I Suppose, just like I was a few years back, which you’ve stood out admiring the garden that you painstakingly put together from scratch, and thought a nice wall round it would add the finishing touches. The following guide is supposed to help with the foundation for a wall, as, believe me, even if this isn’t done correctly, the wall will not last for long. The tools you will need include a spade, maybe a pickaxe for tougher floor, series lines, levelling plank, and spirit level.
Before starting to dig any trenches, But there are a couple of factors to be taken under account. You shouldn’t dig some trenches too close to the home, as they could undermine the building. This is especially so in the case of older houses, where concrete may not have been used from the foundations. Also, consult your regional Authority to see if you need planning permission. I have heard of instances where they have insisted on walls being demolished due to the simple fact that planning permission was not sought beforehand.
For single thickness walls, which are 100mm For dual thick walls, you will need to dig out a trench about 450mm (18in) broad. Remember that to get one thickness wall over 450mm (18in) high, you will have to build piers along with it every so often to fortify it. Those ought to be around 1.8m (6ft) apart, and you ought to widen the trench from 200mm (8in) to accommodate them. Dig down about 350mm (14in) or further until you locate hard ground. You should begin the brickwork below ground level, so the top of your concrete should be placed accordingly. If it’s going to be a rather long wall, then it may be worth your while employing a jump. You can get rid of the soil straightaway, so it will not be on your way in the future. If the floor has a slope inside, you’ll need to step the foundations–work out the height and the duration of each step using the size of the bricks that you’re likely to use, and letting a little extra for the mortar joints and beds. If you’re likely to really have a 90 degree angle in your wall, use a builder’s square, (remember your geometry from schooldays), which has sides of 3:4:5
For the Concrete, you can use ready combination, but it can be expensive if you’re doing a large place. It is possible to easily mix your own, with ballast that’s made up of gravel and sharp sand along with regular cement. For a little bit of concrete, it is possible to mix it by hand, but when there is a large area, it’s probably much better to seek the services of a mixer. Place some bricks in the required height (top of the foundation) a couple of metres apart, tip on your concrete, working it in with a scoop to eliminate any air bubbles, and use a stout piece of wood to smooth it out between the bricks. Repeat this for the entire length of this base.
Bear in Mind that weather conditions can impact your well-laid plans. If you’re not going to put the concrete straightaway, It is advisable to cover the trench with sheeting and boards to maintain the Rain. Check also formwork concrete.
