What are the benefits of damp proofing/tanking?


Efficient damp proofing methods ensure that you live and work in a clean environment. Apart from safeguarding the property, it also safeguards the people living in that property. For example, stagnant water or waterways on the walls can be a health hazard and can cause health challenges to the people working or living in a property that is not damp proof.

It strengthens the structure

damp proofing prolongs the lifespan of your structure by preventing waterways and moisture from entering the walls, floor or the ceiling. This will prevent rotting, corrosion, rust and the general deterioration of the building structure. Your building will remain strong for years to come.

It prevents the growth of mold

Damp proofing or tanking does not only ensure the structural integrity of a building, it also prevents the growth of molds on the building. Fungus and molds tend to grow on moist parts of a building. If not prevented the growth of these microorganisms can lead to health complications like asthma, allergies, and poor immune system.

Reduces maintenance costs

If you want to reduce the costs of repairing a building or a structure, you should consider Damp proofing it. Damp proofing is actually a cost-effective solution when it comes to saving money that would otherwise be used on expensive repairs.

It increases the value of your property

When selling your property, an inspection will be done and once it is established that your property is waterproofed, the value of the property will definitely increase. This is because damp proofing prevents structural damage as a result of water seepage. Not only does the value of your property increase but also the aesthetic appeal will also increase.

Types of Damp proofing

Cementitious damp proofing

This is by far the easiest method of waterproofing in construction. This type of damp proofing is commonly done in the interior areas of a building, for example, the toilets, kitchen, and bathrooms. It is a rigid water proofing method that requires a highly skilled professional to complete. Cementitious damp proofing is applicable to the following structures:


  • Tunnels
  • Bridges
  • Water treatment plants
  • Dams
  • Sewage treatment plants
  • Parking lots
  • Marine cargo docks
  • Railway and subway systems
Brick bet damp proofing

This type of damp proofing helps in sealing cracks and water leakages on wall structures as well as the roof of a building. It hides the ugly marks and enhances the aesthetic appeal of the building. This method of damp proofing is not as complex as the rest but it is not ideal for big surfaces.

Bituminous coating damp proofing method

This is a type of coating used for waterproofing purposes according to polymerization grade. The bituminous coating is an excellent damp proofing agent, particularly on concrete foundations. Since this type of coating is made of materials derived from bitumen, it is not suitable for structures that are exposed to direct sunlight. When exposed to prolonged sunshine, the coat becomes brittle and fragile.

Bituminous membrane damp proofing method

This is a popular damp proofing method commonly used on low sloped roofs. This method comes in two variants the torch on membrane and the self-adhesive membrane. The torch membrane method comprises two types the exposed and the covered types. The exposed membrane type features mineral granular aggregate designed to endure the wear and tear of the weather. The covered membrane is not so strong and the contractor is required to apply a protective screed in order to protect it from being punctured.

The self-adhesive membrane comprises of asphalt, filler, and polymers. It does not require additional adhesive compounds for it to be applied. However, it has a low shelf life because the bonding properties reduce over time.

The liquid damp proofing membrane method

This damp proofing method involves the use of a thin coating called liquid membrane consisting of a primer and two coats of top coats that are applied using a trowel, a roller or spray. Liquid damp proofing can be done on the roof of a building or a structure or any surface that does not require extra weight. The durability of this damp proofing method depends on the type of polymer used in making the liquid membrane.

Polyurethane liquid membrane damp proofing method

This type of damp proofing is commonly used on flat roofs and areas exposed to weathering. However, it is essential to note that this damp proofing is quite expensive but can offer higher flexibility. This method requires highly trained and experienced professionals to install it. Otherwise, it may start to peel off after some time.
