Conservatories are only as strong as the foundations they are built upon. They can decrease if they aren’t on a protected footing. Even single-storey extensions and conservatories require deep foundations to stand strong for as long as possible. That implies needing to dig to a substantial depth and after that building a base from essential elements.

Before you remove the structure, ensure that you have the ideal planning approval for the develop, if required. Also be sure that your installer has the abilities and experience needed to develop a strong structure.

How Deep Should the Structure Be?

There are a number of elements that go into identifying the necessary depth of the conservatory foundation. Things like the condition of the soil, any close-by trees, rivers, and railway can all affect how you need to prepare ground before gazing building and construction. Another thing to look for is any obstructions that need to be avoided, such as a drain cover.

In regards to averages, we would recommend that you dig at least a metre deep and then fill the trench with concrete for optimal strength. The ideal depth is better to 1,500 mm difficult, which is the perfect depth for a routine extension. That is because modern-day conservatories and orangeries are made from more substantial products.

A brick cavity wall for the conservatory is developed onto the structure, which need to be insulated with 75mm of wall insulation.

Stacked Foundations

When handling loose soil conditions, it may be needed to strengthen the foundation utilizing piles. These steel rods break through the loose soil and are driven into the ground to appropriately distribute the weight of a conservatory on loose soil to establish a solid structure.

Conservatory Base

A conservatory base is made from a layer of ‘hardcore’ which is covered in a layer of sand. Hardcore describes a strong product, such as stone, that has actually been taken and squashed and set out on top of a concrete structure to form a level base. It’s suggested that you have at least 150mm of hardcore within the foundations of your conservatory. The compacted hardcore is set out over a layer of sand to establish an even surface area.


This special layer of damp-proof material covers the base to avoid wetness from the ground listed below the structures from seeping into the foundation.

Floor Insulation

A thick insulation layer goes on top of the damp-proof layer to guarantee heat does not go down through the flooring. We recommend that you use an insulation layer between 70-100mm thick for finest results.

Smooth Screed Flooring

Finally, a smooth layer of concrete is poured over the base. It is strengthened with steel prior to the floor screed is applied. This is made from cement or a combination of cement and sand. Screed is “smoothed” into location with a leveling board over a raised lumber bed. This layer assists guarantee that the conservatory floor is flat and smooth.

After all of this is done, the conservatory is prepared for wooden flooring, tiles, or carpets. And the glazing is clearly a very important part of the conservatory. So employ an excellent professional glazier.
