Method

One system per project, not one product for everything.

Mauritius has many microclimates. Riteseal provides professional roof waterproofing across Mauritius and Rodrigues using cold-applied acrylic, hybrid polyurethane, pure polyurethane and cementitious systems.

Coastal regions are generally hotter and drier, with strong UV and salt-laden air, but can still experience heavy rainfall. The Central Plateau is usually cooler, wetter and more humid, with more frequent rain and longer drying periods.

The application also matters. An exposed roof or concrete slab faces different conditions from a wet room, balcony, basement, retaining wall, swimming pool or water tank. Each area may require a different level of UV resistance, flexibility, water-pressure resistance, durability and compatibility with finishes such as tiles.

Our applications also cover: Walls & Masonry, Stone & Façade Protection, Foundations & Retaining Walls, and Behind Stone & Rock Finishes, using bituminous waterproofing or a silane-siloxane water repellent depending on the substrate.

Riteseal considers:

After inspection, we specify the most suitable waterproofing system, whether acrylic, hybrid PU, pure PU, cementitious, bituminous or a silane-siloxane water repellent, and apply it using trained, supervised teams. Our systems are cold-applied, with no open flame and generally no need to vacate the building.

What we assess

  • Local climate and exposure
  • Type and condition of the substrate
  • Cracks, joints and structural movement
  • Roof slopes, drainage and ponding water
  • Whether the area is exposed, tiled, submerged or trafficable
  • Positive or negative water pressure
  • The intended use of the area
  1. 1

    Inspect

    Substrate survey, slopes, detail points, residual moisture.

  2. 2

    Specify

    System, thickness, primers, associated warranty.

  3. 3

    Execute

    Preparation, controlled application, handover with photo report.

Which system for your project?

Acrylic

Best for

Exposed roofs with good drainage, reflective roof systems and cost-conscious projects

Key benefits

Cost-effective, UV-resistant, highly reflective, breathable and easy to maintain

Typical warranty*

5–8 years*

Hybrid polyurethane

Best for

Residential, commercial and industrial roofs

Key benefits

Excellent flexibility, seamless waterproofing, outstanding weather resistance and excellent value for money

Typical warranty*

8–10 years*

Pure polyurethane

Best for

High-performance roofs, complex roof details and areas exposed to occasional ponding

Key benefits

Premium seamless waterproofing, exceptional elasticity, superior crack-bridging and maximum long-term durability

Typical warranty*

12–15 years*

Cementitious

Best for

Bathrooms, balconies, swimming pools, water tanks, basements and retaining walls

Key benefits

Excellent adhesion to concrete and masonry, suitable for damp substrates and applications subject to positive or negative water pressure (depending on the system specified)

Typical warranty*

8–10 years*

Bituminous waterproofing

Best for

Foundations, retaining walls, concrete and masonry walls, concealed surfaces, and walls that will later receive natural stone, rock cladding or other decorative finishes

Foundations • Retaining walls • Concrete & masonry walls • Behind stone or rock finishes • Planters • Concealed waterproofing applications

Key benefits

Provides a continuous protective moisture barrier on concrete and masonry surfaces, including behind finishes or cladding

Bituminous waterproofing treatments are generally supplied without warranty due to the nature of the application and because treated areas are often concealed, covered, backfilled or subsequently finished. Any warranty, where applicable, will be specifically stated in the quotation.

Typical warranty*

No standard warranty

Silane-Siloxane water-repellent treatment

Best for

Exposed natural stone, concrete, masonry, brickwork and façades where a clear, breathable water-repellent treatment is required

Natural stone • Exposed concrete • Masonry • Brickwork • Façades • Porous mineral surfaces

Key benefits

Penetrates porous mineral surfaces to reduce water absorption while allowing water vapour to escape and maintaining the natural appearance of the substrate

A water-repellent treatment, not a membrane waterproofing system. Not suitable for active water leaks, structural cracks, hydrostatic pressure, permanently submerged areas or situations requiring a continuous waterproofing membrane.

Typical warranty*

Project-specific / subject to substrate condition and product specification

*Not every system carries a standard warranty: some have standard warranties, some project-specific warranties and some no standard warranty. Typical warranty periods shown are subject to the complete waterproofing system specified, substrate condition and preparation, correct application, site conditions, and compliance with Riteseal's Warranty Terms & Conditions and maintenance requirements. Please refer to our Warranty page for full details. View the Warranty page.

Expansion joint treatment.

Expansion joints absorb the natural movement of a building: thermal expansion, concrete shrinkage and vibration. They are also the single most common point of water ingress on a flat roof. A joint treated as an ordinary crack will simply reopen with the first heat cycle.

Riteseal treats expansion joints as a dedicated detail: opening and cleaning the joint, installing a backer rod, applying a flexible elastomeric sealant, then reinforcing the zone with a polyester fabric embedded in the liquid waterproofing membrane. The result stays watertight while remaining free to move.

  • Joint opening, dust removal and substrate-specific primer
  • Backer rod sized for correct sealant geometry
  • Flexible elastomeric sealant with high elongation
  • Polyester reinforcement strip embedded in the liquid membrane
  • Same approach for roof, terrace and slabs

Guides: bituminous waterproofing and silane-siloxane water repellents.

Foundations, retaining walls, walls behind stone cladding, or exposed stone and façades: learn when to use bituminous waterproofing and when a clear silane-siloxane water repellent is the better choice. A correct roof slope (ideally 2%) also reduces ponding water, which can shorten waterproofing performance.
