All of our conservatory base foundations are fully insulated and damp proofed. They are laid by very experienced professional builders who have worked in the industry for many years and laid a vast quantity and variety of conservatory bases.
Stage 1 Footings
Firstly the site is cleared in preparation to dig the footings.
Then a trench is dug 450-900mm deep (depending on Soil Conditions) and 450mm wide.
The trench is filled with Grade A concrete and allowed to go off overnight.
Stage 2 Floor Slab
Lay engineering bricks up to damp course level.
A damp proof membrane is then laid to cover the whole floor up to damp course level.
On an average base of 3m x 3m a tonne of hardcore is then used to form the foundation for the concrete floor slab. The hardcore is whacked and compressed down.
Then 100mm Floor Insulation is put down.
Back filled with 100-150mm of Grade A Cement (Ready Mix) which conforms to All Building Regulations.
This is then Float Finished to leave a smooth surface.
Stage 3 Dwarf Wall
Build up 8 Courses (600mm) with a Twin Cavity Wall, which is 250mm thick.
2 x Brick @ 100mm with a 50mm Cavity (Fully Insulated).
The bricks used will be the Best Match to the Property.
