Installing the Kemper System for a Green Roof!

Installing during December in Maine is not easy with a product like this.

Green roofs are considered an integral part of a sustainable building strategy. Kemper System offers a single-source warranty for green roof assemblies comprised of liquid-applied waterproofing membrane, insulation, drain mat, retention mat, filter sheet, growing media and in some instances, the plantings as well.

Kemper Systemís monolithic, seamless, rot and root resistant membranes can accommodate virtually any roof landscaping design offering long-term peace-of-mind solutions for extensive landscaped green roof overburdens.


Odor-free assembly for sensitive areas and occupied buildings
Monolithic, seamless membrane that fully adheres to the surface
Rot and root resistant, impervious to bio-deterioration
Carries overburden such as growing media, pavers, etc.
For extensive green roof design and  planters
Up to 80 % renewable resource content
Single-source warranty on the full roof assembly
Stripping in the seams of the plywood with Kemper. Also, wrapped up the face of the step with kemper. This product is perfect for applications like this. There are no seams. It is completely monolithic once installed. This job posed a challenge because it was under a tent in the winter time. We had to work around all of the staging legs. Priming the surface, letting it dry, then putting the membrane on, letting that dry, then moving the staging over and repeating! It was technical to say the least.

Another picture of the water proofing membrane used to reinforce the joints of the plywood. The plywood has a primer on it. The Liquid Kemper is applied to the joints with fabric embedded in it. Then another layer of liquid kemper is applied on top of that.
This is a good picture showing the fleece fabric being rolled out with the final layer of liquid kemper applied to it.
This shows a typical corner with the fleece being precut to accept the kemper liquid resin. The plywood is primed.

My experience with kemper I see the following benefit over traditional EPDM rubber roofing.

  • 25 Year Warranty which includes removing rooftop decking or green roof materials. For a residential application with a rooftop deck or green roof you would be lucky to get a 5 year warranty with EPDM.
  • There are no seams
  • The material self terminates so there is no fasteners or adhesives needed.
  • Should be used in the areas where a leak can’t be afforded. Any deck over living space, green roof, patio, terrace, even on highend homes with flat roofing who don’t want to have to service their roof and want to get it done once without having to think about it down the road.

Installing Below Grade Ruberized Waterproofing Membrane

This picture Shows the angle used to match the grade line.



This project was done doing the later fall before winter set in and we had cold temps to deal with.  These types of products really like to be installed above 30 degrees.  This is an asphalt based rubber waterproofing membrane.  This type of waterproofing is very good in our climate because it stretches.  As the foundation goes through its freeze and thaw cycle cracks appear over time.  This type of membrane will help to bridge those gaps over time giving the waterproofing membrane a longer life and keeps your basement dry.

Quantum Performance Building Products is a full service insulation and waterproofing company.  We offer a full range of waterproofing products.  Some of our products are listed below.

1.) Fully Rubberized Waterproofing Membranes

2.) Above Grade water and air barriers.  Both sheet and fluid applied.

3.) Protection panels to cover our water proofing products.  This product is very important to the waterproofing system.  It is a fiber board that creates a barrier between the dirt and waterproofing membrane.  Over time, rocks and dirt run up against the membrane and can shorten its life if its not protected with a boar.

Adding a Protection/Drain Panel really helps with the overall lifetime of the membrane.

Maine Spray Water Proofing

In construction, a building or structure is waterproofed with the use of membranes and coatings to protect contents as well as protecting structural integrity. The waterproofing of thebuilding envelope in construction specifications is listed under “07 – Thermal and Moisture Protection” within MasterFormat 2004, by the Construction Specifications Institute, and includes roofing material as well as waterproofing materials[citation needed].

In building construction, waterproofing is a fundamental aspect of creating a building envelope, which is a controlled environment. The roof covering materials, siding, foundations, and all of the various penetrations through these surfaces need to be water-resistant and sometimes waterproof. Roofing materials are generally designed to be water-resistant and shed water from a sloping roof, but in some conditions, such as ice damming and on flat roofs, the roofing must be waterproof. Many types of waterproof membrane systems are available, including felt paper or tar paper with asphalt or tar to make a built-up roof, other bituminous waterproofing, EPDM rubber, hypalon,polyvinyl chloride, liquid roofing, and more.

Walls are not subjected to standing water, and the water-resistant membranes used as housewraps are designed to be breathable to let moisture escape. Walls also have vapour barriers or air barriers. Damp proofing is another aspect of waterproofing. Masonry walls are built with a damp-proof course to prevent rising damp, and the concrete in foundations needs to be damp-proofed or waterproofed with a liquid coating, basement waterproofingmembrane (even under the concrete slab floor where polyethylene sheeting is commonly used), or an additive to the concrete. A potential problem in earth sheltered houses is too much humidity, so waterproofing is critical in these houses. Water seepage can lead to mould growth causing significant damage and air quality issues. Properly waterproofing foundation walls is required to prevent deterioration and seepage.

The penetrations through a building envelope need to be built in a way such that water does not enter the building, such as using flashing and special fittings for pipes, vents, wires, etc. Some caulkings are durable, but many are not a reliable method of waterproofing.

Also, many types of geomembranes are available to control water, gases, or pollution.

Over the past two decades, the construction industry has had technological advances in waterproofing materials, including integral waterproofing systems as well as more advanced membrane materials. Integral systems such as hycrete work within the matrix of a concrete structure, giving the concrete itself a waterproof quality. There are two main types of integral waterproofing systems: the hydrophilic and the hydrophobic systems. A hydrophilic system typically uses a crystallisation technology that replaces the water in the concrete with insoluble crystals. Various brands available in the market claim similar properties, but not all can react with a wide range of cement hydration by-products and thus require caution. Hydrophobic systems use fatty acids to block pores within the concrete, preventing water passage.

Sometimes the same materials to keep water out of buildings are used to keep water in, such as pond or pool liners.

New membrane materials seek to overcome shortcomings in older methods like PVC and HDPE. Generally, new technology in waterproof membranes relies on polymer-based materials that are extremely adhesive to create a seamless barrier around the outside of a structure.

Waterproofing should not be confused with roofing since roofing cannot necessarily withstand hydrostatic head while waterproofing can.

The standards for waterproofing bathrooms in domestic construction have improved over the years, due in large part to the general tightening of building codes.
