Waterproofing Systems Offered

Sheet-Based Membranes

Sheet-based membranes are pre-formed products that provide robust waterproofing. These sheets are typically made from materials like PVC, TPO, or EPDM.


They are applied by adhering them to the substrate with adhesives or mechanical fasteners. This option is particularly effective for large roof areas.


The installation process requires precise alignment to avoid seams that could leak.


These membranes are known for their durability and resistance to chemicals. They can handle foot traffic and provide a reliable barrier against water.

Cementitious Waterproofing

Cementitious waterproofing is a reliable option for protecting surfaces from moisture. This system uses a cement-based mixture that can be applied to concrete and masonry.


It is perfect for areas where traditional membrane systems might not work as well.


The application is straightforward and can often be done by mixing with water and applying with a trowel or brush.


This type of waterproofing is resistant to water and is suitable for both indoor and outdoor use.


Its strong bond to the substrate helps prevent cracking and peeling over time.

Bituminous Coating

Bituminous coating is another solid choice for waterproofing. We use asphalt-based materials that create a protective layer on surfaces.


This system is applied as a thick, black liquid that forms a tough membrane when cured.


Bituminous coatings are excellent for flat roofs and areas prone to ponding water. They can withstand harsh weather conditions and provide reliable protection.


This option is often used in combination with other waterproofing methods for added security. Regular inspections help maintain the integrity of the coating.

Polyurethane Liquid Membrane

Polyurethane liquid membranes provide excellent waterproofing through a liquid-applied system. They cure to form a strong, flexible, and durable membrane on surfaces.


This type of membrane is ideal for high-moisture areas due to its superior adhesion properties.


Polyurethane systems can accommodate building movement without cracking.


They also offer UV resistance, protecting against sun damage.


These membranes are suitable for various applications, including roofs, decks, and balconies. Regular maintenance keeps the membrane effective over time.
