HELPFUL INFORMATION
GARAGE AND WORKSHOP SPECIFICATIONS
Our standard height buildings are 6'6'' high and are constructed using a high strength cement with steel reinforcing the panels are then vibrated to remove trapped air and strengthen the concrete mix , they are then decorated with a Derbyshire multi-spar . we also supply buildings with 7' high panels . We use a Hormann up and over door with steel frame 7' wide as standard but other sizes and styles are available . For the roof on the Apex garage we use a B5 swisspearl cement fibre roofing sheet with a galvanised steel roll top ridge , On Pent roof buildings we use a CR32 profile steel sheet with a polyester coating . There are steel supports (roof trusses ) every 4 ' on pent roofed buildings and every 6' on the apex roof.
GARAGE DOOR DRIVE THROUGH CLEARANCES
The drive through height of the up and over door in standard our 6'6'' panels with a standard canopy door is roughly 6'2'' or ( 1881 mm ) . And you get the full opening width depend on width of the door.
On the 7' high panel garages the drive through clearance is roughly 6'8" or ( 2034 mm ) .
For retractable doors which we have to use on larger widths e.g. 9' and 10' and also for use when the electric operator is fitted the drive through height on the door is reduced by 110mm - 140mm by the retractable mechanism , also importantly the width clearance is reduced by 4"-6" (100mm-150mm ) because of the lifting arms .
BASEWORK ADVICE
The concrete base is a very important part of the construction of a new garage/ workshop.
It needs to be flat and level , to ensure correct fitting of your building so things like the up and over door open correctly.
We recommend that the building is 3-4” overall longer and wider than the desired building size ( if room allows ) .
Ideally the base should finish slightly higher than the surrounding ground to keep excess water away .
Excavate approx 5-6” of earth , shutter out the external perimeter using a sturdy timber ensuring it’s square , measure the diagonal to all corners and they should be the same ( as per diagram) .
Lay a compacted sub base such as a MOT type 1 hardcore aggregate.
Then lay 4” concrete to a depth of 4-5” , using a tampered finish to the concrete , laying a beam across the shutter boards to leave a slight rippled pattern moving up and down the shuttering, then use a trowel around the external edge of the concrete to leave a smooth edge .
