RISE Duct Installation Steps
CSD Sealing Systems products are designed to be fast and simple to install, making it easier to achieve an effective gas tight and water tight seal. See below for installation instructions for RISE WG Duct Sealing system or to view a printable version click here. You can also watch online our RISE WG Duct Seal installation video.
We have a range of standard duct kits available to suit the most popular sized ducts as well as the full range of installation tools needed to ensure simple installation of our RISE Duct Seal system. The standard kits and tools can be viewed on our duct kits and tools page.
We can provide installation advice, support and training to help ensure that you are fully equipped for the task.
RISE Duct Seal
Installation for watertight and gastight cable duct or building entry applications. These instructions can be downloaded for printing by clicking here.
(These instructions are for guidance only and will be suitable for most normal applications, it is the installers responsibility to ensure that the ducts, service and environment faced is suitable and that the method can be executed correctly.)

Ensure the duct opening is clear, removing any debris which may interfere with the installation of the RISE Duct Seal. Cut off any cable ties to enable thorough cleaning of the cables and the duct. The duct should also be dry. For any running water applications please contact CSD for further instruction.
An approved degreasing wipe should be used to remove all concrete, dirt, dust and oil residues from the inside 20-30mm of the duct or building entry. Several wipes may be needed. Any cleaning residue should be removed using a clean dry cloth. To ensure a good sealant bond the duct must be clean and dry before application of the FIWA sealant.
Use the degreasing wipes thoroughly clean any dirt or oil residue from the cables or any service pipe. Cleaning of all surfaces where sealant will be applied is an essential stage to ensure that a good seal will be maintained. Before moving on check that all surfaces are clean and dry, an inspection mirror and a torch may help for any difficult to access areas.
A RISE insert sleeve is applied around each cable. The insert sleeves are split length-ways and therefore can be fitted around the cable and then pushed into the penetration to a depth of 20mm.
The remaining free space in the duct is filled using RISE blue filler sleeves type 27/19. For larger areas sleeves can be bundled together, electrical tape can be used around a bunch of RISE sleeves fixing these together. Our RISE RAPID Duct System uses joined multi sleeves to make installation even easier.
Any small gaps should be filled with 18/12 size RISE blue filler sleeves. Its important to ensure sleeves are tightly packed into the transit to create a solid base for the application of the sealant. On trefoil or multi cable configurations, space cables out in the duct, to ensure easy application of FIWA sealant.
Push filler sleeves into duct to depth of 20mm, allowing for the application of the FIWA sealant layer.
Adjustments can be made to the RISE filler sleeves using a pair of long nosed pliers. Allowing the correct 20mm depth will ensure a suitable layer of sealant is applied and a good seal is maintained.
Attach the nozzle to the FIWA sealant cartridge and snip the nozzle at an angle, this will help installation. For awkward applications longer nozzles and angled applicators are available.To ensure a good bond is made, before adding the FIWA sealant, clean the duct and cables again using the approved degreaser.
Using a specialist high ratio caulking gun, apply the FIWA sealant to the least accessible areas first (usually around cables). Apply sealant over sleeves, allowing to fill out to the required 20mm depth; a slight overfill is needed. Use a torch to check for gaps in sealant & apply more sealant if required.
When working with the FIWA sealant we recommend the use of disposable nitrile gloves. Using the water spray, dampen the cellulose sponge. This is done to stop the sealant from sticking to the sponge whilst working with it.
Using a dabbing motion, firmly pat down the FIWA sealant, ensuring the sealant makes good contact with both cable and the duct wall. For installations in vertical ducts the sealant should stand just proud of the duct; allowing any water to run off the surface without pooling.
Use the water spray to wet your gloves, this will ensure the sealant does not stick to the gloves.
The surface of the FIWA sealant should then be finished off by hand. Ensure a good smooth finish is obtained by the use of a fast skimming motion. Make sure there is a good seal around all of the cables, paying particular attention between the cables.
Take a final check with a torch to ensure sufficient sealant has been applied and the duct is properly sealed. If there are any areas that do not seem sufficiently sealed add more FIWA sealant in this area and smooth off as before. Clean any excess sealant from the edge of the duct and cables.
The completed RISE Duct Seal will provide a 1.5 bar (22 psi) water tight and 1.0 bar (15 psi) gas tight rated seal. The RISE system is proven to provide maintenance free protection for a period in excess of 50 years.
RISE Duct Seal - adding a cable
Installation instructions to add extra cables. (These instructions are for guidance only.)

Adding new cables is a simple process. The recommended RISE coring tool is used to remove a section of the sealant layer to locate an empty NOFIRNO multi sleeve. Please take care not to damage existing cables.
A hole slightly larger than the new cable should be made using the coring tool, use pliers to remove any unwanted sealant. Long nosed pliers are then used to remove some of the empty NOFIRNO multi sleeves. Insert the long nosed pliers in the sleeve and use a twisting action to remove the multi sleeve fom its strip of sleeves.
The cable is pushed into the space created. Thoroughly clean the cable using an approved degreaser wipte (De-solve-it 4000GDW) to ensure a good bond will be made with the sealant. A correctly fitting RISE FRR/LEHF sleve must be put around the new cable.
Pack with additional NOFIRNO multi sleeves if required. Smaller 18/12 sleeves can be used for smaller gaps.
Refill the opening cut in the sealant layer with sufficient sealant. A slight overfill is required.
Finish the sealant layer in the usual way. Using nitrile gloves, pat the sealant down with the damp sponge. With wet gloves, smooth the surface of the sealant by hand and inspect with the torch to complete the installation.
