Our dock services

Dreaming of a brand new dock? Building a dock from scratch requires careful planning and the right construction for your location and intended use. We offer a variety of dock types – from suspended docks that require no water support to crib docks that rest firmly on the lakebed. Your choice depends on the water conditions and your preferences regarding stability and maintenance.

Whether you’re looking for a simple leisure dock or a durable structure for heavier use, we guide you through both the dock type and material selection to ensure a long-lasting result.

Has your dock been damaged by weather or time? We repair all types of docks, regardless of material or construction. We can replace posts, railings, or other worn parts, and reinforce existing structures to extend your dock’s lifespan and functionality. 

Did you know?
Whenever possible, we reuse the existing structure during repairs and renovations instead of building a new one from scratch. This method helps save both time and money.

Need to remove an old or damaged dock? We handle safe and eco-friendly dock removals, dismantling and transporting the structure with minimal impact on the surrounding environment. We also ensure all materials are recycled in an environmentally responsible way.

Dock with piles, crib, or poles?

Is a pole-supported dock right for your needs? For sandy, gravel, or muddy lakebeds, pole docks offer a stable and long-lasting solution. Poles are installed at regular intervals for optimal load-bearing capacity, with the number of poles adjusted based on dock size. For docks wider than one meter, three poles are typically used across for added support.

Poles are driven deep into the lakebed. A slight inward tilt increases stability and resistance against wind and wave forces.

A crib dock is a popular choice for its strength and classic appearance. Cribs provide excellent protection from waves and are ideal where the bottom is rocky or too hard for driving poles. Crib docks are also great for shallow water and can be customized to fit depth and substrate conditions.

What is a crib dock?
A crib is a large box-like structure made of heavy round logs, filled with stone to anchor the dock solidly to the bottom. It withstands ice and wave pressure effectively.

You can either fully cover the crib with decking and side panels or leave it partially exposed to showcase the craftsmanship. Either way, crib docks provide superior durability.

Tip:
As with other dock projects, we always evaluate whether the existing structure can be reused before building new, which often reduces time and costs.

Pile docks are ideal for soft, silty bottoms and sheltered areas with low wave activity. These structures rely on long piles – made from wood, steel, or concrete – driven deep into the substrate.

For optimal performance, piles are usually driven 8–10 meters deep, through sand, soil, or clay, until they reach solid ground or bedrock.

Pros and Cons of Pile Docks
✔ Cost-effective
✔ Durable when installed properly
✖ Less protection from waves since water flows freely underneath
✖ Susceptible to ice damage in winter, which may lift or sink the dock with changing water levels.

Choosing materials – best wood for docks

Det kan vara en djungel att veta vilket material som passar bäst när man ska bygga en brygga. Nedan hjälper vi till att guida kring val av trä och fästdon för optimal hållbarhet. 

Choosing the right timber and treatment is crucial for long-lasting docks. Round logs maintain their natural strength and resist water exposure well. Pressure-treated wood is essential for durability in outdoor and aquatic environments.

  • For freshwater or the Baltic coast: NTR/A-class treated timber

  • For the West Coast (due to marine wood-boring organisms): NTR/M-class treated timber

To extend the wood’s lifespan further, treat it with protective wood oil or alkyd-based paint to reduce cracking and preserve structure.

Fasteners are critical in dock construction. Since they are in direct contact with treated wood and moisture, high-quality materials like stainless steel are essential to avoid corrosion and ensure durability.

Hot-dip galvanized steel may be used for less exposed areas, but stainless or similarly corrosion-resistant metals are recommended for most structural elements.

Building permits – what to know before you build

När du planerar att bygga en brygga är det viktigt att känna till reglerna som kan påverka projektet, särskilt kring strandskydd, bygglov och anmälan om vattenverksamhet. Nedan hjälper vi er navigera kring var ni kan ansöka om detta och hur det fungerar. 

Swedish shoreline protection laws often require permits to build a dock – even on private land. The protected zone usually extends 100–300 meters from the shoreline. Always contact your local municipality before beginning your project to learn about possible exemptions.

You can read more on how to apply for exemptions at Boverket, Naturvårdsverket or County Administrative Board (Länstyrelsen.)

Depending on your dock’s size and use, a building permit may be required. For marinas or commercial use, permits are generally necessary. Smaller private docks often don’t need one – unless the site is protected. Check with your municipality for exact rules in your area.

ou must also notify the County Administrative Board of your water activity when constructing a dock. The board assesses if the project is suitable for the area, considering both environmental and private interests.

These include impacts on wildlife, water quality, heritage sites, nearby beaches, and neighboring dock owners.
