Types and construction process of compound wall
The purpose of a compound wall is to contribute elegant look, privacy and security to any building. It checks movements of unessential objects in the building. It is erected to detach any building from other building and arrange proper segmentation to your property.
Types Of Compound Walls: Based on the appearance & construction material applied, various types of compound walls are found in building.
In this construction article detail information is given on masonry compound wall and precast compound wall.
Masonry Compound Wall: Red clay bricks / Fly ash bricks, steel and cement mortar are considered as the major components for masonry compound walls construction. The compound wall is built up from 2 ft. below ground level to provide perfect anchorage to the wall.
Toward Individual House Construction, the height of the masonry compound wall is normally kept among 5-6 feet and the thickness is normally150mm.
Once excavation work is completed, a PCC of 100 mm thick and 600 mm wide is provided to develop an even surface on which the compound wall can be placed.
A rubble masonry having 450 mm width and up to 2 feet height is arranged underneath the brick wall to disperse the load of the structure constructed above.
Over rubble masonry, a RCC Coping of 4" thick is formed for making the surface smooth as well as transmitting the loads of the compound wall to the substructure underneath.
Over RCC coping, masonry compound wall is built up with 6?Red clay bricks or 4? Red clay bricks / fly ash bricks. Intermittent brick columns with dimension 300mm X 230mm are erected at a distance of 7 ft to 10 ft center to center and at the corners of the plot.
Once the curing of this masonry wall is completed, cement plaster is employed on both the sides of compound wall and paint is used.
The cost of a standard masonry compound wall that is normally applied in residential buildings averages to Rs. 1200/Rft along with a 8 Feet wide MS Gate on the front size. The cost may fluctuate +/-10 % based on the accessibility of local materials like bricks, rubble etc.
Bonus Tip: To enhance the elegant look of the wall, the grooves can be included with the plaster.
Precast Compound Wall: Currently, precast compound wall is mostly found in different areas since they can be set up simply and finished within very short span. But the strength and stability of the compound are not up to the standard.
To create perfect precast compound walls, the consideration should be given on developing proper foundation to the structure and the walls.
As the precast compound walls are factory made and are transmitted to site, the overall cost is considerably less with regard to masonry compound wall. Based on the design and necessary customization, the cost fluctuates significantly.
The cost of a precast compound wall normally commences from Rs. 60 per sqft (i.e., roughly Rs 400 per Rft). This cost is exclusive of the cost of foundation, painting, gate, any other finishing etc. Therefore, while measuring the cost of precast compound wall, all these should be contained in overall costing.
