Tallinn's #1 terrace builder
Terrace construction and care in Keila
Terrassiehitus Tallinn builds timber and composite terraces in Keila, installs screw pile foundations in clay soil, and repairs and oils older terraces. We work in the town centre and on newer plots along the Keila River towards Keila-Joa. By the end of 2025, we had completed 73 jobs in Keila: 41 construction projects and 32 maintenance or repair jobs.
We bring beams and boards from Peetri in a single trailer trip; Keila town centre is 38 km from our warehouse. On riverside plots, we raise the decking 60 cm above ground because spring floods can lift the Keila River 40 cm above its usual level.

Clay soil and riverside plots in Keila
Keila's clay till holds water and heaves when it freezes. Ice lenses can lift a concrete block resting on the ground, leaving a terrace corner at a different height each year. We install screw piles with their helical plates below the estimated 1.2 m frost depth. Even if the target torque is reached sooner, we drive each pile to its full depth so frozen clay cannot lift a short pile and the terrace above it.
Spring meltwater can remain beneath riverside terraces for weeks, and clay dries slowly. Without airflow, moisture under a low terrace can damage the beams faster than on a dry sandy site. We lay geotextile and a 5 cm layer of crushed stone beneath Keila terraces, leaving at least 30 cm between the decking and the ground for ventilation. A hand-auger test hole struck glacial boulders on 23 of our 41 Keila construction sites.
Our services in Keila
Clay soil and the river influence how we build in Keila. Every quote begins with a check of the ground and site levels. These six services cover the work from foundations through to maintenance.
Wooden Terrace Construction
For a timber terrace in Keila, we first measure the site's slope. On clay, rainwater needs to drain away from the house rather than collect between the foundation and plinth. Before installing the first pile, we grade the ground beneath the terrace to a 2% fall away from the house.
Composite Terrace Construction
Composite decking suits riverside sites because the boards do not absorb spring moisture or rot above standing meltwater. The timber frame beneath them is still vulnerable to prolonged damp, so for riverside terraces we offer an anodised aluminium frame.
Terrace Foundation
We begin a foundation in Keila's clay till with a hand-auger test hole. Glacial boulders can stop a screw pile before it reaches frost depth, so we mark the depth of any obstruction on the pile plan.
Terrace Oiling and Maintenance
On damp, shaded riverside sites, moss and algae can make timber decking slippery when wet, even by its second summer. We remove this growth and let the washed boards dry for 24 hours before oiling.
Construction of shelters
Clay heave can tilt a shelter post and send roof runoff towards the wrong edge. Our Keila shelter quotes show the direction of roof drainage and the gutter position, so you can see where water will go before construction.
Terrace Repair
For an older terrace on ground-level blocks, we level the corner shifted by winter frost. We replace the affected blocks with screw piles and refit sound decking in its original position.

Free site surveys in Keila
Our van and trailer can reach central Keila from the Peetri warehouse, 38 km away via the Tallinn ring road, in 35 minutes. Site surveys and quotes are free in Keila; the €0.87 per kilometre travel charge applies only beyond Harju County.
Beams, decking and gravel come on a trailer. In the direction of Keila-Joa, where the road narrows, we measure the width of the gate before confirming the order and check whether the trailer can turn around on the lot.
Frequently Asked Questions
What does a terrace foundation cost in Keila?
A foundation with ten screw piles starts at €550 in Keila, at €55 per pile. A 1 m extension adds €47 per pile. The test hole, pile plan and quote are free because Keila is in Harju County.
Can you survey a Keila site in the evening?
Yes. We can survey a Keila site and make a test hole on weekday evenings until 19:00. The office answers calls weekdays from 08:00 to 17:00, and our construction crew works in Keila on weekdays.
Where in Keila do you build terraces?
We work across Keila, from central timber-house gardens to riverside streets and newer homes, and in nearby villages towards Keila-Joa and Vasalemma. Surveys are also free in Vasalemma, 12 km from central Keila.
When can work begin on a clay plot in Keila?
We reply to Keila enquiries on the same working day, and pile installation begins no later than the 14th working day after an order is confirmed. In spring, a test hole lets us check that the clay has thawed before installation; a partly frozen layer can give a misleadingly high torque reading.
