For a patio measuring around 10 metres squared, you should expect to pay anywhere from £550 to £1,100 for brick or concrete slabs. Premium options tend to range from £900 to £1,200 for slate or £800 to £1,350 for a stone patio.
Although building your patio over a concrete slab helps to ensure it won't settle unevenly later, you can build a patio without cement. By laying flagstone, tile, brick or other sturdy, flat pavers on a well-prepared base, your patio will be less expensive and more water-permeable.
An 8 square metre patio with a simple design should take approximately 2 days for two people. This includes marking out the area, digging down to the required depth or removing existing paving or decking, laying the sub-base foundation, mixing and applying the mortar, laying the slabs and finally filling in the joints.
Below 40 °F to 32 °F (4.4 °C to 0 °C) Do not lay masonry units having either a temperature below 20 °F (−6.7 °C) or containing frozen moisture, visible ice or snow on their surface. Remove visible ice and snow from the surface of existing foundations and masonry to receive new construction.
The layer of sand should be from one to one and a half inches thick. The sand also needs to be dry, not wet. The layer of sand can be smoothed with the edge of length of board, such as a 2x4.
During extremely cold weather concrete (particularly fresh and early age concrete) can be severely damaged by frost and ice. When fresh concrete cools below 0ºC the water in the mix freezes and expands which causes cracking internally and blistering of the surface.
A misty drizzle or light rain when the air temperature is above 40 degrees Fahrenheit actually is beneficial. Mortar should be kept moist for 36 hours to allow it to fully cure. However, a heavy rain may wash the lime out of the mortar, weakening the bond between the bricks and the mortar.
I've just laid my patio on to a dry mix - works quite well. The ratio can be as low as 1:10 (1 cement, 10 sharp sand), or as high as 1:3, depending on the amount of foot traffic you expect, and what the sub base is like.
We recommend installing your porcelain paving on a wet mortar bed of “6:1” grit sand to Portland cement or a concrete bed. Do not “butt joint” your porcelain paving. We recommend using a 4mm minimum gap to avoid chipping edges and the use of “tile spacers” to create uniform spacing.
Dig down between 6″ and 10” when creating a base. If there are problems like inferior soil or inadequate drainage at the base, dig down further. Use processed gravel as a base underneath the stones to maintain their evenness. Compact the gravel incrementally as you go up to create a stable, secure base.
The paving needs a slope or fall of around 1:60, i.e. 17mm of fall for every metre width or length of the patio. Use one taught string line to guide alignment along the length of the paving, and a second along the breadth.
Yes, you can use our jointing compound with porcelain tiles, in fact some specialist suppliers only recommend EASYJoint for jointing them! Porcelain is impermeable (it will not allow water to pass through it) so follow our instructions for use with porcelain tiles.
If it rains during the laying process, don't worry. As can be gathered water does not damage the product. 2. Very heavy rain may spoil any finish you have applied to the joint, so it may be necessary to go back and re-point the joint.
LAYING ON A CONCRETE SUB-BASE.Minimum fall over the area should be a ratio of 1:50 or 20mm for every metre. Do not lay pavers on a sand bed where there is a concrete sub-base. Step 3: Pavers should be laid to form a smooth finished surface by using a level and LIGHTLY tapping with a rubber mallet when being laid.
Here's why: dirt shrinks by 30% when compacted. That means, if you backfill with dirt, your hardscape will settle 30%. This becomes an issue because, if you backfill with 10″ of dirt, your pavers will settle around 3″ over time. However, if you properly lay a gravel base, you'll essentially eliminate settling.
When waiting for concrete to dry, keep these timeframes in mind: 24 to 48 hours - after inital set, forms can be removed and people can walk on the surface. 7 days - after partial curing, traffic from vehicles and equipment is okay. 28 days - at this point, the concrete should be fully cured.
It's not a difficult job, so put aside a weekend and you'll soon be entertaining friends, or enjoying a well-earned rest on your new patio surrounded by pots and plants. Need some inspiration?

According to several paver manufacturers, paving blocks can be installed on top of concrete without mortar if you first lay down a 1/2″ to 1” bed of coarse sand. Drainage: The biggest problem with laying pavers over a concrete slab is the inability for water to drain through the blocks and down into the earth.
Ideally it wants to sit 15mm in the mortar. Repeat this process, leaving a 10-15mm gap between each paving slab, until your patio is covered. Once you've laid your patio, spray the whole area with water until it's completely saturated, and leave it to set for at least 24 hours.
Any type of paver is appropriate for use when covering up an old patio, as long as the stones fit together and create a tight surface. This includes flagstone, brick or natural paver stones; however, if you plan to use mortar, bricks should not be used if the existing surface is asphalt.
