Bricklaying in Cambridge

When it comes to laying of bricks, it is essential to get the right mortar mix. It is vital, be it for construction or maintenance projects, so far mortar is required. There are several materials incorporated in getting mortar which includes both cement and sharp sand, soft sand or plasterer’s sand and lots more. Here, we are going to look at the right ratio for cement and sand mix in bricklaying.

Cement include ingredients such as iron, aluminium, as well as silicon and it is mainly used for mortars like aerated cement mortar, Portland cement mortar and gauged mortar. Sand, on the other hand, comes in different forms such as sharp sand, soft sand and plasterer’s sand. The sharp sand consists of a larger grain size than the others and is usually incorporated in the construction areas that requires more strength as well as flexibility. Soft sand is the most common one used in mortar and it’s also referred to as bricklayers’ sand. These are used to make all types of mortar. Finally the plasterer’s sand which neither has the sharp sand’s coarseness nor the fineness of the soft sand, but can also be used for any form of mortar.

Cement and sand mortar is used for a plethora of bricklaying jobs serving as a glue for bricks, walls and pillars, while also repairing or maintaining old listed buildings. The preferred ratio here is 1:3 to 1:5 of cement and building sand. Meanwhile, to get a sand cement mix, essential materials that are required includes water, soft building sand as well as cement. However, you must also note that a sand and cement mortar is not used for structural projects, rather a concrete ratio is used.

Sand is a very important element in bricklaying as far as a mortar mix is concerned. Generally, the quality of the sand is the major factor determining the quality of a plaster mix or mortar mix. It’s recommended that the sand should have enough ‘fines’ (- 75 micron material) to get a good plastic mix with a water content that’s less than 350 litres/m3. Generally, a mortar mix or plaster mix is made within the range of one bag of cement to 200 to 300 litres of damp sand.

Apart from experience the next best indicator of the quality of sand is a field test. In other words, if you do not have the required training or experience in bricklaying, the best bet to determine the amount of sand for a good quality mix is by carrying out a field test. Let’s have a look!

• Get about 50kg of sand and air dry it.

• Scoop 25kg of the sand, 5 kg of cement as well as litres of water ( with 1 litre and 1.5 litres of the water in different containers).

• Mix the cement and sand to form a smooth, uniform and consistent colour.

• One after the other, mix the the sand - cement mixture in the three quantities of water. Do this until you’re able to achieve a mix that’s workable enough to use as plaster.

With that done, you should take note that if 5 litres of water is sufficient then the quality and quantity of the sand is perfect. If you’d require 6 litres of water to get a mix workable as a plaster, then both the quality and quantity of the sand is average. However, if you’d need 7 litres of water to get a mix workable as a plaster, then the quality of the sand is poor. Any requirement of water above 7 litres implies a very poor quality of sand.

Do you want your house to be built using brick? Or perhaps you just require the professional services of a bricklayer. Regardless of your bricklaying needs, the cost charged depends on each job as every job is unique. Bricklayers generally look at each task individually and charges based on the complexity of each. We’ve put together this guide to give you an idea of the costs charged by bricklayers. Let’s have a look!

Generally, bricklayers charge either based on a daily rate or a fixed price for a particular amount of bricks ( usually a thousand bricks or 10 - 12 metres square). On the average, an experienced bricklayer can charge within a range of £150 to £200 daily rate and if a labour is needed for the job, an additional £60 to £100 may be included to get the job completed in a quick and fast manner. If the quoting is done based on the number of bricks to be incorporated, then a thousand bricks will be quoted in between £350 to £450 which should be completed in a couple of days.

You should however take note that most times, the bricklayer’s cost will depend on the amount of work involved in the project. As a result, a more tedious and challenging project will most definitely cost more than a simpler one. Examples of some difficult projects that’s likely to cost more are hard to reach areas, difficult sites as well as second storeys which are considered to be more challenging than single storey buildings. What’s more? The complexity of the project is also a great cost factor. While some projects are basically direct and straightforward, others involve curves and more complex designs which will ultimately make the cost jump up.

Well, just like many other team work, a bricklayer is only as good as his supporting cast. And a hard-working labourer should be able to keep three bricklayer gangs happy. But even when he gets to serve just one bricklayer, the site conditions and nature of the wall can also play a huge role in determining the number of bricks that can be laid within 24 hours.

With the best possible site condition, hard-working labourer and best scenario with no pillars, no face brick, long straight wall and no wall ties, a well trained bricklayer should be able to lay within a range of 800 to 1100 bricks all day long. However, you rarely get walls like this as there is always going to be some corner or curve somewhere which usually takes some time to get right. Furthermore, once the bricklayer has laid up to 5 feet, there’ll be a need to get some lift. From that point onwards, the job understandably gets slower and tougher - meaning there’ll most definitely be a face brick.

In addition, there are multiple other factors that can affect the number of bricks that can be laid in a day. Sometimes its the complex designs or weather that’ll determine the daily rate.

With the aforementioned factors and more realistically, on a good day and great site, an expert bricklayer should be able to lay about 500 to 800 bricks in a day. This is generally a very good target, but of course you never can tell with the reasons above and other factors that are simply beyond the control of the bricklayer. If you have a project and want it completed as soon as possible, you can pay the bricklayers based on the number of bricks laid to increase their efficiency.
