Hollow Kick Molding

Hollow Kick Molding


A floating slab is an integral part of a subfloor drainage system, or French drain system. These floating slabs form when a basement floor slab doesn’t adjoin the foundation wall and a gap opens. This gap serves a number of functions to facilitate the subfloor drainage system, allowing it to properly do its job. Before the Hollow Kick Molding was invented, floating slabs were created by installing a temporary form against the interior side of the foundation wall.

After we remove and cure the floor slab, we take out the form. This creates a gap. Unfortunately, it wasn’t very attractive and just looked like someone ran out of cement. Additionally, it was prone to clogging when debris fell in.

The Introduction of Hollow Kick Molding

Boccia Inc. constantly strives for the best materials and methods for their Nassau, Suffolk and Queens customers. After investing years in product development, they invented, patented and produced the Hollow Kick Molding in the early 1980s. This was the first product specifically developed and designed to create the floating slab detail.

The Hollow Kick Molding is a linear floor drainage molding. We install it at the cove area where the basement floor abuts the interior side of the foundation wall. It directs water through the floor and into the drain tile pipe below, eliminating the possibility of water accumulation. A Hollow Kick Molding conceals and protects the drainage opening with an attractive cove plate molding. Not to mention, it’s the most effective, affordable method for eliminating wet basements.

After introducing it in their own work, Boccia saw tremendous interest from contractors, remodelers, developers, plumbers and waterproofers throughout the nation. Deciding to keep it proprietary in their local New York market, Boccia distributed everywhere, from Seattle to Atlanta.

Hollow Kick Molding Drainage Characteristics

The Hollow Kick Molding has successfully been installed since the 1980s. Following in Boccia’s tradition of innovation, they have recently introduced the next generation of Hollow Kick Molding with a built-in vapor retarder to reduce pollutants that may permeate the floor. This new design will still provide the same drainage characteristics that the industry has come to rely on, with the added protection of a sealed floor.

What is Hollow Kick Molding?

Hollow Kick Molding
is a linear through floor drainage molding installed at the Cove Area where the basement floor slab abuts the interior side of the foundation wall, creating a floating slab. It directs water through the floor and into the drain tile pipe eliminating the possibility of water accumulating on the floor. It also ensures proper air displacement, which will free the water flow through the sub slab piping. It also conceals and protects the drainage opening with an attractive cove plate molding.

The Latest in Water Drainage Engineering
This state-of-the-art drainage system removes water at an elevation below the floor and foundation, so the basement does not become submersed in water and hydrostatic pressure is reduced.

Why use Hollow Kick Molding?

The HOLLOW KICK MOLDING drainage system is by far the most efficient, affordable way to prevent a wet basement from ever occurring, or to assure that previously wet basements keep dry for good. With its impressive 8.5 gallons per. ft., per minute of through floor drainage, its effectiveness is unsurpassed. It installs quickly and easily thereby adding to your home or building usable space for living, working and storage.A properly installed HOLLOW KICK MOLDING drainage system will reduce the possibility of callbacks and complaints from dissatisfied customers.

Recommended Installation
Install a perforated pipe in a drainage stone envelope adjacent to the interior side of the footing. The drainage stone should be up and over the top of the footing a minimum of 1/2 inch in thickness. Lay HOLLOW KICK MOLDING on the drainage stone bed against the foundation wall. The drainage fins of the HOLLOW KICK MOLDING rest against the foundation wall with the diagonal profile at the top. Place vapor barrier and concrete floor slab on drainage stone and up against the molding. Final adjustments may be made prior to concrete cure.

Patented Design
The United States Government Patent Office has determined that the Hollow Kick Molding is the only product specifically designed to create a fully functional floating slab detail with an aesthetically pleasing concealing cove plate. (Patent # 4879851).
