Dimpled Membrane ICF & Wood Foundations

Fast Easy Installation, User Friendly

Unroll, Fasten, Backfill.

SUPERSEAL Dimpled Membrane is clean to work with as it a plastic long lasting dimpled sheet. It is flexible enough to bend around corners but can also be cut with a standard utility knife.

Bridges Cracks / Drainage Space

With a dimple height of 5/16 inch Superseal membrane bridges over cracks and gaps. While providing a drainage space/airgap for any water that may enter the drainage space to fall by gravity to the perimeter drain for removal.

Eliminates 100% of Hydrostatic Pressure

Superseal has a compressive strength of 5200 pounds per square foot. Eliminating 100% of the hydrostatic/headwater pressure off a ICF foundation wall and onto the outside of the membrane.

Long-Lasting Basement Waterproofing Product

SUPERSEAL foundation Membrane can out last the life of the structure. It is made from high density polyethylene plastic. It will not rot and is chemical resistant. Spray on or roll on coating can start to degrade in a few years from alkaines in the soil.

Materials and tools will vary depending on your application for an ICF FOUNDATION (Insulated Concrete Form).

SUPERSEAL DETAILED INSTRUCTIONS: Installation Instructions

EXTERIOR APPLICATION:

The keys to a good installation

• Install to final grade height.
• Incorporate into the drain system at the footing.
• Ensure you have enough membrane, plugs, and molding strips to complete the area that you are protecting.
• It is better if the membrane is installed prior to installing perforated pipe and the drainstone.
• When putting the drainstone around the pipe, you must have a minimum of 6 inches around the drainpipe, on the footing and up on the membrane at the bottom.
• Follow the Installation instructions.

Addition coating(s) or a self-adhesive membrane on the wall is not required but provides additional protection. Consult with your local building official or inspector, as they determine what they will accept. This can vary from city to city.

PREPARATION

• Ensure the site is safe and accessible.
• Make sure that you have all the tools and material necessary to complete the job.
• Determine the roll heights required and measure the length needed.
• Snap chalk lines at the Determine final grade height.
• Clean the footing off and repair any imperfections.
• Use a suitable mastic or tar for patching joints, gaps, protrusions, etc. This can be found in the roofing or foundation section at most local lumber yards and Hardware stores. (Recognized as foundation mastic, roof patch, and plastic cement). The most cost effective is tar based and black in color. It is available in 1 and 5 gallon pails and also in tubes for a caulking gun. SUPERSEAL is chemical resistant and compatible with all these types of products. Low solvent or waterbased are the best. Some of these products contain higher amounts of zylene or tolene and may not be compatible with the foam. It is best to test a spot and leave for an hour or more.

PREPARING THE WALL

Prior to installing the membrane, patch all exposed joints and cracks below the chalkline, using a flat 2 or 3 inch putty knife.

Standard deck screws are used for fastening the plugs and molding. The brand of ICF will determine the length of screw to use. Most common are 1 ½ inch – 1 ¾ inch standard deck screws. A #10 or #8 Robertson is best.

All screws are to be secured into the plastic holding tabs on the ICF. These are located just below the surface. Most ICF’s are on 6 inch or 8 inch centers.

There are 3 steps to the installation – Do not try to do all three steps as you go. It is much easier and quicker to do it in 3 stages

• Hanging / Plugging / Molding

1. HANGING THE MEMBRANE

It is best to have two people and to install the membrane level. Once you have your wall prepped, start by holding the membrane at the chalk line with the dimples towards the wall and install a SuperPlug about 8-12 inches down from the top, into a holding tab. Move down the wall approx. 8 -10 feet and install another SuperPlug. Continue this process until all the membrane is hanging on the wall. Please note the membrane should be installed at only grade height as it should not be exposed to UV for long periods of time. If you have extra material at the bottom, it is flexible enough to make a 90 degree bend where the wall meets the footing. The membrane can sit directly on top of the footing or extend out to the edge. If you are extending to the edge of the footing and come to an inside or outside corner, put a slice in the membrane at the bottom to allow the rest of the roll to wrap the corner without cutting the entire roll vertically.

OVERLAPS AND SEAMS

Overlap a minimum of 6 inches for both Vertical and horizontal overlaps and put a SuperPlug every 2 feet vertically. It is good practice to run a bead of the black mastic within the overlap but is not mandatory. Overlaps in sloping areas should be done overlapping the higher piece over the lower piece. This will prevent migrating water to enter the seam. (just like a roof shingle).

ANGLES

Angles are best by installing the membrane on the wall level and cutting the top to desired angle or slope. If you cut the top, you must use the Membrane Cap. The DimpleGrip won’t fit properly. Make sure that when you cut the membrane that you start a cut where there is a holding tab.

WINDOW WELLS

If you have any windows that are lower than grade height and require a window well, cut and cap the membrane as close the bottom of the window as possible. Cut and cap the sides vertically so it will end up just inside the window well opening on each side. Vertical cuts should be made where there is a holding tab. (HINT: you can cap it later when you do the rest of the molding or cap)

After you have hung all the membrane, go back to where you started and start step 2 – plugging

2. PLUGGING THE MEMBRANE

• At the top is where you follow the specific pattern that repeats over and over. The basic pattern is; put a row of plugs 8 – 10 inches down from the top every 16 inches horizontally, into the holding tabs. Then 8 inches down for that row of plugs install another row of plugs every 16 inches into the holding tabs that are between the plugs above. This creates a W pattern. (See detailed instructions for more details)
• In the middle and the bottom, you put plugs every 6-10 feet horizontally. Enough to keep the membrane tight against the wall.  Try to get the bottom plugs as close to the footing as possible to prevent the membrane from moving around while the drain work and backfilling is being done.
• Plugs are installed every 2 feet vertically on all overlaps
• Plugs are installed every 2 feet vertically and 4-6 inches in from corners. (inside and outside corners)
• After all the plugs are in, go back to where you started and start step 3 – Molding/Capping.

3. MOLDING or CAPPING

Molding must be installed on all open edges using the Membrane Cap or DimpleGrip Molding. (See below for more details on Moldings) Start each piece in the center of a holding tab. This way it will be in the center of a tab at the end and where you start your next piece.

Once the molding has been installed, it is good practice to walk around and patch any open spots. Feel free to put in addition plugs where desired, to keep it as flat as possible on the wall.

DimpleGrip Molding is a piece of plastic 4 feet long and 3 ½ inches wide. It has reverse dimples on the back that interlock into the top 4 rows of dimples on the membrane itself. Giving a stronger hold at the top which can reduce the amount of plugs you need. It has a soft lip on it that seals the top against the wall. It fits vertically and horizontally into the factory edges of the membrane. If you cut the membrane on an angle, the dimples won’t fit properly, so you would use the Membrane Cap in that spot. You can use DimpleGrip for your entire job if your final grade is level. (HINT: We often recommend ordering both DimpleGrip Molding & Membrane Cap if your job has both level and sloping areas)

Membrane Cap is a piece of plastic 4 feet long and only 1 ½ inches wide that seals all open edges. It is L shaped and smooth on the back. It can be installed horizontally, vertically, and on any angle. You can use the Membrane Cap throughout your entire job. However, you will use more SuperPlugs below the Membrane Cap then below the DimpleGrip. (see detailed instructions)

The DimpleGrip and the Membrane Cap are in a bundle with 10 pieces that are 4 feet long equaling 40 linear feet. Both are fastened every 6-8 inches butting each piece together as you go. Both can be cut with a standard utility knife. It is not necessary to overlap them.

 

FASTENING SYSTEMS

There are two molding systems to choose from. The DimpleGrip System and the Standard System

1)      The DimpleGrip System requires DimpleGrip molding and SuperPlug. (see below)

2)      The Standard System requires Membrane Cap and SuperPlug. (see below)

DIMPLEGRIP FASTENING SYSTEM
(PREMIUM SYSTEM FOR ICF’S & CONCRETE BLOCK)

Requires DimpleGrip Molding for horizontal and vertical edges. Super Plugs fastened 12-16 inches OC and Membrane Cap for sloping areas. Small Plugs can be used to fasten corners and overlaps.

1 roll of membrane requires approximately:

• 2 bundles of DimpleGrip
• Membrane Cap for slopes and angles – 40 feet per bundle
• SuperPlugs: 2 bags for 3’6″ to 7’11” per roll or 3 bags for 8’11” to 9’11” per roll

STANDARD FASTENING SYSTEM
(MOST ECONOMICAL MATERIAL COST SYSTEM)

Requires Membrane Cap for all edges and SuperPlug fastened 8 inches OC. Small Plugs can be used to fasten corners and overlaps.

1 roll of membrane requires approximately:

• 2 bundles of Membrane Caps
• SuperPlugs: 3 bags for 3’6″ to 7’11” per roll or 4 bags for 8’11” to 9’11” per roll

SUPERPLUGS

Each plug has 5 dimples that interlock into the membrane providing superior holding strength over a single plug. Recommended for all areas.

MEMBRANE CAP

Smooth L shaped molding that caps the membrane – 40 feet per bundle.

DIMPLEGRIP MOLDING (OPTIONAL)

Interlocks with the top 4 rows of the membrane along its entire length. Provides superior strength and uses less SuperPlugs and labor.

SMALL PLUGS (OPTIONAL)

Fits into individual dimple. Used mostly for contractors with a nail gun system.
