SHAHABAD

The idea of ‘local’ is important in ecological architecture; hence any attempt to promote an outstation material can raise eyebrows.

However, certain attitudes like aesthetics, aspiration or cost reduction can justify outstation materials, if done judiciously.

This argument can support the idea of getting marbles from Rajasthan or equally good stones from Andhra Pradesh.

What do we get to see if we walk into an old restaurant? Possibly, a chess board pattern of grey and black tiles on the floor, while the restaurant kitchen could be finished with only the grey stone.

Many public buildings built in the near past also exhibit this floor pattern. They are made of Shahabad stone, grey in colour and Cuddapah stone, black in color

Kota stone is a naturally available limestone with an elite blend of shades. It is usually available in the Kota district of Rajasthan state of India . Kota stone is well known for its attractive colors. However, the brown color is the popular. Other colors are - Black, Pink, Grey, and Beige. Physical properties like hardness, non- porous and homogeneity make it extraordinary from other stones

Kota stone is used in two finishes i.e. rough dress and polished finish. It is an excellent building stone for Pathways, Corridors, Driveways, Commercial buildings. It is also used in chemical industries due to its resistant properties.

Marble stone flooring consists of 20 mm to 25 mm thick marble slabs laid over 20 mm thick base of cement coarse sand mortar of 1:3 and jointed with white cement slurry mixed with pigment to match the shade of stone. The marble stones/slabs used in flooring or dado are cut according to the size and shapes given in drawing or to suit site dimension of the room and desired pattern. All angles and edges of marble slabs are true and square and are free from chipping. The surface is true and plain.

Chequered tiles are the ideal solution for external flooring in heavy traffic areas - offering anti-slip flooring that gives a better grip and does not wear out easily. Its a heavy duty combination for heavy duty applications.

Chequered tiles have exceptional strength to withstand the toughest daily grind and the heaviest wear and tear. Manufactured under hydraulic pressure, they are more wear-resistant than ordinary chequered tiles. An ideal choice for parking lots, driveways, pathways, swimming pool decks, building compounds, petrol pumps, warehouses and heavy traffic areas

Glazed tile is a type of ceramic tile to which a glaze has been applied. After the glaze is painted or sprayed on, the tile is filed at high temperatures, causing a chemical reaction which makes the glaze vitrify, essentially turning into glass. The resulting tile is resistant to water and stains because of the glaze, and it has an attractive look, as a wide variety of colors and designs can be created with glaze, with finishes ranging from extremely glossy to matte. Any store which stocks tile flooring will carry glazed tile, typically in a range of configurations for people to choose from.

Block paving also known as brick paving is a commonly used decorative method of creating a hard standing. The main benefit over other materials to create a hard surface are that the individual bricks that go together to make up the block paved surface are able to be lifted up and then replaced. This allows for remedial work to be carried out under the surface of the paving without any visible notice to the surface once the paving bricks have been replaced. This is kind of brick paving is said to be flexible paving. Typical areas of use would be for driveways, pavement, patios, town centres, precincts and more comamonlyin road surfacing. There are two common makes of block paving brick, concrete and clay. Although other composite materials do exist to make up an individual brick. Each with its own way of preparation that go to make up the construction of a paving brick. The biggest difference is the way they set hard ready for use. A clay block paving brick has to be fired in a kiln to bake the brick hard and a concrete block paving brick has to be allowed set. See concrete. The concrete paving bricks are a porous form of brick formed by mixing small stone hardcore, dyes, depending on the finished colour required, cement and sand in various amounts.

Terrazzo is a highly versatile material that has been used as a flooring product since Roman times but can be moulded into almost any shape. Terrazzo tiles and Terrazzo flooring is used throughout the world in locations such as train stations, airports, shopping malls and supermarkets and enjoys an enviable reputation due to its combination of durability, ease of maintenance, beauty and performance.

Terrazzo was developed in Friuli in the North East of Italy, where the local residents used the pebbles from a nearby river to pave areas surrounding their homes. Although this produced an uneven surface a method was eventually realised to smooth it down and it is now the number one choice for areas that are to be well trafficked.

The material is a composite of natural marble chippings set in a matrix of cement with a colour pigment added to it. The range of aggregates in size and colour is vast and they can be set into practically any colourcement to create an endless amount of finishes. Once laid, the terrazzo is ground down and polished to expose the aggregate

FLOOR FINISH TYPES

There are many types of floor finishes currently available in the market place. At

Profile Timber Floors we take the time to recommend the best product to suit your

needs and your lifestyle.

Oil-Based/Solvent Based Finishes

Finishes containing oil-based alkyds with the addition of urethanes provide a finish

with reasonably good abrasion resistance. A strong odor is prevalent during

application but dispels as the floor dries. These finishes provide a subdued, satin to

semi-gloss appearance. This product darkens with time and requires greater

Maintenance especially in high traffic areas.

Polyurethane Finishes

Solvent-based polyurethanes (one pack and two pack) provide a harder finish. This

greatly reduces the level of routine maintenance. They provide some of the hardest

finishes available today with gloss levels from Matt through to a very High Gloss. A

strong odor is prevalent during application but dispels as the finish dries. Du e to

their high strength and generally limited flexibility, edge bonding of boards can occur.

Water Based Finishes

Some water based polyurethane/acrylic mixes of moderate durability are available

but straight one and two pack water based polyurethanes with very good wear

resistance are gaining in popularity. Matt through to Gloss finishes are available.

•Seepage or leakage is percolation of water through the voids or spaces of the material.

•Seepage may occur through defective water pipes , sanitary fitments or drainage pipes , etc.

To overcome this problem of seepage , waterproofing of structure is necessary.

Waterproofing helps to maintain the beauty and increase the life of the structure.

The concrete surface shall be cleaned thoroughly of all laitance, loose particles ,dust ,grease ,etc.

Apply bonding agent mixed with water in the ratio of 1:1 to sides of wall and bottom surface.

Finish the surface smoothly with the ratio of cement :sand : WPL =1:4:200ml.

After this the pipes are arranged. The seepage pipe is also placed in the hole.(slope is provided at one corner)

Applying the bonding agent + water in the ratio of 1:1 at the hole.

Fill the hole with cement :sand : WPL + 6mm gravel (1:4:200ml)

Place a wire mesh at the entrance of seepage pipe so as to allow leaked water freely.

For double coating, fill the toilet with bricks or coal . Place cement : sand: wpl(1:4:200,l) paste in between bricks.

Finish the surface smoothly. Finally tiles are layed in the bathrooms applying white cement in between the tiles

What is rising damp

Rising damp is the upward movement of ground water through permeable masonry walls. The water rises through the pores in the masonry wall via a process called capillarity. Capillarity is an electro-chemical process whereby water molecules are attracted to mineral surfaces, enabling water to move vertically through pores of a certain size despite the counteractive force of gravity.

What is a damp proof course

There are two main types of damp proof course (DPC). The first is an impervious barrier, usually laid along a bed joint during the construction of a building. The second is a remedial chemical DPC, which can be introduced by trade specialists, competent builders or DIY enthusiasts. The damp proofing chemical is normally applied along the base of walls that are suffering from the effects of rising damp. Contrary to common belief a chemical DPC does not form an impervious physical barrier. Chemical damp-proofing is an effective method of lining the pores along a stretch of masonry wall with a silicone resin water repellent. For the purists, a pore-lining silicone rising damp treatment works by neutralising the charge attraction of the masonry pores to the water molecules.

Termites are a group of eusocial insects that, until recently, were classified at the taxonomic rank of order Isoptera (see taxonomy below), but are now accepted as the infraorder Isoptera, of the cockroach order Blattodea .[1][2] While termites are commonly known, especially in Australia , as "white ants," they are not closely related to the ants.

Like ants , and some bees and wasps — all of which are placed in the separate order Hymenoptera — termites divide labor among castes, produce overlapping generations and take care of young collectively. Termites mostly feed on dead plant material, generally in the form of wood, leaf litter , soil, or animal dung, and about 10% of the estimated 4,000 species (about 3,106 taxonomically known) are economically significant as pests that can cause serious structural damage to buildings, crops or plantation forests. Termites are major detritivores , particularly in the subtropical and tropical regions, and their recycling of wood and other plant matter is of considerable ecological importance.
