Guidelines to Use Blocks

a. General

1. Details of sizes of blocks for walling, partitions and cladding are available in our price list
2. blocks should be stacked in dry, well ventilated areas on a level ground. Block should be placed on edges (in the direction of 240 mm height) not on flat (in the direction of the thickness). Different stacks should be maintained for different sizes of blocks
3. siporex blocks should not be used below ground level or in plinth
4. damp-proof course should be provided before starting superstructure masonry
5. generally, load bearing structures using 20 cm (8”) siporex blocks can be constructed up to two storeys, I. E. G 1 buildings. Three and more storeys will be in “frames” structures. However, it is necessary to design load bearing / partition wall as per relevant is specifications
6. siporex blocks and slabs are highly suitable for extension or addition of floors to existing old or new buildings because of their lightweight characteristics

b. Masonry with Siporex blocks

1. Cement mortar 1 : 6 using portl and cement should be used
2. blocks shall be placed in the direction of 240 mm height in the masonry
3. It is not necessary to soak the siporex blocks before their use in masonry. Their surface should be wetted sparingly and afterwards water should be sprinkled for curing of masonry joints
4. for breaking of joints in the masonry, specifications for brick masonry work shall be adopted for guidance
5. at door and window openings, 2 nos. 6 mm dia bars should be provided at the top of the openings to avoid cracks on plaster. The bars should be provided in the course immediately above the lintel and bar should be extended 0. 6 m on both sides

Guidelines to Use Slabs

Guidelines for clients using Siporex slabs

Loading, packing and transportation
1. After proper loading, the stacks of slabs are to be tied properly by using soft manila rope. The whole assembly is to be rigidly tied to the body of the truck to avoid any damage to the slab. For long distance transportation by road, proper packing should be done to avoid damages in transit.
2. the vehicle should move steadily along the road. Sudden stoppage & speeding up should be avoided.
3. During transit, height of stack on the truck should not exceed 1. 50 m. It is essential to cover the slabs by tarpaulin or any suitable cover.
4. the slabs should be stacked horizontally.
5. slabs should not be used for covering septic tanks / water tanks.

Unloading and stacking

1. the slabs should be unloaded preferably with a lifting tool (grab) or manually with proper care.
2. in addition to this, to prevent direct damage to the slabs while unloading, provide two wooden sleepers on which slabs should be gradually unloaded.
3. the stacking of the slabs should be done as shown in fig. 1.
4. care should be taken to see that the material is transported to the site when it is actually needed for work. Unnecessary stacking of slabs at site should be avoided.
5. the slabs should be placed on plain ground on two timber scantilings 3" x 3" size put crosswise to the slabs at about 114 the span from the ends.
6. the stack of the slabs should not be more than 1. 50m in height.
7. the ground selected should be levelled so as to avoid any water logging.
8. the slabs should be placed in such a way that arrow mark on the end of each slab points upward.
9. if the slabs are to remain during monsoon at work site, proper temporary shed should be provided to allow air to pass through. Alternatively, the slabs should be properly stored in the building where construction is complete and room is available or stacks should be covered with tarpaulin or polythene paper.
10. at the time of removing the slabs, no sharp pointed instrument such as crow bar or hooks should be used to lift the slab or to arrange them in position.
11. the slabs of different superimposed loads shall be kept in different stacks.
