Drainage Solutions with Wykamol CM Accessories

The CM Accessories range from Wykamol forms the critical backbone of any Type C cavity drain membrane waterproofing system. Designed to ensure watertight, maintainable, and BS8102:2022-compliant installations, these accessories include fixings, drainage channels, jetting components, corner pieces, outlet fittings, and specialist sealing products. Each component is manufactured to integrate seamlessly with Wykamol’s CM membranes, delivering a unified system that supports the safe management of water ingress in below-ground environments. Whether you’re converting a basement, tackling damp walls, or waterproofing new builds, CM Accessories provide the precision and durability demanded by professionals and DIY users alike.

Secure and Watertight Fixings for CM Membranes

Wykamol’s CM Brick Plugs and CM Plaster Plugs are purpose-built fixings designed to anchor cavity drain membranes to various substrates, including brick, block, stone, and concrete. Available with or without waterproof seals, these plugs ensure the membrane remains securely fixed while maintaining an essential watertight barrier. The large plug heads offer generous surface areas for dot and dab plasterboard or traditional plaster finishes. Thermoplastic elastomer seals are tailored to fit each plug type perfectly, providing reliable resistance against water ingress especially in retrofit waterproofing applications where internal walls are susceptible to damp.

Drainage Control with Perimeter Channels

Efficient water management is central to any Type C waterproofing system, and the Wykamol Waterguard and Floor Drain Channels ensure this is achieved with precision. The Waterguard Channel, featuring an integrated upstand flange, is fitted around the perimeter of floors where walls meet slabs — a critical junction for water ingress. The Floor Drain Channel, with its flangeless profile, is ideal for use across central floor areas or where stepped foundations present installation challenges. Both are manufactured from durable PVC, pre-drilled for drainage efficiency, and engineered to be compatible with all other Waterguard accessories.

Jetting Access and Maintenance Product

A robust waterproofing system must remain serviceable over time. Wykamol’s range of jetting eyes and inspection components including the Jetting Eye (2″ waste) and Flexible Jetting Eye, allow for cleaning and maintenance access at regular intervals. These components help prevent the build-up of lime scale or silt and reduce the risk of future blockages. The Swept Corner Piece, with its smooth curved design, ensures a continuous flow through internal or external corner transitions, supporting system integrity and prolonging the lifespan of the installation.

Integration with Connectors and T-Piece

To form a continuous and adaptable drainage system, Wykamol offers several joining and connection components. The Jointing Section enables push-fit connections between straight channel lengths, while the T-Piece allows cross-floor water diversion or direct connection to sump chambers. These simple-to-install parts support the installer’s need for flexibility, especially on projects with irregular layouts or existing structural constraints. No special tools or additional connectors are required, allowing for rapid assembly on site.

Outlet Products

Proper removal of collected water is critical in below-ground waterproofing. The Waterguard 50mm Outlet and the Universal Channel Outlet are designed to efficiently channel water from the drainage system to a sump chamber, external gully, or natural drainage point. Both fittings offer push-fit installation and are built from tough PVC for long-term durability. The 50mm Outlet suits compact installations, while the Universal Channel Outlet, with its 100mm outlet and integrated jetting access, provides a high-capacity solution ideal for commercial or high-water-risk settings. Each is fully compatible with Wykamol drainage channels and supports compliance with BS8102:2022.

Accessories

Additional elements in the CM Accessories range such as Brick Plug Seals and Plaster Plug Seals are essential for enhancing system performance. Manufactured from flexible neoprene, these seals are designed to compress tightly around plugs during installation, creating a moisture-resistant seal behind the membrane. Available in large pack sizes, these accessories are suitable for both small residential jobs and large-scale commercial installations. Their ease of use, combined with tailored design, makes them ideal for contractors looking for reliable, professional-grade materials.

Below-Ground Waterproofing

Wykamol’s CM Accessories are engineered to meet the needs of architects, structural waterproofing contractors, and renovators undertaking critical damp-proofing and basement conversion work. Every item within the range plays an essential role in supporting a robust cavity drain membrane system, from the smallest seal to the largest outlet fitting. By using Wykamol’s complete system, installers ensure long-term protection against water ingress, structural movement, and future maintenance issues.

From initial fixings to final water discharge, CM Accessories provide a reliable, fully integrated approach to below-ground waterproofing. When used alongside Wykamol CM membranes, sump pumps, and insulation layers, the result is a compliant, dry, and secure interior space.
