Decking under the fence - what kinds are

What is fence formwork? In essence, this is a fairly strong frame, on the basis of which reinforced concrete structures are built.

Types of formwork suggest a choice of options:

• The formwork is vertical, thanks to which it is possible to construct steep surfaces;
• Wall formwork - used for the construction of vertical walls;
• Ceiling formwork involves the construction of horizontal surfaces;
• Architectural formwork - with its help more complex building elements are created.

Materials for fence formwork

The purpose of home formwork under the fence is somewhat different. Its task is to provide smooth edges of the concrete base and hold a large weight. Easy to install and disassemble - its distinctive qualities. Expensive methods of device leave the professionals, and at home for the manufacture of formwork, based on the height of the base relative to ground level, you can use sheet metal, ordinary boards, or coarse plywood.

It is very important not to rush, and the frequency of the reinforcing elements will allow to strengthen the fence formwork. It would be nice to pre-plan the boards, reinforcing the formwork, boards for all its bundles, metal sheets and plywood.

The desired size of the cross section of the beam to reinforce 50x50 mm boards for connecting 50x20 mm, but you can use other sizes. Prepare a holistic plywood and even, for the formwork will fit any plywood over 1.5 cm thick. Thinner can cause problems during the pouring of concrete.

Self-Formwork Fence

If you know how to make a formwork for the fence, you can make it yourself, thereby significantly saving the construction budget.

When the preparatory stage is completed, determine the dimensions of the concrete base. For example, its parameters can be 30 cm above the ground and 20 cm wall thickness, the depth depends on your desire.

The next step is to define the boundaries of the fence. It can be done with a rope or shovel. Now you can begin the installation of formwork. At first we fix the bars, deepening them by 50 cm at least into the ground and raising them 40 cm above the level. The bars are located on one side at a distance of 120 cm from each other. The second row is driven in opposite so that the bars are between the two already installed. Between two bars located opposite, a distance of 60 cm.

If there are minor distortions, it's not scary. After all, the main thing is that the design was reliable and durable.

Now is the time to apply plywood. Cut into strips up to 40 cm wide. Length may be different. But long strips are very convenient to use. We fix the plywood using a screwdriver and screws, avoiding the gap between the sheet and the ground. It is not necessary to tighten fasteners all the way. The alignment will occur after the concrete mass has been poured.

It is clear that the fastening of plywood is made inside the trench, and the bars will remain behind the sheet. Due to this, the edges will be smooth. Thus, we make external and internal formwork.

Now we make a bunch of bars. To do this, the board of 50x20 mm with the wide side is lowered down onto 2 opposite bars, fastened with self-tapping screws under a gradient of 45 degrees. This will provide an opportunity to get a concrete base with smooth edges.

After the installation is completed, proceed to pouring the foundation.
