Hello,
I have installed six pier foundations in several stages underneath our terrace. Two pergolas from Pergolux will be set up here.
The foundations measure 40x40 cm (16x16 inches) or 50x40 cm (20x16 inches) and are each about 50 cm (20 inches) deep. Below them is a gravel layer approximately 30 cm (12 inches) thick.
The oldest foundation is about 8 days old, the newest one 4 days.
In recent days, the temperature has been around 10°C (50°F), sometimes up to 14°C (57°F), but at night it has dropped to around 5°C (41°F).
When can I start assembling the Pergolux and secure it to the foundations? The attachment will be done using stainless steel (V4A) concrete screws. Each Pergolux weighs about 200 kg (440 lbs) fully assembled. The larger foundations each support both pergolas placed side by side.
Thank you very much.

For the floor, I used stainless steel concrete screws sized 8x105.I’ll be starting the assembly soon as well. Do you remember how wide the holes for the screws were or should be? Was 8 mm (0.3 inches) ideal? I couldn’t find anything on the website, only “…with anchor bolts at least 140 mm (5.5 inches) long.”

Coletrickle_78084 May 2024 17:58The holes were, I believe, 8mm (5/16 inch), and the screws were then 10mm (3/8 inch). Here, 8 does not indicate the screw diameter, but the diameter of the drill hole.

I would also like to get some opinions on this topic! We have paved our terrace with heavy concrete slabs measuring 100cm x 100cm x 5cm (39 inches x 39 inches x 2 inches). Each slab weighs about 115kg (254 lbs). I want to build a Pergolux pergola, freestanding but partly attached to the house, sized 3 x 4 meters (10 x 13 feet). I would like your opinion on whether I can simply screw the pergola to these heavy slabs, considering they would provide about 460kg (1,015 lbs) of counterweight. What do you think?

.... after all, that would be about 460kg as counterweight...Hello,
in the worst case, that might not be enough. I was strongly advised to assume 70kg/m² (14.3 lb/ft²) as the uplift load if no information about uplift forces is provided. This is a very conservative value, including a significant safety margin.
A quick calculation gives:
4.00m (13.1 ft) x 3.00m (9.8 ft) = 12.00m² (129 ft²) roof area
12.00m² (129 ft²) x 70kg/m² (14.3 lb/ft²) = 840kg (1852 lb) uplift force
840kg (1852 lb) - 460kg (1014 lb) (self-weight of the panels) = 380kg (838 lb) excess uplift load
Result: if the canopy weighs more than 380kg (838 lb), it should not be lifted off in strong winds.
