ᐅ Construction of Parking Spaces for Cars and Waste Disposal Areas – Quantities and Procedures?

drooperHello everyone.
I am new to the forum and would like to have a plausibility check for my planned project, as I am a bit unsure.
A brief introduction… I have owned a beautiful house from 1900 for about a year now, which was partially renovated in 1994. The first floor is now mostly finished, and the outdoor area will be developed gradually. This is exactly where I would appreciate a reviewing eye on my plans.
The plan is to build or prepare a parking space for two cars, including an area for garbage bins, so that paving and the construction of a carport can take place at the beginning of 2018.
The total area measures 9m x 6m (29.5 ft x 19.7 ft) and is currently covered with grass and weeds. This is how I intend to proceed and what I think the required amount of materials will be:
- Excavation of the area to a depth of about 40cm (15.7 inches)
- Fill the bottom layer with approximately 25cm (9.8 inches) of fill material (0/32) — is that enough or would more be better? → 13.5 cubic meters (476 cubic feet)
- Compact the area
- Install edging boards (30cm (11.8 inches) deep, 8cm (3.1 inches) wide), paying attention to a well-defined back support → 30 meters (98.4 feet) (setting in lean concrete with retardant; how much do I need?)
- Middle layer of crushed stones about 5cm (2 inches) (0/16) → 2.16 cubic meters (76 cubic feet)
- Compact the area
- Top layer of gravel bed about 3-5cm (1.2-2 inches) → 2 cubic meters (71 cubic feet)
- Compact the area
At the end, there should be about 8cm (3.1 inches) of space above the edging so that 8cm (3.1 inches) high pavers will align flush with the edging.
For excavation waste, I am theoretically calculating 9m x 6m x 1.3m = approximately 55 cubic meters (1,940 cubic feet). Since I want to reuse some of it elsewhere and a friend will take some as well, I am planning with 50 cubic meters (1,765 cubic feet).
What do you think about this?
Best regards

Hello drooper
40cm (16 inches) deep is too shallow for me. The frost can still reach underneath.
Why do you want retarders in the lean concrete? Make a 1:4 mix, properly moist, and then tamp it down. That will last forever.
The gravel is just being leveled. You can’t compact it.
Excavation area times 1.3. I think the factor will be higher.

Hi Steven,
Thanks a lot. I hadn’t checked in for a long time as I thought no more answers would come here.
How deep would you go? I can do lean concrete without a retarder. What ratio should I specify to the ready-mix plant with the 1:4 (which refers to what exactly)?
I’ve heard from someone that using a geotextile fabric can save about 10cm (4 inches) of excavation. It is laid down before placing the fill and is supposed to somewhat reduce frost penetration upwards. However, I couldn’t find any information about this online. Is there any truth to that?
Would there actually be any objection to using a single fill layer of 0/45 instead of two separate fill layers of 0/32 and 0/16?
Best regards,
Marcus
