CSD RISE Duct Seals - Sealing Cable Ducts (Water Tight & Gas Tight)

CSD RISE Duct Seals – Sealing Cable Ducts (Water Tight & Gas Tight)

CSD RISE Duct Seals are multi-cable and pipe transit sealing systems for cable duct seals, substations and building entries where there is a requirement to prevent the ingress or spread of water, gas and fire.

CSD Sealing Systems use individual rubber insert sleeves to provide an effective but simple solution to protect against water and gas ingress with the very highest levels of long term cable sealing performance.

The RISE Duct Sealing System most commonly used is both gastight and watertight consisting of only two components:

i) RISWAT Sleeves – rubber insert sleeves used to guarantee separation of low, medium and high voltage cables and provide a backing for the sealant layer

ii) FIWA Sealant – a high quality silicone based, fire stopping and a water repellent sealant.

The CSD RISE system can also be upgraded to provide up to 4 hours of fire protection in accordance with BS EN1366-3 by exchanging the rubber insert sleeves for the fire rated RISE sleeves.

Adding, removing or replacing cables or pipes is also an easy process.

CSD RISE DUCT SEALS

Installation for watertight and gastight cable duct, substation or building entry applications:

CSD RISE WG Rapid Duct Seal

Step 1 – Ensure the cable 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 us.

Step 2  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.

Step 3 – 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.

Step 4 – 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.

Step 5 – 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. CSD RISE RAPID Duct System uses joined multi sleeves to make installation even easier.

Step 6 – 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.

Step 7 – Push filler sleeves into duct to depth of 20mm, allowing for the application of the FIWA sealant layer.

Step 8 – 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.

Step 9 – Attach the nozzle to the FIWA sealant cartridge and snip the nozzle at an angle, this will help installation. For awkward sealing applications longer nozzles and angled applicators are available. To ensure a good bond is achieved, before adding the FIWA sealant, clean the duct and cables again using the approved degreaser.

Step 10 – Using a specialist high ratio caulking gun, apply the FIWA cable and duct 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.

Step 11 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.

Step 12 – 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.

Step 13 – Use the water spray to wet your gloves, this will ensure the sealant does not stick to the gloves.

Step 14 – 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.

Step 15 – 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.

Step 16 – 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.
