Introduction & Uses

Flexseal have designed a range of lateral connection saddle products specifically for Twin Wall pipes to ensure the market has an ‘off the shelf’ solution for the most common connections. Flexseal’s range of Twin Wall saddles ensure an airtight and watertight seal between a Twin Wall pipe and a smaller lateral (or branch) pipe.

To ensure Flexseal offers its customers piece of mind, all saddles for Twin Wall pipes hold WRc Approval, an independent fitness-for-purpose testing certificate.

Saddles offer the same solution as pipe junctions, for example, lateral pipes from new build houses, road gullies etc need to be connected into the system mains. Both saddles and junctions offer this connection but with clear differences in the installation methods.

Junction method: excavation of the existing main pipeline around the entire external surface area, a section of pipe cut and removed, and pipe junction lifted into place and connected.

Saddle method: excavation to a small top section of the main pipeline, a core hole created and the saddle connected into the cored hole.

Here are some of the main benefits:

Lower materials cost – the larger the pipes the greater the savings become
Savings in labour time and cost
Significantly reduced excavation requirements
No heavy lifting equipment required
Improved health & safety

For Twin Wall DN300-600

Twin Wall pipes from DN300 – DN600 can be connected into using a suitable Flexseal PA (Pipe Adaptor) Saddle.

The range of Flexseal PA Saddles are used to connect a 160mm outside diameter PVC lateral (or branch) pipe into a larger diameter Structured or Twin Wall sewer or surface water pipe.

By coring a hole at 177mm, the Flexseal PA Saddle can be installed in minutes, followed by the insertion of a 160mm PVC lateral pipe into the PA Saddle. The range boasts a variety of different sizes to cover the most common pipe sizes.

Here are some of the main benefits:

Can be used in conjunction with a lateral pipe adaptor to connect any DN100 or DN150 lateral pipe
Lower cost in comparison to junctions
Reduces labour time
Small and lightweight, easy to store and transport
Position the lateral connection wherever a cored hole can be made
Withstands internal bar pressure of up to 0.5 bar
WRc Approved™

Quick Tip: The PA Saddle will accept a 160mm PVC lateral pipe as standard, however, the saddle can be made universal by adding a Lateral Pipe Adaptor. The adaptor can be installed into the saddle which can branch off to fit a different material DN150 pipe or a smaller DN100 pipe.

For Twin Wall DN700 and above

Twin Wall pipes from DN700 and above can be connected into using a suitable Flexseal UA (Universal Adaptor) Saddle.

The Flexseal UA Saddle is used to connect a DN150 lateral pipe into a larger diameter Twin Wall, Weholite or Ridgistorm sewer or storage pipe.

By coring a hole at 177mm, the Flexseal UA Saddle can be installed into a Twin Wall main pipe from DN700 and above. A DN150 branch connection can then be installed using a suitable Flexseal coupling.

The Flexseal UA Saddles contain spacer rings which are interchangeable depending on the application. Flexseal prepare all UA Saddles to order to ensure they are application ready prior to delivery.

Here are some of the main benefits:

No adhesive, sealant or concrete required
Eliminates need to pre-order a factory made junction
Reduces costs, whilst increasing installation options
Minimises time exposed to live sewers
Installation unaffected by weather conditions
Lightweight, easy to handle for quick installation
Robust and should not be damaged under normal site conditions

WRc Approved

The WRc Approved™ scheme is recognised and established within the construction industry; providing suppliers, buyers and end-users confidence that the products are fit for purpose. The scheme reduces risks in procurement by ensuring quality, performance and installation processes have been tested with the most stringent of requirements, in conformance with BS EN 295 and BS EN 16397.

Flexseal can offer a range of Twin Wall lateral connection products which carry the assurance of WRc approval. Saddles, when compared with factory made junctions, can offer a multitude of benefits both in procurement and on-site in areas such as H&S, labour, installation time, flexibility and cost.
