DOYMA Fibre Cement Sleeve

Fibre Cement and Steel Sleeves by DOYMA

FIBRE CEMENT CURAFLEX® SLEEVES

Wherever services are installed through walls, ceilings or floors, penetrating water and gas may cause damage to buildings, along with its contents and inhabitants. Lack of attention to the points of entry of pipes and cables into the building can have serious results. These problems could be damp cellars, equipment damaged by water ingress or lack of chemical resistance, resulting in high repair costs.

The DOYMA Plates, Sleeves and Puddle Flanges are the perfect solution for all your sealing protection needs. They are available in a large range of standard sizes and types, and can also be custom made to meet specific requirements. We can supply wall mounted Plates, along with a range that can be cast into a wall during the construction phase, as an alternative to core boring through an existing wall.

The external waterproofing or level of gas tightness required dictates the type of the sleeve, plate or puddle flange that you will need. The DOYMA Curaflex® range comes in two materials, fibre cement and steel, both with different features.

The DOYMA Curaflex® Gaskets are designed to fit inside the Sleeves, Flanges, or the spigots on the Plates.

Fibre cement sleeves are designed to be cast into waterproof concrete where they create a homogeneous and watertight connection. This prevents shrinkage cracks and is dimensionally stable. Fibre cement sleeves are optimally designed to be used in conjunction with the Curaflex® gaskets.

Curaflex® 3000 Sleeves are made of a high-quality special fibre cement and have a large surface area for casting into waterproof reinforced concrete structures.

They are designed for flush mounting into the formwork and can also be provided as a split version (Curaflex 3000/T), for retrofit, where services are already installed.

Curaflex® 3001 Sleeves are also made of fibre cement for casting in, but in addition have a large fixed flange to maintain the integrity of liquid form waterproof sealants that may be used on the surface of your wall to be penetrated.

Curaflex® 4006 Sleeves are also made of fibre cement for casting in, but in addition they have fixed and loose flanges made of cast iron to maintain the integrity of a tanking membrane or thick waterproof coating.

Curaflex® 9000 Puddle Flanges are designed to be cast into a waterproof concrete structure. With a framework flush mounting, their inner wall is optimally designed to accommodate DOYMA gaskets. The 100mm steel flange can be welded at any point along the sleeve.
