Cheapest Waterproofing method is essential in areas where heavy rainfall occurs. Moreover, basements and foundations should also be covered with thick coatings of moisture-resistant chemicals. For an average consumer, the costs of hiring a waterproofing agency is out of bounds because of the auxiliaries, workforce, and chemicals used in the process. However, a possibility is always there.
In this blog, we will provide the most economical waterproofing methods that you can avail of.

Liquid Membrane Waterproofing
Chemically-induced waterproofing membranes are elastic in nature, requiring full bonding on the substrates, such as concrete, tile, etc. Their application prevents the water from seeping through or circulating through the layers, keeping the interior safe from moisture. Liquid waterproofing is applied with rollers, spray, or brush.
According to experts from Waterproofing.pk, a primer should be used to increase adhesion with the membrane. Due to its viscosity, the penetrating effects are visible after the final coating is applied. However, with cementitious coatings, a bonding slurry (addition of extra water to the product) is necessary.
Liquid applied waterproofing membranes cure at different rates because of various reasons, such as humidity, ambient temperature, porosity, air flow, etc. The minimum drying (curing) time is 1-3 days.
Properties
- Crack-bridging ability
- Breathability
- UV-resistant
- Anti-microbial growth
- Easy application
- Cost: On average, per sq. ft. of liquid membrane application costs Rs. 50-100
N.B. The final price depends on the coat thickness and paint quality.

Polymeric Membranes
Polymeric membranes are synthetic semi-permeable sheets based on glassy or rubbery polymers. Classified as one of the newest technologies in the waterproofing industry Cheapest Waterproofing Method are suitable for all types of roofs, especially diffuse membranes. Others are PVC and PDM-diffuse membranes.
Polymeric membranes are tested and checked by experts. The useful life of the anti-condensation membrane (polymeric) is 25 years. Being an eco-friendly product for users, it is regarded as a permanent solution for leakage, seepage, or moisture ingress.
Properties
- Quick curing period
- Fire-resistant
- Easy to use
- Cost: On average, 0.5um membrane costs Rs. 300-500 per meter.
N.B. The price depends on the membrane’s thickness

Integral Waterproofing
Integral waterproofing is applied during the construction phase. Based on the structure’s lifetime cost, this method is inexpensive and popular. Homeowners or builders can manage their work with liberty, without concerns of leaking or seepage. The process involves the use of chemicals to reduce ‘green concrete’. Three types of chemicals are used in the concrete:
-
Densifiers
Silicates or silica fumes are used to fill the pores to block the water passage.
-
Water Repellant
The hydrophobic polymers cover the pores and hinder the flow.
-
Crystalline
The chemical makes non-soluble crystals when in contact with water. The crystals stop the water ingress or seepage.
Properties
- No specific skills required to apply
- Long-lasting
- Quicker to implement
- Cost: On average, 1 liter is priced at Rs. 800-1400

Cementitious Waterproofing
Cementitious coatings are useful for positive and negative side waterproofing. It is applicable on tile (back-side), patches and concrete surfaces. The polymer modifier adds to the flexibility. The coating protects the substrate from acid attacks, moisture, and toxic chemicals. Moreover, the linear movement of the concrete is managed with cementitious coating.
It is used for top and underground structures, roofs, and decks. Apart from that, it helps protect coastal structures and highways. Other areas include tunnels, parking spaces, sewage systems, and water treatment plants.
Properties
- Simple to use
- Strong adhesiveness to different surfaces (porous and non-porous)
- Breathable
- Avoid water penetration through hairline cracks and pours
- Cost: On average, a bucket of cementitious Cheapest Waterproofing Method (19kg) for 700 sq. ft. costs Rs. 8000 – 10000
N.B. The cost depends on the paint quality and thickness.
Conclusion
Opting for the most economical waterproofing method is a feasible option for most homeowners, especially in times of high inflation and taxes. If you cannot take a final decision, connect with a reliable firm like Waterproofing.pk and talk to their experts.
