⦁ In-depth understanding of international waterproofing standards and compatibility with multiple product systems and suppliers

⦁ Implementation of documented quality and safety procedures specific to waterproofing works

⦁ Execution of torch-applied membrane systems in challenging environments, including roof and green space applications

⦁ Application of liquid protective coatings via spray, roller, or hand techniques

⦁ Use of high-pressure airless spray systems, operated by trained personnel

⦁ Availability of a comprehensive fleet of company-owned application and installation equipment

Sheet Membranes

CRL is experienced in the installation of both bonded and unbonded sheet membranes, with a focus on applications in the civil infrastructure sector. Unbonded membranes provide benefits such as faster installation and uniform material thickness. Bonded or cast-in membranes are increasingly adopted for their enhanced sealing and durability when compared to traditional coatings.

Torch-Applied Membranes

These systems are suitable for demanding environmental conditions, offering durability, UV resistance, and protection against root penetration. CRL personnel are certified by a range of material suppliers for the installation of torch-on systems.

Liquid-Applied Coatings

Liquid coatings are applied using spray, roller, or hand methods, and are particularly effective in detailed or irregular geometries where sheet membranes may not be practical. Applicators are trained and experienced in handling a wide range of protective coating products.

Joint Repairs

CRL performs remediation of failed expansion and movement joints, including removal of degraded sealants and installation of new, compatible systems. All works are executed with consideration to the original substrate and environmental conditions.
