Building a greenhouse foundation is a crucial step in extending the growing season and ensuring the structure stands up to high winds and frost. There are various foundation options, including concrete, brick and rock facades, plumbing, electrical, and heating. To build a wooden greenhouse, you need to decide on the dimensions, select a structure, choose the proper door and entryway, find a covering, create the floor, and gather building materials.
To create a wooden greenhouse, you will need to decide on the dimensions, select a greenhouse structure, choose the proper door and entryway, find a covering, create the floor, and gather building materials. Railroad ties are a good option for a reliable foundation, and a simple platform with two levels is essential. To reinforce the foundation, drill holes and hammer in re-bar to secure the first level.
There are two types of perimeter bases: wooden and concrete. Wooden perimeter bases are made from breeze blocks, paving slabs, wood, or concrete. The greenhouse base can then be made from breeze blocks, paving slabs, wood, or concrete.
In summary, building a greenhouse foundation requires careful consideration of the climate and soil conditions, as well as the use of materials like pressure-treated wood or naturally resistant wood.

How many years do railroad ties last?
Railroad ties, crossties, or wooden sleepers are made from wood and treated with a preservative to last 30 years or more. They are used in railroad tracks, such as those with creosote preservative, which runs through forests. Despite technological advancements, wood still dominates over 93 of railroad track applications, despite the use of other materials like concrete, steel, and plastic composites.
What base is best for a greenhouse?
A concrete base is a long-term solution for greenhouses, offering stability and rain-resistance. It protects against burrowing rodents and is a long-term solution. A raised gravel base prevents waterlogged soil around the base. Timber frame bases with insulation are recommended for maintaining a consistent temperature and preventing frost damage. High-quality insulation, such as foam boards or bubble wrap, helps retain heat and prevent frost damage.
What chemicals are in railroad ties?
Creosote, a wood preservative derived from tar distillation, is used in pesticide products to protect outdoor wood from termites, fungi, and mites. The EPA conducts a registration review every 15 years for all pesticides to ensure they do not pose unreasonable risks to human health and the environment. The Interim Decision (ID) implemented additional mitigation measures to protect workers applying creosote. Other approved preservatives, wood-alternative and composite materials, and species of wood resistant to pests are also used.
How to build the base for a greenhouse?
To build a concrete base for your greenhouse, follow these steps:
- Mark four corners at the size of your greenhouse with stakes.
- Level the ground by ensuring the soil is leveled before building the wooden perimeter.
- Pour the concrete and assemble the greenhouse.
- If you have an existing deck or concrete slab, create a concrete base from scratch.
- It is recommended to calculate a 6-inch height.
Does a greenhouse need a solid base?
A solid concrete base is the most practical and durable foundation for greenhouses, suitable for large ones and easily set above ground level. It can be easily maintained and kept clean with a broom, and can be washed down with detergent to prevent diseases. Rodents cannot tunnel inside the greenhouse. Standing water may be a problem, but drilling drainage holes can prevent issues. This is the most expensive option, but it is relatively easy to construct once shuttering is placed. Stronger fixings, such as expansion bolts, can also be used to hold the base in place. Once the site is prepared, it’s time to construct your greenhouse and start growing.
Can you make a raised garden bed with railroad ties?
The use of railroad ties for the cultivation of edible plants is inadvisable due to the potential for chemical contamination of the soil, which could ultimately result in the contamination of food products. Nevertheless, railroad ties can be utilized in landscaping with ornamental plants, provided that they are not employed for food production.
Is it safe to build with railroad ties?
Railroad ties have been used as a cheap solution for retaining walls in residential and commercial properties for decades. However, these ties pose a significant health threat due to the use of a chemical called Creosote, which is created when coal is heated to produce coke or natural gas. This process produces coal tar creosote, coal tar, and coal tar pitch, which can get into plants, soil, and ground water due to the heat in the South.
Creosote has been classified as a probable carcinogen by the Environmental Protection Agency (EPA), with studies showing increased risks of cancer and respiratory problems in plant workers exposed to it.
Exposure to creosote on the skin can cause rash, irritation, and even cancer. Although the EPA pushed for tougher legislation in 1986 to stop the use of creoste, timbers used before this time period still contain this chemical in their use.
How long does it take for railroad ties to rot?
Wooden railroad ties, crossties, or wooden sleepers are durable and environmentally friendly. They are made from wood and treated with a preservative to last for over 30 years. Although technological advancements have allowed for crossties made from other materials like concrete, steel, and plastic composites, wood still dominates over 93 of railroad track applications. These ties are used in railroad tracks to ensure safety and longevity.
Are railroad ties bad for the environment?
Railroad ties are treated with chemicals that can pose a threat to trail development. One common treatment is creosote, which penetrates deeply into pressure-treated wood and can leect soil, kill plants, insects, and small animals, and pollute the local watershed. It is not intended for landscaping and should not be used along the trail.
Wood coated in chromated copper arsenate (CCA), a green preservative, is even more dangerous. It protects against rotting with chromium, copper, and arsenic, but the toxic arsenic in the wood is a danger to plants and wildlife. CCA-treated railroad ties should be disposed of through municipal means.
Soil surveys may reveal other severe issues, such as lead and arsenic, produced from coal ash and cinder. Severity and depth can be determined by continued soil surveys. Solutions range from removal and replacement of top soil or clay to the construction of an impervious surface to prevent further leeching or harmful contact for trail users and neighbors.
Is it safe to use railway sleepers for raised beds?
Railway sleepers are generally safe for vegetable gardens and flower beds, but reclaimed sleepers soaked in creosote are not recommended due to potential leaching into the environment. To ensure sturdy borders and beds, dig a small trench and add concrete mix before laying sleepers. Laying sleepers directly onto soil would leave them unprotected from ground movement and accelerate decay. Top tips for laying railway sleepers include digging a shallow trench and adding concrete mix for a secure and long-lasting solution.
Why not to use railroad ties?
Despite the well-documented carcinogenic properties of railroad ties, they continue to be sold for a variety of purposes. However, garden centers have ceased to stock them and advise against their use in proximity to gardens, lawns, or residential properties. Such materials were previously deemed suitable for use with flowers, but not vegetables.
📹 How to Landscape with Railroad Ties
Hey guys, in this video I will show how you can use railroad ties for landscaping. This is a great way to clean up your gardens, …
Great article Once again. Thanks for the tips on pinning down the ties, needed that. Only change I’d recommend is not to use any plastic barriers for your yard or land, instead you can use a biodegradable & water permeable cloth or like cotton or burlap or just cardboard (seriously)… and if you must use plastic, definitely get those semi-permeable weed barriers for hardscapes like this. Plastic leaves small areas of sitting water on top… and has a really bad decomp potential overtime, leaching etc, it often ruins the soil health of the layers directly below it. Very large roots tend to be the only ones that survive under these areas. Plastic also encourages ants, termites, pill bugs to nest underneath, plus beatles & crickets which aren’t too bad unless they attract rodents. I know first hand bc it was an expensive issue with our current house’s front garden. I know a garden is very different case but same principle with negative outcomes.. long story cut short, the previous owners had just kept putting new plastic & new layer of bagged soil for 40 years until nothing would grow… a back hoe & dump truck were needed to solve it.
I am wondering, do you have any problems with deer or woodchucks/gophers? Does the wood in the base help, if so? What are your thoughts on modifying the beds to include a heavy screen in the base? I have deer and woodchuck problems. I would add an upper screen system. Thank you for your help here, it looks great! Is there any way to tell us the costs that you had?
Railroad ties have been used the past few decades as a cheap solution for retaining walls in residential homes and commercial properties. What homeowners don’t realize, is that these cross ties are not only harmful to the environment, but they pose a huge health threat! Ensure they’ve been responsibly sourced and properly treated for residential use, particularly if you’re planning to use them in a vegetable garden or close to water sources. The risk of using railroad ties, treated with creosote, a known carcinogen, primarily comes from direct contact, inhalation, or ingestion. Here are the precautions that should be used when handling railroad ties: Handling: When handling creosote treated wood, wear gloves and long sleeves and try to minimize time spent working with ties. Work in well ventilated areas and avoid working in hot conditions when vapors are most potent. Children: If children play on or around the ties they may get creosote on their skin and clothing and could subsequently ingest small amounts. Exposure to skin can cause irritation and rashes. Ingestion in small amounts while not life threatening, is a health concern. Gardens: Plants have shown only limited potential to take up creosote but some compounds have been shown to attach to roots, which could lead to elevated creosote levels on tuber vegetables. For this reason, it is advisable not to landscape with railroad ties directly in contact with vegetable gardens. Water Table: Some components of creosote are very sticky and not water soluble and will stay on the ties; however, other chemicals are water soluble and will dissolve and move with water.
