The installation of a roof drain outlet will play a crucial role in ensuring that rainwater is filtered away from your roof rather than being allowed to ‘pond’ and then eventually seep into the building.
At Wallbarn we stock an excellent roof drain outlet range, including outlets, vents and accessories, all of which are designed to offer effective and lasting relief from the effects of water damage.
The drain connectors, roof drain outlet range and collars available from Wallbarn are made in a number of different materials, it is therefore vitally important that installers and specifiers select the correct material when ordering products, customers will need to ensure that the material used is compatible with the waterproofing system being laid.
Why Use a Roof Drain Outlet?
As rain falls onto a roof, the rainwater spreads out until it reaches the lowest level that it can find. This is why roof drain outlets are required across the roof, allowing the water to escape to prevent it entering the structure.
As the depth of water on the roof or gutter increases, it generates a force to move the water flow towards holes or openings called roof drain outlets that convey the water to a lower level. The roof drain outlets are connected to pipes that drop to ground level and into the underground drainage system.
Since a vast amount of rainwater will fall onto the roof deck and be channelled into the roof drain outlet, it is essential that this rainwater cannot find its way behind or beneath the waterproofing membrane at crucial points. Obviously the outlet holes are the most vulnerable parts of the waterproofing and as such we offer a range of products designed to ensure that this does not happen.
Range of Roof Drainage Solutions Available
Wallbarn offers a range of roof drainage products with outlets available to drain different types of roof construction (warm roof, cold roof, inverted roof), for installation in different types of deck (concrete deck, metal deck, wood deck) with different types of waterproofing membrane (mastic asphalt, built-up felt, single ply).
At Wallbarn we supply many types of roof drain outlets to ensure a watertight connection between the water/damp proofing membranes and the drainage pipe work, thereby removing the problem of water penetration at this crucial junction.
Many of our roof drain outlets provide a ready made, engineered, sump that is mechanically sealed to the membranes and then connect that sump securely to the pipe work.
We have a number of different products to cater for the drainage and aeration requirements for a waterproofed concrete roof:
- Drain connectors for circular downpipes cast in the middle of the concrete deck
- Corner fittings for holes on the junction of horizontal and parapet wall
- Collars, to fit around pipework which is emitting from the deck
- Vents and aerators, which draw vapour out of the concrete
- Accessories, including leaf guards, corner patches and extensions
