Homegrown European Larch for Environmental & Water Management Projects

Homegrown European Larch Suppliers

Lanlee Supplies are specialists in sourcing and supplying homegrown European Larch for environmental, ecological and civil engineering projects throughout the UK.

We work closely with UK sawmills to procure large quantities of homegrown larch in a wide range of section sizes, supplying projects from small habitat improvements through to major flood management and environmental infrastructure schemes.

Where project specifications prohibit the use of preservative-treated timber, untreated homegrown European Larch offers an excellent naturally durable solution for many freshwater applications.

Whether your project requires structural posts, rails, bearers, boards or bespoke machined components, our experienced team can source and supply the material you need.

Why Specify Untreated Homegrown European Larch?

European Larch (Larix decidua) has long been recognised as one of Europe's most naturally durable softwood species.

Unlike pressure-treated timber, untreated larch relies upon its naturally occurring resins and heartwood durability, making it particularly suitable for many environmentally sensitive applications where chemical preservatives are undesirable or prohibited.

Typical benefits include:

• Naturally durable softwood.
• No preservative treatment required for many above-ground external applications.
• Suitable for many environmentally sensitive freshwater projects.
• Attractive natural appearance that weathers to an even silver-grey finish.
• Excellent strength-to-weight ratio.
• Sustainably sourced from UK forests.
• FSC® certified material available where specified.
• Available in large structural sections.

Typical Applications

Homegrown European Larch is regularly specified for projects including:

• Natural flood management (NFM)
• Leaky dams
• Woody debris dams
• Water attenuation schemes
• River restoration
• Wetland creation
• Peatland restoration
• Boardwalks
• Footbridges
• Viewing platforms
• Nature reserves
• Reservoir access infrastructure
• Estate management
• Forestry projects
• Countryside access improvements

Many of these schemes require untreated timber to minimise the introduction of preservatives into sensitive environments.

Large Quantities Available

One of Lanlee's key strengths is our ability to source significant volumes of homegrown European Larch.

We can supply:

• Structural posts
• Rails
• Sleepers
• Beams
• Boards
• Bearers
• Bridge timbers
• Boardwalk components
• Bespoke machined sections
• Cut-to-length timber packages

Available in numerous section sizes and lengths to suit individual project specifications.

Whether your requirement is twenty lengths or several hundred cubic metres, we can work with our UK sawmill partners to source the material required.

Bespoke Machining Services

Lanlee also offers extensive machining capabilities including:

• Cross-cutting to length
• Bespoke machining
• Chamfering
• Drilling
• Notching
• Profiling

Supplying ready-to-install timber can significantly reduce installation time on site.

Using Timber in Water – Important Design Considerations

Timber performance depends upon species selection, detailing, structural design and the service environment.

When specifying timber for use in or around water, the following should always be considered.

Freshwater vs Marine Environments

European Larch is commonly used within freshwater environmental projects.

For permanent marine exposure, tidal zones or highly aggressive environments, naturally durable hardwoods such as Greenheart or Ekki are often specified because of their exceptional durability and resistance to marine conditions.

We are happy to advise on suitable timber species for each application.

Environmental Requirements

Many projects undertaken for organisations such as:

• Canal & River Trust
• Environment Agency
• Natural Resources Wales
• Wildlife Trusts
• National Parks

Specify untreated or FSC® certified timber for environmental reasons.

Lanlee can source timber to meet these requirements where specified.

Correct Detailing

Good design is just as important as species selection.

Performance can be improved by:

• Avoiding water traps.
• Allowing timber to drain freely.
• Providing ventilation where appropriate.
• Using stainless steel or hot-dip galvanised fixings.
• Following recognised structural timber design standards.

Service Life

The expected design life should always be established during the design stage.

The suitability of European Larch will depend upon:

• Whether the timber is above water, intermittently wet or permanently submerged.
• Structural loading.
• Moisture cycling.
• Ground contact.
• Required service life.
• Client specification.

Where longer design lives or more severe exposure conditions are required, alternative naturally durable species may be more appropriate.

Our technical team can advise on suitable options.
