Tiny & Mobile Homes
Tiny Home & Mobile Home Foundations in Chilliwack
A tiny home, mobile home or modular building needs a base that stays level for years without a concrete pour. Postech helical screw piles give it exactly that: a set of engineered steel piles driven to firm ground, with the home set on top at the right height.
We build these foundations for tiny homes, mobile and manufactured homes and modular structures across Chilliwack and the Fraser Valley, including lakeside and hillside sites where access is limited.
Why screw piles for tiny & mobile homes
Level and stays level
Piles are installed to the elevation your home needs and fine-tuned in the field. Because they reach firm ground, the home is not at the mercy of soft or seasonal surface soil.
Works on slopes and awkward sites
Pile heights are adjusted individually, so a sloped lot does not need heavy grading or retaining walls just to get a level base. Compact equipment can be used where access is tight.
Fast, and no curing time
Most residential projects are completed in a day. With no concrete to cure, the home can often be placed shortly after the piles go in.
Removable
Piles can be unscrewed if the home is ever moved, which suits mobile and relocatable buildings.
The right pile for the job
The right pile depends on how heavy the home is, how many support points it needs and the ground underneath. Our range runs from the P238 (60.3 mm shaft, up to 15,000 lbs) through the P278 (73.0 mm, up to 25,000 lbs, our pile for homes and additions) to heavier models for larger buildings.
Every installation is backed by engineering documentation, and Postech piles hold Canadian Construction Materials Centre (CCMC) certification, conforming with the National Building Code and CSA standards.
Built for Fraser Valley ground
Many tiny and mobile homes in our area sit on hillsides, near lakes or on acreage with soft ground. Our Ryder Lake tiny home project is a good example: the photos in our gallery follow the piles, the lift and the final placement.
In rocky ground, such as around Harrison and the Columbia Valley, pilot-pointed piles penetrate with precision. In wetland-adjacent soils near Cultus Lake and Agassiz, the piles reach stable strata below the soft layer.
How installation works
- 01
Mark and check
We mark the pile locations and verify elevation points before the first pile goes in.
- 02
Install and monitor
Each pile is driven in with our equipment, which monitors torque so we can confirm it reaches the soil strength it was chosen for.
- 03
Set to height
Piles are cut or adjusted to the exact height, so your structure starts level, even on sloped ground.
- 04
Build right away
There is no concrete to cure, so your crew can start building as soon as the piles are in.
What a typical project looks like
Start with the location, a rough description of the home (its size and weight, if you have them) and a few photos of the site. We reply within 24 hours with next steps and arrange a site visit if one is needed. The pile positions are laid out to match the support points of your home.
On the day the piles are installed and set to the exact height, with torque monitored, and the levels are checked before the home arrives. Our Ryder Lake tiny home project in the gallery shows this sequence: the piles, the lift and the final placement.
Planning your project
- Get the home's weight, dimensions and support points from the builder or manufacturer. The pile layout is based on them.
- Decide the finished height of the floor above the ground, including any skirting or steps.
- Confirm how the home will be delivered and placed, and whether a crane or truck needs access to the pad.
- Check permit and zoning requirements with your municipality before you order. We can supply engineering documentation when it is required.
- Have underground utilities located before any ground work. BC 1 Call is a free service.
