The various methods applied for the protection of dampness in buildings are following:
INSTALLATION OF A PHYSICAL DAMP COURSE
- Knapen Tubes
- Installation of a Physical Damp course
- Installation of a Chemical Damp Course.
- Chemical Impregation Under Gravity
- REPLASTERING: The most common method is to scale the affected damp plaster back to the brickwork and replaster the affected area with a waterproof plaster or cement mixture.This may stop minor damp problems reappearing but severe cases tend to reappear some time later above or beside the treated area.Replace the entire surface with waterproof plasterboard.Others use a technique of attaching battens to the affected walls and nailing on plasterboard providing a gap of 5mm to 10mm between the old surfaces and providing ventilation slots for top and bottom.All timbers should be decay-resistant and rust resistant.
- KNAPEN TUBES:Sloping holes are drilled in the affected area at skirting board level.Porcelain or similar tubes are inserted into the holes.Moisture in the wall drains into the tubes and evaporates (a sort of mini agricultural drain).
:This method has traditionally been regarded as the most effective (also the most costly) cure for rising dampness.It involves removing a line of bricks close to floor level.Then a plastic sheet is inserted along the line and the old mortar is replaced with waterproof mortar.Each re-mortared section needs to set for around 48 hours before it can take the weight of the wall again.
INSTALLATION OF A CHEMICAL DAMP COURSE:Pressure injection of a higher alkyl siloxane solution is the most widely used method.Holes are drilled into the bricks at regular intervals.The solution alkyl siloxane is pumped into the holes and permeates the bricks and surrounding mortar creating a broad band of water repellent brick work.Pressure injection into the mortar course only is less likely to be successful since the old lime mortar is very weak and often contains many fissures/that will cause the product to blow out before the new damp course is formed.
CHEMICAL IMPREGATION UNDER GRAVITY:Holes are drilled into mortar lines at regular intervals.Delivery tubes of specific design are placed in the holes and liquid is transfused into the wall under the influence of gravity.If sufficient liquid is transfused into the wall, it will form a horizontal water repellent layer in the bricks and mortar.The choice of solution is a higher alkyl siloxane in hydrocarbon solvent.
Dampness causes most of the damage to the contents of the building. It often leads to the growth of molds and bacteria and creates an unhealthy environment for those who occupy it. Dampness gradually impairs the affected part of the building so this problem should be attended as soon as possible.
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. Damp proofing with the help of chemicals may protect your house.
Brick and masonry absorb water so they must be sealed off, away from moisture and moisture-bearing substances like soil. If it does not occur, the water will rise in the walls causing dampness.

The foundation of all structures are embedded into the soil. Bricks being porous or brick masonry below ground level can absorb moisture from adjacent ground.
For residential buildings DPC consists of a layer of - 40 mm thick cement concrete 1:2:4 (1 cement: 2 Coarse sand: 4 graded stone aggregate 12.5 mm nominal size ).
For residential buildings DPC consists of a layer of-
The following table expresses the type of coating recommended for the protection of Dampness:
The density of masonry bricks used must be greater than 1200 kg/m³.
The water proofing membrane is laid out on top of the existing floor surface. It will act as a barrier against dampness.
.Dampness in buildings is a concern because it often leads to the growth of molds and bacteria
The following brands of chemical are used for the protection of dampness from building:
A damp building is unhealthy to those who occupy it, dampness in building is a concern because it often leads to the growth of molds and bacteria.
The following method should be adopted for the protection of dampness in floor:
Horizontal DPC :- All the brick walls should be covered with the horizontal DPC at the floor level.
