First, install stakes and stretch a string. For approximate measurements, measure the available slope at the pile installation locations.
We recommend leaving the screw foundation above the ground by no more than 20% of its working length. If the slope is up to 20 cm, you can use the same screws – screw one row completely into the ground, and leave the other above the surface (without exceeding the recommendation). For larger slopes, choose taller screw piles.
Which screw pile is suitable for a terrace?
For terraces, we typically use U-type screw piles: 885 mm in length for harder soils and 1000 mm in length for softer soils.
If the soil at the installation site has been recently disturbed, we recommend using longer piles.
Unused screw foundations can always be returned. Additionally, you can always exchange the piles for ones that better suit your needs.
Will frost lift the screw piles?
Frost lifts from below, but screw foundations are harder to lift due to the pointed tip in the ground. For structures that could be affected by soil movement, we recommend using screw piles at least 1000 mm long.
In Lithuania, the ground typically freezes about 25 cm deep in the east and 15 cm in the west. A snowless winter with temperatures of -25°C for an entire month is required to freeze the ground to 60 cm.
Can you install them?
Yes, we install them throughout Lithuania. Call +370 652 09611 – we’ll arrange a time and price.
How much does installation cost?
With the location, quantity, and screw pile dimensions, call +370 652 09611 – we’ll agree on a price.
Which screw foundation is suitable for a house or small building?
To recommend the best solution, please provide the building dimensions, possibly its weight, and the soil type where it will be placed. Call or write – we’ll choose the most suitable option.
Examples:
A 5×5 m house will require 12 screw piles for the perimeter.
If the building is a frame with a floor, it typically needs 16-18 screw foundations.
How quickly will I receive my order?
All orders placed by 3:00 PM will be delivered the next day.
How to prepare for screw pile installation?
1. Mark the installation points on the ground. 2. You can drive in auxiliary tools or the screw pile itself at the planned locations. 3. After marking, measure the diagonals between the points.
Before starting to screw in the galvanized foundation, we recommend checking the site for possible obstacles (stones, roots, etc.). An electric perforator (drill is included in the rental set) is best for this. You can also check by driving in rebar.
What to do if you encounter an obstacle in the ground?
The most common obstacle is a stone, which can be broken with a perforator. If the obstacle is larger or you don’t have the right tools, consider shifting the installation points to avoid the obstruction.
What electric tool is needed for turning the reducer?
Regardless of the quantity, we always recommend using a more powerful drill or perforator or taking breaks to prevent the tool from overheating.
The perforator is the best choice as it comes with a drill for checking the installation points.
How to return rented equipment?
Upon receiving the equipment, you’ll get two return stickers.
After finishing work, make sure all equipment is placed in the box.
Stick one label on the equipment box and the other on the supporting beam.
You can return the equipment by:
Taking it to your local Venipak parcel drop-off point.
Calling us to arrange for a courier to pick it up from the same address where the equipment was delivered.
How long does it take to install one screw foundation?
Installing one screw foundation without obstacles takes 3-10 minutes. Allow extra time for preparation. You can install around 50 units of 1000 mm long screw foundations per day.
What are the advantages of screw foundations compared to concrete ones?
A screw foundation requires:
Site preparation
Electric or manual tool
A concrete foundation requires:
Tool for drilling holes
Concrete mixture
Water
Pipe formwork for piles
Reinforcement
Anchor
Once a screw foundation is installed, you can immediately continue work, whereas a concrete foundation requires waiting for the concrete to set.
Can I return the products?
Yes, in accordance with the law, you can return or exchange products within 14 days from the delivery date.
