Area-Specific Building Waterproofing Services At Neptune

Bathroom and Kitchens

We use cement-based waterproofing material for internal wet areas like bathrooms and kitchens. This is the quickest residential waterproofing solution.

Balconies, Terraces and Parking Lots

We cover and waterproof complex surfaces with liquid membranes. This is the ideal waterproofing method for roofs, balconies and terraces because of its flexibility.

Foundations and Retaining Walls 

We give protective waterproofing coats to foundations and retaining walls with asphalt-based materials. This is one of the most effective moisture barriers for concrete areas. 

Low-Slope Roofs

We also waterproof low-slope roofs and underground structures using bituminous membranes. This method provides a strong protective layer that is super water-resistant. 


We use Ethylene Propylene Diene Monomer (EPDM) Rubber and crystalline waterproofing methods for basements. These are suitable methods for foundations and roofs as well.


We perform injection grouting to fill visible cracks in foundations, tunnels, and basements. As waterproofing experts, we recommend injection grouts to repair and seal leaks in concrete structures.

Which waterproofing services do you provide?

We provide waterproofing services for different areas of residential and commercial properties including roof, basement, kitchen and bathrooms, foundation and exterior walls.

How much do waterproofing solutions cost?

While we need to inspect the property and degree of damage to give you a ballpark figure, we can say that the costs of waterproofing depend on size and condition of the area you would like to waterproof, the type of waterproofing method, the material required for the process, and the additional repairs and preparations needed for the process.

How long does the process of waterproofing take?

At Neptune Construction Inc. we typically take between 3 to 8 days for waterproofing a specific area. But the timelines significantly depend on the area we waterproof, for example, basement waterproofing takes more time than roofs.

How do I know if my property needs waterproofing?

Typical signs that your property may require waterproofing include water stains, dampness on walls, wet ceilings, growth of mildew and mold, visible cracks, water pooling and musty odors. Again, it is ideal to go for a formal inspection to find out which specific areas need waterproofing.
