Installations currently have a lead time of up to 28 days. Once your installation questionnaire has been approved, our installation team will be in touch to arrange a date with you. 

Why not let our team of experts take care of installation of your new garden building? All you have to do then is sit back and relax.

The installation service includes: Locating the packed building on site, constructing to manufacturers standards, applying the roof covering, clearing away excess packaging and tidying up.

Please note: A flat level base needs to be in situ before the installation can take place; we will kindly request photo confirmation of your level base, as well as proof of ample access, to ensure our fitters can install your new garden building without a hitch. We have created this handy How to Build a Base guide, to help you choose the best option.

In addition to this, a 60cm clearance around the building is required. This is to ensure our installers have plenty of room to install your new building in its chosen location, to ensure the building has adequate airflow throughout its life and also to allow easy access for annual maintenance. 

When you place your order, you will receive a questionnaire so you can tell us all about your garden so we can ensure it'll be the ideal spot for your new building. Once the level base has been confirmed by our team, your order will be passed onto our delivery and installation team who will arrange a delivery and installation date(s). Our installation teams operate nationally, so it may mean we deliver and install on different days due to team scheduling. Please visit our Installation Service Page for more information.

Create a strong, sturdy and most importantly level base for your shed or garden building with the Waltons Portabase. Made from high quality pressure treated timber it can be assembled and installed in minutes, mounting the wooden frame on the galvanised metal spikes included. Providing a raised platform on which to mount your building, it protects from damp and solves the problem of uneven or sloping ground. Please note this is not a floor, all our buildings are supplied with a floor as standard.

What is pressure-treated timber?

Pressure-treated timber undergoes a preservative process that enhances its durability and protection. This involves placing the timber in a vacuum chamber to remove all the air from its cells. Subsequently, chemical preservatives are forced deep into the wood under pressure. These modern preservatives are environmentally safe and provide numerous benefits.

These benefits include:

Improve your building's lifespan

Untreated timber decays much faster than treated timber. The pressure treatment process creates a protective shield around the wood, making it suitable for outdoor use year-round, as it is safeguarded against rain, hail, and snow.

Protection from the elements

Untreated wood in moist or wet conditions tends to soften quickly, making it susceptible to fungi, bacteria, and other microorganisms that cause decay. Even minimal moisture can lead to fungal growth. The powerful preservatives used in pressure treatment have anti-fungal and anti-insect properties that penetrate deep into the wood, protecting it from environmental decay.

Minimal upkeep and maintenance

Pressure-treated timber requires minimal maintenance. Its resistance to insects, water, and fungi means there is little to worry about, making it a low-maintenance option for gardens and outdoor spaces.

Great value

While pressure-treated timber is initially more expensive than untreated wood, its broad spectrum of protection makes it more cost-effective in the long term due to its extended lifespan.

Ecologically friendly

Despite being preserved with chemicals, pressure-treated timber has environmentally friendly qualities, primarily due to its longevity. The increased lifespan means fewer trees need to be harvested for replacement products. Additionally, the treatment process uses copper reclaimed from the recycling industry, reusing an element that would otherwise be discharged into the environment.

Attractive finish

Pressure-treated timber maintains its natural beauty without needing multiple coats of paint or preservatives. This natural look is appealing to many homeowners and makes wooden products a popular choice for gardens. For those who prefer a more colorful display, the timber can be easily painted or stained after weathering, allowing coordination with garden colour schemes while maintaining the timber's deep protective layer.

Replace the standard mineral felt with our Superior Upgraded Rubber Roofing, also known as EPDM (ethylene propylene diene monome).

What are the benefits of upgrading to EPDM?

• Easy installation
  • EPDM roofing is crafted for easy installation, featuring fewer seams compared to other roofing types such as standard felt. This streamlined design simplifies the installation process, making it a quick and easy element of the overall build. Additionally, EPDM roofs are durable enough to support foot traffic, ensuring a thorough and precise installation.
• Stands the test of time
  • EPDM rubber roofing is made from durable materials specifically designed for long-lasting performance. Ideal for flat roofs, it effectively prevents water infiltration and leaks, making it a popular choice for those seeking peace-of-mind with a reliable waterproof roof covering. EPDM remains flexible and resilient even in harsh and changeable British weather conditions. Unlike other roofing materials that can crack or shatter in extreme cold, EPDM maintains its integrity and durability over time. This long-lasting robustness ensures that your investment in EPDM roofing is a smart choice, providing protection for your garden building for decades to come.
• Lightweight and flexible
  • The lightweight nature of EPDM ensures it doesn't add undue stress to your garden building, even in tough weather conditions. 
• Minimal maintenance 
  • Unlike traditional roofing materials such as felt, and bitumen, EPDM requires significantly less maintenance after installation. Its waterproof membrane remains permanently flexible and has a lifespan that matches the material with expectancy of up to 50 years. 
• Weather Resistance
  • When installing a new garden building and entrusting it with your belongings, it's crucial to ensure your roofing material is weatherproof, particularly for older roofs that may be deteriorating. Leaks can cause extensive interior damage, timber rot and structural issues, especially if the roof can't handle pooling water. EPDM roofing is highly resistant to external elements, preventing water from entering your new garden building and providing long-term protection. Additionally, EPDM effectively repels algae growth, addressing common moss issues on roofs.
• Energy Efficiency
  • When properly installed, EPDM helps to attract the sun’s heat, keeping your building warmer in cold weather. 
• Good for the Environment
  • EPDM is an excellent choice for those committed to a greener environment. Rubber, or EPDM, is widely used in various applications, making it easier to recycle.
