Box type waterproofing

Box Type Waterproofing

This type of water proofing system is used only for basement waterproofing or waterproofing structures below the ground level from outside to prevent leakages of subsoil water into the basement. This method is quite popular with some designers and effective even now.

In this method stone slabs (Kota or Shahabad Stones) are first laid in the excavated pit over blinding concrete in a staggered joint fashion to avoid the continuity of the mortar joints. The joints are effectively filled with rich mortar admixed with integral waterproofing compound and cured. Over this the raft is laid and shear/brick walls constructed. The slabs are erected around the walls in a similar fashion leaving a gap of one to two inches between the external surface of the wall and the inner face of the stone surface. The joints again effectively sealed with rich admixed mortar and the same mortar is filled in the gap between the wall and the stones. This stonework is continued up to ground level. In this system the raft and the sidewalls are protected from direct exposure to sub soil water.

This system works on two principles of common sense. First the area exposed to subsoil water is only the area of the joint where as the whole stone is impervious to water, hence only a fraction of area, that is, that of the joint is exposed to subsoil water, when the joint itself is filled with rich and quality mortar. Secondly, the path of water to reach the raft or the sidewall is elongated. This elongated path is through quality mortar. This system seeks to delay the occurrence of leakages in the basements. A lot of building structures are waterproofed by this system.

Floor Installation

• Preparation of surface by cleaning, leveling etc.
• 20 mm thick cement-sand-mortar mixed with water proofing powder, 4% by weight of cement shall be laid on PCC and 20 mm graded aggregate free from impurities shall be spread on the floor. It shall be cured for 3 days.
• Provide insert sockets and pipes to release the sub soil water pressure.
• Then 18-20 mm thick stones ( Kota or Shahbad) of approximate 600 x 600 mm in size shall be laid flat and joined with cement-sand-mortar. This shall project 300 mm all around RCC raft. The stones shall be hard tough and free from cracks.
• Then the surface shall be screeded with cement-sand mortar and finished smooth.
• RCC raft, walls or masonry shall be constructed as designed.
• The sockets / pipes are grouted with pressure.
• Columns or any support etc. coming out of raft shall be sealed with poly-sulphide sealant at PCC level and at top of raft

Seasoning natural stone, Bedding stones, Cast stone: used in construction of buildings.

Seasoning natural stone, Bedding stones, Cast stone: used in construction of buildings.

Seasoning natural stone.

Some natural stones are comparatively soft and moist when first quarried but gradually harden. Building stones should be seasoned (allowed to harden) for periods of up to a few years, depending on the size of the stones. Once stone has been seasoned it does not revert to its original soft moist state on exposure to rain, but on the contrary hardens with age. 

Bedding stones.
Natural stones that are stratified, limestone and sandstone, must be used in walling so that they lie on their natural bed to support compressive stress. The bed of a stone is its face parallel to the strata (layer) of the stones in the quarry and the stress that the stone suffers in use should be at right angles to the strata or bed which otherwise might act as a plane of weakness and give way under compressive stress. The stones in an arch are laid with the bed or strata radiating roughly from the centre of the arch so that the bed is at right angles to the compressive stress acting around the curve of the arch. 

Cast stone.
Cast stone is one of the terms used to describe concrete cast in moulds to resemble blocks of natural stone. When the material first came into use some 50 years ago it was called artificial stone. To avoid the use of the pejorative term artificial, the manufacturers now prefer the description reconstructed stone.

STONES -QUALITY DETERMINANTS

STONES -QUALITY DETERMINANTS

.

Quality of a stone determines the Quality of stonework. Other factors include quarrying method, seasoning, dressing technique, and masonry or cladding style. The important properties of building stones are: durability, hardness, toughness, porosity and strength under various types of stresses. The structural properties are, mainly governed by: the class of stone (sedimentary, calcareous, igneous, etc.), mode of occurrence (surface, shallow depth, very deep mines), type and condition of the rocks (horizontal or inclined mass). The structural properties do get substantially altered by the subsequent handling of stones, such as: exposure, action of environmental factors (moisture, salt, contaminants, temperature) mechanical pressure, vibration, etc.

Sand Stone block open exposure

Most of the stone materials are extracted from a depth. Such materials have remained buried under heavy over loads, devoid of oxygen and other gases, and free of moisture, or with entrapped moisture or flooded in subsoil water, and without light or radiation exposure, possibly since their age of formation. On extraction the stone material is brought to a completely different environment. Mineral lattices begin to alter due to lessening of pressure and dehydration. Entrapped gases escape and the space begins to get filled in with moisture and atmospheric gases. In sedimentary deposits the excess moisture begins to escape, allowing minerals react, causing expansion or contraction stresses in the mass. Rain water which is slightly an acidic one causes calcium carbonate to change into bicarbonate. In industrial areas sulphur and carbon dioxide enhance the acid action on the freshly quarried stone. Chlorides on sea front and in industrial areas can get converted into weak hydrochloric acid and dissolve the carbonate rocks. Nitric acid produced from oxide or Nitrogen also corrodes stone faces. All corrosive mediums depend on supply of water or moisture, so care of fresh-cut stone is essentially a moisture management exercise.

Bio-weathering

Freshly quarried and exposed stones are affected by: 1Temperature variations cause differential expansion and contraction of the mass causing cracking or splitting. 2 Wetting and drying cyclesof rain or dew, and frost may disintegrate the stone. Other moisture associated, problems are of living organisms that flourish in wet grounds. Stones stored here are affected by algae, lichens destroy lime stones, and worms destroy all stones except granite. Vegetation growth is a problem in tropics and heavy rainfall areas. 3 Polluted atmosphere around cutting centres (industrial areas, dumping sites and sea shores) affects the surface quality. 4 Stones need to be stored in same position as they were in natural state. Layered stones such as sedimentary rocks must never be stored in vertical position before sufficient seasoning.

Roughened surface of Granite due to water and Sun

Seasoning is both drying and wetting cycles on one hand, and airing of stone, on the other hand. There is an increase in strength due to the re-deposition of percolated minerals, surface carbonation, transmission and deposition of minerals on the surface of a stone, by both the evaporating moisture, and addition of water. Dehydration, during seasoning, is more or less an irreversible process, Seasoningapplies mainly to soft limestone; hard limestones seem to be less affected by it.

Stones have natural moisture, known as quarry sap. This quarry sap renders the stone blocks comparatively soft and makes them easily workable. Immediately after quarrying, a stone is soft and it is easy to work with it so sized and primarily dressed, but polishing requires a fully seasoned and hardened stone.

Tandur (sedimentary) stone stored upright after weathering

Weathering denotes both desirable and undesirable changes. It is concurrent process of seasoning. It enhances certain qualities, like colour, texture, strength, etc. and reveals micro fissures deep pores on the surface. Weathering is very effective for Lime-based stones, which absorb atmospheric Carbon-dioxide to produce hardened mass.

Salt weathering

Porosity has no direct relation to the weathering resistance of stone materials, such as limestone. It is the shape, size, depth, and nature of pores, that plays an important role in weathering. The action of carbonic acid, increases with greater micro-porosity, capillariesprolong the dissolving action because the water is retained longer in small cavities. Sandstones containing colloidal minerals as a cementing medium has the most pronounced expansion due to porosity.

Slate stone in Polluted Environment

Efflorescence (wall white, stack white or wall cancer), is the appearance of crystallized salts on the stone’s surface. ‘The crystallization of the salts, and their re-crystallization from a lower to a higher hydrate within the range of mineral stability, may develop stresses of high magnitude with quite an appreciable qualitative change.’

exposed stone by tandur stone

Creating a powerful look by changing up the color or texture of a single wall is one of the most effective tools when it comes to decor. Painting a wall in a bold color is the most common method people use, but using tandur stone or tandur stone can have an even larger impact.

tandur stone and tandur stone tiles are available in sum colors and textures and are most commonly associated with redecorating or revamping a fireplace. But it’s time to think bigger for making one wall stand out and become the visual focal point of any space. Using this inspiration on a wall which separates a living room area from bedrooms or a home office can provide added, and natural, sound insulation. This can help for families who enjoy entertaining but want a way for their children or other family members to be able to relax.

Small spaces can especially benefit from this approach. Tiling a wall in a small bathroom or home office with natural stone helps to create a warm and cozy feeling without making the space feel crowded or claustrophobic. In a bathroom, accenting with stone on the wall behind the sink works as a way to enhance the space and provide a natural back splash.

While stone does imbue an area with a natural and environmental beauty, not all stone is created equal. Rough cut, rounded edges may give a space a truly country or outdoorsy feel, but marble, granite, slate and other smoother stone options can add the modern and elegant look you might be going for. Use granite or marble to line a shower and people won’t be thinking of the outdoors necessarily, they’ll be too busy being impressed by the smooth lines and ultra-modern feel stone can provide.Stone is one of the most surprising materials when it comes to home decoration. By simply focusing on color, texture and the type of cut, anyone can find an option that works for them and their space. Choosing natural stone or natural stone tiles for any indoor makeover opens a world of possibilities while creating a link between your home and the world around it.
