loading on the future path. If it will be foot then the thickness of???? 15 cm. will be enough, but if the cars will be driven trough the path or a platform, the thickness should start from 20 cm.
STEP 4. Stacking of the pillow
Pillows for a stone blocks and walkway slab are prepared differently.
Stone blocks: the bottom layer is complicated from gravel (rubble, slag), top layer - from sand.
Under a tile the third, uppermost layer is required: a mix of cement and sand at the rate of 1 cube and a meter of sand plus 100 - 150 kg of cement. Sand and cement should be mixed up “till dry “. This dry mixture will absorb moisture from the ground! Thickness of cement layer should be about 2 cm.
STEP 5. Pressing
The pillow may be pressed with different means.
So that the future path “has not parted”, lay a plastic border lengthways of its contours and then it can be hidden with a lawn.????
Lay stone blocks on 1 cm above the final level. The backlash between separate “bricks” should be about 1 - 2 mm. Then the dry sifted sand is strewed on a path.
When you are buying a walkway slab, you should learn its basic characteristics, for example, “absorption of moisture - 5 - 7 %”, “frost resistance - 100 cycles” etc.
