You will need
- - cement;
- - sand;
- - gravel;
- construction drill or shovel;
- - wire;
- - pillars;
- - planks for formwork;
- - the plumb.
To install brick pillars, dig a trench for the Foundation laying. The depth of the trench do the same, as the installation of greenhouses, 50-70 cm Install formwork, add a bottom 20-25 cm sand and crushed stone, all tightly tamp it and pour the Foundation. The ratio of concrete shall be as when pouring of all foundations and consist of 1 part cement, 3 parts sand and 3 parts gravel.
Give the Foundation time to gain strength, put two rows of plinth of red brick. Mark on the pillars. First, mark the edges, then measure the entire length, divide it into equal parts and make masonry pillars. Masonry pillars entrust a professional Mason because the occupation is very difficult. Each post must measure in the exact line as in the construction of the corners of the house, otherwise they will have different angles and can go in different directions. In General, having no experience, put the pillars is impossible, though it seems a simple matter.
To install iron, wood, asbestos-cement columns, use a construction drill. This will allow the smallest way to loosen the soil around the poles, and for their fastening will take much less gravel and sand. But you can dig holes for poles and shovel, if construction drill anywhere to get failed.
Mark the distance, pull the wire on the installed pegs. Select columns, check the installation plumb, fill the resulting hole with rubble and sand, again check the posts plumb, tamp everything thoroughly.
To secure the posts, you can use grout the same as for the pouring of the Foundation. To do this, set the columns evenly, fill the holes with mortar, tamp the mortar with a stick to release the bubbles which make the mortar less durable.
If the soil in your area is sandy peat, in General, are fragile, then before you set the posts, bottom holes for them to add gravel and tamp thoroughly. Only on a layer of gravel to set the posts.
For greater strength can around the installed posts to do the formwork and pour cement mortar. Get a thin strip Foundation where the columns will be securely fastened.
Advice 2: How to dig posts for a fence
On what columns you select for your fence – wood, metal, concrete, asbestos – will largely determine its longevity. But it is equally important to properly install poles, mounting method should be chosen depending on the depth of groundwater, composition of the earth, the value of the fence.
You will need
- sledgehammer or grandma for hammering;
- - drill or drilling rig;
- - concrete solution;
- - sand;
- - fine gravel.
On light or sandy soil to install small posts, use the normal hammer. Place the pole upright and, holding his hammer, until he is sufficiently developed.
To facilitate the work, use the tailstock, is made of larger diameter pipe and welded on the one hand a plug, here, take a weight of lead or metal. The side weld of the handle. Put the pipe on the pole, vertically mounted, lift by the handles and drop down.
To set large poles, or purchase a special drill book the drill rig. Drill with it, well a little below the depth of soil freezing, pour a bed of sand. Next, install the inside the post and fill the remaining space with concrete or cover with soil and tamp.
After pouring the concrete mix into the hole a bit and raise the pole. In this case the bottom part is also closed by a layer of concrete that will protect the wood from rotting and metal from rusting.
In sandy soil you can do without a fill and compaction, simply drill the hole just under the diameter column. In this case, be careful that the hole was vertical and located strictly in line.
Heaving clay soils with a high level of occurrence water use the following method. Drill out the hole obviously wider than the column diameter and deeper groundwater. Complete the back of the hole with fine gravel and sand so that there is sufficient depth for immersion of the third pillar.
Tamp the drainage and install a pole. The space around the column fill with fine gravel, sand, and tamp thoroughly. With this method of installation, the groundwater will be free to go down and can't push the pole out of the ground, he will stand firmly and not mowing over time.
Advice 3: How to dig posts
To set posts for a fence, it is important to consider the condition of the soil, the material of the poles themselves and to prepare everything necessary for the job. Should not only to set the props, but also properly to fix, so after the first winter didn't have to redo everything and spend time on one and the same work two times.
You will need
- the a-pillars
- -thin wire, nylon thread or cord
- -antiseptic, water-resistant primer, mastic (if the poles are wooden)
- sand, cement (for added reinforcement)
- -shovel or auger
You can put any posts: wood with iron or asbestos cement. Before you begin to dig or to drill holes for mounting, make marks at posts. Hammer bars are slightly wider than will stand themselves pillars and pull a thin wire, nylon thread or cord. Thus, you need to mark the bottom, middle and top.
Then mark the distance between the posts. It must be the same and match the length of the material you are going to strengthen the quality of the fence.
The pits under posts you can dig with a shovel or to drill. If the soil is weak and prone to heaving during frosts, the method of hole punching is completely different from the hole with a shovel. You can dig or drill, but the pillars still need further strengthened. This will require chippings. The depth of pits for the installation, you need to do the same and not less than 50-60 cm In the loose soil you need to dig even deeper given the fact that the bottom of each pit will have to pour sand on him to tamp the gravel and only for the cushion to establish themselves poles. And it will have to do together. One person will hold the post, the second – fill the pit with gravel and to tamp it. It is a versatile method of installation and suitable for pillars of any material.
Before installing pillars of wood, you should treat it with a layer of antiseptic. After drying, a layer of a waterproof primer and top apply mastic of tar, which you can buy at any hardware store. This treatment will extend the life of wooden posts many times, and they shall stand no less than iron or asbestos cement.
For greater strength, and most importantly, self-confidence, you can set the bottom two sides of the row of pillars, the timbering of 20-30 cm and pour concrete. Get the Foundation for the fence, which will further provide protection of installed material from contact with the soil, and therefore, prolong its service life several times.
