Waterproofing and Damp Proofing Materials:
Waterproofing of a surface is that the treatment of the surface to stop the passage of water like fresh water or water from one aspect of a structure to the opposite below traditional pressure.
Methods of water proofing >
1) Waterproofing with hydrocarbon sheets.
2) Water proofing by suspension coats on the roof and covering it with tiles.
3) Waterproofing with elastomeric paints.
4) Waterproofing with epoxy formulations.
Most of the waterproofing materials area unit on the market in liquid and powder kind. Integral liquid waterproofing compounds area unit on the market in plastic bottles of various sizes whereas integral powder waterproofing compounds area unit on the market in waterproofing boxes or synthetic resin baggage.
Properties of waterproofing materials :
1) It ought to be proof
2) It ought to be sturdy
3) It ought to be able to resist hundreds to that it’ll be subjected.
4) It ought to be in position to accommodate some structural movement while not fracture.
Dampness >
Dampness during a building is that the presence of wetness in varied elements of building like floor, wall, roof etc. Causes moistness during a structure:
1) Poor emptying at the lot.
2) Imperfect orientation: Walls obtaining less daylight and serious showers might stay damp.
3) Imperfect roof slope: it’s particularly within the case of flat roofs.
4) Defective construction: Imperfect wall joints, joints in roofs, defective strangulation etc.
Three effects of dampness:
1) Patches develop and destroy the looks of the building.
2) colour wash, white wash and paintings area unit broken.
3) Plaster crumbles.
4) Bricks and stone disintegrate endangering the building.
5) Steel within the slabs and beam begin corroding. It reduced the lifetime of structure.
6) Dry decomposition of wood takes place. Damp proofing is that the treatment of a surface to prevent the increase of water by surface tension.
Damp proofing is that the treatment of a surface to prevent the increase of water by surface tension.
Properties of ideal damp proofing material :
1) It ought to be proof.
2) It ought to be versatile.
3) It ought to be sturdy.
4) It ought to be simple to hold out leak proofing joints.
5) It ought to resist the load safely.
Some ordinarily materials area unit used for damp proofing :
1) versatile materials like hot hydrocarbon, hydrocarbon felts, plastic sheet, metal sheet of lead, copper etc.
2) Semi-rigid materials like mastic asphalt.
3) Rigid materials like proof bricks, stones, slates, cement mortar or cement concrete painted with hydrocarbon.
4) Mortar with water proofing compounds.
5) Continuous plastic sheets below floor.
Methods of building damp proofing :
1) Use of damp proofing course (D.P.C.) Membrane damp proofing.
2) Integral damp proofing.
3) Surface treatment.
4) wall construction.
5) Guniting.
6) Pressure grouting.
