Wall Dam G3 installation options: 

(each option requires slightly different components)

Choose Installation Type 

Start by looking at the inside of your garage to decide what is the best solution to install Wallr Dam either wall to wall, catchment, or catchment to wall.

Examples of Wall Dam Configurations

Step 1 

Clean and prepare area 

Clean the shed or garage floor surface and remove any objects that will obstruct your installation area. This includes any uneven surfaces which could affect the Wall Dam seal attaching to the floor.

 

Step 2 

Measure and cut lengths required 

Cut the Wall Dam to length safely using the appropriate tools. A drop-saw with a tungsten tip aluminium saw blade will result in a cleaner, more accurate cut than either a hacksaw or a grinder. Use a file to remove any burrs

Step 3 

Check and mark your placement 

Place your Wall Dam assembled with any straight joiners and corner catchments into position. We recommend placing Wall Dam 50mm away from any garage door guide tracks. A chalk line will give you an accurate placement. Check and mark where you are going to fix your screw to the floor. We recommend 50mm at each end of the Wall Dam
length and approximately 300mm between each screw along each entire length.

See Diagram. For corner setups, you will be provided with a 150mm Wall Dam return leg to meet your wall. Mark under 50mm from each end for drilling. This should be enough length, along with the corner component, in most cases to install the main length of the Wall Dam past any garage door guide tracks. The catchment kit will provide two screws for the return leg and one screw for the corner component.
Mark the corner component for drilling at the centre right angle.

Step 4 

Pre-drill and drill

Using your cordless drill with a 1/4” metal drill bit, drill through your markings on the Door Dam. Once the holes are drilled into your Door Dam, place back into position and use holes to mark your concrete. Remove Wall Dam from the marked position and use a masonry drill with a 3/16” drill bit to drill the concrete to match the depth of your screws. Clean the concrete surface with a good vacuum cleaner once the drilling is complete.

Step 5 

Insert cup seals 

With your Wall Dam assembled, turn all the components upside down. Check all joins are butted up next to each other and start inserting the two lengths of cup seal along the whole length of the Wall Dam. The cup seal must remain in one piece along the length of the Wall Dam aluminium carrier for water sealing efficiency. Cut any excess cup seals at each end to be flush with the Wall Dam ends. Then flip your Wall Dam back into position for installation.

Step 6 

Fixing your Door Dam to floor 

Important! If your concrete floor has grooves, cracks, joins or uneven surfaces, silicone should be generously applied to the underside central area (where the fixing holes) are on the bottom of the Wall Dam just before installation. Once you have your Wall Dam in its final position, we highly recommend that you inject silicon at each end of each length and all moulded corners when joining pieces. Water is insidious stuff, and it will try to beat you any chance it can.

Use a cordless drill with a 5/16” Tek bit to fix your Wall Dam to the concrete. DO NOT over-screw the fixings. Wipe away any excess silicone for a cleaner appearance.

Step 7 

Insert yellow strip 

Layout your provided yellow strip to measure and cut the required length. If you are installing Wall Dam with corners, you will need to cut the yellow strip at a 45-degree angle as neatly as possible with a strong pair of scissors.

The yellow strip will now need to be inserted into place starting from one end to the other to complete your installation. 

The yellow strip is removable for temporary use of housing low voltage cables to protect against damage from vehicles.
