Fig.3: Concrete mix preparation and placement for plinth beam construction Minimum Dimension of a Plinth Beam

Our concrete gravel boards are available in two different heights. These are 6 inches and 12 inches (1ft). If you would like your fence panel raised higher from the ground, we would recommend the 12 inch (1ft) concrete gravel boards. Once your first concrete fence post has been erected and is set in place, ensure that the area you are fencing is level and measure the distance of your gravel board and dig a hole where you need to install your second fence post. Place your concrete gravel board in the grove of the first fence post. All of these options are easy to install and provide a significant level of protection to your fencing project.Reinforcement bars should be protected by 25mm concrete cover. As far as stirrups are concerned, stirrup diameter should be at least 6mm and a spacing of 15cm should be sufficient. Formwork used for plinth beam construction should be properly installed and adequately secured prior to concrete placement as shown in Figure-4. The concrete needs to be compacted sufficiently to prevent steel bars from aggressive elements. A minimum depth of plinth beam is 20cm whereas its width should match the width of final course of the foundation. Strength of plinth beam concrete shall not be smaller than 20MPa. If concrete is mixed manually, then an extra of 20% cement need to be added to the mixture. Figure 3 show plinth beam concrete preparation placement. If you are installing a traditional close board or feather-edge fence we can supply six inch high concrete gravel boards to suit. We offer this variant in two different lengths (2.4m and 3m) dependant on post spacing. This item can be bolted to recessed concrete fence posts by way of a carriage bolt or can be screwed to timber posts. Concrete Gravel Board Installation

Concrete gravel boards are a long term cost effect method of improving the longevity of your fence panels. Easy to install, concrete gravel boards raise your fence panels off the ground, helping to reduce the risk of moisture damage such as rot and decay that would otherwise be caused by damp or wet ground. Concrete lintels provide durable support for a variety of different structures and architectural elements, giving you a reliable way to distribute weight and hold doors and windows in position. Jewson prestressed and precast concrete lintels can be used to disperse pressure over a larger area, reducing the risk of structural instability. Oakdale Fencing supply a variety of different concrete gravel boards. Depending on how high you wish to raise your fence panel, our concrete gravel boards come in 6 inch and 12 inch options. Once in place install your fence panel on top of the concrete gravel board and in the grove of the fence post. Erect your second fence post ensuring the fence panel and gravel board fit in the posts slot. Repeat until you have completed your fencing project.

The Swift Plinth concrete plinth foundation base is an amazing foundation solution offering a cost saving and easy alternative to concrete foundations.

It is recommended to provide two bars with minimum diameter of 12mm at the bottom of the beam. Similarly, two bars with minimum diameter of 10mm shall be provided at the top of the plinth beam.

The standard width of a concrete gravel board is 6ft. This matches the width of a standard fence panel (also 6ft wide).
