Garden Paving Tips

For a huge zone of clearing which must be hard surfaced consider the utilization of cement laid, that is on the spot. It is perpetual, needs no support and can be formed to suit any shapes or levels. Since cement extends and contracts with changes in temperature it ought to just be laid in ranges of not more than 3 meters, around three yards square. On the off chance that the range to be cleared is bigger than this it should be separated into an example or fortified.

When clearing a little garden, in cement is likely best laid in squares set conveniently alongside each other with just a slight crevice between, conceivable loaded with sand. On the off chance that each square is permitted to dry before the following one is laid, filling the joints ought not be important. Cement can be finished in various approaches to deliver intriguing examples: drawing a solid sweeper crosswise over it when it’s about set, for instance makes a ribbed surface and brushing concrete before its completely dry uncovered the rock total in its arrangement, making a pebbly wrap up. On the off chance that you are utilizing another person to carry out the occupation, have an example arranged on the ground or in an old seed box as a guide. A complex method for utilizing as a part of cement is to lay it in an example with block, rock setts or even solid pieces in a differentiating shading.

Laying your own concrete is a comparatively cheap way to surface an area but the work is heavy and messy. It must be carefully planes and requires more than one pair of hands. The first thing to do is to calculate the volume of concrete needed, which is indicated by the chart; then decide on the correct mix for the job. For a small area you can buy bags of dry-mixed concrete, so that all you have to do is add water. Otherwise you can order ingredients and mix them yourself, either with a shovel or small hired concrete mixer. For major jobs – if you are using more than about 3 cubic meters of concrete, the most practical method is the ready mix truck that delivers the concrete and pours it by chute directly to where it will be used. If you use ready mixed concrete, have the site fully prepared, with the entire wooden frame work ready for when the lorry arrives. When it is not possible to pour it directly into the frame work, you can transport the concrete by wheel barrow. But you will need help, since the concrete must be laid within 2 hours of delivery and 1 cubic meter takes about 40 wheel barrow loads.

In situ concrete requires a firm and level surface. If the soil is fairly firm and you want a surface level with the surrounding ground, all you need to do is to dig down to the same depth as the concrete area – 100mm for a drive, 50mm for a path. With loose soil, put down a layer of rubble first and compact it with a roller; paths need 25mm to 50mm of rubble, while drives need 75mm. when laying concrete on a cracked base, first break this up and compact the rubble, as a new layer laid on top of an old base will often crack or scale.

Laying Concrete

  • In setting out the formwork for in situ concrete, prepare a base at least 100mm wider than the proposed size of the finished area of paving. Build a strong formwork from 25mm by 75mm timber, with pegs at 1 meter intervals. Check the formwork with a spirit level, allowing a drainage slope of 6mm in 300mm. a 20mm thick block of wood placed under the batten supporting the spirit level will give the correct slope for a path 1 meter wide.
  • Pour the concrete into the formwork, getting it as near as possible to its final position so as to minimize further handling. Use a rake or shovel to spread the mix evenly, leaving about 25mm above the formwork to allow for compaction.
  • Compact and level the concrete with a heavy plank. Lift the plank a little and then drop it, moving it along half the thickness of the plank each time; repeat this process and finally remove excess concrete by sliding the plank from side to side with a sawing action.
  • When the surface water has evaporated, finish the concrete with a wooden float. Move the float in sweeping arcs to bring the fine particles to the surface.
  • If you want a rough, non-slip texture, drag a broom across the surface of the concrete. The stiffer the bristles, the rougher the final texture will be.
  • The aggregate in the concrete can be exposed to give a pebbly surface. When the concrete begins to harden, hose it gently and brush away the top layer of cement. Cover newly laid concrete with damp sacking, waterproof building paper or polythene sheets. After about four days in warm weather and up to ten in winter, the concrete should have set sufficiently to take light weights, but keep heavy loads off for another four to ten days just to be safe.

Concrete slabs

The pre-cast slab is by far the most commonly used paving material, though it is more expensive than concrete laid. Used sensitively over a limited area, without too much pattern and little colour, it is an excellent material, being hard wearing and easy to clean. Concrete slabs also mellow fairly quickly and their colours even fade; this is often a blessing, for the over patterned terrace is as demanding to walk on as the over patterned carpet inside. Check the colour of any slab you want, seeing it both wet and dry.

Paving slabs come in most sizes and shapes: squares, rectangles, circles and even pre-arranged crazy paving in a variety of different textures. Patterns can then are made up as desired but remember that a paving pattern is only part of a larger design and it should not be allowed to disrupt the whole, so keep it simple.

Depending on the wear that the terrace or path will take, slabs can be laid either in sand or in mortar. Another method when laying them in sand is to use four to five evenly spaced spots of mortar for each slab. They should always be laid to fall away from any structure allowing the surface water to run off. Make sure you lay the slab the right way, with the coarse textured side upwards. If the paving abuts the lawn, set the slab 10mm below the grass to allow form mowing.

Interlocking paving blocks used for road construction in some countries for years have recently been adapted for home landscaping. They are ideal for use in the garden, on a terrace or a drive. They are made of higher quality concrete and can be laid flush in an interlocking pattern without mortared joints. Their virtue is that they can take considerable weight and do not creep laterally, as smaller paving materials tend to do with weight upon them. Concrete blocks are available in various colours and are textures like a brick, patterns varying according the manufacturer.

Kerbing Paved Areas

A kerb may not be necessary, if the paving itself holds back the earth sufficiently. A kind of mini retaining barrier is needed only where there is an abrupt change of level between path and bed and where you cannot simply excavate earth form below the paving and throw the soil back into the bed.

If possible, make a curb out of the same material as the paving. Builders, left to their own device, tend to kerb the edge of any pavement with a heavy piece of concrete whether it complements the paving material or not. The advantage of concrete kerbs is that they are available in fairly long runs. They can work well if the path is paved with concrete slabs, for instance, or where concrete forms part of the paving pattern.

A concrete kerb looks better placed so that the square edge of the kerb is up right, with the rounded edge in the ground. Additionally foundations should be placed underneath a kerb, or the kerb itself set higher than the main paving so that it effectively retains it (the smaller the paving unit the more essential this is).
