Schluter Deck Drainage
This page currently under construction.When it absolutely positively has to drain!
In the southeastern US we typically get more than 60 inches of rain per year. In extreme environments like this we need extreme solutions.
Here at The Aerial Companies, we use the Schlüter®-DITRA drain system which is an effective passive capillary drainage system for exterior floor and deck assemblies. This system is installed using the thin-bed method over sloped waterproofed structural decks. It consists of a closed polyethylene mat that on one side features approximately 4 mm high conical studs with a laminated filter fleece fabric on the top side.
Beach Front Estate Home - Naples, Florida
The following scopes were executed on this project by The Aerial Companies and its Subcontractors:
Water Intrusion Investigation, Demolition of Stone Toppings on all Elevated Decks / Balconies and Exterior Stairs, Balustrade Removal, Removal of Marcite Pool Finish, Structural Sloping Decks with Epoxy and Sand, Waterproofing Elevated Decks and Pool Shell with The Kemper System, Plumb New Drainage Assembly, Install Drainage Plane with Schluter Systems, Extensive Stucco Banding Repairs, Re-installation of all Stone ToppingsWater Intrusion - The Investigation
This velocity-zone pool deck and adjacent deck system is elevated above ground with a large storage area below. As a result of multiple leaks into the structure it was necessary for us to determine the exact cause of the water intrusion. The in-depth investigation process among other things, revealed a lack of proper drainage capacity under the tile deck system. Removal of Stone Toppings

Structural Sloping Decks with Epoxy and Sand
Pitch for the new slope is calculated using a Transit and then form boards are cut accordingly and laid in a pattern creating multiple rows for troweling on the epoxy / sand mixture. Prior to the application of the Epoxy a clear liquid resins is applied to the surface of the deck for use as a bonding agent. Epoxy and sand are mixed in small batches as the curing process is short. .jpg)
The mixture is then troweled on at every other row and feathered down to a feather edge. The form boards are then removed and the edges of the existing rows are used as guides for the remainder of the application. Once all rows are filled in, another coat of epoxy resin is applied to seal off the surface in preparation for the watrproofing application.
Installing the New Drain System
Not to be confused with the "drainage plane", this scope involved removing the existing and insufficient drain assembly and rebuilding a more robust deck draining mechanism within the structural slab.
Primer - First Step in the Kemper Process
After the sloped surface has been thoroughly cleaned of all latent particles – we apply a prime coat of EP primer with sand expressed into the surface to provide a bondline for the system elements to follow. Base Sheet - Kemper's Polyester Fleece
Fully Reinforced Monolithic Membrane
Kemper is a two part resin technology system – this cold-applied liquid resin combined with their polyester fleece material cures to form a fully reinforced monolithic membrane. Here we're covering the entire field of the decks with the polyester fleece. We roll on the liquid resin and lay down strips of Kemperol infused fleece which when cured forms the monolithic waterproofing membrane.After this point we add Kemper BR and aggregate as the last layer.
Surface is Waterproofed - Now ready for Schlüter®
Schluter DITRA Mat is the final layer prior to installing the stone topping. The DITRA Mat allows water to travel beneath the stone surface, through the capillaries to the deck drain mechanism.
