Dampness in building or house may cause most of the damage to the components of the building or house. Dampness often leads to the growth of molds, mites and bacteria that creates an unhealthy environment and causes health problems. Dampness gradually impairs the affected part of the building, so this problem should be attended as soon as possible. There are many methods or treatment used to protect the house from dampness. Damp proofing with the help of chemicals are as under.
Damp Proofing-Chemical Treatment
1) Instant leak plugging Compounds
|S.No||Name of compounds||Name of Manufacturer||Nature of Compound||Uses|
|1||PIDIPATCH 103||M/s Pidlite||A quick setting cement that solidfies immediately on contact with water.||Ideal for instantaneous sealing of leaks, surface dampness, water penetration and seepage points.|
|2||Rendroc Plug||M/s Forsoc||Rapid setting mortar prepacked dry powder only water addition is required.||Instant repair mortar for running water leak.|
|3||Techaqua||M/s Choksey||Two component epoxy compound||Underwater repairs on concrete sturctures can be used for stopping active leaks in basement pits, underground tunnels, bridges, dams etc.|
2) Some Flexible Sealants (To seal gaps, joints, cracks etc. which exibit movement)
|S.No||Name of Coating||Name of Manufacturer||Nature of Compound||Uses|
|1||Crackseal||M/s Chemisol Agencies||One component white sealing compound on an acrylic base which hardens to plastic elastic putty with high elasticity. surface to be wet before applying.||For filling cracksjoints and gaps of windows, doors, concrete slab, masonary surface glass, tiles, pipes, A.C, G.I sheet, wash basin. Highly elastic end ductile in wide temrature variation. Does not shrink, crack or crumble. Paint can be applied over it.|
|2.||Techmast||M/s Choksey Chemicals|| One component butyl rubber based sealalnt. Should be applied on absolutely dry surface.
Movement accomodation 15% of total joint width.
|Sealing of cracks in buildings, roof, terraces, walls and concrete water tank. Sealing of joints in pipes, aluminum ducting to prevent leakage and small joints between window and door frames and surrounding bricks, concrete, stone work etc.|
|3.||Techseal ( Polysulphide based sealants)||M/s Choksey Chemicals||Two components polysulphide based sealants i.e one component is liquid and second is accelerator containing a chemical curing agent. After mixing it forms a strong rubber like sustance which is highly elastic, flexible and has out standing resistance to weathering chemicals and excellent adhesion to all building materials.||Used where movement of joint is more and joint is subjected to high wear and tear and more resistance to weathering chemicals is required i.e expansion joints in water retaining structures, dams, canals etc. Joints in basement retaining wall, joints in bridges, roads, car parks, joints in industrial/ heavy duty floor.|
|4.||Chemistic rubberized joint filler||M/s Chemisol Agencies||Single component black color sealent||For filling cracksjoints and gaps of windows, doors, concrete slab, masonary surface glass, tiles, pipes, A.C, G.I sheet, wash basin. Highly elastic end ductile in wide temrature variation. Does not shrink, crack or crumble. Paint can be applied over it.|
|5.||Pidiseal-PS||M/s Pidlite||Two part polysulphide sealant available in two variety-gungrade and pouring grade.||Sealing movement joints in all types of construction ( especially use for expansion joints).|
|6.||Rhodorsil 3B RTV Silicon Sealant||M/s Pidlite||One component silicone sealant||Sealing joints, gaps, cracks, (movement accomodation ± 35% of joint width).|
3) Rigid Sealants ( To fill holes/ gaps/ joints / cracks which do not exhibit movements)
|S.No||Name of Sealant||Name of Manufacturer||Nature of Compound||Uses|
|1.||Polyseal||M/s Greenboro||Two Component apoxy putty||For filling or sealing cracks, gaps, holes, joints in wood, concrete, metals and ceramic( where there is no movement of joints. Should not be used for very hot areas.)|
|2.||M-seal||M/s. MECP (Mahindra Engineering and Chemical Product Ltd.)||Two Componenets ( Resin and Hardner) apoxy putty||For filling or sealing cracks, gaps, holes, joints in wood, concrete, metals and ceramic( where there is no movement of joints. Should not be used for very hot areas.)|
|3.||Metal putty or NC putty||M/s Balsons Paint||Single component, hardens in 2-3 hours.||For filling holes in steelwork, finishing of weld etc.|
|4.||Feviseal||M/s Pidilite||2 component apoxy putty. Sets hard within 20 minutes. Final curing strength achieved in 4 Hrs.||For filling or sealing cracks, gaps, holes, joints in wood, concrete, metals and ceramic( where there is no movement of joints. Should not be used for very hot areas.)|
|5.||Glazing Putty||Local Makes||Made by mixing one part of white lead with three parts of whiting and then adding boiled linseed oil.||Normally used for securing glass panes in rash. But can also be used for filling gaps, holes, joints cracks etc. inside the building which are stationary in nature.|
4) Coatings which can be done over damp sealings and damp walls to prevent seepage.
|S.No.||Name of Coating||Name of Manufacturer||Nature of Compound||Uses|
|1||Techoxy||M/s Chocksey Chemicals||Water thinable apoxy( can be applied on damp surfaces also. No primer needed) can be over coated with enamel paint with excellent adhesion.||Water proofing of tanks inside, interior walls, interior ceiling coverage.|
|2||Chemistic Damp Proofer||M/s Chemisol Agencies||Single component can be applied on damp surfaces. White color. Stainer can be mixed to give required color. Primer not needed. Painting if requirded can be done directly over it.||Damp proofing of toilets, interior walls, basements, underground tanks. It is especially useful at interior loctaions where seepage is already occuring.|
